Hell yeah! I had this idea since MCP came out, but I FINALLY got it to work: OpenAPI to MCP is a fact:

Convert ANY server described with openapi into an MCP endpoint!

mcp.openapisearch.com/anyhostname.tld/mcp

There are a few requirements to it, but: If the server serves REST described with OpenAPI and if it either has NO auth OR implements OAUTH the MCP way, it will automatically work!
