Connect Codex

Add the System Atlas MCP server to Codex so it can read the atlas and upload your company.

  1. Make a key

    Create a key in Settings and keep it at hand. Replace sa_… below with it, or use /connect, which fills it in for you.

  2. Add the config

    Add to ~/.codex/config.toml.

    [mcp_servers.systematlas]
url = "https://systematlas.org/mcp"
http_headers = { "Authorization" = "Bearer sa_…" }

  3. Reload and check

    Restart Codex or reload its tools, then ask:

    List the System Atlas tools you have, then call list_industries.

    You should see the System Atlas tools and a list of industries.

Next

Hand Codex the mapping prompt (/agent-prompt.md) and follow Map your company with your agent.

Troubleshooting
A 401 means the key is missing, revoked or mistyped (keep the Bearer prefix). Tools missing after a reload: check the URL ends in /mcp and is https://systematlas.org.
