MCP Server

10 tools exposed via FastMCP (stdio + streamable-HTTP transport)
Bearer auth middleware wrapping FastMCP's ASGI app for remote access
DNS-rebinding protection via ROTATOR_MCP_ALLOWED_HOSTS
Deployed as rotator-mcp.service (systemd) on VPS, Tailscale-fronted
Multi-host wiring: Windows, VPS shell, iPhone-via-SSH -- all share the same MCP endpoint

Phase A -- rotator call --device N: mic capture via sounddevice, Deepgram nova-3 streaming STT (ru+en), TranscriptBuffer with rolling state + markdown persistence to ~/.rotator/calls/<session>.md
Phase B -- call_consult MCP tool: dispatches every final utterance to Claude Code subprocess with a 5-layer composable system prompt. Textual TUI gains bubble panel (yellow border) for structured responses. ConversationState with rolling window of 30 turns.
Shared brain dispatch (call/consult.py) eliminates code duplication between local orchestrator and MCP tool paths

M1 -- @with_telemetry decorator wraps all 10 MCP tools. Records tool name, latency_ms, args_hash, timestamp to SQLite. Fail-soft: never lets observability break the system being observed.
M2 -- rotator_self_report MCP tool: Claude self-reports per-tool verdicts (helpful/neutral/waste) at session end. waste signal is the primary feedback for prompt improvement.
rotator usefulness today CLI: per-tool call counts, avg/p95 latency, self-report verdicts

MNEMO client with TTL cache, async httpx, 9 evidence URI schemes
Hierarchical chronicle builder (daily/weekly/monthly) -- reads events from MNEMO, synthesizes via LLM, posts structured chronicle back
Session notes: append-only markdown per conversation
