get_example Read-only

Returns a runnable example from a FrontMCP docs page: the files of one of its Playgrounds, with their tests, as the docs run them. Without `index`, lists the page's Playgrounds (numbered from 1, in page order) with their section and files.

pathstring, required

The page, like /reference/sdk/tool or a frontmcp.dev URL.

indexinteger

Which Playground on the page, from 1.

versionstring

A documented FrontMCP version, like "1.9.4", or a minor, like "1.9", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves.

    }
  }
}

get_page

Returns a FrontMCP docs page as Markdown, or one section of it. `path` is a path (/reference/sdk/tool), a frontmcp.dev URL, or an old docs.agentfront.dev URL, which is mapped to its page here; a #anchor in it, or `section`, picks the section. A very long page comes back as its introduction and its sections, to read one at a time. Use it once search_docs, lookup_api or list_pages has given a path, or for a docs URL you already have. The page is the one documented for `version`.

read-only

Argument	Type	Description
path*	string	The page: /reference/sdk/tool, https://frontmcp.dev/learn/your-first-tool#declaring-a-tool, or an old docs.agentfront.dev URL.
section	string	A section's anchor, like "options". Overrides an anchor in `path`.
version	string	A documented FrontMCP version, like "1.9.4", or a minor, like "1.9", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves.

    }
  }
}

get_skill

FrontMCP's skills catalog (@frontmcp/skills): instructions for building with FrontMCP, from setting up a project to production readiness. Without `name`, lists the skills. With `name`, returns its SKILL.md and the reference files beside it; with `file` too, that file. Skills are step-by-step guides written for coding agents: for the docs themselves use search_docs or get_page, and for runnable code get_example. The catalog is the newest FrontMCP release's, so the tool takes no version.

read-only

Argument	Type	Description
file	string	One of the skill's reference files, as listed, like "references/create-tool.md".
name	string	A skill, like "frontmcp-development".

Input schema (JSON)

{
  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "properties": {
    "file": {
      "type": "string",
      "maxLength": 300,
      "description": "One of the skill's reference files, as listed, like \"references/create-tool.md\"."
    },
    "name": {
      "type": "string",
      "maxLength": 100,
      "description": "A skill, like \"frontmcp-development\"."
    }
  }
}

get_versions

Lists the FrontMCP releases these docs cover, newest first, each with its release notes and the endpoint that pins it (https://mcp.frontmcp.dev/<version>). Says which version this endpoint serves. To find the version a project uses, call resolve_version.

read-only

No arguments.

Input schema (JSON)

{
  "type": "object",
  "properties": {}
}

list_pages

Lists the FrontMCP docs as the site's sidebar has them, in reading order: Learn (lessons), Reference (APIs, options, deployment), Examples and Compare, each in groups of pages with their titles and paths. Use it to browse, or to find a page by topic when you don't know its name; to find something specific, search_docs or lookup_api is faster. Read a page it lists with get_page. The pages are those of `version`.

read-only

Argument	Type	Description
section	string	Only this part of the docs.
version	string	A documented FrontMCP version, like "1.9.4", or a minor, like "1.9", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves.

Input schema (JSON)

        "reference",

      ],
      "type": "string",
      "description": "Only this part of the docs."
    },
    "version": {
      "type": "string",
      "maxLength": 20,
      "description": "A documented FrontMCP version, like \"1.9.4\", or a minor, like \"1.9\", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves."
    }
  }
}

lookup_api

Finds a FrontMCP API by name in the Reference pages: a decorator (`@Tool`), function or method (`createFetchHandler`, `this.elicit`), option (`inputSchema`, `throttle`), error code (`TOOL_NOT_FOUND`), CLI command or flag (`--target`). Returns the matching entries, most relevant first, each with what the docs say, its page and anchor. Read more with get_page.

read-only

Argument	Type	Description
limit	integer	How many entries to return.
symbol*	string	The name, with or without `@`, `this.` or parentheses.
version	string	A documented FrontMCP version, like "1.9.4", or a minor, like "1.9", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves.

      "description": "A documented FrontMCP version, like \"1.9.4\", or a minor, like \"1.9\", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves."
    }
  }
}

resolve_version

Says which documented FrontMCP version a project should read, and the endpoint that pins it. Pass the project's package.json, its lockfile (package-lock.json, yarn.lock or pnpm-lock.yaml, including relevant importers and all SDK resolutions), or a version range. An unambiguous lockfile identifies an installation; package.json only the range it allows. If several installations exist, select an npm/pnpm workspace or pass an exact installedVersion read from the resolved SDK package. Call it first when you can read the project.

read-only

Argument	Type	Description
range	string	A version or range, like "1.9.4" or "^1.9.0".
lockfile	string	The project's lockfile, including the selected importer and all SDK resolutions. A truncated fragment must preserve that context.
workspace	string	Workspace/importer path in an npm or pnpm lockfile, for example "." or "packages/api". Required when installations are ambiguous.
packageJson	string	The project's package.json, as it is.
installedVersion	string	Exact release read from this project's resolved @frontmcp/sdk/package.json. Takes precedence over a shared lockfile; never guess it from a range.

    "range": {

      "maxLength": 100,
      "description": "A version or range, like \"1.9.4\" or \"^1.9.0\"."
    },
    "lockfile": {
      "type": "string",
      "maxLength": 200000,
      "description": "The project's lockfile, including the selected importer and all SDK resolutions. A truncated fragment must preserve that context."

    "workspace": {
      "type": "string",
      "maxLength": 300,
      "description": "Workspace/importer path in an npm or pnpm lockfile, for example \".\" or \"packages/api\". Required when installations are ambiguous."
    },
    "packageJson": {
      "type": "string",
      "maxLength": 100000,
      "description": "The project's package.json, as it is."
    },
    "installedVersion": {
      "type": "string",
      "maxLength": 40,
      "description": "Exact release read from this project's resolved @frontmcp/sdk/package.json. Takes precedence over a shared lockfile; never guess it from a range."
    }
  }
}

search_docs

Full-text search over the FrontMCP docs, by section: page titles, section headings and prose. Returns up to `limit` sections, best first, each with its page, heading, path (with the #anchor) and the start of its text. Read one with get_page. For an API, option or error code by name, lookup_api is more precise.

read-only

Argument	Type	Description
limit	integer	How many sections to return.
query*	string	Words to look for, like "rate limit", "deploy to cloudflare" or "elicit".
section	string	Only this part of the docs. Choose blog explicitly for dated articles.
version	string	A documented FrontMCP version, like "1.9.4", or a minor, like "1.9", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves.

    }
  }
}

whats_changed

What changed in FrontMCP after `from` up to `to` (the endpoint's version by default): each release's notes, every note the docs make about a change ("Changed in 1.9.5: before, …"), with its page and section, and, when both versions are documented, which pages changed. `from` can be any release, documented or not. Use it to upgrade a project, or to check whether docs for one version hold for another.

read-only

Argument	Type	Description
to	string	A documented FrontMCP version, like "1.9.4", or a minor, like "1.9", for its newest patch. Pass the version resolve_version found for the project. Defaults to the version this endpoint serves.
from*	string	The older release, like "1.9.2" or "1.8".
limit	integer	How many notes to return, newest first.
section	string	Only notes from this part of the docs.
