WebMCP Kit

Make your website accessible to AI agents by exposing WebMCP tools they can call.

AI agents interact with websites through the UI. They parse the page, locate elements, and simulate clicks. This is slow, brittle, and breaks when the interface changes.

WebMCP is a web standard that fixes this. A page can hand the agent a small set of typed tools — search products, add to cart, book a demo — that run through the site’s own code. The agent stops guessing at your UI and starts calling functions you defined.

WebMCP Kit is a coding-agent plugin that works with Claude Code, Codex, and Cursor to add those tools to your site. It reads your codebase, proposes a short plan of tools worth having, waits for your approval, writes the code, and verifies every tool in a real browser. Tools are chosen around the journeys that matter on your site — what a visitor actually comes to do — so an agent gets the best path through your site, not a wrapper around every endpoint.

Add tools with a coding agent

Let WebMCP Kit plan, implement, and verify tools in your app.

Write tools with the SDK

Use @nekuda/webmcp-sdk to call your existing app functions from TypeScript or JavaScript.

Verify existing tools

Check registration, execution, and the visible result in a real browser.

Install

/plugin marketplace add nekuda-ai/webmcp-kit
/plugin install webmcp-kit@nekuda

Using Codex or Cursor? See the Installation guide for the matching command.

Then, in your website’s repo:

/webmcp-kit:implement

How it works

The mental model: journeys, the approval gate, and what the kit will never do.

Skills

Add tools, connect existing tools, or check that they work.

Verification example

Run a local example. Call a tool and check the page result.

What’s in the kit

Piece	What it does
`implement`	Add WebMCP tools to your site.
