Local Private-AI Deployment Guide. A procedure for sizing and securing a local Ubuntu AI deployment: mapping the real privacy/data-flow boundary first (local inference doesn't make retrieval, plugins, telemetry, or backups local), inventorying actual usable VRAM/RAM with a safety reserve before picking a model, installing as a versioned pinned service rather than an ad hoc shell launch, benchmarking on representative tasks (not just tokens/sec), binding interfaces to loopback with…

MCP Server Builder and Auditor. A structured method for building or auditing an MCP server: inventory every tool's data access, side effects, cost, and reversibility; design unique action-object names with strict JSON Schema (required fields, enums, bounds); enforce authorization server-side from authenticated identity rather than tool arguments; require confirmation and idempotency keys for consequential actions; return bounded, sanitized, provenance-carrying output; and test through a real…
