mcp-week-day

A small MCP server built with FastMCP. It exposes a single tool, day_in_week, which returns the current day of the week — "Monday", "Tuesday", …

Requirements

• Python 3.10+

Related MCP server: mcp-local-gateway

Setup & run from scratch

Using uv (recommended)

# Run the server
uv run mcp-week-day

First run might take some time as a virtual environment will be created and dependencies will be installed into it.

Using pip

# Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate        # on Windows: .venv\Scripts\activate

# Install the project (+ dependencies)
pip install -e .

# Run the server
mcp-week-day

The server communicates over stdio using the MCP protocol.

Register with an MCP client

Add an entry like this to your client's MCP configuration:

{
  "mcpServers": {
    "week-day": {
      "command": "uv",
      "args": ["run", "mcp-week-day"]
    }
  }
}

If you installed with pip into an activated environment, you can instead use "command": "mcp-week-day" with no args.
