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.
