Make AI safe to connect to real systems
Security gateway for MCP servers — secures databases, APIs, filesystems, cloud platforms, and DevOps tools with deterministic policy enforcement.
WORKS WITH
All AI agents that support the Model Context Protocol
Secure Every System Your AI Touches
MCPShield protects all real systems through secure adapters — not limited to databases and APIs
New systems are added via adapters — extend MCPShield to any resource your AI needs
Built for Security-First Teams
Default Deny
Every operation starts blocked. You explicitly allow what you trust.
Deterministic Policies
Same inputs always produce the same result. No ambiguity, no surprises.
Comprehensive Auditing
Every allowed and blocked request is logged. Full visibility into AI behavior.
Zero Trust Architecture
Never trust, always verify. Validate every request against your policy.
Universal System Support
Databases, APIs, cloud platforms, filesystems, DevOps tools, and internal services — all secured with unified policies.
Claude Code Integration
Drop-in replacement for stdio MCP servers. Works seamlessly with Claude.

How It Works
Three simple steps to secure AI access
Define Your Policy
Write a simple YAML or JSON policy file defining what operations are allowed across all your systems.
# policy.yaml
default: deny
allow:
- pattern: "SELECT .* FROM analytics.*"
- pattern: "GET /api/public/.*"
- path: "./reports/.*"
deny:
- keywords: ["DELETE", "DROP"]
- path: ".*/.ssh/.*"Run MCPShield Gateway
Point your AI tool at MCPShield. Works with any adapter — databases, APIs, filesystems, cloud, and more.

--audit audit.logMonitor & Audit
Review allowed and blocked operations across all systems. Full visibility into AI behavior.
# audit.log
[ALLOWED] postgres.query: SELECT * FROM analytics
[BLOCKED] postgres.query: DROP TABLE users
[ALLOWED] rest.request: GET /api/public/status
[BLOCKED] fs.read: ~/.ssh/id_rsaSecurity Principles
Deterministic
Same input always produces same output. No LLM interpretation in the policy layer.
Auditable
Every request is logged with timestamp, operation, and decision.
Default Deny
Nothing is allowed unless explicitly permitted in your policy.
