MCP Travel Desk is a minimal MCP client and server demo for handling travel requests using Claude Desktop.
MCP Travel Desk — A Minimal MCP Client & Server Demo
This is a simple repository that shows the process of building an MCP server and using Claude Desktop as a client. I have shown here a simple Travel Desk system to handle employee travel requests, approvals, and history tracking — all accessible directly from Claude. One can modify the contents of this repo to develop specific MCP use cases.
Setup Instructions
1. Install Claude Desktop
Download and install Claude Desktop from Anthropic. This acts as your MCP client.
2. Install MCP Python SDK
pip install mcp
3. Install uv (Python Package Manager)
pip install uv
On macOS, if this fails:
brew install uv
4. Initialize MCP Server
uv init
5. Create main.py
append the main.py code in the repo
6. Install the Server into Claude
uv run mcp install main.py
This will:
Create a virtual environment (.venv) Add your server to Claude config Output logs like:
Added server 'TravelDesk' to Claude config
Successfully installed TravelDesk in Claude app
7. macOS Troubleshooting
If the server doesn't start in Claude: Run:
brew install uv
Restart Claude Desktop Go to Claude → Developer Settings and ensure the server is Running
8. Use Claude as MCP Client
Claude reads the MCP config from .mcp/claude.json.
9. Tools Appear in Claude UI
Once installed, the following tools will be available inside Claude:
submit_travel_request get_travel_history approved_trips_count greeting://{name}
10. Ask Queries via Claude
Try asking: Submit a travel request for E001 to Paris from 2025-01-01 to 2025-01-05 How many approved trips does E002 have? Get travel history for E001 greeting://Chaitanya
