MCP Server

The spore.host MCP server exposes truffle and spawn as tools for AI assistants that support the Model Context Protocol — including Claude Desktop and Cursor.

Install

brew install spore-host/tap/spore-host-mcp

Configure

Add to ~/.claude/claude_desktop_config.json:

{
  "mcpServers": {
    "spore-host": {
      "command": "/usr/local/bin/spore-host-mcp"
    }
  }
}

Restart Claude Desktop. A hammer icon in the input bar confirms the server is connected.
