+# Sourcegraph MCP Server
+
+<p className="subtitle">Connect AI agents and applications to your Sourcegraph instance's code search and analysis capabilities.</p>
+
+<TierCallout>
+  Supported on [Enterprise](/pricing/enterprise) plans.
+</TierCallout>
+<Callout type="note">This feature is [experimental](admin/beta_and_experimental_features#experimental-features) and might change or be removed in the future.</Callout>
+
+The Sourcegraph Model Context Protocol (MCP) Server provides AI agents and applications with programmatic access to your Sourcegraph instance's code search, navigation, and analysis capabilities through a standardized interface.
+
+## Server Endpoint
+
+The MCP server is available at:
+
+```
+https://your-sourcegraph-instance.com/.api/mcp/v1
+```
+
+## Authentication
+
+The Sourcegraph MCP server supports two authentication methods:
+
+### OAuth 2.0
+
+For programmatic access without storing credentials, use OAuth 2.0 with device flow or authorization code flow with PKCE:
+
+#### Prerequisites
+
+Before using OAuth, you must create an OAuth application in your Sourcegraph instance. Follow the instructions [here](/admin/oauth_apps#creating-an-oauth-app). (Note: you will need the `user:all` scope) 
+
+### Authorization Header
+
+Include your token in the Authorization header:
+
+```
+Authorization: token YOUR_ACCESS_TOKEN
+```
+
+## Available Tools
+
+The MCP server provides these tools for code exploration and analysis:

+
+## Usage Examples
+
+### Finding Authentication Code
+
+```json
+{
+  "method": "tools/call",
+  "params": {
+    "name": "sg_nls_search",
+    "arguments": {
+      "query": "authentication login user"
+    }
+  }
+}
+```
+
+### Reading a Specific File
+
+```json
+{
+  "method": "tools/call",
+  "params": {
+    "name": "sg_read_file",
+    "arguments": {
+      "repo": "github.com/myorg/myrepo",
+      "path": "src/auth/login.go",
+      "startLine": 1,
+      "endLine": 50
+    }
+  }
+}
+```
+
+### Finding Recent Changes
+
+```json
+{
+  "method": "tools/call",
+  "params": {
+    "name": "sg_commit_search",
+    "arguments": {
+      "repos": ["github.com/myorg/myrepo"],
+      "messageTerms": ["bug fix"],
+      "after": "1 week ago"
+    }
+  }
+}
+```
+
+## Best Practices
+
+1. **Repository Scoping:** Use `sg_list_repos` first to find relevant repositories for better performance
+2. **Progressive Search:** Start with broad searches (`sg_nls_search`) then narrow with specific tools
+3. **File Verification:** Use `sg_list_files` before `sg_read_file` to verify file existence
+4. **Pagination:** Use `after`/`before` cursors for large result sets
+5. **Tool Combinations:** Chain tools together (e.g., `sg_list_repos` → `sg_commit_search`)
