0nMCP

You can run 0nMCP on your machine to orchestrate 252 tools across 17 services using natural language, without building workflows or writing code. It lets you connect services, ask for actions, and have the AI plan and execute multi-step tasks across endpoints while providing an auditable history locally.

How to use

Start by connecting your services using a simple, natural language interface. Once connected, you describe what you want to achieve, and the system plans the steps, calls the appropriate APIs, and returns results. You can perform single-service actions like creating a Stripe customer or posting a message to Slack, or describe multi-step tasks that involve several services.

How to install

Prerequisites: You need Node.js and npm installed on your machine.

# One quick command to start using 0nMCP
npx 0nmcp

If you prefer a global installation, you can install the package globally and then run it.

# Global installation
npm install -g 0nmcp

# Run the MCP server
0nmcp

Configuration and usage notes

You can configure Claude Desktop integration by adding a configuration block that points to the MCP server. The optional API key enables AI-powered multi-step planning.
