Config Validator
A resource page for configuration hygiene across prompts, retrieval, MCP servers, environment secrets, and AI deployment defaults.
Misconfigurations that turn safe features into exploitable paths.
Config changes escaping review because they look operational, not security-critical.
Untrusted MCP or agent config becoming direct command or access paths.
Built For
Platform teams standardizing AI configuration practices.
Security reviewers auditing deployment defaults and config drift.
Teams dealing with fast-moving MCP and agent ecosystem configs.
Use Cases
Map unsafe defaults in prompts, tool configs, MCP registration, and secret exposure.
Create review checklists for changing AI and agent configurations.
Reduce silent config drift in high-change environments.

Frequently Asked Questions
Is this tied to MCP only?
No. MCP is one important example, but the resource is broader and covers AI and agent configuration hygiene overall.
Why make configuration a dedicated resource?
Because many AI incidents are enabled by defaults, wiring, and policy gaps rather than a single “bug” in the model itself.
