FAQ
What is MCP and why do I need it?
MCP (Model Context Protocol) is an open standard by Anthropic that lets AI models use external tools and data sources. It enables Claude to interact with your databases, APIs, and services in real-time, making your AI assistant much more powerful.
Do you work with GPT or only Claude?
I work with both Claude API and OpenAI GPT. I can also integrate open-source models like Llama or Mistral. My specialty is Claude and MCP, but I adapt to your project needs.
Do I need to provide my own API keys?
Yes, you will need your own Anthropic or OpenAI API keys for production use. I will help you set up the accounts and configure everything securely. During development, I can use test keys.
