## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.

## MCP tools (3)

### `delegate` (~337 tokens)

Delegate a coding task to OpenAI Codex. Never run codex from the shell — use this tool. Check status before trusting result — a run that spawns then fails returns normally. Keep model, reasoningEffort and fast at their defaults unless the user asks. See the delegate skill.

Input parameters:

- `fast` (boolean): Codex Fast mode; higher credit use.
- `mode` (string): agent implements; plan returns a structured plan; ask answers; review runs native review.
- `model` (string): Codex model id: gpt-5.6-luna, gpt-5.6-sol, gpt-5.6-terra, gpt-5.5, gpt-5.4, gpt-5.4-mini.
- `reasoningEffort` (string): minimal is rejected by every published model; none is accepted though the catalog omits it.
- `resumeThreadId` (string): Thread to continue. Reuse its workspace. Forbidden with review.
- `reviewTarget`: Required in review; forbidden otherwise: uncommitted, base branch, or commit.
- `spec` (string, required): Brief with goal, scope, fixed decisions quoted exactly, and acceptance criteria; reference files instead of pasting code.
- `timeoutMs` (integer): Whole-run cap in ms (default 1h). Mid-turn silence is allowed; startup has a separate 60s first-output deadline.
- `webSearch` (boolean): Codex's built-in web search.
- `workspace` (string, required): Codex's working directory; not confinement. Must already exist — never create one for the call.

### `cancel` (~100 tokens)

Cancel active runs. delegationId selects one (announced in progress before spawn — the only handle if a run wedges at startup), threadId all on its thread, neither all. Waits for settlement; if a process tree survives the kill deadline, it still returns and the delegate result warns. Status: cancelled, nothing-active, or not-found (no active run with this ID).

Input parameters:

- `delegationId` (string)
- `threadId` (string)

### `doctor` (~49 tokens)

Diagnose plugin/CLI/login, recursion, and workspace (default: server cwd). deep adds no-quota help and model-catalog checks.

Input parameters:

- `deep` (boolean)
- `workspace` (string)

## Common questions

### What is the Codex Delegate MCP server?

Codex Delegate is an MCP server listed in the public MCP registry as io.github.andreilungeanu/codex-delegate-mcp. Bridge AI coding hosts to the OpenAI Codex CLI for delegated implementation. This page covers its npm package (codex-delegate-mcp).

### Is the Codex Delegate MCP server safe to use?

Codex Delegate scores 89 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Codex Delegate MCP server expose?

Codex Delegate exposes 3 tools: delegate, cancel, doctor. Their descriptions and schemas cost roughly 486 tokens of context every time the server is loaded.

### Is the Codex Delegate MCP server still maintained?

Codex Delegate is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Codex Delegate MCP server under?

Codex Delegate declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
