FrontMCP docs

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.

      "type": "string",

}

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.

    "path": {
      "type": "string",
      "minLength": 1,
      "maxLength": 500,

    },

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.

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

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.

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

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.

{
  "type": "object",
  "properties": {
    "section": {
      "description": "Only this part of the docs.",
      "type": "string",
      "enum": [
        "learn",
        "reference",
        "examples",
        "compare"
      ]
    },
    "version": {
      "description": "A documented FrontMCP version, like \"1.9.4\", or a minor, like \"1.9\", for its newest patch. Defaults to the version this endpoint serves.",
      "type": "string",
      "maxLength": 20
    }
  },
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}

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.

{
  "type": "object",
  "properties": {
    "symbol": {
      "type": "string",
      "minLength": 1,
      "maxLength": 120,
      "description": "The name, with or without `@`, `this.` or parentheses."
    },
    "limit": {
      "default": 8,
      "description": "How many entries to return.",
      "type": "integer",
      "minimum": 1,
      "maximum": 30
    },
    "version": {
      "description": "A documented FrontMCP version, like \"1.9.4\", or a minor, like \"1.9\", for its newest patch. Defaults to the version this endpoint serves.",
      "type": "string",
      "maxLength": 20
    }
  },
  "required": [
    "symbol"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}

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; the part about @frontmcp/sdk is enough), or a version range. A lockfile gives the installed version; package.json only the range it allows. Call it first when you can read the project.

{
  "type": "object",
  "properties": {
    "packageJson": {
      "description": "The project's package.json, as it is.",
      "type": "string",
      "maxLength": 100000
    },
    "lockfile": {
      "description": "The project's lockfile, or the lines about @frontmcp/sdk.",
      "type": "string",
      "maxLength": 200000
    },
    "range": {
      "description": "A version or range, like \"1.9.4\" or \"^1.9.0\".",
      "type": "string",
      "maxLength": 100
    }
  },
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}

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.

{
  "type": "object",
  "properties": {
    "query": {
      "type": "string",
      "maxLength": 200,
      "description": "Words to look for, like \"rate limit\", \"deploy to cloudflare\" or \"elicit\"."
    },
    "section": {
      "description": "Only this part of the docs.",
      "type": "string",
      "enum": [
        "learn",

        "examples",
        "compare"
      ]
    },

      "description": "How many sections to return.",

}

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.

  "type": "object",
  "properties": {
    "from": {
      "type": "string",
      "maxLength": 20,

    },
    "to": {
