SMCP

Secure Model Context Protocol - A security-first MCP gateway addressing 24 security risks and 12 critical market gaps

24 Security Risks 12 Market Gaps 4C Framework

SMCP Implementation Roadmap

Overview

This roadmap synthesizes requirements from three sources: 1. SMCP Paper (2602.01129v1) - Secure Model Context Protocol specification 2. 4C Framework Paper (2602.01942v1) - Human-society-inspired security framework 3. Market Research - 12 critical gaps in existing MCP gateway solutions

The goal is to build a comprehensive, security-first MCP gateway that addresses all 24 identified security risks while filling market gaps that no current solution addresses.

Phase 1: Foundation (Core Infrastructure)

Objective: Establish the fundamental security substrate - the "digital body" of SMCP.

1.1 Trusted Component Registry

Addresses: 4C Core Layer, SMCP Identity Management

1.2 Security Context Implementation

Addresses: SMCP Security Context, Session Security

interface SecurityContext {
  sessionId: string;
  callChainId: string;
  delegatorChain: Delegator[];
  callerAgentId: string;
  peerId: string;
  authnAssertionId: string;
  riskLevel: 'low' | 'medium' | 'high' | 'critical';
  dataSensitivity: 'public' | 'internal' | 'sensitive' | 'highly_sensitive';
  policyRef: string;
  timestamp: string;
  nonce: string;
}

1.3 Authentication & Session Manager

Addresses: SMCP R1-R4 (Unauthenticated Access, Weak Auth, Session Flaws)

1.4 Transport Security

Addresses: SMCP R8-R9 (Insecure Communication, Transport Downgrades)

Phase 2: Policy & Access Control

Objective: Implement the brain of authorization decisions.

2.1 Policy Engine (PDP/PEP)

Addresses: SMCP Policy Enforcement, 4C Compliance Layer

2.2 Delegation Chain Validation

Addresses: SMCP R5-R7 (Privilege Escalation, Confused Deputy)

2.3 Tool-Level Access Control

Addresses: SMCP R10-R13 (Tool Poisoning, Excessive Permissions, Rug Pull)

2.4 Data Sensitivity Controls

Addresses: SMCP R19-R21 (Sensitive Data Exposure)

Phase 3: Audit & Observability

Objective: Complete visibility into all system actions for compliance and forensics.

3.1 Comprehensive Audit Logging

Addresses: SMCP Audit Requirements, 4C Compliance Layer

3.2 Audit Log Schema

interface AuditEntry {
  entryId: string;
  timestamp: string;
  eventType: AuditEventType;
  actor: { type: string; id: string; delegatorChain: string[]; };
  action: { type: string; target: string; parameters: Record<string, any>; };
  decision: { result: string; policyRef: string; obligations?: string[]; };
  context: { sessionId: string; callChainId: string; riskLevel: string; };
  signature: string;
  previousEntryHash: string;
}

3.3 Real-Time Monitoring

Phase 4: Threat Detection & Prevention

Objective: Active defense against known attack patterns.

4.1 Prompt Injection Detection

4.2 Tool Poisoning Prevention

4.3 Command Injection Prevention

4.4 Formal Tool Behavior Verification

Market Gap: Critical - No current solution addresses this

Phase 5: Advanced Security Features

Objective: Address sophisticated attack vectors and market differentiation.

5.1 Semantic Intent Analysis

Market Gap: No gateway currently implements this

5.2 Ephemeral Credentials & Secret Management

5.3 Human-in-the-Loop Workflows

5.4 Belief & Goal Integrity (4C Cognition)

Phase 6: Enterprise Features

6.1 Multi-Tenancy

6.2 Federation & Interoperability

6.3 Offline / Air-Gapped / Edge Deployment

6.4 Cost Attribution & Chargeback

Phase 7: Compliance & Governance

7.1 Regulatory Compliance

7.2 Governance Interfaces
