 # Agentic Developer MCP This project wraps OpenAI's Codex CLI as an MCP (Model Context Protocol) server, making it accessible through the TeaBranch/open-responses-server middleware. This engine may be replaced with OpenCode or Amazon Strands ## Requirements - Node 22 (`nvm install 22.15.1 | nvm use 22.15.1`) required for Codex ## Overview The setup consists of three main components: 1. **Codex CLI**: OpenAI's command-line interface for interacting with Codex. 2. **MCP Wrapper Server**: A Node.js Express server that forwards MCP requests to Codex CLI and formats responses as MCP. 3. **open-responses-server**: A middleware service that provides Responses API compatibility and MCP support. ## Installation ### Using Docker (Recommended) ```bash # Clone this repository git clone https://github.com/yourusername/codex-mcp-wrapper.git cd codex-mcp-wrapper # Start the services ./start.sh ``` This will start: - Codex MCP wrapper on port 8080 - open-responses-server on port 3000 ### Manual Installation ```bash # Install dependencies npm install # Install Codex CLI globally npm install -g @openai/codex # Start the MCP server node mcp-server.js # Install the package in development mode pip install -e . ``` ## Usage You can run the MCP server using either stdio or SSE transport: ```bash # Using stdio (default) python -m mcp_server # Using SSE on a specific port python -m mcp_server --transport sse --port 8000 ``` ## Tool Documentation ### run_codex Clones a repository, checks out a specific branch (optional), navigates to a specific folder (optional), and runs Codex with the given request. #### Parameters - `repository` (required): Git repository URL - `branch` (optional): Git branch to checkout - `folder` (optional): Folder within the repository to focus on - `request` (required): Codex request/prompt to run #### Example ```json { "repository": "https://github.com/username/repo.git", "branch": "main", "folder": "src", "request": "Analyze this code and suggest improvements" } ``` ### clone_and_write_prompt Clones a repository, reads the system prompt from `.agent/system.md`, parses `modelId` from `.agent/agent.json`, writes the request to a `.prompt` file, and invokes the Codex CLI with the extracted model. #### Parameters - `repository` (required): Git repository URL - `request` (required): Prompt text to run through Codex - `folder` (optional, default `/`): Subfolder within the repository to operate in #### Example ```json { "repository": "https://github.com/username/repo.git", "folder": "src", "request": "Analyze this code and suggest improvements" } ``` ### MCPS Configuration Place a `mcps.json` file under the `.agent/` directory to register available MCP tools. Codex will load this configuration automatically. Example `.agent/mcps.json`: ```json { "mcpServers": { "agentic-developer-mcp": { "url": "..." } } } ``` ## Development This project uses the MCP Python SDK to implement an MCP server. The primary implementation is in `mcp_server/server.py`. ## License MIT
