Walnut MCP Server
Walnut publishes a first-party Model Context Protocol server that wraps the Walnut Customer Data API and exposes its three read operations as MCP tools to Claude Desktop, Cursor, VS Code and any other MCP client. It is a locally-run bridge, not a hosted endpoint: the provider distributes it as source inside the Walnut monorepo, the operator builds it and runs it over stdio (or an optional local HTTP transport on 127.0.0.1:3001), and every call still carries the operator's own Walnut Customer Data API key. There is no Walnut-hosted MCP URL an agent can reach on its own.
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
