webmcp.com and nekuda: WebMCP directory and tooling
Who ships WebMCP tools, and how to build your own.
Agent Readiness Compare editors · Spec status checked September 2026
Answer
webmcp.com is a live directory of websites that expose tools to agents through WebMCP, maintained by nekuda.ai, with a free read-only API. It is not the WebMCP specification. nekuda builds the tooling: AgentLane to manage WebMCP tools and monitor agent sessions, a WebMCP Kit plugin for coding agents, an npm SDK, and a Chrome extension for inspecting tools.

1.What is webmcp.com?
webmcp.com lists sites that expose WebMCP tools, lets you browse tools and inspect their input schemas, and verifies tools are live before listing a site. It offers read-only JSON endpoints for agents, such as /api/v1/sites and /api/v1/lookup, with CORS open and no authentication. It is maintained by nekuda.ai and built on the W3C webmachinelearning/webmcp proposal; it is a directory, not the standards body.

3.How does this relate to ora.ai's WebMCP audit?
They do different jobs. nekuda's tools help you build and run WebMCP tools; ora.ai's WebMCP audit scores the tools a page exposes. A team shipping WebMCP could use both: one to build, one to check.
4.Where is it strong, and what should you watch?
Strong
- The most complete WebMCP build tooling we found.
- A public, free API for the directory.
- Session and tool-call monitoring in AgentLane.
Watch
- WebMCP is a proposal in active development.
- Pricing for AgentLane is not published.
- Covers WebMCP only; discovery, markdown and bot trust need other tools.
