Summary
This server lets Claude start and manage long-running processes like dev servers, Docker Compose stacks, or test watchers, then check their stdout and stderr to debug issues autonomously. It uses a whitelist pattern for security: the LLM must ask permission once to allow a specific command in a specific directory, then can restart or monitor that process freely without repeated confirmations. Tools include start-process, delete-process, restart-process, and log retrieval commands. Processes clean up automatically when your Claude session ends. Reach for this when you want Claude to spin up services, run watchers, and iterate on fixes based on their output without manual intervention.

A Model Context Protocol (MCP) server for process management.
Supported features
- Secure and automatable process creation
- Cleanup created processes automatically on termination (e.g. exiting claude code)
- Common process management features supported, restarting, deleting, checking status or retreving stdout/stderr of processes
Using these features, LLMs start processes like development servers, docker-compose, or test watchers and check their outputs to fix bugs automatically.
Installation
npm i -D procm-mcp
.mcp.json
{
"mcpServers": {
"procm-mcp": {
"command": "node",
"args": ["./node_modules/procm-mcp/build/index.js"],
"env": {}
}
}
}
Secure process creation
You can permit LLMs to use start-process tool without confirmation, because procm-mcp only allow whitelisted process creations.
LLMs will ask you to use allow-start-process tool to add specific process creation to the whitelist.
Once you allow a process creation, you don't have to confirming it anymore as long as the command and the working directory are the same.
I call it "allow-x pattern", which can balances security and usability in MCP.
Warning: Do not permit LLMs to use allow-start-process without confirmation.That means "Do anything you want to".
