PromptOT MCP: Manage and version LLM prompts from your AI tools

Prompts often start as simple strings in code.

Then the product grows.

You add a better system prompt. Then a guardrail. Then a different version for production. Then a customer-specific variable. Then test cases. Then someone wants to roll back to the version from last week.

At that point, prompts are no longer just text. They become part of the application layer.
