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 agents to provide trust-scored MCP server discovery and invocation, enabling multi-agent systems to securely access external tools.
Why this server?
Supports integration with LangGraph for building agent workflows using the server's tools.
AlicenseBquality-maintenance35+ tool MCP server for TCG collectibles and AI agents. Vision AI card grading (PSA/Beckett), Monte Carlo price simulation, AI music generation, local image generation, TTS, RAG memory, and financial analytics — all running 100% locally with zero telemetry.Last updated36Business Source 1.1Why this server?
Fetches official documentation for LangGraph from the web, providing access to agent creation guides and API references.
AlicenseAqualityDmaintenanceEnables managing internal documentation with search and add capabilities, and fetching official documentation from 13+ popular libraries via MCP tools.Last updated69MITWhy this server?
Secures tool node execution and graph states in LangGraph agents.
AlicenseAqualityBmaintenanceLocal zero-trust permission gateway for AI agents. Enforces policy-based tool authorization, human approvals, scoped permissions, and cryptographically verifiable audit logs.Last updated45Apache 2.0Why this server?
Enables LangGraph agents to coordinate access to shared resources with versioned state and conflict detection through MCP integration.
Why this server?
Signs tool calls in LangGraph workflows using LangChain's callback system, allowing cryptographic verification of state graph executions and agent interactions.
AlicenseAqualityAmaintenanceOpen-source MCP server that exposes Signet cryptographic tools over stdio. It provides tools to generate Ed25519 keypairs, sign MCP actions, verify Signet receipts, and compute canonical content hashes for AI agent audit and accountability workflows.Last updated436Apache 2.0Why 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 updated71MITWhy this server?
Allows LangGraph agents to access live company registry data, walk ownership structures across multiple countries, and retrieve statutory filings from government sources.
AlicenseAqualityAmaintenanceUnmodified government company data from 27 registries, live. Cross-border UBO chain walker for AI agents. 60+ tools covering GB, IE, NO, FR, DE, NL, PL, BE, CH, LI, MC, IM, IS, CY, AU, NZ, CA, TW, HK, MY, FI, CZ, ES, IT, KR, US — raw upstream fields preserved, no LLM extraction.Last updated104Apache 2.0Why this server?
Referenced as part of research workflow implementation, though listed as requiring additional validation and re-integration
AlicenseBqualityCmaintenanceThis 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 updated316MIT
