Best LangGraph MCP Servers
LangGraph is a library for building stateful, multi-actor applications with LLMs. It extends LangChain with a flexible graph system to coordinate agent workflows.
Why this server?
Integrates with LangGraph for stateful agent workflows with conservation-law governance, fleet telemetry, and compute budget enforcement.
Why this server?
Allows LangGraph agents to interact with KumoRFM for executing predictive queries, evaluating models, and managing graph metadata.
KumoRFM MCP Serverofficial
AlicenseAqualityCmaintenanceEnables AI assistants to query KumoRFM for predictive analytics on relational data, including graph management, natural language to PQL conversion, and training-free predictions.Last updated1233MITWhy this server?
Provides a callback handler integration to trace LangGraph workflows for observability.
spanlens-mcpofficial
AlicenseAqualityCmaintenanceMCP-native LLM observability. Query your Spanlens traces, stats, cost anomalies, and savings from Cursor, Claude Desktop, or any MCP client. Open source (MIT).Last updated711MITWhy this server?
Provides a drop-in CCSStore adapter for LangGraph that adds read-side coherence and stale-write prevention via MESI protocol.
AlicenseAqualityAmaintenanceCoherence guard for shared files: when two agents write the same file, the stale writer is denied instead of silently overwriting, then reacquires and retries. Single-host, TLA+-verified.Last updated510Apache 2.0Why this server?
Allows integration with LangGraph for building stateful agent workflows using Zoom Search.
AlicenseBqualityAmaintenanceMCP search and evidence tool for AI agents. Rewrites queries, zooms into source domains, and returns sourced answers with metrics.Last updated411MITWhy this server?
Referenced as part of research workflow implementation, though listed as requiring additional validation and re-integration
AlicenseBqualityFmaintenanceThis is a Model Context Protocol (MCP) server adaptation of LangChain Ollama Deep Researcher. It provides the deep research capabilities as MCP tools that can be used within the model context protocol ecosystem, allowing AI assistants to perform in-depth research on topics (locally) via OllamaLast updated316MITWhy this server?
Facilitates execution trace visualization and behavioral diffing for stateful LangGraph agentic workflows.
AlicenseAqualityAmaintenanceMCP server that lets coding agents test AI agents. Create YAML test cases, snapshot golden baselines, check for regressions, and generate visual reports all from inside Claude Code or any MCP-compatible tool. Works with LangGraph, CrewAI, OpenAI, Claude, Mistral, and any HTTP API.Last updated1033124Apache 2.0Why this server?
Provides governance for LangGraph agents, enabling identity-based permissions and human approval for high-risk actions.
AlicenseAqualityDmaintenanceGovernance proxy for MCP servers. Wraps any MCP server with policy evaluation, human approval workflows, and hash-chain audit trails. Supports stdio and Streamable HTTP transports.Last updated1412Apache 2.0Why this server?
Supports LangGraph's create_react_agent interface for building reactive agents that can interact with Razz gaming tools and make real-time wagering decisions.
