Codex

Prerequisites and availability

You need a Codex installation with remote MCP and OAuth support, and a Stratifyre account. Remote MCP plus portable skills is the supported baseline. Native Codex packaging is optional and is available only when the published compatibility information records a passing pinned smoke test.

Release/evidence pin: @stratifyre/[email protected], Codex CLI 0.152.0 fixture, fallback path only; client smoke evidence not recorded.

Connect and verify

Add and authorize the production server:

codex mcp add stratifyre --url https://app.stratifyre.com/mcp
codex mcp login stratifyre
codex mcp list

Complete OAuth in the browser opened by Codex. Confirm the server appears in the list; use only Codex-managed configuration and do not commit OAuth material.

For first use, ask Codex to discover the live manifest, inspect available status and scopes, and read existing strategies. Explicitly prohibit creates, updates, deletion, and backtests for this first task.

Create, backtest, and limits

After the read-only check, ask Codex to draft the complete strategy_create payload, show it for approval, create it once, poll strategy_create_status, and call strategy_get. For a backtest, review and approve the complete backtest_start payload, poll backtest_status, and inspect the result. Resolve named instruments in Stratifyre or provide canonical IDs; the current MCP manifest has no direct market-data search tool. Capabilities and limits come from the live server, OAuth scopes, entitlements, job limits, and your Codex workspace.

Approval in the conversation is agent guidance, not server enforcement. Independent candidates can partially fail; do not imply batch atomicity or retry without review.

Update, remove, or use the portable fallback

Update with the next versioned fallback bundle and replace both skill directories together. Remove the stratifyre entry with codex mcp remove stratifyre, delete copied skills, and revoke the OAuth authorization in Stratifyre if desired. Native Codex packaging is not published because its pinned smoke test is not run.

Documentation basis: OpenAI Codex MCP documentation, https://developers.openai.com/codex/mcp/, checked 2026-09-01; the named client fixture is not yet smoke-tested.
