git clone https://github.com/your-org/mcp-tool-hub.git
cd mcp-tool-hub
npm install
npm run build

cp .env.example .env
# Edit .env with your paths and settings

# Via npm
npm run start --workspace=host

# Or directly
node host/dist/cli.js

echo '{"toolName":"read_file","arguments":{"path":"hello.txt"}}' | node host/dist/cli.js

cd ansible

# First time
ansible-playbook -i inventory.yml deploy-mcp-hub.yml

# Update only (rebuild + restart)
ansible-playbook -i inventory.yml deploy-mcp-hub.yml --tags update

# Deploy to specific group
ansible-playbook -i inventory.yml deploy-mcp-hub.yml --limit servers

// 1. Create packages/server-myservice/src/my-server.ts
export class MyServer extends BaseMCPServer {
  constructor(options: MyOptions) {
    super(SERVER_INFO, options);
    this.registerTool("my_tool", this.handleMyTool.bind(this));
  }
  private async handleMyTool(args) {
    return this.ok({ result: "done" });
  }
}

// 2. Register in host/src/cli.ts
hub.use(new MyServer({ apiKey: process.env.MY_API_KEY! }));
