MCP servers

A CLI and library that converts a codebase into a single LLM prompt, with prompt templating, token counting, and a matching Python SDK and MCP server.

• MCP servers
• CLI tools

An MCP server that lets agents and LLMs automate native iOS and Android apps on simulators, emulators or real devices through one platform-agnostic interface.

• MCP servers
• Testing

A free, open-source remote MCP server that turns any GitHub repository or GitHub Pages site into a documentation hub AI coding assistants can query.

• MCP servers

A hosted Model Context Protocol server that lets AI agents run thousands of Apify scrapers, crawlers and automation tools to extract data from any website.

• MCP servers
• Browser automation

A Go implementation of the Model Context Protocol, providing a high-level interface for building MCP servers with resources, tools and prompts.

• MCP servers

The specification, protocol schema and official documentation for the Model Context Protocol (MCP), with the schema defined in TypeScript and also published as JSON Schema.

• MCP servers

A suite of specialized, open-source Model Context Protocol servers for working with AWS services, covering documentation lookup, infrastructure and deployment, data and databases, and developer tooling.

• MCP servers

An MCP server that gives an AI assistant terminal control, filesystem search and diff-based file editing, plus in-memory code execution and support for Excel, PDF and Word files.

• MCP servers

A TypeScript framework for building, testing and shipping MCP servers and MCP apps for ChatGPT and Claude, with typed schemas, built-in views and an inspector.

• MCP servers

A developer tool for inspecting Model Context Protocol (MCP) servers through a web UI, a scriptable CLI, or an interactive terminal UI, all through one binary.

• MCP servers
• Debugging

An open-source AI observability and evaluation platform for tracing, evaluating and troubleshooting LLM applications, with an integrated debugging agent and a remote MCP server for querying traces.

• MCP servers
• AI evals

An MCP server that lets AI agents such as Claude, GPT and Copilot autonomously run more than 150 cybersecurity tools for automated penetration testing, vulnerability discovery and bug-bounty work.

• MCP servers
• Security

An MCP server that bridges the IDA Pro disassembler with AI assistants, giving them tools to read and edit binaries for reverse engineering, though the author now recommends the official Hex-Rays MCP server instead.

• MCP servers
• Security

An MCP plugin that adds semantic code search over an entire codebase to Claude Code and other AI coding agents, storing embeddings in a vector database instead of loading whole directories into context.

• MCP servers
• RAG

The official TypeScript SDK for building Model Context Protocol servers and clients, running on Node.js, Bun and Deno, with optional middleware adapters for common web frameworks.

• MCP servers

A Model Context Protocol server that bridges AI assistants such as Claude, Codex and Cursor with the Unity Editor, giving them tools to manage assets, control scenes, edit scripts, run tests and automate game-development workflows.

• MCP servers

An open-source library and MCP server that turns PDFs, Word documents, HTML, images and other unstructured files into clean, structured data ready for language models, vector databases and other downstream processing.

• MCP servers
• RAG

A Model Context Protocol server that gives an AI coding agent access to Figma design data, so it can implement a UI from a Figma file more accurately than from a pasted screenshot.

• MCP servers
• Design tools

An MCP server that gives an AI assistant direct access to Xiaohongshu (RedNote), letting it log in, publish image or video posts, search content, read post details and comments, and post comments on the user's behalf.

• MCP servers

An open-source Model Context Protocol server that connects AI agents, IDEs and applications directly to databases such as PostgreSQL, MySQL, BigQuery, MongoDB and Spanner, with prebuilt tools and a framework for building custom, secured database tools.

• MCP servers
• Databases

An open-source curriculum that teaches the fundamentals of the Model Context Protocol through hands-on, cross-language code examples in C#, Java, TypeScript, JavaScript, Rust and Python.

• MCP servers
• Tutorials

An MCP server that gives AI assistants such as Claude structured knowledge of n8n's workflow nodes, properties and operations, so they can build and configure n8n workflows.

• MCP servers
• Workflow automation

An MCP server that reduces how much raw tool output enters an AI coding agent's context window, tracks session state in SQLite for recovery after compaction, and encourages agents to run scripts instead of reading large amounts of data directly.

• MCP servers
• Agent memory

An open-source, local-first 3D architectural editor built with React Three Fiber and WebGPU, usable from the browser or a CLI, with MCP tools for connecting AI agents.
