About kafka-schema-reg-mcp
aywengo/kafka-schema-reg-mcp
A comprehensive Message Control Protocol (MCP) server for Kafka Schema Registry.
Exposes 50+ MCP tools for schema discovery, registration, and validation across multiple Kafka Schema Registry instances via JSON-RPC stdio transport. Built on FastMCP 2.8.0+ with MCP 2.025-06-18 compliance, it enables Claude Desktop and other clients to manage schemas across isolated contexts (production/staging), migrate schemas between registries, and export in multiple formats—with SLIM_MODE reducing tool overhead for optimized LLM performance.
About streamnative-mcp-server
streamnative/streamnative-mcp-server
Developer-friendly MCP server bridging Kafka and Pulsar protocols—built with ❤️ by StreamNative for an agentic, streaming-first future.
Implements both stdio and SSE transport modes with multi-session support for per-user Pulsar authentication, enabling isolated connections through HTTP bearer tokens and LRU-cached sessions. Exposes comprehensive admin and client operations across Kafka (topics, Schema Registry, Connect) and Pulsar (tenants, functions, sources/sinks) alongside StreamNative Cloud cluster management via service account authentication. Built in Go with protocol version negotiation and supports Docker/Kubernetes deployment through Homebrew, binaries, or Helm charts.
