Built and maintained in Singapore by Olano — the olano.ai platform for applied AI, and olano.sg, our Singapore AI studio. Singapore MCP is the studio's open contribution to the local AI community, and it is free to use under the MIT licence.

Singapore MCP is an independent community project. It is not affiliated with, endorsed by, or an official product of the Singapore Government or any government agency. “Official” below describes an upstream data source, not this software.

Overview

Singapore MCP is a read-only bridge between an AI client and Singapore's official public data: data.gov.sg, OneMap, LTA DataMall, and SingStat. Every answer keeps its source agency, dataset identifier, observation period, units, and freshness caveats, so you can check the work. Most of it runs with no API key at all.

The monorepo separates provider access, reusable analysis, and user-facing workflows. Install the aggregate server for the complete experience or a focused executable when you only need one provider.

Focused stdio/HTTP executables are available for the aggregate, data.gov.sg, OneMap, LTA, weather, and rail packages. The other packages are reusable registration libraries composed by the aggregate server.

Example questions

Ask these in an MCP client, or use olano-sg examples [category] to browse the packaged prompt catalog. Results depend on upstream coverage and, for a few tools, on the optional keys in Credentials and caching. Not installed yet? Ask a few of these on Telegram first with @OlanoSGBot, or go straight to Quick start.

Companies and ACRA

• “Find the official public ACRA records matching Olano and show the UEN and entity status.”
• “Look up this exact UEN across all ACRA shards; make any match uncertainty explicit.”
• “Compare monthly business formations and cessations, then calculate net formations.”
• “How have formations changed for two SSIC sectors over matched periods?”

HDB and private property

• “Show recent 4-room HDB resale transactions in Bedok and calculate the median and quartiles.”
• “Compare HDB resale price per square metre between Tampines and Jurong East.”
• “Find HDB carparks whose address contains Bishan and group them by carpark type.”
• “Show bounded private-property transaction evidence for a project or district.”
• “Build a property-area brief for Queenstown with OneMap location context.”

The first example is a single MCP operation. hdb_resale_stats applies the exact town and flat-type filters, selects the latest available matching month by default, returns the transaction rows, and calculates the range, median, Q1, Q3, and price per square metre inside the server:

npx -y @olano/sg-cli tool hdb_resale_stats '{"town":"BEDOK","flatType":"4 ROOM"}'

Use latestMonths, startMonth, or endMonth to choose a different period. A direct dataset download is not required. This operation is available in the aggregate server's all and property profiles; it is not part of the focused @olano/mcp-datagov row-reader package.

COE, buses, roads, parking, and taxis

• “What is the latest Category B COE premium, quota, number of bids, and bid-to-quota ratio?”
• “Show the last 12 Category A bidding exercises and changes from the prior premium.”
• “When are the next buses arriving at this bus stop?”
• “List current traffic incidents and nearby traffic-camera images.”
• “Show live LTA carpark availability and taxi availability.”

MRT and LRT

• “What are the MRT/LRT codes and line connections for Paya Lebar?”
• “List every station on the Thomson-East Coast Line.”
• “Which official station exits belong to City Hall?”
• “Find the five nearest rail stations to latitude 1.29027, longitude 103.851959.”
• “Find rail stations near 1 Fullerton Road and state whether distance is straight-line or walking.”
• “List MRT/LRT interchanges and show the date of each bundled source snapshot.”

Weather, PSI, rainfall, and dengue

• “Show the current two-hour forecast for Singapore areas.”
• “What are the latest temperature and rainfall readings by station?”
• “Show the 24-hour forecast, four-day outlook, and latest PSI readings.”
• “Find current dengue-cluster records and include the dataset freshness.”

Education and childcare

• “Find MOE schools matching Nanyang and show the official dataset fields.”
• “Find ECDA childcare centres in an area and summarise any published vacancy fields.”
• “Resolve this address with OneMap before comparing nearby school or childcare records.”

GDP, prices, labour, income, FX, tax, and trade

• “Show the latest GDP growth observations and compare selected industries.”
• “Calculate year-on-year CPI change using the same month, not adjacent months.”
• “Compare retail-sales year-on-year change with CPI over matched monthly periods.”
• “Show median-income history, employment by sector, and calculated employment growth.”
• “Show unemployment and resident labour-force participation history.”
• “Find official MAS exchange-rate observations and preserve each published unit.”
• “Show IRAS tax-collection history and calculate category shares only where units match.”
• “Show Singapore merchandise-trade history from SingStat.”

Tourism, population, health, energy, crime, and hawkers

• “Rank visitor-arrival source markets for the latest published period.”
• “Show tourism receipts history and warn me if the curated dataset is stale.”
• “Compare population, live births, deaths, marriages, and divorces over available periods.”
• “Show disease-case history, its last observation, and a clear frozen-data warning if applicable.”
• “Show electricity-generation history and the source agency.”
• “Compare like-for-like recorded-crime series without inferring neighbourhood or individual risk.”
• “Find NEA hawker centres matching Maxwell and profile the published fields.”

Mortgage reference rates

• “Show the latest official SORA and published housing-loan reference-rate series.”
• “Show 24 months of official mortgage reference-rate context and identify the latest period.”
• “At a user-supplied illustrative rate, calculate the monthly payment on a S$600,000 mortgage.”
• “Stress-test that mortgage at 2.5%, 3.5%, and 4.5%, with assumptions shown.”

These are official reference-rate statistics and educational calculations, not live lender offers, credit decisions, or personal financial advice.

Cross-series analysis and discovery

• “Align these quarterly GDP and monthly CPI series to annual periods and explain the aggregation.”
• “Compare two matched series and return observations, Pearson correlation, and calculation notes.”
• “Create a text sparkline and chart-ready points for these observations.”
• “Which Olano tool should answer: ‘How competitive was the latest COE bidding exercise?’”
• “List prompt categories, then show examples for rail and property.”
• “Show the compatibility record for sg_cross_dataset.”

Advanced: multi-step and cross-agency questions

These are where the eight packaged Agent Skills and the analytics tools earn their keep. Each one spans several agencies or several periods, so the answer has to align units, match periods, and keep every source attached. Ask them in a client that has the Agent Skills installed — the Claude Code plugin or the Claude Desktop extension — and Claude will chain the tools itself.

Property and affordability

• “Build a Queenstown property brief: recent 4-room resale medians and quartiles, the nearest MRT stations with walking versus straight-line distance stated, nearby schools and childcare, and an illustrative mortgage at 3.5% on the median price. Show every assumption and source.”
• “Compare HDB resale price per square metre across Tampines, Bedok, and Jurong East over matched months, then test whether the ranking survives switching to a different flat type.”
• “Stress-test a S$600,000 mortgage at 2.5%, 3.5%, and 4.5% against the latest published SORA and housing-loan reference rates, and say plainly which parts are official statistics and which are my own illustrative assumptions.”

Economy and cross-series analysis

• “Align quarterly GDP with monthly CPI to annual periods, explain the aggregation you used, then report the Pearson correlation with its calculation notes and any period you had to drop.”
• “Compare retail sales year-on-year against CPI year-on-year over exactly matched months, and flag any month where the two series use different bases or units.”
• “Track median income, employment by sector, and resident labour-force participation over the longest matched window available, and calculate employment growth per sector.”

Business and sector research

• “Profile the ACRA records matching a company name, resolve the UEN across all 27 shards, make any match uncertainty explicit, then put it in context with formations and cessations for its SSIC sector over matched periods.”
• “Compare net business formations across two SSIC sectors, then check whether the pattern lines up with retail sales and visitor arrivals for the same periods.”

Mobility and location

• “Plan a comparison of three addresses for a new office: resolve each with OneMap, list rail stations within walking distance, show live carpark availability nearby, and summarise the trade-offs without inferring anything the data does not support.”
• “Show the last 12 Category A and Category B COE bidding exercises with premium changes, quota, bids, and bid-to-quota ratio, and say which exercises were most competitive and why.”

Data quality and method

• “Answer using only tools that disclose their source agency and observation period, and list any part of my question you could not answer within that constraint.”
• “Show me which Olano tool you would use for this question and why, before you run it.”
• “Repeat that analysis, but this time show the freshness of every dataset you touched and warn me about any that is stale or frozen.”

Try it on Telegram

The fastest way to see what this server does is to ask it something. @OlanoSGBot is a free Telegram bot, built by Olano and backed by the Singapore MCP tools in this repository. No install, no Node.js, no API key, and no account beyond the Telegram one you already have.

1. Open t.me/OlanoSGBot, or search @OlanoSGBot inside Telegram.
2. Press Start.
3. Ask a question in plain English.

Questions that work well in a chat window:

• “What is the two-hour weather forecast and the latest PSI?”
• “What is the latest Category B COE premium?”
• “Show recent 4-room HDB resale prices in Bedok.”
• “Which MRT stations are nearest to 1 Fullerton Road?”
• “When is the next bus at stop 01012?”

Answers keep their source agency and observation period, the same as they do in an MCP client. The bot remembers your conversation so that follow-up questions work; send /forget whenever you want it to delete the memory and conversation data it holds for you.

The bot is a hosted service rather than a local install. It runs as an Olano-hosted agent on a server in Singapore; each user's conversation and memory is stored separately, scoped to their account on the messaging platform, so no user — and no agent session — can reach another user's data. Composing a reply sends the relevant message content to a third-party language-model provider, which may process it outside Singapore. Read Privacy before sending anything sensitive.

For everyday use, for the complete 291-tool suite, and for the eight Agent Skills, install the server in your own AI client with Quick start. That route runs on your own machine and sends nothing to Olano.

Quick start

New to MCP? An MCP server is a small helper program that your AI app runs on your own computer so it can look things up for you. You install it once, and after that you just ask questions in plain English. This one runs locally and reads official Singapore public data; it has no Olano account, telemetry, or analytics. See Privacy.

Find your app in the table and follow only that section. The default install gives you the complete Olano Singapore suite. You do not need to pick a category, and you do not need an API key.

Just want to see it work first? You do not have to install anything at all — message @OlanoSGBot on Telegram instead. See Try it on Telegram.

Not sure which one you have? If you type questions into a chat window, you are using the Claude Desktop app. If you run claude in a terminal, or you use the Code tab inside the desktop app, you are using Claude Code. Claude Code gets the better install, because it can load the Agent Skills as well as the tools.

Before you start

Installing the Claude Desktop extension? Nothing to install first. Claude Desktop ships its own Node.js runtime and the extension carries everything else. Skip straight to Claude Desktop app.

Every other route runs the server with npx, which comes with Node.js. You need Node.js 20 or newer.

1. Download the LTS installer from nodejs.org and run it.

2. Open a terminal — Terminal on macOS, PowerShell on Windows — and check the version:

   bash

   Copy

   node --version
   

You should see v20. or higher, for example v22.14.0. If you get "command not found" or "not recognized", close the terminal, open a new one, and try again. If it still fails, Node.js did not install correctly.

You do not need to download this repository, clone anything, or run npm install. npx fetches the published package for you the first time it runs.

Claude Desktop app

This section is for the Chat tab of the Claude Desktop app. If you use the Code tab, follow Claude Code instead — you get the eight Agent Skills there too.

Route A — install the extension (recommended)

One file, one click, no terminal and no Node.js.

1. Download the extension.

   ⬇ Download olano-singapore.mcpb

   It is about 2 MB and contains the whole server. Every published version is also listed on the releases page.

2. Install it. Double-click the downloaded file. Claude Desktop opens a review dialog showing what the extension adds. Select Install.

   If double-clicking does nothing, open Claude Desktop and drag the file onto the Settings window, or go to Settings → Extensions → Advanced settings → Install Extension… and pick it.

   Claude Desktop will note that the extension is not signed. That is expected for this project.

3. Leave every setting blank and finish. The four optional boxes are for free government API keys you probably do not have yet. Everything works without them, and you can add them later from Settings → Extensions.

4. Ask a question. No restart needed.

   Show me the latest two-hour weather forecast for Singapore, with timestamps.

That is it, can already. To update later, download the file again and install it over the top.

Route B — let an AI agent set it up for you

Already have Claude Code, Codex, Cursor, or another coding agent that can edit files on your computer? Paste this and it will do the whole job:

Please add the Olano Singapore MCP server to my Claude Desktop configuration.

1. Open my Claude Desktop config file, creating it if it does not exist:
   - macOS:   ~/Library/Application Support/Claude/claude_desktop_config.json
   - Windows: %APPDATA%\Claude\claude_desktop_config.json
   - Linux:   ~/.config/Claude/claude_desktop_config.json
2. Inside the "mcpServers" object, add an entry named "singapore" that runs the
   command "npx" with the arguments ["-y", "@olano/mcp-singapore"]. On Windows use
   the command "cmd" with ["/c", "npx", "-y", "@olano/mcp-singapore"] instead.
3. Keep every server that is already in the file and keep the JSON valid.
4. Do not add any API keys. Show me the final file and tell me to fully quit and
   reopen Claude Desktop.

This route needs Node.js on your computer. Route A does not.

Route C — edit the configuration file yourself

1. Open the settings file. In Claude Desktop, open Settings → Developer → Edit Config. That button opens claude_desktop_config.json in your text editor and creates it if it is missing.

   Can't find that menu? Open the file directly.

   System	File
   macOS	~/Library/Application Support/Claude/claude_desktop_config.json
   Windows	%APPDATA%\Claude\claude_desktop_config.json
   Linux	~/.config/Claude/claude_desktop_config.json

   On macOS the Settings window opens from Claude in the menu bar, not from the chat window. On Windows, check the Claude icon in the system tray. If the file does not exist, create it.

2. Paste the configuration.

   If the file is empty or brand new, paste this entire block — the outer { and } matter:

   config.json

   Copy

   {
     "mcpServers": {
       "singapore": {
         "command": "npx",
         "args": ["-y", "@olano/mcp-singapore"]
       }
     }
   }
   

   If the file already has other servers, keep them and add only the singapore entry, with a comma between entries:

   config.json

   Copy

   {
     "mcpServers": {
       "some-server-you-already-had": {
         "command": "npx",
         "args": ["-y", "some-other-package"]
       },
       "singapore": {
         "command": "npx",
         "args": ["-y", "@olano/mcp-singapore"]
       }
     }
   }
   

   The same file is available at examples/claude-desktop.json.

   On Windows? Use this version instead.

   Windows installs npx as a .cmd script, which some builds of Claude Desktop cannot start directly. If the plain version above shows an error, wrap it in cmd /c:

   config.json

   Copy

   {
     "mcpServers": {
       "singapore": {
         "command": "cmd",
         "args": ["/c", "npx", "-y", "@olano/mcp-singapore"]
       }
     }
   }
   

3. Save the file and fully restart Claude Desktop. Closing the window is not enough. Quit the app completely — Claude → Quit on macOS, or right-click the tray icon and choose Quit on Windows — then open it again.

4. Confirm it worked. Click the + button next to the message box and look under Connectors. You should see singapore listed with its tools. Then ask a question:

   Show me the latest two-hour weather forecast for Singapore, with timestamps.

   The first question may take 20–30 seconds while npx downloads the package. After that it is fast.

If singapore does not appear, see If something is not working. Reference details are in Claude Desktop.

Claude Code

This covers both the claude terminal command and the Code tab in the Claude Desktop app.

Use the plugin. It installs the complete MCP server and all eight Olano Agent Skills, which teach Claude when to reach for which Singapore tool, so answers come back better sourced. It also gives you a safe place to add the optional API keys later.

1. Add the Olano marketplace. Type this at the Claude Code prompt, exactly as shown, including the leading /:

   text

   Copy

   /plugin marketplace add olano-ai/mcp-singapore
   

   This only registers the catalogue. Nothing is installed yet.

2. Install the complete plugin:

   text

   Copy

   /plugin install olano-singapore@olano
   

   Choose User scope when it asks, so the plugin works in every project. If the summary says Run /reload-plugins to activate., run that command too; otherwise the plugin is already live.

3. Confirm and ask a question. Run:

   text

   Copy

   /mcp
   

   You should see singapore connected. Then try:

   List every station on the Thomson-East Coast Line in order and identify the interchanges.

   The first call may take 20–30 seconds while the package downloads. After that it is fast.

Prefer to have Claude do it?

Paste this into Claude Code and it will run the setup and check it for you:

Install the complete Olano Singapore plugin for me. Run
`npx -y @olano/sg-cli setup claude`, verify it with
`npx -y @olano/sg-cli doctor claude`, and tell me when to start a new session.
Do not ask me for optional API keys yet.

Prefer a terminal one-liner?

This does the same two steps without an interactive session, at user scope. It is safe to re-run whenever you want to refresh the Olano marketplace:

npx -y @olano/sg-cli setup claude
npx -y @olano/sg-cli doctor claude

Start a new Claude Code session afterwards, or run /reload-plugins in an open one.

claude mcp add --transport stdio --scope user singapore -- npx -y @olano/mcp-singapore

Codex app

The Codex app and Codex CLI share the same MCP configuration, so you only need to install the server once.

1. Open Settings → MCP servers → Add server.

2. Enter singapore as the name, choose STDIO, use npx as the command, and enter these arguments:

   text

   Copy

   -y @olano/mcp-singapore
   

3. Save, select Restart, and type /mcp in a new conversation to confirm that singapore is connected.

Already installed it with the Codex CLI? Then there is nothing else to add. Restart the app and it will use the same configuration.

Codex CLI

1. Add the complete MCP server:

   bash

   Copy

   codex mcp add singapore -- npx -y @olano/mcp-singapore
   

2. Confirm that it is enabled:

   bash

   Copy

   codex mcp list
   

3. Start a new Codex session and run /mcp, then ask a question.

Prefer to ask Codex to do the installation? Paste this prompt:

Install the complete Olano Singapore MCP for me. Run
`codex mcp add singapore -- npx -y @olano/mcp-singapore`, verify it with
`codex mcp list`, and tell me when to start a new session.
Do not request optional API keys yet.

The command intentionally has no --profile argument. With no profile selected, @olano/mcp-singapore loads the complete suite.

If something is not working

Find the row that matches what you see. The Node.js rows apply only to the npx routes — the Claude Desktop extension has no such dependency.

Check the exact state of a Claude Code install at any time:

npx -y @olano/sg-cli doctor claude

Still stuck? Open an issue with your app name, your operating system, how you installed, and the output of node --version.

Optional: choose a smaller profile

The quick-start commands above install everything. Later, experienced users can choose a focused profile to send fewer tool definitions to the model.

Each profile has its own Claude Code plugin. Install one the same way as the complete plugin:

/plugin install olano-singapore-property@olano

Or select a profile from a terminal, where --profile narrows the MCP server directly:

npx -y @olano/sg-cli setup claude property
codex mcp add singapore-property -- npx -y @olano/mcp-singapore --profile property

For Claude Desktop, add "--profile", "property" to the args array in the config file. The one-click extension always loads the complete suite; use the configuration-file route if you want a profile there.

Questions to try

• “List every station on the Thomson-East Coast Line in order and identify the interchanges.”
• “Find the nearest MRT or LRT stations to latitude 1.29027, longitude 103.851959.”
• “Find the official public ACRA records matching Olano and show the UEN and entity status.”
• “Show the latest two-hour weather forecast and PSI, with timestamps.”
• “Compare Singapore CPI and retail sales over exactly matched monthly periods.”
• “Stress-test a S$600,000 mortgage at 2.5%, 3.5%, and 4.5%, showing every assumption.”

More examples are available in Example questions or from:

npx -y @olano/sg-cli examples

New here? Stop now and try a question. The rest of this README documents packages, transports, credentials, data sources, and development.

More ways to run it

Run without saving MCP configuration

npx -y @olano/mcp-singapore

Add it to a client that accepts the common mcpServers format:

{
  "mcpServers": {
    "singapore": {
      "command": "npx",
      "args": ["-y", "@olano/mcp-singapore"],
      "env": {
        "DATA_GOV_SG_API_KEY": "optional-data-gov-key",
        "ONEMAP_TOKEN": "your-onemap-token",
        "LTA_DATAMALL_API_KEY": "your-lta-account-key",
        "OLANO_SG_CACHE_DIR": "/absolute/path/to/olano-sg-cache"
      }
    }
  }
}

Remove credentials you do not use and never commit real values. The server starts without any credential; only tools that require one will return a missing-credential error.

Smaller server-side tool profiles

The aggregate defaults to all. To reduce the tool definitions sent to a model, select a focused production profile without losing MCP prompts or resources:

npx -y @olano/mcp-singapore --profile mobility
OLANO_SG_PROFILE=property npx -y @olano/mcp-singapore

The stable profiles are mobility, property, business, economy, civic, and finance. singapore_tool_profiles is always available and returns each profile's prefix contract, exact live tool count, and optional tool-name inventory. The same definitions power olano-sg profiles and olano-sg profile <name>. An unknown profile fails at startup instead of silently falling back to all.

MCP over Streamable HTTP

npx -y @olano/mcp-singapore --transport http --host 127.0.0.1 --port 3000

The MCP endpoint is http://127.0.0.1:3000/mcp. Localhost is the default bind address. Add TLS, authentication, request limits, and operational monitoring before exposing it to a network.

Focused servers use the same flags:

npx -y @olano/mcp-rail-sg --transport http --port 3001
npx -y @olano/mcp-weather --transport http --port 3002

CLI

The npm package is @olano/sg-cli; its executable is olano-sg.

npx -y @olano/sg-cli list
npx -y @olano/sg-cli search rail
npx -y @olano/sg-cli examples
npx -y @olano/sg-cli examples property
npx -y @olano/sg-cli ask "Compare recent HDB resale prices in Bedok"
npx -y @olano/sg-cli datasets economy
npx -y @olano/sg-cli prompts
npx -y @olano/sg-cli tool weather_two_hour_forecast '{}'
npx -y @olano/sg-cli setup claude property
npx -y @olano/sg-cli doctor claude property

ask and its query alias use a deterministic local router. They recommend tools, extract obvious arguments, and report missing inputs; they do not send the question to an external model or silently execute the recommendation. Use tool for an explicit invocation.

For client-specific reference, updates, and validation, see Claude Desktop, Claude Code plugins, and Codex and OpenAI plugins.

Prompts and resources

The aggregate server packages reusable MCP prompts:

• research-singapore
• research-neighbourhood
• research-company
• analyze-property
• analyze-mobility

It also exposes read-only resources at singapore://about, singapore://sources, and singapore://examples. Tool-based discovery is available through singapore_prompt_categories, singapore_prompt_examples, singapore_prompt_for_tool, and singapore_ask.

Packaged Agent Skills

The repository includes eight reusable workflows for clients that support Agent Skills:

• research-singapore — general locations, mobility, economy, population, environment, and public services research;
• analyze-singapore-property — HDB/private-property evidence, neighbourhood, transport, amenities, and educational mortgage scenarios;
• research-singapore-business — ACRA/UEN lookup, business formations, sectors, labour, inflation, exchange rates, retail, tourism, and trade context;
• analyze-singapore-mobility — MRT/LRT, bus, road, parking, taxi, routing, and COE analysis;
• analyze-singapore-economy — period- and unit-aware economic indicator analysis;
• research-singapore-civic — weather, health, education, population, safety, and public services;
• analyze-singapore-finance — official rates and transparent mortgage and affordability scenarios; and
• develop-with-singapore-mcp — profile selection, exact tool calls, credentials, transports, and troubleshooting.

See skills/README.md for installation and usage guidance.

Credentials and caching

Every provider uses an in-memory TTL cache. Setting OLANO_SG_CACHE_DIR additionally persists eligible public responses between processes. Cache entries use provider-specific TTLs and hashed keys, are partitioned by a hash of the request-header identity, and omit the entire query string from stored source metadata. Response payloads can still contain addresses, company searches, or other request results. Do not share one cache directory across untrusted tenants; protect it as application data and clear it when retention requirements demand it. singapore_cache_info reports whether it is enabled.

Official upstream sources and attribution

The suite keeps source agency, dataset/table identifier, source URL, retrieval time, observation period, units, and freshness caveats wherever the upstream format allows it.

• data.gov.sg developer guide — Singapore public datasets published by their named agencies, including ACRA, HDB, URA, MOE, ECDA, IRAS, STB, EMA, SPF, MOH, and NEA datasets used by the curated catalog.
• OneMap API documentation — Singapore Land Authority address, geocoding, and routing services.
• LTA DataMall — Land Transport Authority dynamic transport APIs and downloadable rail datasets.
• SingStat Table Builder — Singapore Department of Statistics economic, business, labour, trade, and population tables.
• Meteorological Service Singapore — official weather context; the implemented real-time feeds are retrieved through data.gov.sg.
• Official bank interest rates dataset — SingStat-published series sourced from the Monetary Authority of Singapore, including SORA and published bank interest-rate statistics.
• Singapore Open Data Licence — licence applying to covered data.gov.sg materials.

Rail tools additionally disclose the exact LTA snapshot date and source URL through rail_source_metadata. API availability, data accuracy, rate limits, licences, and upstream terms remain controlled by the respective providers. Applications must comply with those terms and retain required attribution.

Financial-data boundary

Olano integrates only the free official mortgage reference-rate dataset described above. It does not expose live SGX quotes, lender product offers, or insurance premiums because no stable free official API with suitable production and redistribution terms has been verified. It does not scrape comparison sites or label third-party quote data as official Singapore data. Use finance_singapore_data_availability for the current boundary and official reference links.

Safety and engineering

The servers are read-only. Zod validates inputs; upstream origins and paths are fixed in code; requests use timeouts, bounded response sizes, retries, rate spacing, and caching; and tools return explicit errors for missing credentials. Derived tools disclose assumptions and do not turn area, company, crime, property, or finance data into unsupported personal conclusions.

Development

Requires Node.js 20 or newer.

npm install
npm run format:check
npm run lint
npm test
npm run build

Inspect the aggregate server interactively:

npx @modelcontextprotocol/inspector node packages/singapore/dist/cli.js

Build and verify the Claude Desktop bundle. check:mcpb unpacks the packed .mcpb outside the repository and starts it with the exact command its own manifest declares, so a dependency that only resolves through the monorepo fails here rather than on a user's machine:

npm run build:mcpb
npm run check:mcpb
