tlon-mcp
Tlon MCP Server — an open-source Model Context Protocol server (first-party, tloncorp GitHub org) that exposes tools for interacting with Tlon Messenger agents over a running Urbit ship. Self-hosted; stdio (default) or http transport. Configured with the ship URL/name and +code access code. A companion `mcp` Hoon agent (tloncorp/mcp) acts as an MCP proxy and OAuth grant-cache on the ship.
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.
