API & MCP server

Everything below is real and live today: the same API LazyRelay's own dashboard runs on. Already have an account? The same docs live inside your dashboard's API Keys tab, with no need to sign back in.

Authentication

Generate a key from your dashboard: More → API Keys → Create key. The raw key is shown once, copy it immediately. Send it as a bearer token on every request:

Authorization: Bearer lzr_live_your_key_here

Each key acts as your account. Treat it like a password. Creating or revoking keys always requires signing in to the dashboard directly; a key can never be used to mint or revoke other keys, so a leaked key can't lock you out.

Using this from an AI agent: the MCP server

If you're connecting an AI agent (Claude Desktop, Claude Code, Cursor, or anything else that speaks MCP) rather than writing HTTP calls by hand, use LazyRelay's own MCP server instead of calling the API directly. It wraps every endpoint above as a real tool the agent can call.

{
  "mcpServers": {
    "lazyrelay": {
      "command": "npx",
      "args": ["-y", "@lazyrelay/mcp-server"],
      "env": { "LAZYRELAY_API_KEY": "lzr_live_your_key_here" }
    }
  }
}

This runs locally on your own machine using your own API key, there's nothing to host. See the package README for the full tool list.

No install: the hosted MCP server

Prefer not to install anything, or connecting from claude.ai rather than a desktop app? LazyRelay also runs a hosted MCP server. Instead of an API key, you sign in with your LazyRelay account the first time you connect. Same 6 tools, same account, nothing to run locally.

https://lazyrelaylazyrelay-backend.onrender.com/mcp

In Claude, go to Settings → Connectors → Add connector, choose Remote, and paste the URL above. You'll be asked to sign in and approve access, the same way you'd approve any other app. For MCP clients that use a config file instead:

{
  "mcpServers": {
    "lazyrelay": {
      "url": "https://lazyrelaylazyrelay-backend.onrender.com/mcp"
    }
  }
}

To stop a connected app from accessing your account, remove it from wherever you connected it (for example, your AI tool's connector settings).
