Foundational concepts behind MCP servers. Start here if you are new to the Model Context Protocol.
How Safe Are MCP Servers? We Scanned Over 10,000
We security-scanned more than 10,000 MCP servers. About 1 in 4 scores above low risk, 1 in 8 has a critical finding, and nearly 1 in 3 has a serious supply-chain issue. Here is the full data.
What Makes an MCP Server Secure (and the 5 Ways They Go Wrong)
A secure MCP server gets five things right. We scanned 10,000+ to find where they actually fail. Supply chain is the big one; the server's own code almost never is.
MCP servers vs AI agents: when to use which
MCP servers give AI tool access. Agents give AI decision-making. When to use each, when to combine them, and how they fit together in production.
MCP vs function calling: what is the difference?
MCP servers and function calling both let AI use external tools. Here is how they differ, when to use each, and why many teams use both together.
Are MCP servers safe? A security guide
MCP servers can access your files, credentials, and APIs. Here is how to evaluate whether a server is safe to install, what the real risks are, and how security scanning works.
MCP server vs API: what is the difference?
MCP servers and APIs both connect software to services, but they serve different purposes. Here is what sets them apart and when to use each.
What is an MCP server?
MCP servers let AI assistants like Claude connect to real tools: your files, calendar, databases, and APIs. Here is what they are and why they matter.
