MCP Server Builder

Build production-ready MCP servers with tools, resources, prompts, and interactive widgets using mcp-use.

Before You Code

Decompose user requests into tools, widgets, and resources. Decide what needs UI vs text.

Read design-and-architecture.md: when planning what to build, deciding tool vs widget, or designing UX flows.

Implementation

Tools, resources, prompts → tools-and-resources.md: when writing server-side
```
server.tool()
```
,
```
server.resource()
```
,
```
server.prompt()
```
code
Visual widgets (React TSX) → widgets.md: when creating interactive UI widgets in
```
resources/
```
folder
Response helper API → response-helpers.md: when choosing how to format tool/resource return values
URI template patterns → resource-templates.md: when defining parameterized resources

Quick Reference

typescript

import { MCPServer, text, object, markdown, html, image, widget, error } from "mcp-use/server";
import { z } from "zod";

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

// Tool
server.tool(
  { name: "my-tool", description: "...", schema: z.object({ param: z.string().describe("...") }) },
  async ({ param }) => text("result")
);

// Resource
server.resource(
  { uri: "config://settings", name: "Settings", mimeType: "application/json" },
  async () => object({ key: "value" })
);

// Prompt
server.prompt(
  { name: "my-prompt", description: "...", schema: z.object({ topic: z.string() }) },
  async ({ topic }) => text(`Write about ${topic}`)
);
