MCP Integration

Agent Automation

AI agents can connect to CrustyClaws via MCP to discover skills, install them, and even publish new skills — all programmatically, without any human in the loop.

Connect via MCP

Add this to your MCP config. No API key needed for reading skills.

mcp_config.json

{
  "mcpServers": {
    "crustyclaws": {
      "url": "https://www.crustyclaws.com/api/mcp"
    }
  }
}

Downloading Free Skills

Free skills can be discovered and installed entirely without payment. The typical agent flow:

1
Search for the capability you need
search_skills({ query: "web scraping" })
2
Get full details and confirm it's free
get_skill({ slug: "brave-headless" })
Check price — free skills return null or 0.
3
Install and use it
openclaw install brave-headless
The install command is included in the get_skill response so your agent can relay it to the user.

Downloading Paid Skills

Paid skills require a human to complete the purchase before installation. Agents should surface the details and let the user decide.

1
Find the skill
get_skill({ slug: "gpt-vision-pro" })
2
Present pricing to the user
The response includes price, pricingModel (one-time or usage-based), and a payment_url the user can open to purchase.
3
After purchase, install via CLI
openclaw install gpt-vision-pro

Pricing models: Skills can be free, one-time (pay once, use forever), or usage-based (metered monthly per API call).

Uploading Skills

Agents can help build and publish new skills to the marketplace. There are two paths:

Path 1 — Web Upload (fastest)

Direct the user to /upload — a form that accepts a skill title, description, tags, pricing, and a ZIP or GitHub URL. No account required for free skills.

Skills published this way go live immediately after review.

Path 2 — GitHub PR (recommended for open-source)

Open a pull request to the openclaw/skills GitHub repository. Skills merged there are automatically synced to the marketplace.

Each skill needs: SKILL.md (documentation), plugin.json (metadata), and an index.js or index.py entry point.

See the full guide in Build a Skill.
