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
AlicenseAqualityAmaintenanceEnables AI assistants to query KumoRFM for predictive analytics on relational data, including graph management, natural language to PQL conversion, and training-free predictions.1233MITWhy this server?
Offers a LangGraph checkpoint saver that persists agent state and memories with AES-256-GCM encrypted storage via the synapse-layer-langgraph integration.
synapse-layerofficial
AlicenseBqualityBmaintenanceMCP-native persistent memory for AI agents. Stores and retrieves encrypted memories with Trust Quotient scoring, cross-agent handover protocol, and immutable audit trail. 13 tools. Remote endpoint available.1313Apache 2.0Why this server?
Integrates with LangGraph, allowing LangGraph agents to retrieve options market data including gamma curves, GEX by strike, and trade setups.
AlicenseAqualityCmaintenanceEnables AI agents to discover and retrieve options market-structure data (GEX, gamma flip levels, dealer positioning, skew, max pain, expected-move levels, options flow, and ranked trade setups) from Trading Volatility's public API via natural language.171MITWhy this server?
Enables LangGraph agents to submit review requests and receive human decisions via the Gatewerk Python SDK.
Why 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).712MITWhy this server?
Integrates with LangGraph to create reactive agents that can perform root cause analysis using RCA-MCP tools.
AlicenseAqualityAmaintenanceEnables causal root cause analysis with 55 tools covering causal graph construction, 13 RCA model families, multi-model consensus, and report generation. Works with 9 LLM providers including Claude, Ollama, and OpenAI.656MITWhy 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.512Apache 2.0Why this server?
Integrates with LangGraph agents to provide trust-scored MCP server discovery and invocation, enabling multi-agent systems to securely access external tools.
AlicenseAqualityDmaintenanceMCP server exposing AgentForge Trust Score audit tools. Query trust, evaluate policies, list trusted servers, recommend with filter.4151MIT
