0mcp
Turn your OpenAPI specification into a hosted MCP server
A managed platform that transforms OpenAPI specifications into hosted MCP servers without requiring API modifications or protocol infrastructure.
Overview
The 0mcp homepage
0mcp is a developer platform for building, hosting, versioning, and monitoring Model Context Protocol servers from APIs. Import your OpenAPI spec, choose which endpoints to expose to AI clients, and deploy a hosted MCP server without building the protocol layer yourself. Your existing backend remains unchanged, and 0mcp handles hosting, authentication forwarding, versioning, and production observability. The platform stores only operational metadata like status, latency, and errors—not API request or response payloads.
