Sourcegraph code search, semantic search, go-to-definition, find-references, and diff search.

io.github.sourcegraph/mcp (Sourcegraph MCP Server)

The Sourcegraph MCP server (for a Sourcegraph instance) provides MCP-compatible access to Sourcegraph code search and code intelligence capabilities. It supports configuring against Sourcegraph Cloud or a private Sourcegraph deployment, allowing connected MCP clients to use workflows such as code search and navigation within the user’s own Sourcegraph server.

🛠️ Key Features

Code search and semantic search
Go-to-definition
Find-references
Diff search

🚀 Use Cases

Discover repositories
Read files
Run keyword and semantic searches
Navigate symbols and look up references
Search code changes via diffs

⚡ Developer Benefits

Standard MCP interface for Sourcegraph workflows
Access to repository discovery, search, and code intelligence through MCP clients

⚠️ Limitations

Capabilities described are specific to Sourcegraph code search and code intelligence workflows available in the connected Sourcegraph instance.

Sourcegraph MCP Server

This registry entry represents the Sourcegraph MCP server for a Sourcegraph instance. It can be configured against Sourcegraph Cloud or a private Sourcegraph deployment, so users can connect MCP-compatible clients to their own Sourcegraph server.

At a high level, the Sourcegraph MCP server gives agents and applications access to Sourcegraph code search and code intelligence capabilities through a standard MCP interface. That includes common workflows such as repository discovery, file reads, keyword and semantic search, symbol navigation, references, and code-change exploration.

Configuration

Configure the server with the hostname of your Sourcegraph instance. This entry uses the standard Sourcegraph MCP endpoint:

https://{sourcegraph_hostname}/.api/mcp

For private Sourcegraph instances, set sourcegraph_hostname to your internal or company-hosted Sourcegraph server hostname.

Authentication is handled by Sourcegraph. Depending on the MCP client, this is typically done with browser-based OAuth or a Sourcegraph access token. This MCP config defaults to OAuth.

Notes

This README intentionally keeps client-specific setup details light because MCP integration steps can change over time. For the current Sourcegraph MCP server behavior, supported authentication modes, and client-specific setup instructions, see the official Sourcegraph documentation:
