"LangGraph" matching MCP servers:

An AI-powered server that analyzes system log files to identify errors/warnings and recommend fixes using FastMCP, LangGraph ReAct agents, and Anthropic Claude.

Universal verifiable recovery for long-running AI agents with semantic checkpoints, idempotent action ledger and hash chained log as a deny by default MCP server. Framework agnostic with adapters for LangGraph, LangChain and OpenAI plus gateway and OTel.

A defensive MCP server for Claude Desktop / any MCP client — the blue-team counterpart to offensive tooling. 123 tools + 4 resources across Wazuh SIEM, multi-provider threat intelligence, MITRE-driven 3-Sum APT correlation, attack graphing, LangGraph investigation workflows, and host forensics. Read-only by default.

A read-only MCP server exposing GPON access-network tools for inventory, status, configuration diff, and alarms, enabling a LangGraph agent to audit ONT provisioning against a golden baseline. It runs against a simulated network and enforces read-only constraints at multiple levels.
