# Agent Template | ||
|
||
To keep it simple, at "La Rebelion" we have created server facade that can be used to simplify the creation of agents' tools. This repository contains the source code for the tools that can be registered with the server. | ||
|
||
For more details about the server's facade, visit the [GitHub repository](https://github.com/la-rebelion/mcp-server) or [npm package page](https://www.npmjs.com/package/@la-rebelion/mcp-server). | ||
|
||
We see tools as microservices and containers, must acomplish one task and do it well. This is the reason why we have created this pattern to help you to create your own tools. | ||
|
||
## Steps to Create a New Agent Tool | ||
|
||
```bash | ||
mkdir -p my-agent/src | ||
cd my-agent/ | ||
yarn init -y | ||
yarn add @modelcontextprotocol/sdk zod zod-to-json-schema @la-rebelion/mcp-server | ||
yarn add -D @types/node typescript | ||
``` | ||
|
||
Update the `package.json` file and create a `tsconfig.json` file. | ||
|
||
Implement the tool with the custom logic, and register it in the MCPServer, as simple as that. Check the EchoTool example in the `src` directory. | ||
|
||
Just register the tool with the server and start it. | ||
|
||
```typescript | ||
// src/index.ts | ||
// Create a new instance of the MCPServer | ||
const myServer = new MCPServer('My MCP Server', '1.0.0'); | ||
|
||
async function main() { | ||
// Register tools | ||
myServer.registerTool("echo", new EchoTool()); | ||
await myServer.run(); | ||
} | ||
``` | ||
|
||
