Install / run

uv tool install biomcp-cli

{
  "mcpServers": {
    "biomcp": {
      "command": "biomcp",
      "args": [
        "serve"
      ]
    }
  }
}

Install / run

uvx mcp-server-fetch

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "fetch-reference": {
      "command": "uvx",
      "args": [
