MCP Security Best Practices: Authentication, Authorization & Supply Chain Protection

Understanding MCP Security Model

MCP’s security model is built on clear trust boundaries between hosts (AI applications) and servers (context providers). Understanding these boundaries and implementing appropriate security controls at each layer enables organizations to safely leverage MCP’s capabilities while protecting sensitive resources.

Trust Boundaries in MCP

// MCP establishes clear trust boundaries
interface SecurityBoundaries {
  // Host (AI application) boundary
  host: {
    authenticatesServers: boolean;      // Host validates server identity
    authorizesRequests: boolean;        // Host controls what requests to make
    sandboxesServers: boolean;          // Host isolates server execution
  };

  // Server (context provider) boundary
  server: {
    authenticatesHosts: boolean;        // Server validates host identity
    authorizesAccess: boolean;          // Server controls resource access
    validatesInputs: boolean;           // Server sanitizes all inputs
  };

  // Transport boundary
  transport: {
    encrypted: boolean;                 // Communication encrypted in transit
    mutualTLS: boolean;                 // Both parties authenticate
  };
}

Authentication Strategies

Server Authentication

Hosts must verify server identity before establishing connections to prevent man-in-the-middle attacks and unauthorized servers.

interface ServerAuthConfig {
  // Certificate-based authentication
  tls?: {
    ca: string;                         // Certificate authority
    cert?: string;                      // Client certificate
    key?: string;                       // Client key
    rejectUnauthorized: boolean;        // Enforce certificate validation
  };

  // Token-based authentication
  apiKey?: {
    header: string;                     // Authorization header name
    token: string;                      // API token value
    prefix?: string;                    // Token prefix (e.g., "Bearer")
  };

  // OAuth 2.0 authentication
  oauth?: {
    tokenEndpoint: string;
    clientId: string;
    clientSecret: string;
    scope: string[];
  };
}

// Example: Secure server connection with TLS
const secureClient = new MCPClient({
  serverConfig: {
    command: 'mcp-server',
    args: ['--secure'],
    env: {
      SERVER_API_KEY: process.env.MCP_SERVER_API_KEY
    }
  },
  transport: {
    type: 'https',
    url: 'https://mcp-server.example.com',
    tls: {
      ca: fs.readFileSync('/path/to/ca-cert.pem'),
      rejectUnauthorized: true
    },
    headers: {
      'Authorization': `Bearer ${process.env.MCP_API_TOKEN}`
    }
  }
});

Host Authentication

Servers should authenticate hosts to ensure only authorized applications can access resources.

// Server-side host authentication
class SecureMCPServer implements MCPServer {
  private authorizedHosts: Map<string, HostCredentials>;

  async authenticateHost(request: ConnectionRequest): Promise<boolean> {
    // Extract credentials from request
    const apiKey = request.headers['authorization']?.replace('Bearer ', '');

    if (!apiKey) {
      throw new Error('Missing authentication credentials');
    }

    // Validate against known hosts
    const hostCreds = this.authorizedHosts.get(apiKey);
    if (!hostCreds) {
      throw new Error('Invalid credentials');
    }

    // Verify credentials haven't expired
    if (hostCreds.expiresAt < Date.now()) {
      throw new Error('Credentials expired');
    }

    // Check IP allowlist if configured
    if (hostCreds.allowedIPs && !hostCreds.allowedIPs.includes(request.ip)) {
      throw new Error('IP not authorized');
    }

    return true;
  }

  async initialize(params: InitializeParams): Promise<ServerCapabilities> {
    await this.authenticateHost(params.connectionRequest);
    return this.capabilities;
  }
}

Centralized Authentication Management

Centralized configuration management enables consistent authentication policies across all MCP deployments, reducing security risks from misconfiguration.

// Centralized authentication configuration
interface CentralAuthConfig {
  defaultAuthMethod: 'apiKey' | 'oauth' | 'mtls';

  // API key management
  apiKeys: {
    rotationPolicy: 'manual' | 'automatic';
    rotationInterval?: number;          // Days
    keyLength: number;
    allowedOrigins?: string[];
  };

  // OAuth configuration
  oauth: {
    provider: 'okta' | 'auth0' | 'custom';
    tokenEndpoint: string;
    scopes: string[];
    tokenLifetime: number;              // Seconds
  };

  // Mutual TLS configuration
  mtls: {
    caPath: string;
    clientCertRequired: boolean;
    allowedCertificates?: string[];
  };
}

Organizations using Tetrate Agent Router Service (TARS) benefit from centralized authentication management that simplifies credential distribution and policy enforcement across all MCP servers and hosts.

Authorization and Access Control

Resource-Level Authorization

Implement fine-grained access controls to ensure hosts only access authorized resources.

interface ResourceACL {
  resource: string;                     // Resource URI
  allowedHosts: string[];               // Host identifiers
  permissions: ResourcePermissions;      // Read, write, execute
  conditions?: AccessConditions;         // Contextual conditions
}

interface ResourcePermissions {
  read: boolean;
  write: boolean;
  execute: boolean;
}

interface AccessConditions {
  timeRestrictions?: {
    allowedHours: number[];             // 0-23
    timezone: string;
  };
  ipRestrictions?: {
    allowedCIDRs: string[];
  };
  rateLimit?: {
    requestsPerMinute: number;
  };
}

class AuthorizationService {
  async authorizeResourceAccess(
    hostId: string,
    resourceUri: string,
    permission: keyof ResourcePermissions,
    context: RequestContext
  ): Promise<boolean> {
    // Load ACL for resource
    const acl = await this.loadResourceACL(resourceUri);

    // Check if host is allowed
    if (!acl.allowedHosts.includes(hostId)) {
      this.auditLog.warn('Unauthorized resource access attempt', {
        hostId,
        resourceUri,
        permission
      });
      return false;
    }

    // Check permission level
    if (!acl.permissions[permission]) {
      return false;
    }

    // Evaluate conditional access
    if (acl.conditions) {
      if (!await this.evaluateConditions(acl.conditions, context)) {
        return false;
      }
    }

    return true;
  }

  private async evaluateConditions(
    conditions: AccessConditions,
    context: RequestContext
  ): Promise<boolean> {
    // Time-based restrictions
    if (conditions.timeRestrictions) {
      const hour = new Date().getHours();
      if (!conditions.timeRestrictions.allowedHours.includes(hour)) {
        return false;
      }
    }

    // IP-based restrictions
    if (conditions.ipRestrictions) {
      const clientIP = context.clientIP;
      const allowed = conditions.ipRestrictions.allowedCIDRs.some(cidr =>
        this.ipInCIDR(clientIP, cidr)
      );
      if (!allowed) {
        return false;
      }
    }

    // Rate limiting
    if (conditions.rateLimit) {
      const requestCount = await this.getRequestCount(
        context.hostId,
        60 * 1000 // Last minute
      );
      if (requestCount >= conditions.rateLimit.requestsPerMinute) {
        return false;
      }
    }

    return true;
  }
}

Tool-Level Authorization

Control which hosts can invoke specific tools to prevent unauthorized actions.

class ToolAuthorizationService {
  private toolACLs: Map<string, ToolACL>;

  async authorizeToolCall(
    hostId: string,
    toolName: string,
    args: Record<string, unknown>
  ): Promise<boolean> {
    const acl = this.toolACLs.get(toolName);
    if (!acl) {
      // Deny by default if no ACL defined
      return false;
    }

    // Check host authorization
    if (!acl.allowedHosts.includes(hostId)) {
      return false;
    }

    // Validate argument constraints
    if (acl.argumentConstraints) {
      for (const [param, constraint] of Object.entries(acl.argumentConstraints)) {
        const value = args[param];

        // Type validation
        if (constraint.type && typeof value !== constraint.type) {
          return false;
        }

        // Range validation for numbers
        if (constraint.min !== undefined && value < constraint.min) {
          return false;
        }
        if (constraint.max !== undefined && value > constraint.max) {
          return false;
        }

        // Pattern validation for strings
        if (constraint.pattern && !new RegExp(constraint.pattern).test(String(value))) {
          return false;
        }

        // Enum validation
        if (constraint.allowedValues && !constraint.allowedValues.includes(value)) {
          return false;
        }
      }
    }

    return true;
  }
}

interface ToolACL {
  toolName: string;
  allowedHosts: string[];
  argumentConstraints?: Record<string, ArgumentConstraint>;
}

interface ArgumentConstraint {
  type?: 'string' | 'number' | 'boolean' | 'object' | 'array';
  min?: number;
  max?: number;
  pattern?: string;
  allowedValues?: unknown[];
}

TARS provides profile-based access control that enables teams to define granular permissions for resources and tools, ensuring principle of least privilege across MCP deployments.

Supply Chain Security

MCP’s extensible server ecosystem introduces supply chain risks similar to those seen in npm, PyPI, and other package ecosystems. The 2020 SolarWinds attack and numerous npm package compromises demonstrate the critical importance of supply chain security.

Server Provenance Verification

Verify the authenticity and integrity of MCP servers before deployment.

interface ServerProvenance {
  name: string;
  version: string;
  publisher: string;
  publisherVerified: boolean;          // Publisher identity verified
  signatures: {
    algorithm: 'ed25519' | 'rsa';
    publicKey: string;
    signature: string;
  }[];
  checksums: {
    algorithm: 'sha256' | 'sha512';
    value: string;
  }[];
  buildAttestation?: {
    builder: string;                    // CI/CD system
    sourceRepo: string;
    commitHash: string;
    buildTime: string;
  };
}

class ServerProvenanceVerifier {
  async verifyServer(serverPath: string, provenance: ServerProvenance): Promise<boolean> {
    // Verify checksums
    const actualChecksum = await this.computeChecksum(serverPath, provenance.checksums.algorithm);
    if (actualChecksum !== provenance.checksums.value) {
      throw new Error('Checksum verification failed');
    }

    // Verify signatures
    for (const sig of provenance.signatures) {
      const valid = await this.verifySignature(
        serverPath,
        sig.publicKey,
        sig.signature,
        sig.algorithm
      );
      if (!valid) {
        throw new Error('Signature verification failed');
      }
    }

    // Verify publisher
    if (provenance.publisherVerified) {
      const trusted = await this.verifyPublisher(provenance.publisher);
      if (!trusted) {
        throw new Error('Publisher not trusted');
      }
    }

    // Verify build provenance (SLSA compliance)
    if (provenance.buildAttestation) {
      const buildValid = await this.verifyBuildAttestation(
        provenance.buildAttestation
      );
      if (!buildValid) {
        throw new Error('Build attestation verification failed');
      }
    }

    return true;
  }
}

Trusted Server Catalog

Maintain a curated catalog of verified MCP servers to prevent malicious or vulnerable servers from being deployed.

interface TrustedServerCatalog {
  servers: Map<string, TrustedServer>;

  // Catalog management
  addServer(server: TrustedServer): Promise<void>;
  removeServer(serverName: string): Promise<void>;
  updateServer(server: TrustedServer): Promise<void>;

  // Verification
  isServerTrusted(name: string, version: string): Promise<boolean>;
  getServerInfo(name: string): Promise<TrustedServer | null>;

  // Security scanning
  scanServer(serverPath: string): Promise<ScanResults>;
}

interface TrustedServer {
  name: string;
  versions: {
    version: string;
    releaseDate: string;
    securityScan: {
      lastScanned: string;
      vulnerabilities: Vulnerability[];
      riskScore: number;              // 0-100
    };
    provenance: ServerProvenance;
    allowedEnvironments: ('dev' | 'staging' | 'production')[];
  }[];
  maintainer: {
    name: string;
    email: string;
    verified: boolean;
  };
  repository: string;
  license: string;
  securityPolicy?: string;            // URL to SECURITY.md
}

interface Vulnerability {
  id: string;                         // CVE-ID or similar
  severity: 'low' | 'medium' | 'high' | 'critical';
  description: string;
  affectedVersions: string[];
  patchedVersion?: string;
  mitigation?: string;
}

TARS includes a trusted MCP catalog that provides pre-vetted, security-scanned servers with verified provenance, reducing supply chain risks for enterprise deployments.

Dependency Scanning

Continuously scan MCP server dependencies for known vulnerabilities, similar to tools like Snyk, Dependabot, or FINOS’s security scanning initiatives.

class DependencyScannerService {
  async scanServerDependencies(serverPath: string): Promise<ScanResults> {
    // Parse dependency manifest (package.json, requirements.txt, etc.)
    const dependencies = await this.parseDependencies(serverPath);

    const vulnerabilities: Vulnerability[] = [];

    for (const dep of dependencies) {
      // Check against vulnerability databases
      const cveResults = await this.checkNVD(dep.name, dep.version);
      const ossIndexResults = await this.checkOSSIndex(dep.name, dep.version);
      const ghAdvisories = await this.checkGitHubAdvisories(dep.name, dep.version);

      vulnerabilities.push(
        ...cveResults,
        ...ossIndexResults,
        ...ghAdvisories
      );
    }

    // Calculate risk score
    const riskScore = this.calculateRiskScore(vulnerabilities);

    // Check for known malicious packages
    const maliciousChecks = await this.checkMaliciousPackages(dependencies);

    return {
      scannedAt: new Date().toISOString(),
      dependencies,
      vulnerabilities,
      riskScore,
      maliciousPackages: maliciousChecks.malicious,
      recommendations: this.generateRecommendations(vulnerabilities)
    };
  }

  private calculateRiskScore(vulnerabilities: Vulnerability[]): number {
    const weights = {
      critical: 40,
      high: 20,
      medium: 5,
      low: 1
    };

    const score = vulnerabilities.reduce((sum, vuln) => {
      return sum + weights[vuln.severity];
    }, 0);

    return Math.min(100, score);
  }
}

Input Validation and Sanitization

Prevent injection attacks by validating and sanitizing all inputs at host and server boundaries.

class InputValidator {
  // Validate resource URIs to prevent path traversal
  validateResourceURI(uri: string): boolean {
    // Prevent path traversal attempts
    if (uri.includes('..') || uri.includes('~')) {
      throw new SecurityError('Invalid resource URI: path traversal detected');
    }

    // Validate URI scheme
    const allowedSchemes = ['file', 'http', 'https', 'db', 's3'];
    const scheme = uri.split(':')[0];
    if (!allowedSchemes.includes(scheme)) {
      throw new SecurityError(`Invalid resource URI scheme: ${scheme}`);
    }

    // Validate against allowlist if configured
    if (this.resourceAllowlist && !this.resourceAllowlist.test(uri)) {
      throw new SecurityError('Resource URI not in allowlist');
    }

    return true;
  }

  // Validate tool arguments to prevent injection
  validateToolArguments(
    toolName: string,
    args: Record<string, unknown>
  ): Record<string, unknown> {
    const schema = this.toolSchemas.get(toolName);
    if (!schema) {
      throw new SecurityError(`No schema defined for tool: ${toolName}`);
    }

    // Type validation
    for (const [key, value] of Object.entries(args)) {
      const paramSchema = schema.properties[key];
      if (!paramSchema) {
        throw new SecurityError(`Unknown parameter: ${key}`);
      }

      // Check type
      if (typeof value !== paramSchema.type) {
        throw new SecurityError(
          `Invalid type for ${key}: expected ${paramSchema.type}, got ${typeof value}`
        );
      }

      // Sanitize strings
      if (typeof value === 'string') {
        args[key] = this.sanitizeString(value, paramSchema.sanitization);
      }

      // Validate ranges for numbers
      if (typeof value === 'number' && paramSchema.range) {
        if (value < paramSchema.range.min || value > paramSchema.range.max) {
          throw new SecurityError(`Value for ${key} out of allowed range`);
        }
      }
    }

    return args;
  }

  private sanitizeString(input: string, rules?: SanitizationRules): string {
    let sanitized = input;

    if (rules?.maxLength) {
      sanitized = sanitized.slice(0, rules.maxLength);
    }

    if (rules?.allowedCharacters) {
      const regex = new RegExp(`[^${rules.allowedCharacters}]`, 'g');
      sanitized = sanitized.replace(regex, '');
    }

    if (rules?.escapeHTML) {
      sanitized = this.escapeHTML(sanitized);
    }

    if (rules?.disallowedPatterns) {
      for (const pattern of rules.disallowedPatterns) {
        if (new RegExp(pattern).test(sanitized)) {
          throw new SecurityError('Input contains disallowed pattern');
        }
      }
    }

    return sanitized;
  }
}

Data Privacy and Compliance

Sensitive Data Handling

Implement controls to prevent exposure of sensitive data through MCP.

interface DataClassification {
  level: 'public' | 'internal' | 'confidential' | 'restricted';
  categories: DataCategory[];
  retentionPolicy: {
    duration: number;                 // Days
    deletionMethod: 'soft' | 'hard';
  };
  encryptionRequired: boolean;
  accessLoggingRequired: boolean;
}

type DataCategory =
  | 'PII'                             // Personally Identifiable Information
  | 'PHI'                             // Protected Health Information
  | 'PCI'                             // Payment Card Industry data
  | 'ITAR'                            // International Traffic in Arms Regulations
  | 'IP'                              // Intellectual Property
  | 'FERPA';                          // Education records

class DataPrivacyService {
  async classifyResource(uri: string): Promise<DataClassification> {
    const content = await this.readResource(uri);

    // Scan for sensitive data patterns
    const categories: DataCategory[] = [];

    if (this.containsPII(content)) categories.push('PII');
    if (this.containsPHI(content)) categories.push('PHI');
    if (this.containsPCI(content)) categories.push('PCI');

    // Determine classification level
    const level = this.determineClassificationLevel(categories);

    return {
      level,
      categories,
      retentionPolicy: this.getRetentionPolicy(level),
      encryptionRequired: level !== 'public',
      accessLoggingRequired: categories.length > 0
    };
  }

  private containsPII(content: string): boolean {
    // SSN pattern
    if (/\b\d{3}-\d{2}-\d{4}\b/.test(content)) return true;

    // Email addresses
    if (/\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b/.test(content)) return true;

    // Phone numbers
    if (/\b\d{3}[-.]?\d{3}[-.]?\d{4}\b/.test(content)) return true;

    return false;
  }

  async redactSensitiveData(
    content: string,
    classification: DataClassification
  ): Promise<string> {
    let redacted = content;

    if (classification.categories.includes('PII')) {
      // Redact SSNs
      redacted = redacted.replace(/\b\d{3}-\d{2}-\d{4}\b/g, '***-**-****');

      // Redact email addresses
      redacted = redacted.replace(
        /\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b/g,
        '[EMAIL REDACTED]'
      );
    }

    if (classification.categories.includes('PCI')) {
      // Redact credit card numbers
      redacted = redacted.replace(
        /\b\d{4}[-\s]?\d{4}[-\s]?\d{4}[-\s]?\d{4}\b/g,
        '****-****-****-****'
      );
    }

    return redacted;
  }
}

Audit Logging

Maintain comprehensive audit logs for compliance and security monitoring.

interface AuditLogEntry {
  timestamp: string;
  eventType: AuditEventType;
  hostId: string;
  userId?: string;
  serverId: string;
  resourceUri?: string;
  toolName?: string;
  action: string;
  result: 'success' | 'failure';
  errorMessage?: string;
  dataClassification?: DataClassification;
  ipAddress: string;
  userAgent?: string;
}

type AuditEventType =
  | 'authentication'
  | 'authorization'
  | 'resource_access'
  | 'tool_invocation'
  | 'configuration_change'
  | 'security_event';

class AuditLogger {
  async logEvent(entry: AuditLogEntry): Promise<void> {
    // Add metadata
    const enrichedEntry = {
      ...entry,
      id: this.generateEventId(),
      correlationId: this.getCorrelationId(),
      sessionId: this.getSessionId()
    };

    // Write to secure audit log
    await this.writeToAuditLog(enrichedEntry);

    // Alert on security events
    if (this.isSecurityEvent(entry)) {
      await this.sendSecurityAlert(enrichedEntry);
    }

    // Check for compliance violations
    if (await this.violatesCompliancePolicy(entry)) {
      await this.handleComplianceViolation(enrichedEntry);
    }
  }

  private isSecurityEvent(entry: AuditLogEntry): boolean {
    return entry.eventType === 'security_event' ||
           entry.result === 'failure' ||
           (entry.dataClassification?.level === 'restricted');
  }
}

TARS provides unified observability and audit logging across all MCP servers, enabling centralized security monitoring, compliance reporting, and threat detection.

Network Security

Transport Encryption

Always encrypt MCP communication in production environments.

// TLS configuration for production
const productionTransportConfig: TransportConfig = {
  type: 'https',
  url: 'https://mcp-server.example.com',
  tls: {
    minVersion: 'TLSv1.3',
    ciphers: [
      'TLS_AES_256_GCM_SHA384',
      'TLS_AES_128_GCM_SHA256',
      'TLS_CHACHA20_POLY1305_SHA256'
    ].join(':'),
    ca: fs.readFileSync('/path/to/ca-bundle.pem'),
    cert: fs.readFileSync('/path/to/client-cert.pem'),
    key: fs.readFileSync('/path/to/client-key.pem'),
    rejectUnauthorized: true,
    checkServerIdentity: (hostname, cert) => {
      // Custom certificate validation
      return tls.checkServerIdentity(hostname, cert);
    }
  }
};

Rate Limiting

Implement rate limiting to prevent abuse and DoS attacks.

Security Testing

Implement comprehensive testing and quality assurance for MCP security controls.

// Security test suite
describe('MCP Security', () => {
  describe('Authentication', () => {
    it('should reject connections without valid credentials', async () => {
      const client = new MCPClient({ auth: { apiKey: 'invalid' } });
      await expect(client.connect()).rejects.toThrow('Authentication failed');
    });

    it('should reject expired tokens', async () => {
      const expiredToken = generateExpiredToken();
      const client = new MCPClient({ auth: { token: expiredToken } });
      await expect(client.connect()).rejects.toThrow('Token expired');
    });
  });

  describe('Authorization', () => {
    it('should prevent unauthorized resource access', async () => {
      const client = await createLimitedClient();
      await expect(
        client.readResource('file:///etc/passwd')
      ).rejects.toThrow('Access denied');
    });

    it('should prevent unauthorized tool invocation', async () => {
      const client = await createLimitedClient();
      await expect(
        client.callTool('delete_all_data', {})
      ).rejects.toThrow('Access denied');
    });
  });

  describe('Input Validation', () => {
    it('should prevent path traversal attacks', async () => {
      const client = await createClient();
      await expect(
        client.readResource('file://../../etc/passwd')
      ).rejects.toThrow('Invalid resource URI');
    });

    it('should prevent SQL injection in tool arguments', async () => {
      const client = await createClient();
      await expect(
        client.callTool('query_database', {
          query: "'; DROP TABLE users; --"
        })
      ).rejects.toThrow('Invalid input');
    });
  });
});

Best Practices

1. Implement Defense in Depth

Layer multiple security controls rather than relying on a single mechanism.

2. Follow Principle of Least Privilege

Grant minimum necessary permissions for each host and server.

3. Maintain Secure Defaults

Configure systems securely by default, requiring explicit opt-in for reduced security.

4. Monitor and Alert

Implement comprehensive performance monitoring with security event alerting.

5. Regular Security Audits

Conduct periodic security reviews of MCP configurations, ACLs, and audit logs.

6. Keep Dependencies Updated

Regularly update MCP servers and dependencies to patch vulnerabilities.

7. Implement Incident Response

Maintain documented procedures for responding to security incidents.

Conclusion

Securing MCP implementations requires a comprehensive approach encompassing authentication, authorization, supply chain security, data privacy, and continuous monitoring. By implementing robust security controls at each layer of the MCP architecture and following implementation best practices, organizations can safely leverage MCP’s capabilities while protecting sensitive resources and maintaining compliance.

Understanding how MCP security compares to alternatives helps inform security architecture decisions. Organizations should also consider cost optimization techniques that maintain security posture while maximizing efficiency.
