What it does
WebMCP Kit makes a website or web app usable by browser agents. The plugin reads your repository, proposes a WebMCP tool plan and waits for approval. After you agree it implements the tools with `@nekuda/webmcp-sdk` and verifies each in a real browser. A check ends as verified, failed or could-not-verify, and a failed tool never ships. Three skills ship inside: `implement` builds tools, `verify` checks existing ones, and `connect-existing-tools` wires existing app logic in as tools. The agent works through your own client-side functions and does not need to parse the page. Everything runs locally, code never leaves the machine and there is no hosted scanner.
Who it is for. Web developers who want to give browser agents reliable access to their application functions.
Good fit when
- An app should become agent-ready so a browser agent calls tools instead of parsing the DOM.
- The code already has WebMCP tools and you must confirm they register and work.
- Existing client functions should be exposed as tools with stable keys.
- A tool plan must get your approval before any code is written.
Not a fit when
- The site is static and offers no agent actions.
- You want to send code to a third-party cloud scanner.
- You cannot run the app in a browser for verification.
Example request
Use WebMCP Kit, read the repository, propose a tool plan for my app and wait for my approval.Limitations
The plugin edits application code, so read the tool plan and verification results before merging. Verification needs a browser and a running app, and some steps open a review interface on the local machine. On Codex the install registers `PreToolUse` and `Stop` hooks that only carry feedback from the review window to the agent, visible through `/hooks`. WebMCP capabilities depend on browser support and the SDK version, so check them against the documentation.
How to disable. Remove the plugin with the Claude Code or Codex plugin commands, and for Cursor delete the skills from the directory. WebMCP tools and the SDK dependency added to the project are removed manually.
FAQ
How do I install the plugin in Claude Code?
Run `/plugin marketplace add nekuda-ai/webmcp-kit`, then `/plugin install webmcp-kit@nekuda`.
How do I install it in Codex?

How do I install the skills in Cursor?
Run `npx skills add nekuda-ai/webmcp-kit --skill '*' --agent cursor`: the implement, verify and connect-existing-tools skills are installed.
