Overview

This MCP server integrates with Sourcegraph, a universal code search platform that enables searching across multiple repositories and codebases. It provides powerful search capabilities with advanced query syntax, making it ideal for AI assistants that need to find and understand code patterns across large codebases.

Features

  • Code Search: Search across codebases using Sourcegraph's powerful query language

  • Advanced Query Language: Support for regex patterns, file filters, language filters, and boolean operators

  • Repository Discovery: Find repositories by name and explore their structure

  • Content Fetching: Browse repository files and directories

  • AI Integration: Designed for LLM integration with guided search prompts

Prerequisites

  • Sourcegraph Instance: Access to a Sourcegraph instance (either sourcegraph.com or self-hosted)

  • Python 3.10+: Required for running the MCP server

  • UV (optional): Modern Python package manager for easier dependency management

Installation

Using UV (recommended)

# Install dependencies uv sync # Run the server uv run python -m src.main

Using pip

# Create virtual environment python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate # Install package pip install -e . # Run the server python -m src.main

Using Docker

# Build the image docker build -t sourcegraph-mcp . # Run the container with default ports docker run -p 8000:8000 -p 8080:8080 \ -e SRC_ENDPOINT=https://sourcegraph.com \ -e SRC_ACCESS_TOKEN=your-token \ sourcegraph-mcp # Or run with custom ports docker run -p 9000:9000 -p 9080:9080 \ -e SRC_ENDPOINT=https://sourcegraph.com \ -e SRC_ACCESS_TOKEN=your-token \ -e MCP_SSE_PORT=9000 \ -e MCP_STREAMABLE_HTTP_PORT=9080 \ sourcegraph-mcp

Configuration

Required Environment Variables

  • SRC_ENDPOINT: Sourcegraph instance URL (e.g., https://sourcegraph.com)

Optional Environment Variables

  • SRC_ACCESS_TOKEN: Authentication token for private Sourcegraph instances

  • MCP_SSE_PORT: SSE server port (default: 8000)

  • MCP_STREAMABLE_HTTP_PORT: HTTP server port (default: 8080)

Usage with AI Tools

Cursor

After running the MCP server, add the following to your .cursor/mcp.json file:

{ "mcpServers": { "sourcegraph": { "url": "http://localhost:8080/sourcegraph/mcp/" } } }

MCP Tools

This server provides three powerful tools for AI assistants:

🔍 search

Search across codebases using Sourcegraph's advanced query syntax with support for regex, language filters, and boolean operators.

📖 search_prompt_guide
