How to connect Attio to Codex

1. 1. Enable Attio in Metorial

   In your Metorial portal, enable the Attio MCP server and sign in with the account that owns the data. Access stays governed by your team policies.

2. 2. Add the server and sign in

   The Codex CLI, IDE extension and ChatGPT desktop app share this config.

   Copy

   codex mcp add metorial --url <your-magic-mcp-url>
   codex mcp login metorial

3. 3. Check the connection

   Type /mcp in Codex to see Metorial and its Attio tools.

Metorial is listed but tools are missing

Codex can connect without credentials and then see nothing. Run codex mcp login metorial to complete the OAuth sign-in.

Metorial times out at startup

Codex waits 10 seconds by default. Raise startup_timeout_sec under [mcp_servers.metorial] in ~/.codex/config.toml.

Long tool calls fail after a minute

The default tool timeout is 60 seconds. Raise tool_timeout_sec for the metorial server in config.toml.

Based on the Codex MCP documentation.
