"Updated documentation for LangChain, Langraph, Node.js, Express, and FastAI frameworks" matching MCP servers:

Review and rewrite LangChain, LlamaIndex, Ollama, and XRPL code against current APIs, plus runnable examples, import lookup, and XRPL tx skeletons that never submit. Live docs included. $0.001 USDC on Base or 1000 drops XRP.

Provides real-time access to official LangChain documentation, API references, and GitHub code examples to assist in LangChain-based development. It enables LLMs to search for tutorials, version info, and detailed class specifications directly from live sources.

Provides semantic search across the entire LangChain ecosystem, including documentation and source code for LangChain, LangGraph, LangSmith, and DeepAgents.

A read-only Model Context Protocol server for Hyperliquid that exposes over 30 tools to query public market data and user state via the Hyperliquid Info API, without requiring a private key.

MCP server for the eXpress corporate messenger, enabling AI agents to list chats, search contacts, send messages, and wait for incoming messages with end-to-end encryption.

Enables macOS agents to read eXpress chats and threads, search contacts, send messages and attachments, and download verified files through MCP, while a Keychain-backed session broker manages authentication.

Enables AI assistants to register, monitor, and query express delivery tracking numbers, with automatic background polling and status-change notifications returned through tool results.

Enables full-text search and paginated retrieval of indexed documentation (PDFs, Markdown, text) through MCP tools, with filtering by category and file.

Enables reading and searching a user's eXpress chats and message history locally, with optional confirmed sending of text messages.

A server that enables Claude to search and access documentation from popular libraries like LangChain, LlamaIndex, and OpenAI directly within conversations.

Enables Brave Search and web content fetching via MCP, and integrates as LangChain tools for AI agents.

Enables querying Node.js API documentation, including searching for modules and listing all available modules with their methods.

Enables scanning Express.js route surfaces for inventory and audit, classifying routes as public/authenticated.

Enables Adobe Express add-on developers to scaffold projects, access code examples, query SDK documentation, and get implementation guidance for building Adobe Express add-ons.

A utility that integrates Model Context Protocol (MCP) into Express applications, offering both stateful session management and stateless request handling options.

Enables existing Express routers to be exposed as MCP tools, dispatching tool calls through the Express middleware stack in-process without a network hop.

Expose any LangChain chain, agent, or tool as an MCP server — schema-aware tool registration, tool-call tracing, structured output validation. Bridges LangChain into Claude/Cursor/Windsurf. Curated by Archimedes Market with a verified Trust Report.

Exposes LangChain agent capabilities through the Model Context Protocol, enabling multi-step reasoning tasks with ReAct pattern execution via a production-ready FastAPI service deployed on Google Cloud Run.

An MCP server that demonstrates modern MCP spec features including elicitation (interactive confirm dialogs), signed request state, and cache hints, with a deploy tool requiring confirmation. It runs as both a Node server and a Cloudflare Worker, supporting stateless per-request handling.

Automatically analyzes Python codebases and generates professional documentation including README, API docs, and setup guides.
