Quickstart

1. Create an MCP server:

const server = new MCPServer({
  name: "Example Server",
  version: "1.0.0",
});

1. Add some tools:

server.addTool({
  name: "add",
  description: "Adds two numbers together and returns the result.",
  validator: new ZodValidator(
    z.object({
      a: z.number().describe("First number"),
      b: z.number().describe("Second number"),
    }),
  ),
  handler: async ({ a, b }) => ({
    content: [{ type: "text", text: String(a + b) }],
    isError: false,
  }),
});

1. Wire up your MCP server with a transport:

const transport = new HTTPStreamableTransport();
await transport.connect();

server.withTransport(transport);

1. Handle a Request:

const response = await transport.handleRequest(httpRequest);
