Show HN: MCP Gateway – Turn existing APIs and databases into MCP servers

Based, MCP Gateway – Turn existing APIs and databases into MCP servers works in show hn launch.

Profile

We built MCP Gateway to make existing APIs and databases usable by AI agents through MCP, without writing a custom MCP server for each system. It can analyze OpenAPI specs and SQL sources, generate tool definitions, route agent calls, and log usage. We also built a web chat module so users can interact with connected systems through a simple chat interface.

The company sits in the show hn launch segment, where it competes on its core product or service.

It is recorded at the Show HN launch stage.
