Agentic PHP: Implementing Model Context Protocol (MCP) Servers for AI Integration

For the past few years, integrating Artificial Intelligence into PHP applications has largely meant one thing - making HTTP requests to OpenAI, Anthropic, or Google to generate text. We send a prompt string, wait for the inference engine to process it, and we get a string back. This is undeniably useful, but it is entirely passive. The AI is trapped in a box, able only to converse about the data we explicitly spoon-feed it in our prompts.
