An open Markdown convention for telling coding agents how your project works
There are no required fields or special syntax. Use any headings you like and the agent parses the text you provide.
One AGENTS.md works across dozens of coding agents such as Codex, Cursor, Jules, Aider, Gemini CLI, Zed and Copilot.
Drop extra AGENTS.md files into subpackages; agents read the nearest file in the directory tree, so local instructions take precedence.
Keeps human-facing READMEs concise while giving agents the build, test and convention details they actually need.
Discover and share Model Context Protocol servers for AI agents and coding tools
Find servers by name, category, tag, runtime or integration, with featured, trending and newest sections that track community activity.
Review hosted MCP endpoints, authentication requirements and per-client setup instructions before you connect anything.
Discover MCP-compatible clients, official command-line tools, agent loops and reusable Claude/Codex skills in dedicated sections.
Maintainers can publish new servers and claim existing listings so entries stay accurate and attributable.
