LangMCP is a read-only MCP server for inspecting LangGraph persistence layers, offering tools, resources, and prompts to debug checkpoints, thread state, and long-term memory directly from editors like Cursor. It provides a safe, profile-based interface for developers working with stateful AI agents, though it is closely tied to LangGraph and not a generic solution.

Target audience: backend devs, ai engineers, devops
