Best MCP Servers for Security Engineering in 2026

AI-Assisted Security with MCP

Security engineers need to audit code, manage access control, monitor infrastructure, and respond to incidents - fast. MCP servers give your AI assistant direct access to security tools.

Here are 6 verified MCP servers from the Spark catalog for security work.

1. Keycloak MCP Server (by Ido Widya Yudhatama)

Full Keycloak administration through natural language - user management, client configuration, realm settings, and RBAC operations.

Security use case: "Audit all service accounts in the production realm. List any with admin roles that haven't been used in 30 days."

Pros: Simple setup · Focused on common operations
Cons: Less comprehensive than the full version

3. Thales CDSP CAKM MCP Server

Database encryption operations using CipherTrust Application Key Management (CAKM). Manage TDE (Transparent Data Encryption) for SQL Server and Oracle.

Security use case: "Rotate the TDE master key for the production Oracle database and verify all tablespaces are re-encrypted."

Pros: Enterprise-grade encryption · SQL Server + Oracle support · Key lifecycle management
Cons: Requires CipherTrust infrastructure

4. System Health MCP Server

Real-time server monitoring via SSH - including security-relevant metrics like open ports, failed login attempts, and process lists.

Security use case: "Check all production servers for unusual processes, open ports not in our allowlist, and recent failed SSH attempts."

Pros: Security metrics included · No agent installation · SSH-based
Cons: Linux-only

5. kill-process-mcp Server

Cross-platform process management. View running processes and terminate resource-intensive or suspicious ones.

Security use case: "Find any processes listening on unexpected ports and show me their command lines."

Pros: Cross-platform · Natural language process queries · Immediate response
Cons: Requires appropriate system permissions

6. Extended Memory MCP Server

Track security findings, vulnerability patterns, and compliance requirements across review sessions.

Security use case: "Remember that we found a CORS misconfiguration last week. Check if it was fixed in this deployment."

View on Spark →

Pros: Persistent findings tracking · Per-project isolation · Pattern memory
Cons: Manual initial setup
