LLM to MCP Integration Engine is an open-source framework designed to integrate large language models (LLMs) with various messaging communication platforms (MCPs). It provides adapters for LLM APIs like OpenAI and Anthropic, and connectors for chat platforms such as Slack, Discord, and Telegram. The engine manages session state, enriches context, and routes messages bi-directionally. Its plugin-based architecture enables developers to extend support to new providers and customize business logic, accelerating the deployment of AI agents in production environments.
