Endpoints of the Eating Disorder Directory API, with their parameters
Endpoint	Returns	Parameters
`GET /api/v1/listings`	Search and list listings	`q` (query, optional, string) Search text, with at least one letter or digit. Matches name, categories, attributes, description and place. Typos fall back to close matches. `country` (query, optional, string) ISO 3166-1 alpha-2 country code, any case.

MCP server

An AI agent can use the same data through MCP at https://eatingdisorder.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.

search_listings: : Search published eating disorder programs by text, place and category.
get_listing: : Get one published eating disorder program by its slug.
list_places: : List countries, regions and cities that have eating disorder programs.
list_categories: : List categories with their eating disorder program counts.
get_stats: : Get the number of published eating disorder programs, places and categories, and when the data last changed.
list_sources: : List where the eating disorder program data comes from, with the license and refresh of each source.

Add it to Claude Code

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

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

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

List the tools with curl

curl -X POST "https://eatingdisorder.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.

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 Eating Disorder Directory (https://eatingdisorder.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.

SAMHSA Behavioral Health Treatment Services Locator (FindTreatment.gov), N-SUMHSS facility data: license Public domain (work of the US federal government, 17 U.S.C. 105; FindTreatment.gov dedicates the work worldwide under CC0 1.0), refreshed weekly
State health facility licensing lists: license Public records; each state names its own reuse terms, refreshed quarterly
