📟 codemcp 📟

codemcp is a small mcp server that exposes agentic coding through codex and claude code. it does not reimplement a coding agent, it forwards normalized MCP tools to the closest official agent interface:

Codex via codex mcp-server
Claude Code via claude -p / claude --resume

installation

install once with composer:

composer require vielhuber/codemcp

then add this to your files:

require __DIR__ . '/vendor/autoload.php';
use vielhuber\codemcp\codemcp;

setup

codemcp reads configuration from the .env in your project root.

CODEMCP_PROVIDER=codex
CODEMCP_WORKDIR=/app
CODEMCP_ALLOW_WRITE=false

MCP_TOKEN=

Claude Code also has claude mcp serve, but that exposes Claude Code's tools to another MCP client. For running Claude Code as the coding agent, codemcp uses print/resume mode.

codemcp expects codex and claude in the local node_modules/.bin directory of the project where the MCP server is started.

usage

$code = codemcp::create();

$result = $code->start(
    prompt: 'Review this project and list the highest-risk bugs.',
    workdir: '/app',
    provider: 'codex'
);

print_r($result);

mcp server

codemcp ships as a standalone MCP server:

vendor/bin/mcp-server.php

available tools:

start(prompt, workdir?, provider?)
continue(session_id, prompt)
status(session_id?)
providers()

write access

Set CODEMCP_ALLOW_WRITE=true when the agent may edit files. Otherwise Codex runs read-only and Claude Code runs in plan mode.
