Frequently Asked Questions
What is an MCP server?
An MCP server is a lightweight program that exposes tools, resources, or prompts to AI agents via the Model Context Protocol — an open standard created by Anthropic. Think of it as a plugin that lets your AI read files, query databases, or call APIs through a single, standardized interface.
How many MCP servers are there in 2026?
As of March 2026, the PulseMCP registry lists over 5,500 MCP servers, with roughly 300 new servers added each month. The ecosystem has grown over 230% in the last six months alone.
Are MCP servers safe to use?
MCP servers can execute code on your machine, so you should only install servers from trusted sources. Pin versions, review permissions, and follow the [MCP security best practices](/blog/how-to-build-mcp-server/) outlined in the official spec. For team environments, [cowork.ink](https://cowork.ink) enforces least-privilege access by default.
What is the difference between MCP and A2A?
MCP connects an AI agent to tools and data sources (agent-to-tool), while A2A (Agent-to-Agent) connects agents to each other for delegation and collaboration. They are complementary protocols — see our [MCP vs. A2A comparison](/blog/mcp-vs-a2a/) for details.
Do I need to code to use MCP servers?
No. Most MCP servers install with a single npx or docker command and work out of the box with Claude Desktop, VS Code, Cursor, and other MCP-compatible clients. Configuration is typically a JSON snippet.
