Codex MCP training for engineering teams
Connecting Codex to your repository, docs, and APIs through MCP servers opens real security gaps when no team rules exist. This training covers model context protocol configuration, permission profiles that scope what each MCP server can read or write, allowed workflows, failure handling, and the evidence engineers must attach before any merge. Teams leave able to govern Codex MCP usage safely.
Codex MCP needs repository-level ownership
Codex MCP can expand what the agent can inspect and operate, but the useful training question is narrower: which MCP servers belong in this repository, what context do they expose, and what evidence proves the agent used them correctly.
What the team configures
Participants set up MCP workflows, document TOML and repository configuration, test server availability, and define when Codex should use MCP, ask for permission, or continue with ordinary file inspection.
How it becomes reviewable
The workshop turns MCP setup into a team contract: approved servers, allowed task categories, failure handling, audit evidence, and review prompts that make tool use visible instead of implicit.

Codex CLI 0.121.0 for repo workflows
Codex CLI 0.121.0 repo workflows: named connector owners, a pinned model in AGENTS.md, and PR receipts that survive reviewer handoffs.
Codex CLI 0.132.0: workflows and integrations
Codex CLI 0.132.0 tightens AGENTS.md, MCP, and verification loops for reviewable diffs.
Codex mobile CLI: runs that survive review
A codex mobile cli pattern for running Codex CLI from anywhere: verification latches, model pins, and connector rosters that keep remote runs reviewable.
Codex workflows for mobile handoffs
Codex workflows for mobile handoffs: the repo contract of model pins, connector rosters, done checklists, and slash catalogs that lets agent work change hands.
Codex mobile CLI docs your team can read anywhere
The codex mobile cli question is a docs question: how a team keeps AGENTS.md rules, run notes, and verification transcripts readable away from the desk.
Codex-auto-review: what it catches and misses
Codex-auto-review trials showed Codex catching syntax drift and missing permission drift. The fix is transcript evidence and repo contracts, not more autonomy.
