MCP Production Gate

One security gate for production MCP systems

MCP Production Gate is a unified security and production-readiness suite for modern MCP deployments.

It combines multiple security engines behind six high-level tools to audit MCP servers, inspect tool calls before execution, sanitize sensitive outputs, analyze protocol traces, detect security regressions, and generate remediation plans.

What it checks

• MCP protocol and deployment security
• JSON Schema safety and bounded validation
• Tool metadata poisoning and suspicious changes
• Dangerous or destructive tool-call arguments
• Human-approval requirements
• Sensitive filesystem paths and path traversal
• Shell and SQL destructive patterns
• SSRF and unsafe outbound destinations
• OAuth issuer, PKCE, audience and token boundaries
• Cache isolation and cross-user reuse
• State-handle integrity
• Tasks lifecycle integrity
• MRTR integrity
• MCP Apps security
• Secrets and PII in tool outputs
• Policy-as-code rules
• Tool/catalog drift and security regressions

Six tools

audit_mcp_server Run a complete security and production-readiness audit with a 0–100 score, A–F grade, normalized findings and evidence fingerprints.

guard_tool_call Inspect an MCP tool invocation before execution and return ALLOW, WARN or BLOCK based on schema validation, security risks and configurable policies.

sanitize_tool_output Detect and redact credentials, API keys, tokens, private keys and optional personal information before results enter AI context.

audit_protocol_trace Analyze OAuth, cache, state, Tasks, MRTR and MCP App protocol activity for integrity problems.

compare_security_posture Compare approved and current security reports to detect new vulnerabilities, regressions and unexpected tool changes.

generate_remediation_plan Turn findings into a prioritized GO, CONDITIONAL or NO-GO remediation plan with retest criteria.

Built for production

Production Gate uses deterministic security analysis and does not require an external LLM to make its security decisions.

Its philosophy is simple:

Fail closed when security evidence is insufficient.

Designed for MCP developers, AI-agent platforms, automation agencies, DevSecOps teams and organizations deploying MCP systems in production.

MCP Production Gate is a security engineering aid and does not represent a compliance certification or guarantee that a system is vulnerability-free.
