Claude Code:

claude mcp add --transport http agent-cold-email https://api.coldrig.dev/mcp --header "Authorization: <YOUR_VALUE>"

Or add to your MCP client config:

{
  "mcpServers": {
    "agent-cold-email": {
      "url": "https://api.coldrig.dev/mcp",
      "headers": {
        "Authorization": "<YOUR_VALUE>"
      }
    }
  }
}

• Authorization required secret — Bearer token from POST /signup (free, no card) — or run `npx agent-cold-email demo` first

Package (npm 0.2.2)

npx -y [email protected]

Or add to your MCP client config:

{
  "mcpServers": {
    "agent-cold-email": {
      "command": "npx",
      "args": [
        "-y",
        "[email protected]"
      ],
      "env": {
        "AGENT_COLD_EMAIL_API_KEY": "<YOUR_VALUE>"
      }
    }
  }
}

• AGENT_COLD_EMAIL_API_KEY secret — Bearer token from POST /signup (free, no card) — or run `npx agent-cold-email demo` first. Optional at startup: without it, `initialize`/`tools/list` still work (unauthenticated introspection), but every `tools/call` fails until a key is set.
• AGENT_COLD_EMAIL_BASE_URL — Override the API base URL (default: https://api.coldrig.dev)
