Developed by Anthropic, the Model Context Protocol (MCP) is an open protocol that standardizes how applications provide context to LLMs. It is particularly helpful when building agents and complex workflows on top of LLMs.
Think of MCP like a USB-C port for AI applications. Just as USB-C provides a standardized way to connect your devices to various peripherals and accessories, MCP provides a standardized way to connect AI models to different data sources and tools.

Troubleshooting

​
Authentication Format

Important: The new version (2.x) of the Linkup MCP server uses a different authentication format: ✅ Correct (v2.x): 
{
  "args": ["-y", "linkup-mcp-server", "apiKey=YOUR_API_KEY"]
}
❌ Old format (v1.x): 
{
  "env": {
    "LINKUP_API_KEY": "YOUR_API_KEY"
  }
}
If you were using v1.x, please update your configuration to the new format.
