I created MCP AQL, which is an extension to the MCP spec, specifically to reduce the bloat for MCP tools.
It only has five CRUDE endpoint: Create, Read, Update, Delete, and Execute using a GraphQL-like structure for tool calling of the operations within the endpoints. It's very efficient, and robust. there's all kinds of exemplar tools and components to make adapters for any MCP server. You don't even need to rewrite your own MCP server. Just create an adapter for it.
