📟 codemcp 📟

codemcp exposes agentic coding through the official harnesses of Codex and Claude Code as a small mcp server. runs are asynchronous: they execute detached, results are collected by polling — safe behind any transport timeout.

installation

composer require vielhuber/codemcp

setup

.env in the project root (only for mcps via http):

MCP_TOKEN=

usage

every function below is also exposed 1:1 as an mcp tool of the same name.

$code = codemcp::create();

$session = $code->start(
    prompt: 'Fix the failing tests.',
    workdir: '/app',
    provider: 'claude',
    model: 'claude-opus-4-8',
    effort: 'high'
);

$session = $code->wait(
    session_id: $session['session_id'],
    timeout: 120
);

$session = $code->status(
    session_id: $session['session_id']
);
$code->status();

$session = $code->continue(
    session_id: $session['session_id'],
    prompt: 'Now also fix the linter warnings.'
);

$session = $code->stop(
    session_id: $session['session_id']
);

$providers = $code->providers();

When workdir is omitted, each new session gets a random isolated directory under sys_get_temp_dir()/codemcp/. An explicit directory is created recursively when it does not exist, so new projects start in their final workspace and retain folder continuity. model and effort are required for every new session. Supported effort values are minimal, low, medium, high and xhigh.

tests
