webmcp is a skill for Claude Code, Codex from berkayoztunc/orquestra. It costs 0 tokens per session (62 once invoked), scanned A, original, MIT.

A browser integration that registers functions exposed by a website when WebMCP is available. WebMCP is a way for web pages to expose callable tools to an agent.

In plain words
What is it for?
Registering tools for searching programs, opening program pages, and opening documentation.
Why use it?
It gives the site a defined connection between its interface and browser-available tools, and removes those registrations when the site closes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

webmcp 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 9d 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 actually says

WebMCP Support

Orquestra registers browser-exposed tools when WebMCP is available.

Exposed tools

  • search_programs
  • open_program_page
  • open_docs

The site registers tool definitions on page load and cleans them up when the app unmounts.

Changes

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.

webmcp is a skill published in the GitHub repository berkayoztunc/orquestra (23 stars, last pushed 22d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 62 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
