Tools

Tool	Description
`codex`	AI coding assistant with session support, model selection, and structured output metadata
`review`	AI-powered code review for uncommitted changes, branches, or commits
`websearch`	Web search using Codex CLI with customizable result count and search depth
`listSessions`	View active conversation sessions
`ping`	Test server connection
`help`	Get Codex CLI help

Examples

Code analysis:

Use codex to analyze this authentication logic for security issues

Multi-turn conversations:

Use codex with sessionId "refactor" to analyze this module
Use codex with sessionId "refactor" to implement your suggestions

Passing a sessionId creates the session on first use, so listSessions will show it (for this server instance) and subsequent calls can resume context.

Code review:

Use review with base "main" to check my PR changes
Use review with uncommitted true to review my local changes

Advanced options:

Use codex with model "o3" and reasoningEffort "high" for complex analysis
Use codex with fullAuto true and sandbox "workspace-write" for automated tasks
Use codex with callbackUri "http://localhost:1234/callback" for static callbacks
Use codex to return structuredContent with threadId metadata when available

Web search:

Use websearch with query "TypeScript 5.8 new features"
Use websearch with query "Rust vs Go performance 2025" and numResults 15
Use websearch with query "React Server Components" and searchDepth "full"

Requirements

Codex CLI v0.75.0+ — Install with npm i -g @openai/codex or brew install codex
OpenAI API key — Run codex login --api-key "your-key" to authenticate

Codex 0.87 Compatibility

Thread ID + structured output: When Codex CLI emits threadId, this server returns it in content metadata and structuredContent, and advertises an outputSchema for structured responses.
