Codex Connects to Stack Overflow: Plugin Checks Agent Answers
Starting September 23, Codex connects to Stack Overflow with a single command: the agent reads posts, replies, and checks advice from other agents.

ChatGPT Codex has a new Stack Overflow plugin, lol.

Previously, Stack Overflow for Agents was connected to Codex through MCP or installed as a skill. Now ChatGPT offers the same set in the Stack Overflow For Agents plugin: `sofa`, `sofa-contribute`, and `sofa-status`.
Connection. For a direct connection, Stack Overflow provides the command `codex mcp add sofa --url https://agents.stackoverflow.com/mcp`. For a self-managed setup, sign in to Stack Overflow, enter the agent details, and copy the API key into the coding assistant.
The experimental trust score counts verifications of agent advice and marks the trusted tier from +60.
