Model Context Protocol (MCP)

Ollama Code Review fully supports the Model Context Protocol (MCP), enabling seamless integration between VS Code and AI agents like Claude Desktop.

Built-in MCP Server

The extension includes a built-in MCP server that exposes its code review and context gathering capabilities to external AI tools.

Key Capabilities

• Review Tools: Trigger code reviews, explain changes, and generate summaries.
• Context Tools: Resolve imports, find related tests, and search the codebase.
• File Tools: Read, write, and list files within the current workspace.
• Commit Tools: Generate and apply commit messages.

Configuration

By default, the built-in server is disabled. You can enable it in your VS Code settings:

Setting	Description	Default
ollama-code-review.mcp.enabled	Enable the built-in MCP server	false
ollama-code-review.mcp.port	The port the server listens on	19840
ollama-code-review.mcp.autoKillPortConflicts	Automatically terminate other processes on the MCP port	false
ollama-code-review.mcp.allowedOrigins	Allowed browser origins for companion extensions	["chrome-extension://*"]
ollama-code-review.mcp.authToken	Optional secret token for browser client security	""

Integration with Claude Desktop

To use this extension with Claude Desktop, add the following to your claude_desktop_config.json. This uses mcp-remote to bridge the extension's HTTP server to Claude's Stdio client:

{
  "mcpServers": {
    "ollama-code-review": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "http://localhost:19840/mcp",
        "--allow-http"
      ]
    }
  }
}

External MCP Servers

You can also connect Ollama Code Review to other MCP servers. This allows the extension's AI to use tools provided by those servers during its review process.

Configuration

Add external servers via the ollama-code-review.mcp.externalServers setting:

"ollama-code-review.mcp.externalServers": {
  "sqlite-explorer": {
    "command": "npx",
    "args": ["-y", "@modelcontextprotocol/server-sqlite", "--db", "path/to/your.db"]
  }
}

MCP Mode (Clipboard)

When mcp.enabled is set to true, the extension changes its behavior for manual review triggers: Instead of sending the review request to an LLM directly, it copies the full review prompt to your clipboard.

This is designed for workflows where you want to manually paste the context into an external chat interface (like Claude.ai or ChatGPT) that is also using the MCP server.
