🛡️ The 7-Moat MCPGate Enforcement Boundary
Every tool invocation is cryptographically evaluated through all 7 moats before execution.
Moat #1
Evidence-Backed Trust State
Trust is dynamically computed from verified execution history, never LLM confidence. Actions by untrusted agents are blocked fail-closed.
Moat #2
Security Context Continuity
Authority tokens attenuate monotonically across subagent delegations, preventing privilege escalation and delegation laundering.
Moat #3
Causal Authority Graph
Real-time graph checks detect orphan authority, cross-tenant leaks, and identity substitution before granting tool tokens.
Moat #4
Execution Provenance & Attestation
Binds agent intent to tool parameters, outputs, and side-effects in an immutable RFC 6962 Merkle inclusion tree with Ed25519 signatures.
Moat #5
Predictive Trust & Blast Radius
Simulates worst-case impact before dispatch. High blast radius actions automatically demand two-phase cryptographic quorum.
Moat #6
Adversarial Immunity Engine
Continuous fail-closed defense blocks 120 red-team attack vectors including prompt injection, tool hijacking, and salami attacks.
Moat #7
Autonomous Swarm Control Loop
Hardware-backed kill switch and trajectory quarantine halt compromised swarm agents in <50 milliseconds.
