Implement an MCP server in TypeScript, Python, or C#/.NET, and register it with a host. Working stdio and HTTP samples verified against the published SDKs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Build an MCP Server
Samples below are minimal but complete: each one runs.
## TypeScript
```bash
npm install @modelcontextprotocol/sdk zod
```
```typescript
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";
const server = new McpServer({ name: "my-mcp-server", version: "1.0.0" });
server.tool(
"list_items",
"List items with pagination. Use before acting on a specific item.",
{ page: z.number().default(1), limit: z.number().max(100).default(20) },
async ({ page, limit }) => {
try {
const items = await api.listItems({ page, limit });
return {
content: [{
type: "text",
text: JSON.stringify({ items, page, hasMore: items.length === limit }),
}],
};
} catch (error) {
return {
content: [{
type: "text",
text: `Error: ${error.message}. Try: check API key, verify endpoint, reduce page size.`,
}],
isError: true,
};
}
},
);
await server.connect(new StdioServerTransport());
```
## Python
```bash
pip install mcp
```

How to install
mdr add fabioc-aloha/alex_skill_mall/mcp-server-build@sha256:fbb32389f2620d4dThe line at the top of this page pins the label git:20260914.0426f9e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
