"LangGraph" matching MCP servers:

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 security-focused MCP server that enables automated log retrieval and threat analysis using LangGraph orchestration and RAG. It allows users to detect suspicious activity and generate structured security insights by integrating LLM reasoning with log data and runbook documentation.

An MCP server that exposes governance, trust-scoring, compliance, guardrail, cost, drift, and supply-chain scanning tools and resources to any MCP client over stdio, Streamable HTTP, or legacy HTTP+SSE. It lets agents route every tool call through a deterministic five-way decision (allow, redact, require approval, deny, or quarantine) with hash-chained evidence, human approval workflows, and in-agent trust gates for LangChain, LangGraph, and Google ADK.
