# Use SEC EDGAR data in Codex CLI

Canonical: https://sec-api.dev/use-with-codex

> Add sec-api.dev as a remote MCP server in Codex CLI.

1. Create a free sec-api.dev account and copy an API key.
2. Export SEC_API_KEY in the shell that runs Codex.
3. Add the block below to config.toml and restart Codex; run /mcp to list the tools.

~/.codex/config.toml:

```toml
[mcp_servers.sec-api]
url = "https://sec-api.dev/api/mcp"
bearer_token_env_var = "SEC_API_KEY"
```

bearer_token_env_var makes Codex send Authorization: Bearer with the variable’s value.
