Frequently Asked Questions
What is MCP?
MCP (Model Context Protocol) is an open standard for connecting AI agents to tools and data sources. It provides a universal interface for tool registration, invocation, and resource access, so agents can discover and use tools without custom integration code for each one.
How is MCP different from a REST API?
REST is stateless and request-response. MCP maintains persistent connections between agents and tools, supports bidirectional communication, and includes built-in tool discovery. An agent can ask an MCP server 'what can you do?' and get a structured capability list. REST APIs require documentation and custom client code.
Who created MCP?
Anthropic created and open-sourced MCP. It's now an open standard with implementations across the AI ecosystem. NimbleBrain has built 21+ MCP servers and created the MCP Trust Framework (MTF) for security assessment.
Do I need MCP to build AI agents?
You don't need it, but you'll end up rebuilding it. Without MCP, every tool connection requires custom code, custom auth handling, and custom error management. MCP standardizes all of this. Teams that skip MCP spend weeks on integration plumbing that MCP handles out of the box.
Is MCP production-ready?
Yes. MCP servers are running in production at enterprises today. NimbleBrain deploys MCP-based agent systems for clients including Scout Motors, AEP Hawaii, and IPinfo. The protocol is stable, and the ecosystem is growing fast, mpak.dev hosts a searchable registry of MCP servers with security scanning.
