"LangChain" matching MCP servers:
- AlicenseAqualityBmaintenanceMulti-agent swarm orchestrator for AI workflows. Exposes blackboard read/write, agent dispatch, permission gating (AuthGuardian), token budget enforcement (FederatedBudget), and audit log tools over MCP. Supports 14 AI framework adapters including LangChain, AutoGen, CrewAI, Codex, and A2A — mix any frameworks in one swarm with race-condition-safe shared state.(Traffic light for agents)2457669MIT
- AlicenseAqualityCmaintenanceRAG MCP server for PDFs, YouTube, GitHub repos, and Discord exports. Index documents and query with citations via LangChain and Chroma.52MIT
- AlicenseAqualityDmaintenancePolicy-based governance for AI agent tool calls. YAML policies, approval gates, risk assessment, and audit logging across LangChain, OpenAI, Anthropic, and MCP.515MIT
- AlicenseAqualityCmaintenanceCryptographic proof of consent for AI agents. Sign before you act. Policy engine enforces spending caps, action whitelists, and escalation rules. Independently verifiable by anyone.102Apache 2.0
- AlicenseAqualityDmaintenanceAn MCP server that integrates with LangChain and ChromaDB to provide documentation search for AI libraries and vector database management.4MIT
- FlicenseAqualityDmaintenanceProvides Large Language Models with real-time access to the latest documentation for Python libraries like Langchain, LlamaIndex, and OpenAI, enabling accurate and up-to-date code suggestions.1
- FlicenseAqualityBmaintenanceEnables LLMs to dynamically search, scrape, and query official documentation of libraries like uv, OpenAI, LangChain, and LlamaIndex via Google Serper and Groq.1
- AlicenseAqualityBmaintenanceAI agent identity, permissions, trust scores, and tamper-evident audit trails. 17 MCP tools: register agents (Ed25519 keypairs), check permissions (sub-5ms), emit audit events, verify trust scores (0-100), delegate credentials, ephemeral agents. IETF Internet-Draft filed. Works with LangChain, OpenAI, CrewAI, Stripe ACP. npx @vorim/mcp-server179835MIT
- AlicenseAquality-maintenanceSupplement safety MCP server for AI agents. FDA FAERS signals, CYP450 pathways, 584 compound aliases. Works with Claude Desktop, LangChain, CrewAI.51
- FlicenseAqualityCmaintenanceA search-and-retrieve MCP server that queries official documentation sites for modern libraries like LangChain, OpenAI, and Docker, extracting clean text content using Google Serper API and trafilatura.1
LangSmith MCP Serverofficial
AlicenseAqualityBmaintenanceEnables language models to access LangSmith observability platform features including fetching conversation history, managing prompts, retrieving traces and runs, working with datasets and examples, and analyzing experiments.13131MIT- AlicenseAqualityAmaintenanceThis server allows your AI agents (like Claude, LangChain bots, or custom swarms) to seamlessly execute secure cryptocurrency transactions (USDC) and zero-fee micro-payments straight from their system prompts.182MIT
- AlicenseAqualityDmaintenanceA dual-mode MCP server and CLI agent for AI-powered tasks including weather, news, file management, web scraping, and data processing via LangChain.161MIT
- FlicenseAqualityCmaintenanceReal-time agentic sentinel & breaking-change intelligence server for AI agents (Cursor, Hermes, Claude, LangChain).4
- FlicenseBquality-maintenanceSearches and fetches real-time documentation for libraries like Langchain, OpenAI, and Llama-Index using the Serper API. It allows LLMs to access up-to-date technical information and bypass knowledge cut-off limitations.1
- FlicenseBqualityCmaintenanceAI-powered travel route planning server with budget estimation, packing suggestions, and food recommendations, using LangChain reactive agent with Tongyi Qwen and local deterministic fallback tools.5
- AlicenseBqualityDmaintenanceThis server facilitates the invocation of AI models from providers like Anthropic, OpenAI, and Groq, enabling users to manage and configure large language model interactions seamlessly.213MIT
- AlicenseBqualityAmaintenanceGive any LLM agent a real Android or iPhone. 62 MCP tools: tap, swipe, type, screenshot, screen-tree reading, app launch, camera, TTS, crash reports, batched execution. Android via ADB, iPhone via WebDriverAgent, on-device inference, Docker+KVM emulators. Works with Claude Code, Cursor, LangChain, LlamaIndex, and any MCP client. MIT.66296MIT
- AlicenseBqualityAmaintenanceGovernance runtime for AI agents: a guard tool evaluates risky actions against policy before they execute (block / warn / require human approval), approvals route to a human queue, and every action becomes a replayable decision record with per-action spend tracking. Runs over stdio via npx @dashclaw/mcp-server; works with Claude Code, Codex, LangChain, CrewAI, or any MCP host.68290MIT
