🌤️ Weather MCP Tool (Latinum Paywalled Agent Tool)

A minimal Model Context Protocol (MCP) tool that provides real-time weather information for any city. Access to forecasts is paywalled via the Latinum Wallet MCP server, requiring Solana Devnet payment — except for Dublin, which is available for free.

🔧 Developper testing

To install your local build as a CLI for testing with Claude:

git clone https://github.com/Latinum-Agentic-Commerce/latinum-wallet-mcp.git cd weather_mcp python3 -m venv .venv source .venv/bin/activate pip install --upgrade pip setuptools wheel pip install --upgrade --upgrade-strategy eager -r requirements.txt pip install --editable .

Edit your Claude Desktop config:

~/Library/Application Support/Claude/claude_desktop_config.json

{ "mcpServers": { "weather_mcp": { "command": "/Users/{YOUR_USER}/workspace/weather_mcp/.venv/bin/python", "args": [ "/Users/{YOUR_USER}/workspace/weather_mcp/weather_mcp/server_stdio.py" ] } } }

Then restart Claude.

📑 PyPI Publishing

python3 -m venv .venv && source .venv/bin/activate pip install --upgrade pip setuptools wheel pip install -r requirements.txt rm -rf dist/ build/ *.egg-info python3 -m build python3 -m twine upload dist/* pipx upgrade weather-mcp

💳 How It Works

❓ Ask: What's the weather in Paris? → Claude responds instantly.
❌ Ask: What's the weather in London? → Claude gets a 402 and triggers the wallet.
✅ Claude pays using Latinum Wallet and retries.
