Install Clawhub in Claude Code, Cursor or VS Code

Runs npx -y @aiwerk/mcp-server-clawhub on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Clawhub repository's README, as published. We do not edit it. Read it on GitHub

@aiwerk/mcp-server-clawhub

MCP server for the ClawHub.ai skill catalog.

Browse, search, inspect, download, and (when authenticated) publish skills from the ClawHub registry through the Model Context Protocol.

Two modes

The server adapts to whether a token is configured:

The authenticated tools are simply not registered in anonymous mode — tools/list will not advertise them.

Install

Two ways to run this server — pick the one that fits.

Option 1 — Hosted (zero setup)

No local runtime — if you set a token, it's AES-256-GCM encrypted server-side via HashiCorp Vault.

  1. Sign up at aiwerkmcp.com.
  2. Install ClawHub from the catalog. Leave CLAWHUB_TOKEN empty for anonymous mode (10 read-only tools), or paste a token to unlock all 14.
  3. Point your MCP client (Claude.ai, Cursor, Hermes, …) at your hosted endpoint:
https://bridge.aiwerk.ch/u/<your-user-id>/mcp

with your Bearer token.

Option 2 — Self-hosted (npx)

Run directly — you manage the token:

npx -y @aiwerk/mcp-server-clawhub

Or in your MCP client config:

{
  "mcpServers": {
    "clawhub": {
      "command": "npx",
      "args": ["-y", "@aiwerk/mcp-server-clawhub"],
      "env": {
        "CLAWHUB_TOKEN": "optional - unlocks publish/delete/whoami"
      }
    }
  }
}

Tools

Read-only (anonymous + authenticated)

Discovery caveat: the live /skills endpoint applies a default server-side filter that may

return an empty items[] for ungated browsing. In practice, prefer clawhubsearch** — it's the

reliable entry point for finding skills by keyword. Use clawhublistskills with cursor pagination

only when you have a specific filter in mind (e.g. nonSuspiciousOnly=true). The highlightedOnly

flag is available on clawhubsearch but not on clawhublist_skills.

Wire shapes worth knowing

Some live API responses differ from the published OpenAPI spec. The types in src/types.ts follow the real wire shape:

not missing. For the always-present verdict, read .moderation from clawhubgetskill.

  • clawhublistskills → { items: [...], nextCursor } (not skills)
  • clawhublistversions → { items: [...], nextCursor } (not versions)
  • clawhubgetmoderation → { moderation: { verdict, ... } } (wrapped)
  • clawhub_whoami → { user: { handle, ... } } (wrapped)
  • clawhubgetmoderation returns 404 for skills with no moderation events — this means clean,

Authenticated only (CLAWHUB_TOKEN required)
