Codex supports MoleSignal’s Streamable HTTP endpoint and OAuth discovery.

Connect with OAuth 2.1

1

Register MoleSignal

2

Authorize the connection

Complete the MoleSignal authorization page in the browser.
3

Verify the server

Restart the active Codex task or open a new task so the MCP tool list is refreshed.
Do not add --oauth-resource. MoleSignal already publishes the protected resource through OAuth discovery. Adding the same value again can produce duplicate field resource.

Connect with an API token

Use a personal or Service Account API token for a non-interactive Codex process:
Codex stores the environment-variable name rather than the token value. Make the variable available to the process that launches Codex.

Verify tool discovery

Ask Codex:
Use the MoleSignal MCP server. Search for incident tools and list active incidents. Do not make changes.
The first request should use tool_search, then call_read_tool for a deferred read. See the official Codex MCP documentation.
