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 plugin for Claude Code and Codex that does the work of adding 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.

Install

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

Then, in your website’s repo:

/webmcp-kit:implement

Quickstart

From repo to agent-ready in one session.

How it works

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

Skills

Reference for /webmcp-kit:implement and /webmcp-kit:verify.

SDK

@nekuda/webmcp-sdk — the small browser SDK the generated code is built on.

What’s in the kit

Piece	What it does
`/webmcp-kit:implement`	Reads your repo, plans the tools, writes them after you approve, verifies them.
`/webmcp-kit:verify`	Checks a running site: tools registered on the right pages, working when called.
`@nekuda/webmcp-sdk`	The browser SDK the generated tools are built on. The plugin wires it in for you.

The one rule that matters

Nothing is written before you approve it. The plan — which tools, wired to what, worded how — is presented to you first, and only an explicit approval moves it forward. That review gate is the product, not a formality.
