Uses `npx` (confidence: high): ```json "mcpServers": { "obsidiancorps-umami-analytics": { "command": "npx", "args": ["-y","@obsidiancorps/umami-mcp"] } } ``` ## Documentation & README # ObsidianCorps Umami MCP **Ask questions about your self-hosted Umami analytics without sending the data to another analytics SaaS.** A secure, model-friendly [Model Context Protocol](https://modelcontextprotocol.io/) server for Umami Cloud and self-hosted [Umami Analytics](https://umami.is/). It targets **Umami v3.3.1** and the **2026-07-28 MCP protocol**, while retaining compatibility with 2025-era MCP clients. ![Umami MCP answering three analytics questions](https://raw.githubusercontent.com/ObsidianCorps/umami-mcp/main/docs/assets/umami-mcp-demo.gif) ## Install Requirements: Node.js 20 or newer and one configured [authentication mode](#authentication). ```bash npx -y @obsidiancorps/umami-mcp ``` Try asking: - “Compare website traffic with last month.” - “Which sources generated the most conversions?” - “Find pages with poor Web Vitals.” ## Why this implementation - Current Umami v3 coverage: revenue APIs, session replay, heatmaps, event/session property pivots and typed series, segments, cohorts, boards, links, pixels, Web Vitals reports, and the established analytics APIs. - Compact model surface: 17 read tools organize the API around analytical workflows instead of advertising dozens of near-duplicate endpoint tools. - Model-friendly inputs: website names/domains resolve automatically, one accessible website is selected automatically, and date ranges accept presets or exact ISO/epoch timestamps. - Structured MCP results: every tool advertises an output schema and returns `structuredContent` plus readable JSON. - Safe defaults: mutations are absent by default; destructive tools need a second opt-in and an exact target-specific confirmation string. - Two modern transports: local stdio and stateless Streamable HTTP. Legacy HTTP+SSE is intentionally not carried forward. - Defense in depth: response byte limits, request timeouts, HTTPS enforcement, token refresh, DNS-rebinding protection, exact origin checks, and constant-time MCP bearer checks. - Cloud and self-hosted auth: Umami Cloud API keys, pre-issued self-hosted tokens, or lazy username/password login—including Umami v3.3+ two-factor verification—with a single refresh after `401`. ## Configure ### From source Requirements: Node.js 20 or newer. ```bash npm install npm run build UMAMI_API_KEY=your-key node dist/cli.js ``` Example MCP client configuration: ```json { "mcpServers": { "umami": { "command": "npx", "args": ["-y", "@obsidiancorps/umami-mcp"], "env": { "UMAMI_API_KEY": "your-key", "UMAMI_DEFAULT_WEBSITE_ID": "optional-website-uuid" } } } } ``` For a source checkout, replace the command with `node` and the arguments with the absolute path to `dist/cli.js`. ## Authentication Choose exactly one mode: | Mode | Variables | API base | | --------------------- | ---------------------------------------------------------------- | ------------------------------------- | | Umami Cloud | `UMAMI_API_KEY` | Defaults to `https://api.umami.is/v1` | | Self-hosted token | `UMAMI_BASE_URL`, `UMAMI_TOKEN` | `/api` is added to a root URL | | Self-hosted login | `UMAMI_BASE_URL`, `UMAMI_USERNAME`, `UMAMI_PASSWORD` | `/api` is added to a root URL | | Self-hosted login+2FA | Login variables plus `UMAMI_TWO_FACTOR_SECRET` | `/api` is added to a root URL | | One-off 2FA login | Login variables plus a current six-digit `UMAMI_TWO_FACTOR_CODE` | `/api` is added to a root URL | `UMAMI_TWO_FACTOR_SECRET` is the Base32 setup seed shown when enrolling an authenticator. The MCP generates a six-digit SHA-1 TOTP just-in-time and never logs or returns it. Because storing the password and TOTP seed together removes the separation between factors, use a dedicated least-privilege Umami account and protect its environment. A pre-issued `UMAMI_TOKEN` avoids retaining either credential. `UMAMI_TWO_FACTOR_CODE` is only a one-off fallback; it expires quickly and is unsuitable for normal MCP startup. Configure only one two-factor variable. Non-local plain HTTP Umami URLs are rejected. For an explicitly trusted private network only, set `UMAMI_ALLOW_INSECURE_HTTP=true`. ## Tools The default read-only set is: | Tool | Purpose | | ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------ | | `umami_check_connection` | Verify auth and inspect the current account | | `umami_list_websites`, `umami_get_website` | Discover and inspect sites | | `umami_get_overview`, `umami_get_metrics` | Aggregate KPIs, series, and ranked dimensions | | `umami_get_realtime` | Inspect the current 30-minute activity window | | `umami_list_sessions`, `umami_inspect_session` | Browse sessions, activity, properties, and replay metadata | | `umami_query_session_data` | Query session properties, pivots, stats, weekly traffic, and typed series | | `umami_list_events`, `umami_query_event_data` | Browse events, comparison stats, series, properties, values, and pivots | | `umami_get_revenue` | Fetch revenue stats, charts, dimensions, and sessions | | `umami_list_replays` | List replays or retrieve a replay event stream | | `umami_run_report`, `umami_list_reports` | Run or discover funnel, journey, goal, retention, attribution, UTM, revenue, performance, breakdown, and heatmap reports | | `umami_list_segments` | Discover segments and cohorts | | `umami_list_assets` | Discover boards, tracked links, and pixels | Resources expose `umami://capabilities` and the live `umami://websites` list. Reusable prompts cover analytics review, conversion review, and realtime triage. ### Time ranges Most analytical tools accept either: - `period`: `last_24_hours`, `last_7_days`, `last_30_days`, `last_90_days`, `today`, `yesterday`, `this_week`, `last_week`, `this_month`, or `last_month`; or - both `startAt` and `endAt` as epoch milliseconds or ISO 8601 timestamps with an offset. Calendar periods honor the supplied IANA `timezone`. Rolling periods retain the most recent data instead of rounding to midnight. ## Mutations and destructive operations No mutation tool is registered by default. ```bash UMAMI_ENABLE_WRITE_TOOLS=true ``` This adds tools for creating/updating websites, segments, reports, boards/links/pixels, and sending analytics events. To additionally expose permanent reset/delete operations: ```bash UMAMI_ENABLE_WRITE_TOOLS=true UMAMI_ENABLE_DESTRUCTIVE_TOOLS=true ``` Destructive calls require confirmation strings such as `RESET ` or `DELETE reports `. MCP annotations also identify these tools as destructive so supporting hosts can require approval. ## Streamable HTTP Loopback example: ```bash MCP_TRANSPORT=http MCP_BEARER_TOKEN=replace-me npm start # MCP: http://127.0.0.1:3000/mcp # Health: http://127.0.0.1:3000/health ``` For a container or non-loopback bind, both `MCP_BEARER_TOKEN` and `MCP_ALLOWED_HOSTS` are required: ```bash docker build -t umami-mcp . docker run --rm -p 3000:3000 \ -e UMAMI_API_KEY=your-key \ -e MCP_BEARER_TOKEN=long-random-secret \ -e MCP_ALLOWED_HOSTS=mcp.example.com \ umami-mcp ``` Set `MCP_ALLOWED_ORIGINS` to a comma-separated list of exact browser origins if browser-based MCP clients connect. Requests without an `Origin` header remain valid for native clients. Terminate TLS at a trusted reverse proxy; the built-in static bearer gate is suitable behind that boundary, not a replacement for OAuth on a public multi-user service. ## Configuration reference | Variable | Default | Description | | -------------------------------- | -------------------------- | -------------------------------------------------- | | `UMAMI_BASE_URL` | Cloud API for API-key auth | Umami root or full API base URL | | `UMAMI_DEFAULT_WEBSITE_ID` | — | Avoids site resolution for most calls | | `UMAMI_TIMEOUT_MS` | `15000` | Upstream request timeout, 100–120000 ms | | `UMAMI_MAX_RESPONSE_BYTES` | `512000` | Maximum upstream response, 1 KB–10 MB | | `UMAMI_ENABLE_WRITE_TOOLS` | `false` | Registers non-destructive mutation tools | | `UMAMI_ENABLE_DESTRUCTIVE_TOOLS` | `false` | Registers reset/delete tools; requires write tools | | `MCP_TRANSPORT` | `stdio` | `stdio`, `http`, or `streamable-http` | | `MCP_HOST` | `127.0.0.1` | HTTP bind address | | `MCP_PORT` | `3000` | HTTP port | | `MCP_BEARER_TOKEN` | — | Protects the HTTP MCP endpoint | | `MCP_ALLOWED_HOSTS` | — | Comma-separated hostnames for non-loopback HTTP | | `MCP_ALLOWED_ORIGINS` | — | Comma-separated exact browser origins | ## Development ```bash npm install npm test npm run typecheck npm run lint npm run format:check npm run build npm run check ``` Tests drive the server through real in-memory, stdio, and Streamable HTTP MCP clients.
