MCP Servers, Clients & Tools
A growing directory of tools in the Model Context Protocol ecosystem — the open standard for connecting AI assistants to your data, APIs, and workflows.
What is MCP?
Model Context Protocol (MCP) is an open standard created by Anthropic that lets AI assistants like Claude connect to external data sources and tools through a unified interface. Instead of every AI app reinventing integrations with Google Drive, Slack, GitHub, or your database — they can all speak MCP.
Think of it as the USB-C of AI integrations: one protocol, hundreds of plugs.
Pieces of the MCP ecosystem
- MCP Servers — programs that expose data or tools (a Postgres database, Notion workspace, GitHub repo) via the MCP protocol
- MCP Clients — apps that consume MCP (Claude Desktop, Cursor, various IDE plugins)
- MCP Hosting — cloud platforms that run MCP servers for you
- MCP Gateway / Proxy — routing infrastructure between clients and many servers
- MCP Inspector / DevTools — debug and observability tools for MCP traffic
We're listing them all on a single page for now — the ecosystem is too young to split into sub-pages with confidence. As coverage grows, we'll break it out.
