Reviewer Notes

Valkey is self-hosted software with solid technical documentation but lacks agent-specific discovery mechanisms like MCP servers or OpenAPI specs. Agents can authenticate programmatically via ACL or AUTH, and can deploy locally without signup, but there's no cloud-hosted free tier or managed service offering. The wire protocol is well-documented and client libraries exist, but no structured API specification limits discoverability for LLM-based agents unfamiliar with Redis protocol internals.
