Corelayer0 – Turn any OpenAPI spec into a hosted MCP server
Corelayer0 allows developers to convert any OpenAPI specification into a hosted MCP (Model Context Protocol) server, enabling AI models to directly interact with existing APIs without custom integration code.
Background
Corelayer0 is a service that converts any OpenAPI specification (a standard machine-readable format for describing REST APIs) into a hosted MCP (Model Context Protocol) server. MCP is an open protocol developed by Anthropic that lets AI assistants like Claude directly interact with external tools, databases, and APIs in real time. This means developers can plug existing REST APIs into AI agents without writing custom integration code — the spec is uploaded, and Corelayer0 produces a server the AI can talk to. It lowers the barrier to making AI assistants capable of taking actions (e.g., booking a flight, querying a CRM) rather than just generating text.
