Getting Started

LazyMCP is a Model Context Protocol (MCP) server that provides AI tools for mathematical calculations, network analysis, and weather information. Use LazyMCP to enhance your AI assistant with powerful computational capabilities.

Available Tools

LazyMCP provides 5 tools across 3 categories:

🌤️ Weather

  • get_weather - Current weather conditions
  • get_weather_forecast - 5-day weather forecast with 3-hour intervals

🌐 Network

  • get_ip - Get client IP address
  • get_ip_data - Get detailed IP geolocation data

🧮 Calculator

  • calculate - Mathematical expression evaluation with support for basic arithmetic, trigonometry, and advanced functions

Setup Instructions

LazyMCP is available as a public service at https://lazymcp.ai/mcp. Follow the instructions below for your AI tool:

Claude Code (claude.ai/code)

Use the Claude MCP command to add LazyMCP:

claude mcp add --transport http lazymcp https://lazymcp.ai/mcp

This command will:

  • Add LazyMCP as an MCP server named "lazymcp"
  • Configure HTTP transport for the connection
  • Connect to the public LazyMCP service

Verify the connection by checking that all 5 tools appear in your Claude Code session.

Claude Desktop App

  1. Open the Claude Desktop application
  2. Go to Settings → Connectors
  3. Click Add custom connector
  4. Fill out the connector form:
    • Name: LazyMCP
    • Remote MCP: https://lazymcp.ai/mcp
  5. Click Add to save the connector
  6. Verify the LazyMCP connector appears as "CUSTOM" in your connectors list
  7. Confirm all 5 tools are available in your conversations

OpenCode

Edit your OpenCode configuration file at ~/.config/opencode/opencode.json and add the MCP server:

{
  "mcp": {
    "lazymcp": {
      "type": "remote",
      "url": "https://lazymcp.ai/mcp",
      "enabled": true,
      "headers": {}
    }
  }
}

After saving the configuration:

  1. Restart OpenCode to load the MCP server
  2. Verify all 5 LazyMCP tools are available in your workspace

Other MCP-Compatible Clients

For any MCP-compatible AI tool, use these connection parameters:

  • Server URL: https://lazymcp.ai/mcp
  • Transport Protocol: Streamable HTTP
  • Authentication: None required (public service)

Verifying Your Setup

Once connected, test LazyMCP with a simple calculation:

Ask your AI assistant: "Calculate the square root of 144"

You should see the AI use the calculate tool and return: 12

You can also test other tools:

  • "What's the weather like in London?" (uses get_weather)
  • "What's my IP address?" (uses get_ip)

Using LazyMCP Tools

Weather Examples

  • "What's the current weather?"
  • "Get weather forecast for New York"
  • "Show me the 5-day forecast for coordinates 51.5074,-0.1278"

Network Examples

  • "What's my current IP address?"
  • "Get geolocation data for IP 8.8.8.8"
  • "Where is my internet connection located?"

Calculator Examples

  • "Calculate sin(π/4) + cos(π/4)"
  • "What's 2^10?"
  • "Solve: sqrt(16) * log(100)"

Troubleshooting

Common Issues

Tools not appearing: Verify the server URL is exactly https://lazymcp.ai/mcp with HTTPS

Connection failed: Check your internet connection and ensure your AI client supports MCP

Weather tools not working: The public LazyMCP service includes weather functionality - no additional setup needed

Calculation errors: Ensure mathematical expressions use supported functions and syntax

Getting Help

If you encounter issues:

  1. Check the Configuration Guide for detailed troubleshooting
  2. Review tool-specific documentation in the Tools section
  3. Report bugs on GitHub Issues
