A recursive close handler and stale client session IDs show why transport lifecycle needs explicit states and failure-focused tests.
Designing a Read-Only MCP Server for BookStack
Read-only defaults, separate identities, bounded context, session cleanup, and honest health checks matter more than exposing more tools.
Home Assistant with Local Ollama on an RTX 5070 Ti
Measured latency, model sizing, availability, entity exposure, false action claims, memory, and the boundary between language and deterministic code.
Make a Power-Switched WLED Cove Reliable in Home Assistant
