Which integrations are available for this server?

Retrieves file contents from Mozilla repositories via [GitHub](/mcp/servers/integrations/github)'s raw content API. Provides access to [Mozilla](/mcp/servers/integrations/mozilla)'s Searchfox code search service, enabling code search across Mozilla repositories (mozilla-central, autoland, beta, release, ESR branches, and comm-central) and retrieval of file contents from these repositories.

Searchfox MCP Server

A Model Context Protocol (MCP) server that provides access to Mozilla's Searchfox code search service. This server enables AI assistants to search through Mozilla's codebases and retrieve file contents directly.

Features

Code Search: Search across Mozilla repositories using Searchfox's powerful indexing
File Retrieval: Get file contents from Mozilla repositories via GitHub raw content API
Multiple Repositories: Support for mozilla-central, autoland, mozilla-beta, ESR branches, and comm-central
Flexible Search Options: Case sensitivity, regular expressions, and path filtering

Available Tools

`search_code`

Search for code patterns across Mozilla repositories using Searchfox.

Parameters:

query (string): Search query using exact literal string matching (no OR logic, no phrase matching)
repo (string, optional): Repository to search in (defaults to "mozilla-central")
path (string, optional): Filter results by file path using glob patterns with ^ and $ operators
case (boolean, optional): Enable case sensitive search (default: false)
regexp (boolean, optional): Treat query as regular expression pattern (default: false)
limit (number, optional): Maximum number of results (default: 50)

Important Search Notes:

Uses exact string matching only - multiple words are treated as a single literal string
No search operators, OR logic, or phrase matching with quotes
For broader searches, use separate queries or enable regexp mode

Supported Repositories:

mozilla-central (default) → GitHub main branch
autoland → GitHub autoland branch
mozilla-beta → GitHub beta branch
mozilla-release → GitHub release branch
mozilla-esr115, mozilla-esr128, mozilla-esr140 → Corresponding ESR branches
comm-central → GitHub mozilla/releases-comm-central main branch

`get_file`

Retrieve the contents of a specific file from a Mozilla repository. Files are retrieved from GitHub raw content API (https://raw.githubusercontent.com/)

Parameters:

path (string): File path within the repository
repo (string, optional): Repository name (defaults to "mozilla-central")

Usage

First clone the repository and run:

# Install dependencies and build the project npm install npm run build

Then add the MCP server to your client.

Claude Desktop Configuration

Your claude_desktop_config.json file should look like this:

{ "mcpServers": { "searchfox": { "command": "node", "args": [ "/path/to/searchfox-mcp/dist/index.js" ] }, } }

Development

# Install dependencies npm install # Build the project npm run build # Run in development mode with hot reload npm run dev # Type checking without emitting files npm run tsc # Run linting npm run lint # Fix linting issues automatically npm run lint:fix # Format code npm run format # Check formatting npm run format:check

Configuration

The server runs via stdio transport and communicates using the MCP protocol. Configure your MCP client to connect to this server using the built executable.
