Cursor config for Claude Skills MCP Server

uvx claude-skills-mcp
{
  "mcpServers": {
    "claude-skills-mcp-server": {
      "command": "uvx",
      "args": [
        "claude-skills-mcp"
      ]
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

Setup steps

  2. 2Paste the Claude Skills MCP Server config below into the "mcpServers" object.
  3. 3Fill in placeholder secrets, then save.
  4. 4Cursor reloads MCP servers automatically — check Settings → MCP for a green status dot.
  5. 5Ask Cursor to use one of Claude Skills MCP Server's tools to confirm it's connected.

  • uv / uvx installed (Astral) to run the package
  • Python 3.12
  • Internet access on first run to download the backend (~250 MB) and fetch skill sources from GitHub
  • An MCP-compatible client such as Cursor
