Known MCP Server Vulnerabilities
The following table outlines critical security vulnerabilities commonly found in MCP server implementations:| Category | Example Vulnerability | Impact |
|---|---|---|
| Command Injection | Unchecked shell command usage | Remote code execution, system compromise |
| Prompt Injection | Malicious text in tool metadata | AI output manipulation, sensitive data leaks |
| Token Theft | Tokens stored insecurely | Attacker gains access to all connected services |
| Malicious Servers | No vetting for third-party servers/tools | Data exfiltration, user impersonation |
| Excessive Privilege | Overly broad access rights | Expanded attack surface, lateral movement |
| Weak Auth/Logging | No or insufficient authentication/logging | Stealthy attacks and undetected breaches |
How AgentPass Solves These Issues
Command Injection Protection
AgentPass prevents command injection attacks through multiple layers of input validation and secure request processing:- All tool parameters undergo comprehensive validation using Zod schema validation
- Input data is strictly typed and validated against predefined schemas
- Malicious payloads are rejected before reaching execution layers
Prompt Injection Mitigation
AgentPass implements multiple strategies to prevent prompt injection attacks:- Content filtering to detect and block malicious prompt patterns
- Structured data validation prevents injection through metadata fields
Secure Token Management
AgentPass provides enterprise-grade token security with multiple authentication strategies: Multi-Strategy Authentication- Flexible authentication system supporting OAuth, JWT, and custom headers
- Strategy pattern implementation allows secure switching between auth methods
- Provider-specific security controls and validation
- JWKS URL validation with timeout and structural integrity checks
- Token signature verification using cryptographically secure methods
- Automatic key rotation support for enhanced security
- Secure token storage with encryption at rest
- Automatic token refresh with proper expiration handling
- Revocation support for compromised or expired tokens
- User-server access validation ensures proper authorization
- Fine-grained permissions at server and tool levels
- Multi-tenant isolation prevents cross-tenant access
Server and Tool Vetting
AgentPass provides comprehensive controls for managing server and tool security: Multi-Tenant Isolation- Strict enforcement of server-tenant relationships
- Cross-tenant access prevention at the infrastructure level
- Isolated execution environments for each tenant
- Controlled tool registration process with validation
- Administrative oversight for tool enablement
- Security scanning for tool configurations
- Per-request server access validation
- Dynamic permission checking based on current context
- Audit trails for all access decisions
- Enabled/disabled states for servers and tools
- Granular control over tool availability
- Emergency disable capabilities for security incidents
Principle of Least Privilege
AgentPass enforces strict access controls to minimize attack surface: Server-Scoped Access- Users can only access servers within their authorized tenant
- No cross-tenant data exposure or tool access
- Strict boundary enforcement at all system levels
- Granular control over individual tool access
- Tool-specific permission requirements
- Runtime permission validation for each execution
Comprehensive Logging and Monitoring
AgentPass provides detailed security monitoring and audit capabilities: Request/Response Logging- Complete API call logging with sanitized sensitive data
- Request tracing for security incident investigation
- Performance monitoring to detect anomalous behavior
All logs are stored securely with encryption and access controls, ensuring that security monitoring doesn’t create additional vulnerabilities.
