Capabilities Txt Registry

Overview

Capabilities Txt Registry is an MCP server that lets you discover and query what websites across the agentic web can do. It connects directly to the capabilities.txt registry, exposing website capabilities as tools your AI assistant can invoke. This makes it easy to understand the functionality available on any site participating in the protocol.

The server runs remotely at https://capabilitiestxt.org/api/mcp with no authentication required and nothing to install locally. You simply point your MCP client at the endpoint and connect. The latest release is v0.1.0, and the source code is available at capabilityhostprotocol/capabilities-txt on GitHub.

Capabilities Txt Registry belongs in the AI & Agents category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server, claim your listing on mcp.site to verify ownership and keep the information up to date.
