README
Uses Google Calendar API method to fetch upcoming events only.
Test output:

Pre-requisites
Create an app on GCP and get client secret.
- Set up your Google Workspace project and Auth Platform by following Google's documentation
- Download the client secret JSON and keep in the repo base folder as
credentials.json
Run MCP Server
uv venv
uv sync
uv run src/tool.py
Add to Claude Desktop [Windows Setting]
Note: You must have it installed.
Open file in Notepad: %USERPROFILE%\AppData\Roaming\Claude\claude_desktop_config.json
Add the MCP server entry to the JSON:
"gcal-mcp": {
"command": <PATH TO uv.exe>,
"args": [
"--directory",
<PATH TO THE MCP SERVER FOLDER>,
"run",
"src\\tool.py"
]
}
It may look like this finally:
{
"mcpServers": {
"gcal-mcp": {
"command": "%USERPROFILE%\\Miniconda3\\Scripts\\uv.exe",
"args": [
"--directory",
"E:\\Dev\\mcp\\servers\\gcal",
"run",
"src\\tool.py"
]
}
}
}
It should look like this in Claude Desktop

Note
I use Miniconda. Hence the path to UV shows up this way. If you have different setup, you will have to figure out where UV.exe is installed.
