time-tracking-google-calendar-mcp

A Model Context Protocol (MCP) for managing a Google calendar with a set of non-overlapping events representing one person's time

Setup

Create and activate a virtual environment, then install dependencies.

macOS/Linux:

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Windows (PowerShell):

python -m venv .venv
.venv\Scripts\Activate.ps1
pip install -r requirements.txt

Related MCP server: mcp-google-calendar

Running the server

With the virtual environment activated, run the server directly:

python server.py

Or launch it with the MCP Inspector for interactive testing:

mcp dev server.py

mcp dev requires two tools outside the Python virtual environment: Node.js/npx (to launch the Inspector UI itself) and uv (the Inspector uses it to run the server in an isolated, on-the-fly environment). Neither is something pip/venv can provide — a venv only manages Python packages already on your machine, not other language runtimes or tools.

Installing Node.js (provides npx):

• macOS: brew install node

• Windows: winget install OpenJS.NodeJS.LTS (or download the installer from nodejs.org)

• Linux: use your distro's package manager (e.g. sudo apt install nodejs npm) or install via nvm

Installing uv:

• macOS/Linux: curl -LsSf https://astral.sh/uv/install.sh | sh

• Windows: winget install astral-sh.uv (or powershell -c "irm https://astral.sh/uv/install.ps1 | iex")

After installing, restart your terminal and verify with:

npx --version
uv --version

If you only need to run the server (not the Inspector), python server.py works without Node.js or uv.

server.py currently contains a minimal scaffold (an add tool and a greeting resource) from the MCP Python SDK quickstart, ready to be extended with Google Calendar-backed tools.
