MCP

Use Unclaimed inside Claude, ChatGPT or Cursor

Unclaimed runs a free, public MCP server — no key, no install, no rate limit — over the same sourced dataset the site is built from: government and institutional benefits for households, and grants for companies. Point any MCP-capable chatbot or editor at the URL below and it can ask this data directly, instead of guessing from what it already knows.

Server URL

https://unclaimedgrant.com/mcp

Connect from Claude

In Claude, open Customize → Connectors (custom connectors are available on Free, Pro, Max, Team and Enterprise plans; on Team or Enterprise an Owner first adds it under Organization settings → Connectors, then members click "Connect" on it).
Click the "+" button next to Connectors, then "Add custom connector".
Paste https://unclaimedgrant.com/mcp as the remote MCP server URL.
Click "Add". You can now enable it per-conversation from the "+" button on the chat composer, under "Connectors".

Verified against Claude's own help article, linked in Sources below — steps change as the product does, so treat that article as the source of truth over this page if they ever disagree.

Connect from ChatGPT

Turn on developer mode: Settings → Apps → Advanced settings → Developer mode. OpenAI's article describes this for Pro (read/fetch tools only — which is all Unclaimed has) and for Business, Enterprise and Edu workspaces, where an admin may need to allow it first.
Go to Settings → Apps → Create, and enter https://unclaimedgrant.com/mcp as the endpoint.
Click "Scan Tools", wait for it to finish, then click "Create".
In a chat, select the app for your message, or mention it in your prompt.

Verified against OpenAI's own help article, linked in Sources below. OpenAI's article notes that write/modify MCP actions are in beta for Business/Enterprise/Edu only — every Unclaimed tool is read-only, so this does not affect using it.

Connect from Claude Code, Cursor, or any JSON-config MCP client

In Claude Code, one command:

claude mcp add --transport http unclaimed https://unclaimedgrant.com/mcp

In Cursor or another client that reads a JSON config, add this to its MCP config file:

{
  "mcpServers": {
    "unclaimed": { "url": "https://unclaimedgrant.com/mcp" }
  }
}

`get_procedure`	Return how to apply for one programme: ordered steps, application channel and URL, deadline type and note, and whether the benefit is paid automatically.
`get_coverage`	Return dataset coverage: countries, programme counts, human-verified counts, categories, regions and income bands.

Example prompts

"I live in France, I'm a student paying rent — what am I missing?"
"We're a UK seed-stage SaaS company with 8 employees doing R&D — search company grants for us."
"What documents do I need for [a programme you name]?"
"Which programmes in Germany close in the next month?"

Honest limits

Free-tier answers over MCP match the free web check exactly: check_entitlements and check_company_eligibility return totals and counts, not the named list, unless the call carries an entitled session. search_programmes and search_company_grants can still name a specific record, because that record's own public page already names it.
This is a discovery tool, not legal, tax or financial advice — every tool result says so in its own governance note, and states only that a profile appears to meet or fail the published criteria, never that a payment will follow.
A null field means the fact is not published anywhere we found it, never a guess filled in on the model's behalf — every tool's governance note says the same.
