Waxell Developer MCP

A purpose-built MCP server that gives coding agents instant access to the Waxell platform — documentation, fleet monitoring, cost tracking, error analysis, and governance.

What It Does​

15 Live Tools — Query your Waxell instance in real-time. Monitor agent health, investigate errors, track LLM costs, review governance policies, and sign up for an account — all from your editor.

8 Documentation Resources — Agent-optimized guides served as MCP resources (waxell://docs/*). Covers the Observe SDK, CLI, integrations, controlplane UI, governance, and Cowork. Work without an API key.

Built-in Signup — Secure device authorization flow. Your agent calls waxell_signup, opens a browser link, and retrieves the API key automatically. No passwords in your terminal.

Per-Client Authentication — Each developer connects with their own API key via the Authorization header. Everyone sees their own data.

Why​

Coding agents like Claude Code, Cursor, and Windsurf can self-serve Waxell adoption:

  1. Connect → point your MCP client at the hosted server, no install needed
  2. Read the docs → understand how to instrument code in minutes
  3. Check the fleet → monitor agent health without opening a browser
  4. Track costs → keep tabs on LLM spending
  5. Review governance → understand what policies are in place

The user barely needs to do anything — the agent discovers, learns, and instruments on its own.

Quick Start​

Add to your .mcp.json (Claude Code):

{
  "mcpServers": {
    "waxell": {
      "type": "sse",
      "url": "https://dev-mcp.waxell.dev/sse",
      "headers": {
        "Authorization": "Bearer wax_sk_your_key_here"
      }
    }
  }
}

Don't have an API key yet? Connect without the headers field — the docs resources work without one. Then ask your agent to call waxell_signup to create an account.
