TL;DR: Three Grade A papers published in the last 10 days define a new security layer Ruflo lacks — authorization propagation across agent delegation chains — distinct from the content-screening gap (ADR-131) filed five nights ago.
| Finding | Source | Confidence |
|---|---|---|
| 40.55% of 7,973 live MCP servers expose tools with zero authentication; 96.6% of OAuth-enabled servers contain ≥1 flaw | arXiv:2605.22333 | A |
| Runtime authority control (AIRGuard) reduces agent attack success 36.3% → 5.5% via least-privilege action-layer enforcement | arXiv:2605.28914 | A |
| Dual-graph provenance defense (execution graph vs authorization intent) reduces indirect prompt injection 40% → 1% | arXiv:2605.26497 | A |
| Authorization propagation across multi-agent delegation chains is not reducible to prompt injection; requires 7 structural requirements not covered by RBAC/ABAC | arXiv:2605.05440 | A |
| Single agents false-continue on infeasible tool tasks 73.9% of the time (intelligence scan) | arXiv:2605.28532 | A |
| Event-triggered swarm consensus reduces network overhead while maintaining ≥99% task completion under agent failures (swarm scan) | arXiv:2604.06813 | A |
| Control | Status | Gap |
|---|---|---|
| Content-boundary injection screening | ADR-131 (Proposed) | Covers WHAT agents receive — not WHO they act as |
| MCP tool input validation | SafeExecutor + InputValidator | No auth verification on MCP server identity |
| Per-action privilege enforcement | Not implemented | No action → scope → allow/deny path |
| Delegation chain tracking in SendMessage | Not implemented | Messages carry no authorization scope |
| Execution provenance graph | Not implemented | No WHAT did vs WHAT was authorized audit trail |
| Feasibility pre-check before tool dispatch | Not implemented | 73.9% false-continue risk on single-agent paths |
| Framework | MCP Auth Checking | Per-Action Privilege | Authorization Propagation | Provenance Graph |
|---|---|---|---|---|
| Ruflo v3.6 | Not implemented | Not implemented | Not implemented | Not implemented |
| OpenAI Agents SDK | Tool availability pre-check (March 2026) | Input + output + invocation guardrails | OAuth 2.0 token forwarding | OTEL spans built-in |
| LangGraph v0.4 | Via LangSmith observability | Conditional edges + HITL checkpoints | Partial (checkpoint-scoped) | LangSmith full graph |
| CrewAI Enterprise | SOC 2 / HIPAA compliance | Role-scoped tool permissions | Partial (role inheritance) | Observability hooks |
| AutoGen 1.0 GA | Security patches; no MCP native | GroupChat-level only | Not published | Azure Monitor integration |

Implement AgentAuthorizationPropagator in v3/@claude-flow/security/src/authorization/propagator.ts — attach scope field to SendMessage envelope, validate each MCP tool call against the current delegation scope. ADR-144 (filed tonight) tracks this as an architectural decision.
Add MCP server authentication validator in v3/@claude-flow/cli/src/mcp/auth-validator.ts — before any tool response enters agent reasoning, verify the server presented valid credentials. Even a simple allowlist check eliminates the 40.55% unauthenticated-server risk for Ruflo-managed MCP registrations.
Add feasibility pre-check to the route hook — before Tier-3 dispatch, verify all required MCP tools are registered and callable. Eliminates the 73.9% false-continue rate at near-zero cost (simple registry lookup). Implementation-level — no ADR needed.
