Quote the reason, not just the number. - **Never more than 24 hours stale, and it says so.** Every response carries `cached` and `fetched_at`. OpenCorporates' own knowledge base tells users to ["allow 30 days"](https://knowledge.opencorporates.com/knowledge-base/the-data-on-opencorporates-is-out-of-date/) for a correction to reach its site — a 30× freshness gap, stated by the incumbent about itself. - **Seven tools, not fifty** — five registry tools plus two ChatGPT connector aliases. Tool-selection accuracy [degrades past 30-50 tools loaded into an agent's context](https://code.claude.com/docs/en/agent-sdk/tool-search), and some clients cap around 40. Seven tools is roughly 17% of that budget, next to competitors in this space shipping 23 to 78 tools for the same job. **Security.** Read-only, always — nothing here writes to a register or anywhere else. No credentials are required from a caller; this deployment's own upstream credential (`COMPANIES_HOUSE_API_KEY`) is read from the environment and never logged or returned. Three named upstreams, and nothing else is ever called: `data.brreg.no`, `api.company-information.service.gov.uk` and `gw.api.bolagsverket.se`. No personal data beyond what each national register already publishes about the entity itself — and because a Swedish sole trader's company number *is* their personnummer, the usage log stores no identifier at all for a country whose identifiers can be a natural person's ([`legal/privacy.md`](https://github.com/foretak/registry-mcp/blob/HEAD/legal/privacy.md)). This service does not perform sanctions, PEP or adverse-media screening, and it does not verify bank account details.

In ChatGPT, open **Settings → Connectors**, add a custom connector, and give it: https://api.foretak.dev/mcp No authentication, no key, no account. If your ChatGPT plan does not show custom connectors under Settings → Connectors, turn on **Settings → Security and login → Developer mode** first, then add the URL from . `search` takes one free-text query — a company name, a national identifier, or a name plus a country ("Tesco United Kingdom") — and returns citable rows; `fetch` takes a row's `id` (`"NO:923609016"`) and returns that company's register record **and its statutory filing deadlines**, with the full JSON of both in `metadata`. ## Add to Claude Desktop Claude Desktop takes the same URL as a custom connector: **Settings → Connectors → Add custom connector**, then `https://api.foretak.dev/mcp`. No key. For a local stdio install instead, see [Configuration](#configuration). > Status: `0.3.0`, live — `GET /health` returns `{"version":"0.3.0","countries":["GB","NO","SE"]}`. The five registry tools and their response shapes are frozen; two connector aliases (`search`, `fetch`) wrap them for ChatGPT and add no new shape. The hosted API at `api.foretak.dev` is live, and listed in the official MCP registry as `io.github.foretak/registry-mcp`. Countries: United Kingdom (Companies House), Norway (brreg), Sweden (Bolagsverket) — see [below](#tools) for each country's identifier format and example calls. ## Add to Claude Code The same two commands as above — Streamable HTTP or local stdio. To add it as a project-level `.mcp.json` file instead of the CLI, see [Configuration](#configuration). ## What it returns ```console $ curl https://api.foretak.dev/v1/NO/company/923609016 { "country": "NO", "registry": "brreg", "id": "923609016", "id_formatted": "923 609 016", "id_scheme": "organisasjonsnummer", "euid": null, "name": "EQUINOR ASA", "legal_form_code": "ASA", "legal_form": "Public limited company", "legal_form_local": "Allmennaksjeselskap", "status": "active", "is_active": true, "registered_at": "1995-03-12", "vat_registered": true, "vat_number": "NO923609016MVA", "vat_registered_at": "1989-07-01", "employees": 21239, "share_capital": 5976872600.0, "share_capital_currency": "NOK", "business_address": {"lines": ["Forusbeen 50"], "postal_code": "4035", "city": "STAVANGER"}, "advertising_protected": null, "source": "Enhetsregisteret (Brønnøysundregistrene)", "license": "NLOD 2.0" } ``` Abridged — the full `CompanyReport` also carries `previous_names`, `industry_codes`, `registers`, `purpose`, `parent_id`, `confidence`, `cached`, `fetched_at` and `notes`. Every field is documented in [`llms-full.txt`](https://github.com/foretak/registry-mcp/blob/HEAD/static/llms-full.txt) §5. `euid` is the EU-wide identifier some member-state registers publish (Finland does; none of ours do yet) — never the LEI, never constructed from parts. `advertising_protected` is `true`/`false`/`null`: whether the register marks this entity as protected against direct-marketing use, `null` meaning the register publishes no such flag at all (Norway and the UK, today); where it is `true` (Sweden's *reklamspärr*, for one), a `notes` sentence states it and that marking must travel with any contact details you pass on. The United Kingdom, same shape, same abridgement: ```console $ curl https://api.foretak.dev/v1/GB/company/00445790 { "country": "GB", "registry": "companies-house", "id": "00445790", "id_formatted": null, "id_scheme": "company number", "euid": null, "name": "TESCO PLC", "legal_form_code": "plc", "legal_form": "Public limited company", "status": "active", "is_active": true, "registered_at": "1947-11-27", "vat_registered": null, "vat_number": null, "employees": null, "employees_reported": false, "registers": {"charges": false, "insolvency": false}, "industry_codes": [{"code": "47110", "description": null, "scheme": "SIC 2007", "rank": 1}], "business_address": {"lines": ["Tesco House, Shire Park", "Kestrel Way"], "postal_code": "AL7 1GA", "city": "Welwyn Garden City"}, "advertising_protected": null, "published_deadlines": [ {"kind": "annual_accounts", "due_date": "2027-08-26", "period_end": "2027-02-26", "overdue": false, "source": "accounts.next_accounts.due_on"}, {"kind": "confirmation_statement", "due_date": "2027-07-02", "period_end": "2027-06-18", "overdue": false, "source": "confirmation_statement.next_due"} ], "source": "Companies House (UK)", "license": "Crown copyright — Companies House public register, free to re-use" } ``` `published_deadlines` carries the dates the register publishes itself, with the upstream field each came from. It is `[]` for Norway and Sweden, which compute all of their own. Sweden, added in 0.3.0, is where "one shape" starts to earn the claim: ```console $ curl https://api.foretak.dev/v1/SE/company/5560160680 { "country": "SE", "registry": "bolagsverket", "id": "5560160680", "id_formatted": "556016-0680", "id_scheme": "organisationsnummer", "euid": null, "name": "Telefonaktiebolaget LM Ericsson", "legal_form_code": "AB", "legal_form": "Private or public limited company", "legal_form_local": "Aktiebolag", "status": "active", "is_active": true, "registered_at": "1918-08-19", "vat_registered": null, "vat_number": null, "employees": null, "employees_reported": false, "industry_codes": [{"code": "70100", "description": "Verksamheter som utövas av huvudkontor", "scheme": "SNI 2007", "rank": 1}], "postal_address": {"postal_code": "16483", "city": "STOCKHOLM", "country_code": "SE"}, "advertising_protected": null, "published_deadlines": [], "source": "Bolagsverket (bolagsverket.se)", "license": "Free re-use (Bolagsverket/SCB high-value datasets, EU Open Data Directive) — the publisher names no licence" } ``` Bolagsverket names no licence for this data, so neither do we: the string says what the permission is and says plainly that there is no licence name to quote, because a familiar name in that field would be a fabrication. Sweden publishes no status field at all. `status` is derived from three independent signals — a strike-off date, an ongoing winding-up or restructuring procedure, and Statistics Sweden's "economically active" flag — and `is_active` therefore means *on the register and not winding down*, which is not the same as trading. Where any of that is unavailable the answer is `unknown`, never `active`. Two dates are computed, and each carries the provision it comes from: ```console $ curl "https://api.foretak.dev/v1/SE/company/5560160680/deadlines?today=2026-09-07" {"kind": "general_meeting", "due_date": "2027-06-30", "days_until": 296, "rolled_forward": false, "period_label": "2026"} {"kind": "annual_accounts", "due_date": "2027-07-31", "days_until": 327, "rolled_forward": false, "period_label": "2026"} ``` Six months to the annual general meeting (aktiebolagslagen 7 kap. 10 §) and seven to the filing before a late fee bites (årsredovisningslagen 8 kap. 6 §). Neither date is rolled forward off a weekend, because no Swedish source says it moves. Both assume a financial year ending 31 December, which the free dataset does not publish — and a `notes` sentence says exactly that, including how to shift both dates if the year end is different. `search_company` answers `not_implemented` for Sweden: the free API has four operations and none of them accepts a name. Note the `null`s. Companies House publishes no VAT status, no employee count and no share capital for any company, so those fields are `null` rather than guessed — `null` means "this register does not say", never "no". That honesty is the point of one shape across countries. And the deadlines, which is where the UK module earns its keep: ```console $ curl "https://api.foretak.dev/v1/GB/company/00445790/deadlines?today=2026-09-04" { "company_name": "TESCO PLC", "today": "2026-09-04", "deadlines": [ {"kind": "confirmation_statement", "local_name": "Confirmation statement (CS01)", "due_date": "2027-07-02", "period_end": "2027-06-18", "days_until": 301, "applies_because": "Companies House publishes this date for the company itself; it is the register's own figure, not a calculation."}, {"kind": "annual_accounts", "local_name": "Annual accounts", "due_date": "2027-08-26", "period_end": "2027-02-26", "days_until": 356, "applies_because": "Companies House publishes this date for the company itself; it is the register's own figure, not a calculation."} ] } ``` Where Companies House publishes a date, it is quoted; where it does not, the date is computed from a cited statute and `applies_because` says so. UK deadlines never roll forward off a weekend or bank holiday, and `days_until` goes negative for a filing the register still shows as overdue. **Running it yourself?** The hosted service at `api.foretak.dev` has every credential configured. A self-hosted copy needs a free [Companies House key](https://developer.company-information.service.gov.uk/get-started) for `GB` and an OAuth 2 client pair from Bolagsverket (`BOLAGSVERKET_CLIENT_ID`, `BOLAGSVERKET_CLIENT_SECRET`) for `SE`; without them those two countries return `upstream_error` naming the variable, and every other country keeps answering. Norway needs nothing. ## Tools | Tool | What it does | |---|---| | `lookup_company(id, country="NO")` | Full `CompanyReport` for one company by national identifier | | `search_company(name, country="NO", limit=10)` | `SearchResult` — candidates with identifiers, in the register's relevance order, each scored | | `company_deadlines(id, country="NO", today=None)` | `DeadlineReport` — the next occurrence of each statutory filing obligation | | `validate_company_id(id, country="NO")` | `ValidationResult` — validate and normalise an identifier with no network call | | `list_countries()` | Which national registries are supported right now | **Connector aliases** — for ChatGPT, which reaches an MCP server through exactly `search` and `fetch` ([Add to ChatGPT](#add-to-chatgpt)); add no new response shape and have no REST twin. | Tool | What it does | |---|---| | `search(query)` | ChatGPT connector alias for `search_company` — one free-text query, `{"results": [{"id", "title", "url"}]}` | | `fetch(id)` | ChatGPT connector alias for `lookup_company` + `company_deadlines` — one `"{COUNTRY}:{identifier}"`, a Markdown document with both reports in `metadata` | Plus the resource `registry://rules/{country}` (identifier rules, legal forms, deadline rules — read once instead of validating in a loop) and the prompt `explain_company`. `parent_id` and `in_group` on a Norwegian `CompanyReport` describe Enhetsregisteret's own parent/sub-unit relation for that entity — nothing more. There is no group-walk tool: following a corporate group upward means calling `lookup_company` again on `parent_id`, repeatedly, and that walk answers "what does the register list as this entity's parent?", not "who beneficially owns or controls this company?" — a different question this service does not answer. See [`llms-full.txt`](https://github.com/foretak/registry-mcp/blob/HEAD/static/llms-full.txt) §5. ## Why an agent checks a company Three rules make this a duty rather than a nicety. Finanstilsynet's [Rundskriv 15/2019](https://www.finanstilsynet.no/nyhetsarkiv/rundskriv/2019/veiledning-om-regnskapsforeres-og-regnskapsforerselskapers-etterlevelse-av-hvitvaskingsregelverket/) § 4.4.1 accepts an *oppslag* against Enhetsregisteret no older than three months, one month where the check rests on company details the customer supplied, and asks for *notoritet* about the lookup: what was consulted, and when. From [1 January 2027](https://www.regjeringen.no/no/aktuelt/nye-lovregler-om-e-fakturering-i-naringslivet-og-enkelte-andre-lovendringer-pa-finansmarkedsomradet-settes-i-kraft/) Norwegian bookkeeping-obliged businesses must invoice each other by e-invoice, and the receiver is resolved in ELMA as [`0192:` plus organisasjonsnummer](https://www.anskaffelser.no/verktoy/veiledere/mottakere-av-ehf-og-peppol-bis), the identifier these tools already take. From 10 July 2027, [AMLR](https://eur-lex.europa.eu/eli/reg/2024/1624/oj/eng) Article 23(4) requires "valid proof of registration or a recently issued excerpt of the register" for every new business relationship with a legal entity. That is what `source_url`, `fetched_at`, `cached`, `license` and `applies_because` are for: which record was consulted, when it was read, whether it came from the 24 h cache, the terms it travels under, and whether a deadline was quoted from the register or computed from a named rule. The limits, stated rather than implied: no sanctions or PEP screening; no bank-account verification, and the commonest invoice fraud is payment redirection, where the supplier is real and only the account number is wrong; and no beneficial owners, which brreg [releases on application only](https://www.brreg.no/bruke-data-fra-bronnoysundregistrene/datasett-og-api/data-om-reelle-rettighetshavere/), to categories of applicant that do not include a product vendor. Fuller version in [`llms-full.txt`](https://github.com/foretak/registry-mcp/blob/HEAD/static/llms-full.txt) §9. ## Configuration
Claude Code — .mcp.json in the project root ```json { "mcpServers": { "registry-mcp": { "command": "uvx", "args": ["registry-mcp"], "env": { "REGISTRY_MCP_CONTACT_EMAIL": "you@example.com", "COMPANIES_HOUSE_API_KEY": "your-companies-house-key" } } } } ``` Drop `COMPANIES_HOUSE_API_KEY` if you only need Norway; every other country works without it.
Cursor — ~/.cursor/mcp.json (or .cursor/mcp.json in the project) ```json { "mcpServers": { "registry-mcp": { "command": "uvx", "args": ["registry-mcp"], "env": { "REGISTRY_MCP_CONTACT_EMAIL": "you@example.com" } } } } ```
Claude Desktop — claude_desktop_config.json macOS: `~/Library/Application Support/Claude/claude_desktop_config.json` Windows: `%APPDATA%\Claude\claude_desktop_config.json` ```json { "mcpServers": { "registry-mcp": { "command": "uvx", "args": ["registry-mcp"], "env": { "REGISTRY_MCP_CONTACT_EMAIL": "you@example.com" } } } } ```
npm instead of uvx — same server, Node launcher ```json { "mcpServers": { "registry-mcp": { "command": "npx", "args": ["-y", "registry-mcp"] } } } ``` `npx registry-mcp` shells out to `uvx registry-mcp` (falling back to `pipx run registry-mcp`), so Python 3.12+ and one of `uv` or `pipx` must be present.
Hosted, no local install — Streamable HTTP ```json { "mcpServers": { "registry-mcp": { "type": "http", "url": "https://api.foretak.dev/mcp" } } } ```
**Environment variables** — all optional: | Variable | Meaning | |---|---| | `REGISTRY_MCP_CONTACT_EMAIL` | Contact address sent in the `User-Agent` to the national registry, as Brønnøysundregistrene asks of API clients. Unset means an anonymous client, which may be throttled or blocked upstream. | | `REGISTRY_MCP_CACHE_PATH` | Path to the local SQLite response cache (24 h TTL). Defaults to `./data/cache.sqlite3`. | | `COMPANIES_HOUSE_API_KEY` | Required for the United Kingdom (`GB`). A key is [free and instant](https://developer.company-information.service.gov.uk/get-started). Unset means `GB` lookups return `upstream_error` with a hint naming this variable — every other country keeps working. | | `BOLAGSVERKET_CLIENT_ID`, `BOLAGSVERKET_CLIENT_SECRET` | Required for Sweden (`SE`). An OAuth 2 client pair Bolagsverket issues on request; the data itself is free under the EU high-value-datasets regulation. Unset means `SE` lookups return `upstream_error` naming both variables — every other country keeps working. | ## REST Every tool has a REST twin returning the identical JSON document. ```bash # One company by organisasjonsnummer curl https://api.foretak.dev/v1/NO/company/923609016 # Search by name curl "https://api.foretak.dev/v1/NO/search?q=equinor&limit=5" # Statutory filing deadlines, from a date you choose curl "https://api.foretak.dev/v1/NO/company/923609016/deadlines?today=2026-01-15" # Checksum-validate an identifier — no upstream call, instant curl https://api.foretak.dev/v1/NO/validate/923609016 # Which countries are live, and which need an API key curl https://api.foretak.dev/v1/countries # The same five routes for the United Kingdom — GB, never UK curl https://api.foretak.dev/v1/GB/company/00445790 curl "https://api.foretak.dev/v1/GB/search?q=tesco&limit=5" curl "https://api.foretak.dev/v1/GB/company/00445790/deadlines?today=2026-09-04" curl https://api.foretak.dev/v1/GB/validate/445790 # Sweden — four of the five. /search returns 501 not_implemented: the free # Bolagsverket API has no name index, and the error's hint says so. curl https://api.foretak.dev/v1/SE/company/5560160680 curl "https://api.foretak.dev/v1/SE/company/5560160680/deadlines?today=2026-09-07" curl https://api.foretak.dev/v1/SE/validate/556016-0680 ``` Machine-readable docs: [`/llms.txt`](https://api.foretak.dev/llms.txt), [`/llms-full.txt`](https://api.foretak.dev/llms-full.txt), [`/openapi.json`](https://api.foretak.dev/openapi.json). ## Adding your country Norway is one folder. So is the United Kingdom: [`registries/gb/`](https://github.com/foretak/registry-mcp/blob/HEAD/src/registry_mcp/registries/gb/) was added as four files and one import line, and `GB` appeared in `list_countries`, in every tool, in `/openapi.json` and in `registry://rules/GB` on its own. So is Sweden — [`registries/se/`](https://github.com/foretak/registry-mcp/blob/HEAD/src/registry_mcp/registries/se/) shipped in 0.3.0 with **no change to `core/`**, including the parts of Sweden that fit the abstraction worst: a register that publishes no status field, an operation the upstream does not offer (`search_company` answers `not_implemented`), and an identifier that can be a natural person's national ID. Copy `src/registry_mcp/registries/xx/` to `registries//`, implement four methods, add one import line — nothing in `core/` changes, and both surfaces plus the manifests light up for the new country automatically. **→ [CONTRIBUTING.md](https://github.com/foretak/registry-mcp/blob/HEAD/CONTRIBUTING.md) — "Add your country"**, and the [`new country` issue template](https://github.com/foretak/registry-mcp/blob/HEAD/.github/ISSUE_TEMPLATE/new_country.yml) to claim one first. ## Development ```bash uv sync --all-extras uv run pytest # `-m "not live"` to skip the tests that hit the real registry uv run mypy . uv run ruff check . ``` Layout: ``` src/registry_mcp/core/ country-neutral models, Registry ABC, rules, date helpers src/registry_mcp/registries/ one folder per country — no/ (Norway), gb/ (UK), se/ (Sweden), xx/ (template) src/registry_mcp/api/ FastAPI REST surface src/registry_mcp/mcp/ FastMCP server (stdio + Streamable HTTP at /mcp) ``` ## Documents - [`NORBIZ_SPEC.md`](https://github.com/foretak/registry-mcp/blob/HEAD/NORBIZ_SPEC.md) — technical spec of the Norwegian module - [`UK_SPEC.md`](https://github.com/foretak/registry-mcp/blob/HEAD/UK_SPEC.md) — technical spec of the UK module - [`SWEDEN_SPEC.md`](https://github.com/foretak/registry-mcp/blob/HEAD/SWEDEN_SPEC.md) — technical spec of the Swedish module - [`DECISIONS.md`](https://github.com/foretak/registry-mcp/blob/HEAD/DECISIONS.md) — interface and schema decisions - [`KEYWORDS.md`](https://github.com/foretak/registry-mcp/blob/HEAD/KEYWORDS.md) — the canonical alias list - [`SUBMISSIONS.md`](https://github.com/foretak/registry-mcp/blob/HEAD/SUBMISSIONS.md) — registry submission status - [`legal/terms.md`](https://github.com/foretak/registry-mcp/blob/HEAD/legal/terms.md) — terms of use and data attribution ## Data source and licence Norwegian data comes from **Enhetsregisteret (Brønnøysundregistrene)**, published under **NLOD 2.0** — attribution required. UK data comes from the **Companies House public register**, Crown copyright, free to re-use with no attribution condition; we cite it anyway. Swedish data comes from **Bolagsverket**, with Statistics Sweden (**SCB**) as a second producer inside the same payload, free to re-use as a *värdefull datamängd* under the EU high-value-datasets regime — Bolagsverket's own words are *"Det krävs inget avtal för att du ska få använda vårt API för värdefulla datamängder"* and *"Värdefulla datamängder är avgiftsfritt"* — and **Bolagsverket names no licence**, so neither do we: the `license` string states the permission and states plainly that there is no licence name to quote. Every response carries `source`, `source_url` and `license` so the attribution travels with the data. This project's own code is MIT licensed.
