Codex supports MoleSignal’s Streamable HTTP endpoint and OAuth discovery.
Connect with OAuth 2.1
Authorize the connection
Complete the MoleSignal authorization page in the browser. 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.
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.
