Kafka Schema Registry MCP Server is a true MCP implementation designed for Claude Desktop and other MCP clients to manage Kafka Schema Registry operations through JSON-RPC over stdio. Built on the FastMCP 2.8.0+ framework, it adheres to the MCP 2025-06-18 specification, delivering full MCP compatibility with a rich set of tools (57+). The server provides advanced schema-context support, multi-registry management (up to eight registries), and comprehensive export capabilities in JSON and Avro IDL formats for backups, documentation, and audits. It includes production safety features such as VIEWONLY mode and per-registry access controls, along with OAuth 2.1 authentication for enterprise-grade security and scope-based permissions. It supports real-time progress tracking and cancellation of long-running tasks, HATEOAS-enabled resource navigation, and a mix of read, write, admin, and interactive tools. An optional SLIM_MODE reduces the exposed tool set to a lean subset, significantly improving LLM performance while preserving essential functionality and remote deployment support.
