# See server.py for full implementation

Wire it up — full stack

This MCP is part of the MEOK chain that turns one agent action into a fully signed compliance event. See meok.ai/mcp-stack for the 6-MCP chain:

1. bft-progress-council-mcp — anti-loop guardrail
2. agent-token-budget-mcp — hard spend cap
3. agent-content-watermark-mcp — EU AI Act Article 50(2) watermark
4. meok-eu-aigc-icon-mcp — EU Code-of-Practice icon (Nov 2026 cliff)
5. agent-audit-logger-mcp — hash-chained audit trail
6. a2a-governance-bridge-mcp — fold all signatures into one signed event

Output: ONE auditor-defensible evidence event mapped to EU AI Act Articles 12 + 50, DORA Article 17, ISO 42001 clause 9 — plus a public verify URL.
