Get Joke

Minimal Model Context Protocol (MCP) server (Node.js) that exposes one tool: get_joke.

Setup

npm install

Run

node index.js

Or:

npm start

Test (without Inspector)

This repo includes a tiny SDK-based client that spawns the server over stdio, lists tools, and calls get_joke:

npm run test:mcp

Tool response shape

The get_joke tool returns JSON like:

{
  "joke": "Why do programmers prefer dark mode? Because light attracts bugs."
}

Publish to the MCP Registry (official)

The official MCP Registry stores metadata only, so you must publish the package to npm first.

1. Publish to npm (once):

npm adduser
npm publish --access public

2. Publish metadata to the MCP Registry:

brew install mcp-publisher
mcp-publisher login github
mcp-publisher publish

Notes:

• package.json includes mcpName and server.json uses the same name (required for verification).
• If you change the version, bump it in both package.json and server.json (and republish to npm).
