A service that turns any website into clean Markdown or structured data for models. It can search, scrape, crawl a whole site and even click through a page.
A small Microsoft utility that converts PDF, Word, PowerPoint, Excel and other files into Markdown that is easy to hand to a language model.
An open coding agent for the terminal with a desktop app. It is not tied to one provider: plug in whichever models you have.
A toolkit for spec-driven development: principles and a spec first, then a plan and tasks, and only then code. Works with several coding agents.
OpenAI's lightweight coding agent that runs in the terminal and works on your project's code. Written in Rust.

The largest community-curated list of MCP servers, sorted by category from databases to browsers. The place to look for an existing server before writing your own.
Reference MCP servers from the protocol team: memory, git, filesystem and more. A solid pattern for how a server is built and a ready set to start with.
Feeds fresh, version-specific library docs into the prompt so the model stops inventing outdated APIs. Works as an MCP server or through a CLI with a skill.
Hands Chrome DevTools to an agent: network, console, performance, screenshots. The agent does not just click, it sees why a page is slow or broken.
A Playwright-based MCP server that lets an agent drive a browser through page structure rather than screenshots. Good for testing sites and automating web actions.
GitHub's official MCP server: an agent reads repositories, issues and pull requests and works with them. Comes as a hosted version from GitHub and a local one in Docker.
A toolkit for coding agents that works with code semantically: finds symbols and references and edits through language servers instead of rereading whole files. Saves context on large projects.
A Python framework that hides the protocol plumbing: a decorated function becomes an MCP tool. The shortest path from idea to a working server.
The official Python SDK for MCP, used to write both servers and clients. A server with a single tool fits in a couple dozen lines.
A free MCP course from Microsoft: from basics and security to first servers, with examples in C#, Java, JavaScript, Rust, Python and TypeScript.
Gives a coding agent the structure of a Figma design: layers, spacing, colors. The code ends up closer to the design than it would from a screenshot.
The official TypeScript SDK for MCP, split into server and client packages with optional adapters for Node, Express and Fastify.
A visual debugger for MCP servers: connect your server, browse its tools and call them by hand. Comes as a web UI, a CLI and a TUI.
A full-stack MCP framework: server, built-in inspector and deploy in one project. Can build UI views for tools that open inside ChatGPT and Claude.
A collection of open-source MCP servers for AWS: infrastructure, docs, data, AI services. Lets an agent work with Amazon's cloud in a controlled way.
The source of truth for MCP: the specification, protocol schema and official docs. This is where the way models connect to tools and data gets defined.
Firecrawl's official MCP server: scraping, search and site crawling for an agent. Offers a hosted keyless free tier or a local run through npx.
The official Go SDK for MCP, maintained together with Google. A server is built from `mcp.Server`, tools and a transport.
Notion's official MCP server: an agent searches, reads and edits pages and databases. Access follows the integration's permissions, so you can grant read-only.
Supabase's official MCP server: an agent manages projects, tables and SQL right from chat. Runs as a hosted server with login through your Supabase account.
