Yeah auth is not part of the MCP spec at the moment. This thread has the current state of the world though: https://github.com/modelcontextprotocol/specification/discussions/64 https://github.com/modelcontextprotocol/specification/discus... And there's a concrete PR open at https://github.com/modelcontextprotocol/specification/pull/101 https://github.com/modelcontextprotocol/specification/pull/1... which suggests that there will be an auth capability with both oauth and credential (api keys etc) which seems like it will make it's way into the next release of the spec
