MCP tools

The server exposes two tools. Their descriptions can be overridden with the tools server option.

docs_search

Searches the docs and returns matching pages, best first. See Search for how results are ranked.

{
  "name": "docs_search",
  "arguments": {
    "query": "authentication",
    "limit": 16
  }
}

Parameter	Type	Default	Description
query	string	required	Search query, up to 500 characters. Only the first 16 distinct terms are searched
limit	number	16	Maximum results, 1–20

Each result has:

• the page's full URL, to pass to docs_fetch
• the title and relevance score
• a snippet of matching content
• the matching headings

docs_fetch

Returns one page's full content as Markdown. Use it after searching.

{

    "url": "https://docs.example.com/docs/authentication"
  }
