Codex MCP Server

MCP server connecting Claude/Cursor to Codex CLI. Enables code analysis via @ file references, multi-turn conversations, sandboxed edits, and structured change mode.

Features

File Analysis — Reference files with @src/, @package.json syntax
Multi-Turn Sessions — Conversation continuity with workspace isolation
Native Resume — Uses codex resume for context preservation (CLI v0.36.0+)
Local OSS Models — Run with Ollama or LM Studio via localProvider
Web Search — Research capabilities with search: true
Sandbox Mode — Safe code execution with --full-auto
Change Mode — Structured OLD/NEW patch output for refactoring
Brainstorming — SCAMPER, design-thinking, lateral thinking frameworks
Health Diagnostics — CLI version, features, and session monitoring
Cross-Platform — Windows, macOS, Linux fully supported

Quick Start

claude mcp add codex-cli -- npx -y @trishchuk/codex-mcp-tool

Prerequisites: Node.js 18+, Codex CLI installed and authenticated.

Configuration

{
  "mcpServers": {
    "codex-cli": {
      "command": "npx",
      "args": ["-y", "@trishchuk/codex-mcp-tool"]
    }
  }
}

Config locations: macOS: ~/Library/Application Support/Claude/claude_desktop_config.json | Windows: %APPDATA%\Claude\claude_desktop_config.json

Usage Examples

// File analysis
'explain the architecture of @src/';
'analyze @package.json and list dependencies';

// With specific model
'use codex with model gpt-5.5 to analyze @algorithm.py';

// Multi-turn conversations (v1.4.0+)
'ask codex sessionId:"my-project" prompt:"explain @src/"';
'ask codex sessionId:"my-project" prompt:"now add error handling"';

// Brainstorming
'brainstorm ways to optimize CI/CD using SCAMPER method';

// Sandbox mode
'use codex sandbox:true to create and run a Python script';

// Web search
'ask codex search:true prompt:"latest TypeScript 5.7 features"';

// Local OSS model (Ollama)
'ask codex localProvider:"ollama" model:"qwen3:8b" prompt:"explain @src/"';

Tools

Tool	Description
`ask-codex`	Execute Codex CLI with file analysis, models, sessions
`brainstorm`	Generate ideas with SCAMPER, design-thinking, etc.
`list-sessions`	View/delete/clear conversation sessions
`health`	Diagnose CLI installation, version, features
`ping` / `help`	Test connection, show CLI help

Models

By default the model parameter is omitted and Codex CLI applies the default model from your ~/.codex/config.toml (e.g. model = "gpt-5.5"). Pass model only when you need to override the configured default for a single call. Reasoning depth is calibrated per tool:

ask-codex — uses Codex CLI default reasoning (medium). Pass reasoningEffort: "high" / "xhigh" for harder tasks.
brainstorm, do-act, review-changes — default reasoningEffort: "high" (creative ideation, act-check-fix loops, and code review benefit from deeper reasoning).

Model	Use Case
`gpt-5.5`
