MCP Endpoint Discovery Checker
Check if your site is ready for AI agent integration via Model Context Protocol
Frequently Asked Questions
What is MCP?
The Model Context Protocol (MCP) is a standard that enables AI agents to discover and interact with website APIs. It defines endpoints at /.well-known/mcp.json.
Who created the MCP standard?
MCP was introduced by Anthropic in late 2024 and is evolving as an open standard for AI agent-to-website communication.
Do I need MCP for my website?
Currently, MCP adoption is very early. It's mainly relevant if you offer APIs or services that AI agents might want to use programmatically.
What does this checker look for?
We check for .well-known/mcp.json and .well-known/openapi.json files, which are the standard discovery endpoints for AI agent protocols.
Is OpenAPI the same as MCP?
No, but they're related. OpenAPI defines your API structure. MCP adds AI-specific metadata like capabilities, authentication for agents, and context descriptions.
How do I add MCP support?
Create a /.well-known/mcp.json file that describes your site's capabilities, API endpoints, and how AI agents should interact with your service.
Does Google support MCP?
As of early 2026, MCP support is primarily from Anthropic Claude and select AI agent frameworks. Google has its own agent protocols but interoperability is growing.
Can MCP replace my API documentation?
No. MCP supplements your API docs by providing machine-readable discovery for AI agents. Human-readable documentation remains essential.
Is there a security risk with MCP?
Like any public API endpoint, MCP should use proper authentication and rate limiting. Never expose sensitive operations without authorization in your MCP manifest.
Will MCP become standard?
The standard is evolving rapidly. Anthropic, Cloudflare, and others support it. We frame it as a draft standard and update our checker as the specification evolves.
