Public repositories
11 live- deliverability-guard A sending circuit breaker for outbound email. Watches reputation, bounce, complaint and warmup signals per mailbox and throttles or pauses before a domain burns. Refuses to trip on statistically meaningless data.
- segment-mcp A read-first MCP server for Twilio Segment. Answers which destinations get which events, which sources are dead, and which are governed by nothing. Read-only by default; data deletion is not exposed at all.
- agent-audit A portable record binding what an agent proposed, what a human decided, what executed, and what it cost. An OpenTelemetry semantic convention plus a thin emitter. The record, not the enforcer.
- n8n-operator Governed MCP control plane for safely operating approved n8n workflows from Claude, OpenAI, Codex, and compatible clients.
- notion-mcp Public repository.
- pipeline-waterfall dbt package for B2B bookings and pipeline waterfall analytics — created, advanced, pushed, slipped, pulled in, won, lost, expanded, contracted, reopened. Reconciles or fails.
