Kagi MCP server (name kagimcp) exposes Kagi's web search API via the Model Context Protocol (MCP), enabling Claude Desktop, Claude Code, and OpenAI Codex-based assistants to perform web searches within their interactions. Access to the Kagi search API is gated in beta and requires a KAGI_API_KEY. The server can be installed with UV (Astral) on macOS/Linux or Windows, and can also be installed via Smithery. It can be wired into Claude Desktop via a JSON config and into Claude Code, and can be registered with Codex CLI using codex mcp add kagi, which writes the configuration to ~/.codex/config.toml. The summarizer engine can be customized with KAGI_SUMMARIZER_ENGINE (default Cecil if not set); examples include Cecil and Daphne. You can toggle the HTTP transport with the --http flag (along with --port and --host) for deployment. For debugging, run the MCP Inspector at http://localhost:5173 and use the provided inspector commands. Advanced configuration also supports FASTMCP_LOG_LEVEL for logging. The README includes local/dev setup steps (clone, venv via uv, uv sync) and pose example queries that require tool use, illustrating how to use the server in practice.
