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?
Enables LangGraph agents to use structured graph queries for dependency analysis, prerequisite chains, and blast radius computations as part of agent workflows.
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).Last updated79MITWhy 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 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?
Supports LangGraph agents by providing MCP tools for scraping, minification, semantic caching, and free utilities, allowing integration into graph-based agent workflows.
AlicenseAqualityCmaintenanceProvides several x402 utilities to reduce token usage, web scraping, and chron jobsLast updated7165MITWhy this server?
Provides tools for building LangGraph-based agent workflows that include escrow creation, delivery, and dispute resolution using Arbitova.
AlicenseAqualityCmaintenanceNon-custodial on-chain escrow + AI arbitration for agent-to-agent USDC payments on Base. Seven tools wrap a verified EscrowV1 contract — create, deliver, confirm, dispute, resolve — with read-only introspection if no wallet key is provided.Last updated72MITWhy this server?
Provides optional integrations for LangChain/LangGraph to persist and share artifacts from agent runs.
AlicenseAqualityAmaintenanceThe artifact store for AI agents. Every output your agents produce — persisted, retrievable, shareable. Across runs, sessions, and tools. Session/agent metadata, content-hash dedup, and expiring share links; available on npm (@artifacta-mcp/mcp) and PyPI (artifacta-mcp).Last updated81MIT
