Capabilities & Tool Schemas (4)Self-reported

Inspect callable tools, capabilities, and parameters exposed to AI agents by Sponsor Finder.

check_sponsor_license

Primary tool. Resolves a company by name (typo-tolerant) and returns a verdict — `licensed`, `formerly_licensed`, `ambiguous`, or `not_found` — with routes, ratings, locations and register dates. Refuses to guess on weak matches.

search_sponsors

Exploratory list search with optional filters. Returns a compact list plus a total count. For one specific company, prefer `check_sponsor_license`.

get_sponsor_details

Full record for one organization by id: routes/ratings/locations/dates (UK) or sponsor type + KvK number (NL). Optionally includes register change history.

get_register_info

Register statistics, data freshness, a terminology glossary, and the legal disclaimer. Use it to explain what a licence, route, rating, or sponsor type means.

Documentation Overview

SponsorFinder MCP Server

An authless, read-only remote MCP server that lets AI assistants (Claude, ChatGPT, Cursor, …) check whether a company holds a UK or Netherlands work-visa sponsorship licence. It proxies the public SponsorFinder API, shaping responses into clean verdicts, and keeps the upstream API key server-side so clients connect with no credentials.

What it does

SponsorFinder tracks two official government registers of licensed work-visa sponsors:

UK — the Home Office register of licensed sponsors, rebuilt from the CSVs the Home Office publishes (checked daily). Carries routes (e.g. Skilled Worker), ratings (A/B) and locations.
Netherlands — the IND public register of recognised sponsors, checked daily. Lists recognised sponsors and their sponsor type (WORK / EXCHANGE / STUDY / RESEARCH); much thinner than the UK data — no routes, ratings, or locations.

This MCP server exposes that data as four tools. It is read-only and authless for clients: the upstream x-api-key is a server-side secret that MCP clients never see. There is no OAuth, no per-user state, and no write tools.

Tools

Tool	Title	What it does	Key inputs
`check_sponsor_license`	Check Sponsorship Licence	Primary tool. Resolves a company by name (typo-tolerant) and returns a verdict — `licensed`, `formerly_licensed`, `ambiguous`, or `not_found` — with routes, ratings, locations and register dates. Refuses to guess on weak matches.	`company_name` (2–100 chars, typos OK), `country` (`uk` \| `nl` \| `both`, default `both`)
`search_sponsors`	Search Sponsor Register	Exploratory list search with optional filters. Returns a compact list plus a total count. For one specific company, prefer `check_sponsor_license`.	`query?`, `country` (`uk` \| `nl`, default `uk`), `city?` (UK), `route?` (UK), `sponsor_type?` (NL: `WORK` \| `EXCHANGE` \| `STUDY` \| `RESEARCH`), `limit` (1–20, default 10)
`get_sponsor_details`	Get Sponsor Details	Full record for one organization by id: routes/ratings/locations/dates (UK) or sponsor type + KvK number (NL). Optionally includes register change history.	`org_id` (int), `country` (`uk` \| `nl`, default `uk`), `include_history` (bool, default `false`)
`get_register_info`	About the Sponsor Registers	Register statistics, data freshness, a terminology glossary, and the legal disclaimer. Use it to explain what a licence, route, rating, or sponsor type means.	none

Every tool is annotated readOnlyHint: true and returns both a human-readable text block and structuredContent, each stamped with the data-freshness date and a source note.

Example prompts

Natural-language things you can ask an assistant once the server is connected:

"Does Google hold a UK sponsorship licence?"
"Is ASML a recognised sponsor in the Netherlands?"
"Search UK Skilled Worker sponsors in Manchester."
"List Dutch WORK-type sponsors matching 'shell'."
"What does a B rating mean?"

A note on name matching. The fuzzy match tolerates typos (e.g. googel uk), but it needs a reasonably complete name to resolve confidently — "Google UK" or "Google UK Limited" resolves cleanly, whereas a single bare word can match many companies. The server deliberately refuses to guess on weak or tied matches: instead of silently picking one, it returns an ambiguous verdict with the candidate list and asks you to disambiguate (or to call get_sponsor_details with the right id). Absence from a register is itself a meaningful answer: it means the company cannot currently sponsor that visa type.

Use it (hosted)

The server is hosted at:

Code

https://mcp.sponsorfinder.io/mcp

Claude Code

Terminal

claude mcp add --transport http sponsorfinder https://mcp.sponsorfinder.io/mcp

claude.ai — Settings → Connectors → Add custom connector → paste the URL above. No authentication is required.

ChatGPT — Settings → Connectors (or a custom GPT's Actions) → Add a custom/remote MCP connector and paste the URL above.

Any MCP client that speaks Streamable HTTP can connect the same way — point it at https://mcp.sponsorfinder.io/mcp.

Run locally

Prerequisites: Node.js 24 and pnpm 11.

bash

pnpm install
cp .env.example .env
# then edit .env and fill in:
#   SPONSORFINDER_API_BASE   e.g. https://api.sponsorfinder.io
#   SPONSORFINDER_API_KEY    your upstream x-api-key (server-side secret)

Run one of the two transports in watch mode:

bash

pnpm dev:stdio   # stdio transport (Claude Desktop / Claude Code / MCP Inspector)
pnpm dev:http    # Streamable HTTP on http://localhost:3001/mcp

Add the local stdio build to Claude Code:

bash

pnpm build
claude mcp add sponsorfinder -- node dist/entry/stdio.js

Inspect the tools interactively with the MCP Inspector against either transport:

Terminal

npx @modelcontextprotocol/inspector

Configuration

All configuration is via environment variables (see .env.example):

Name	Required	Default	Description
`SPONSORFINDER_API_BASE`	yes	—	Base URL of the upstream SponsorFinder API, no trailing slash (e.g. `https://api.sponsorfinder.io`).
`SPONSORFINDER_API_KEY`	yes	—	Upstream `x-api-key` header value. Server-side secret — never exposed to MCP clients, tool output, errors, or logs.
`PORT`	no	`3001`	HTTP port for the Node entry (`src/entry/node.ts`). Ignored by stdio and Cloudflare Workers.
`UPSTREAM_TIMEOUT_MS`	no	`10000`	Upstream request timeout in milliseconds (aborted via `AbortSignal.timeout()`).

SPONSORFINDER_API_KEY is the one true secret. MCP clients connect authless; the key lives only on the server (a Docker env var or a Cloudflare Workers secret) and is never surfaced to clients.

Self-host / deploy

The Web-standard core runs on both Node and Cloudflare Workers; only the entry file differs.

Docker (primary) — image ghcr.io/alirezahamid/sponsor-finder-mcp, config in Dockerfile and docker-compose.yml:

Terminal

docker compose up -d

Put a reverse proxy (Caddy/nginx) in front of mcp.sponsorfinder.io and pass POST, GET and DELETE through to /mcp. Streamable HTTP needs response buffering off (proxy_buffering off; in nginx; Caddy's defaults are fine).

Cloudflare Workers — config in wrangler.jsonc:

Terminal

wrangler secret put SPONSORFINDER_API_KEY
pnpm deploy:worker

Development

Script	What it does
`pnpm typecheck`	Type-check with `tsc --noEmit`.
`pnpm lint`	Lint with ESLint.
`pnpm test`	Run unit tests (excludes smoke tests).
`pnpm test:smoke`	Integration smoke tests against the real staging API (needs secrets).
`pnpm build`	Bundle to `dist/` with tsup.
`pnpm check`	`typecheck` + `lint` + `test` in one go.
