Model Context Protocol
MCP Servers
MCP servers are how AI agents connect to tools, data, and capabilities. The public registry grew to 9,400+ servers in 2026, with 78% of enterprise AI teams running at least one in production. Browse the best, including AI coding skills via the skills-hub MCP server.
Short answer
MCP servers expose tools and data to AI clients (Claude Code, Cursor, Codex, Windsurf) through a standard JSON-RPC interface. The skills-hub MCP server is the simplest way to add AI coding skills to any MCP-compatible tool, run `npx @skills-hub-ai/mcp` or point your client at the remote endpoint at https://api.skills-hub.ai/mcp.

Frequently asked questions about MCP servers
What are MCP servers?
MCP servers are Model Context Protocol servers, long-running processes that expose tools, resources, and prompts to AI clients (Claude Code, Cursor, Codex CLI, Windsurf, Cline, etc.) through a standard JSON-RPC interface. Use them to wire AI into databases, APIs, file systems, browser automation, vector memory, and SaaS tools.
How many MCP servers exist in 2026?
The public MCP registry grew from 1,200 in early 2025 to 9,400+ servers in 2026, with 78% of enterprise AI teams running at least one MCP server in production. Big growth areas: edge MCP (Cloudflare), vector-memory MCP (Qdrant), marketing automation MCP (HubSpot, Salesforce, Linear), and Amazon Bedrock AgentCore.
What's the best MCP server for AI coding?
Skills-hub.ai's MCP server (@skills-hub-ai/mcp) exposes AI coding skills as MCP prompts. Run claude mcp add skills-hub -- npx @skills-hub-ai/mcp (Claude Code) or point any MCP client at https://api.skills-hub.ai/mcp (remote).
How do I install an MCP server?
Most MCP servers are distributed via npm or Smithery. For Claude Code: claude mcp add <name> -- npx <package>. For Cursor: edit .cursor/mcp.json. For Windsurf, Cline, GitHub Copilot Chat: their respective MCP configs. The skills-hub MCP server is also available as a remote HTTP endpoint requiring no local install.
Are MCP servers the same as agent skills?
No. MCP servers expose tools and data (read DB, hit API, control browser). Agent Skills (SKILL.md) are reusable natural-language instructions. They compose, the skills-hub MCP server exposes installed skills as MCP prompts, bringing both standards together.
Which AI tools support MCP in 2026?
Claude Code, Claude Desktop, Cursor, Windsurf, Codex CLI, Cline, Continue.dev, GitHub Copilot Chat (via MCP integration), Google Antigravity 2.0 (launched May 19 2026), and AWS Kiro (via Amazon Bedrock AgentCore). 30+ clients total.
