MCP FastMCP Greet Server

Minimal MCP server (FastMCP 3 beta) with a greet tool and a UI resource that returns https://example.com as text/uri-list.

Setup

Create and activate a virtualenv, then install dependencies:

python3 -m venv .venv
source .venv/bin/activate   # On Windows: .venv\Scripts\activate
pip install -r requirements.txt

Run

Stdio (default):

python server.py

Or with the FastMCP CLI:

fastmcp run server.py:mcp

HTTP (optional):

fastmcp run server.py:mcp --transport http --port 8000

Usage

• The greet tool accepts a name and returns a greeting. MCP Apps–capable clients will also show the linked UI resource.
• The UI resource ui://greet/view.html returns MIME type text/uri-list with https://example.com; the client may show or open it.
