## Wire it up — full stack

Pair this with the MEOK chain that turns one agent action into ONE signed compliance event:

1. bft-progress-council-mcp — anti-loop guardrail
2. agent-token-budget-mcp — hard spend cap
3. agent-prompt-injection-firewall-mcp — OWASP LLM01 scan
4. agent-audit-logger-mcp — hash-chained evidence
5. a2a-governance-bridge-mcp — fold N attestations → 1 signed event
6. agent-incident-relay-mcp — broadcast incidents to 5 regimes simultaneously

See meok.ai/mcp-stack for the full architecture and meok.ai/mcp-stack/demo for the live in-browser demo.
