This is the JSON Schema for server.json, the manifest the Model Context Protocol registry uses to describe a published MCP server: its name, version, packages, remotes and transport. It is published by the MCP project at https://static.modelcontextprotocol.io/schemas/2025-09-29/server.schema.json and is reproduced here verbatim so MCP server manifests harvested into the catalog can be validated.
