The project comes with an example tool in src/tools/ExampleTool.ts
. You can add more tools using the CLI:
# Add a new tool mcp add tool my-tool # Example tools you might create: mcp add tool data-processor mcp add tool api-client mcp add tool file-handler
Example tool structure:
import { MCPTool } from "mcp-framework"; import { z } from "zod"; interface MyToolInput { message: string; } class MyTool extends MCPTool { name = "my_tool"; description = "Describes what your tool does"; schema = { message: { type: z.string(), description: "Description of this input parameter", }, }; async execute(input: MyToolInput) { // Your tool logic here return `Processed: ${input.message}`; } } export default MyTool;
