Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

LangMCP provides a read-only MCP server for inspecting LangGraph agent checkpoints, thread state, and long-term memory, enabling developers to debug stateful agents directly from editors like Cursor. Its profile-based configuration and read-only enforcement fill a specific gap in the AI agent debugging ecosystem.

Target audience: AI/ML engineers, backend devs, agent developers
