# Security

> Understand how AgentPass addresses critical MCP server security vulnerabilities and provides enterprise-grade protection

Model Context Protocol (MCP) servers enable powerful AI agent integrations but introduce significant security risks. Without proper security measures, MCP servers can become attack vectors for command injection, data theft, and system compromise.

## 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

**JWT Provider Validation**

* JWKS URL validation with timeout and structural integrity checks
* Token signature verification using cryptographically secure methods
* Automatic key rotation support for enhanced security

**OAuth Token Lifecycle**

* Secure token storage with encryption at rest
* Automatic token refresh with proper expiration handling
* Revocation support for compromised or expired tokens

**Access Control**

* 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

**Tool Registration Control**

* Controlled tool registration process with validation
* Administrative oversight for tool enablement
* Security scanning for tool configurations

**Access Validation**

* Per-request server access validation
* Dynamic permission checking based on current context
* Audit trails for all access decisions

**Administrative Controls**

* 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

**Tool-Level Permissions**

* 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

> [!NOTE]
>
> All logs are stored securely with encryption and access controls, ensuring that security monitoring doesn't create additional vulnerabilities.

## Enterprise Security Features

AgentPass provides additional enterprise security capabilities:

* **SSO Integration**: Enterprise identity provider integration
* **API Rate Limiting**: Protection against abuse and DoS attacks
* **IP Allowlisting**: Network-level access controls
* **Encryption at Rest**: All data encrypted using industry-standard algorithms
* **Audit Trails**: Comprehensive audit logging for compliance
