MCP server

An AI agent can use the same data through MCP at https://greasecleaning.fyi/mcp. It takes POST only: a GET in a browser gives 405. The server uses Streamable HTTP, keeps no session and needs no key. It reads only. It has the same rate limit, the same public fields and the same credit line as the API. The server card describes it.

Add it to Claude Code

claude mcp add --transport http greasecleaning https://greasecleaning.fyi/mcp

Add it to a client that reads an mcpServers file, such as Cursor (.cursor/mcp.json)

{
  "mcpServers": {
    "greasecleaning": {
      "url": "https://greasecleaning.fyi/mcp"
    }
  }
}

List the tools with curl

curl -X POST "https://greasecleaning.fyi/mcp" -H "content-type: application/json" -H "accept: application/json, text/event-stream" -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Responses

A successful response has data and meta. A list response also has page, with these fields:

limit
: items on each page.
total
: items that match.
nextCursor
: send it back as cursor, with the same filters and limit. It is null on the last page.
capped
: true when more items match than the cursor can reach.
fuzzy
: true when the items are close matches for q.

An error has error (a sentence), code and sometimes details. Branch on code: invalid_parameter, invalid_cursor, not_found, method_not_allowed, rate_limited, internal_error, unavailable.

Rate limits and caching

Each client may send 300 requests in 60 seconds. Every GET response has RateLimit-Limit and RateLimit-Policy. Over the limit you get 429 with Retry-After: wait that many seconds. The limit is counted at each Cloudflare location.

A successful response sends Cache-Control: public, max-age=60, s-maxage=300, stale-while-revalidate=600 and an ETag. Send the ETag back as If-None-Match to get 304 with no body.

Credit and licenses

Show this credit line next to the data you display:

Data from Grease Cleaning (https://greasecleaning.fyi). Each record keeps the license of its source, listed in meta.sources. A listing is a record, not an endorsement.

Every response lists its sources in meta.sources. Keep a source's license when you reuse its records.
