The building blocks powering the next generation of AI applications
Model Context Protocol (MCP) servers are standardized interfaces that let AI models interact with external tools and data sources -- bridging large language models with file systems, databases, APIs, and web services. Originally developed by Anthropic, MCP has become the dominant protocol for extending AI agent capabilities.
AI skills are modular capabilities that extend AI agents and language models. Unlike MCP servers which follow a specific protocol, skills encompass custom tool definitions, function calling schemas, and plugin architectures across multiple platforms -- giving developers a unified view rather than searching dozens of disconnected registries.
Every indexed tool undergoes automated security analysis covering code quality, dependency vulnerabilities, maintenance frequency, license compliance, and known CVEs. AI agents that execute code or install packages on behalf of users introduce supply-chain risk -- security grades help developers quickly identify trustworthy tools for production use.
A single MCP server might be listed on the official registry, published on npm, hosted on GitHub, and curated in multiple community directories. Skillful.sh aggregates and cross-references tools from 55+ sources into one unified directory with live GitHub stats, package registry downloads, and cross-listing data so you can gauge true ecosystem adoption.
From a few hundred MCP servers at the start of 2025, the ecosystem now includes over 415,878 tools spanning MCP servers, AI skills, and autonomous agents. Skillful.sh tracks this growth in real time with ecosystem statistics, trending tools, and growth charts that show how the landscape is evolving week by week.
