Codex CLI

Codex reads MCP servers from config.toml and sends a bearer from an env variable.

API key

Setup

1
Export the key in your shell profile.
Shell
```
export ZOMLER_API_KEY="zk_live_…"
```

Add the server to ~/.codex/config.toml.

config.toml

[mcp_servers.zomler]
url = "https://api.zomler.com/mcp"
bearer_token_env_var = "ZOMLER_API_KEY"

Start codex; the Zomler tools are listed under /mcp.

What you get

One tool per platform, plus capabilities and check_balance, at https://api.zomler.com/mcp. Every answer is the envelope: what was measured, when, what was left out and why, and what it cost. Fresh fetches spend credits; anything already held is free.

Keys are created under API keys in the dashboard, where each one's calls and spend are listed. Revoking a key stops this client on its next call. The same key also calls the REST API.
