OpenAI Codex
OpenAI's agentic coding tool (CLI, IDE, and cloud) that runs agents and connects to MCP servers and skills.
Last release Sep 8, 2026 · Last commit Sep 2, 2026 · ★ 120,970
Overview
OpenAI Codex is an agentic coding system spanning a CLI, IDE extensions, and a cloud agent. It executes multi-step coding tasks and connects to MCP servers, so onchain agent skills and MCPs (Bankr, CryptoSkills, Base MCP, OpenSea, etc.) can be wired into it. The Codex CLI is open source; the underlying models are proprietary. It is a general-purpose harness rather than an onchain agent.

State changed on 2026-09-01 (unclear → responding).
This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 49 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
