AI agents invoke schema_overview to trigger processes or run actions in Valets Schema. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

schema_overview can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so schema_overview only ever does what you allow.

What does the schema_overview tool do? +

Get a high-level overview of the entire Valets data model. Start here to understand what models and enums exist before drilling into specifics.. It is categorised as a Execute tool in the Valets Schema MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on schema_overview? +

Register the Valets Schema MCP server in PolicyLayer and add a rule for schema_overview: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Valets Schema. Nothing to install.

What risk level is schema_overview? +

schema_overview is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit schema_overview? +

Yes. Add a rate_limit block to the schema_overview rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block schema_overview completely? +

Set action: deny in the PolicyLayer policy for schema_overview. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides schema_overview? +

schema_overview is provided by the Valets Schema MCP server (@ingenx-io/valets-schema-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Valets Schema tool call.
