Once connected, the assistant can call these 7 tools directly:
Description — Echoes the input message, prefixed with "Hello "Method — tools/invokeParameters — { name: 'echo', parameters: { message: string } }Returns — { content: [{ type: 'text', text: 'Hello {message}' }] } (e.g., { content: [{ type: 'text', text: 'Hello test' }] })Resources — The Resources tool exposed by this serverTools — The Tools tool exposed by this serverPrompts — The Prompts tool exposed by this serverThe server is distributed via npm as mcp-hello-world, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. MCP Hello World sits in that group, and the shape of its toolset — Description, Method, Parameters among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
