@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:

Mode	Trigger	Available tools
anonymous	`CLAWHUB_TOKEN` unset	10 read-only tools (search, list, get, scan, moderation, file, resolve, download)
authenticated	`CLAWHUB_TOKEN` set	All 14 tools (adds whoami, publish, delete, undelete)

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.

Sign up at aiwerkmcp.com.
Install ClawHub from the catalog. Leave CLAWHUB_TOKEN empty for anonymous mode (10 read-only tools), or paste a token to unlock all 14.
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)

Tool	Description
`clawhub_search`	Search skills by query string — primary discovery path
`clawhub_list_skills`	List skills with cursor pagination (see caveat below)
`clawhub_get_skill`	Full details for a skill slug
`clawhub_list_versions`	List all versions of a skill
`clawhub_get_version`	Get a specific version (files + security snapshot)
`clawhub_get_scan`	Security scan result for a version
`clawhub_get_moderation`	Moderation verdict and evidence (response wraps under `moderation`)
`clawhub_get_file`	Fetch a single raw file from a skill
`clawhub_resolve`	Resolve version by content hash
`clawhub_download`	Download skill zip (base64 encoded)

Discovery caveat: the live /skills endpoint applies a default server-side filter that may return an empty items[] for ungated browsing. In practice, prefer clawhub_search — it's the reliable entry point for finding skills by keyword. Use clawhub_list_skills with cursor pagination only when you have a specific filter in mind (e.g. nonSuspiciousOnly=true). The highlightedOnly flag is available on clawhub_search but not on clawhub_list_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:

clawhub_list_skills → { items: [...], nextCursor } (not skills)
clawhub_list_versions → { items: [...], nextCursor } (not versions)
clawhub_get_moderation → { moderation: { verdict, ... } } (wrapped)
clawhub_whoami → { user: { handle, ... } } (wrapped)
clawhub_get_moderation returns 404 for skills with no moderation events — this means clean, not missing. For the always-present verdict, read .moderation from clawhub_get_skill.

Authenticated only (CLAWHUB_TOKEN required)

Tool	Description
`clawhub_whoami`	Current user (handle, displayName, image)
`clawhub_publish`	Publish a new skill version
`clawhub_delete`	Soft-delete a skill (reversible)
`clawhub_undelete`	Restore a soft-deleted skill

Environment

Variable	Required	Purpose
`CLAWHUB_TOKEN`	no	Bearer token issued by clawhub.ai. Unlocks auth-only tools and raises rate limits (120/min → 600/min for reads).
`CLAWHUB_BASE_URL`	no	Override the API base URL. Defaults to `https://clawhub.ai/api/v1`.

Rate limits

Anonymous: 120 reads/min per IP, 30 writes/min per IP
Authenticated: 600 reads/min per key, 120 writes/min per key
