webmcp-kit

webmcp-kit is a plugin for Claude Code from nekuda-ai/webmcp-kit. Its manifest loads nothing; the 3 skills, 1 command, 2 hooks it bundles cost 197 tokens per session together, scanned A, original, MIT.

A plugin for adding WebMCP tools to a web application. WebMCP is a way for browser-based agents to use clearly defined actions provided by a website.

In plain words
What is it for?
Use it to inspect a web app, plan the tools it should expose, implement them with the @nekuda/webmcp-sdk package, and verify them in the browser.
Why use it?
It turns the work of exposing app actions to agents into a reviewable implementation process and checks that the resulting tools work in a browser.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

webmcp-kit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 3 skills, 1 command, 2 hooks travel with it, and installing the plugin installs all of them — 197 tokens a session between them. Each is measured on its own page, and each can be installed alone.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
