WHAT IT DOES

What crow_list_posts does on Crow

AI agents call crow_list_posts to retrieve information from Crow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The tool performs a query/list operation to retrieve blog posts based on filters. This is a read-only operation with no side effects, reversible modifications, code execution, data destruction, or financial impact. The blast radius of misuse is minimal—at worst, an AI agent could retrieve unintended posts, but no data would be modified, deleted, or compromised.

From the tool's definition Tool name 'crow_list_posts' and description 'List blog posts with filtering' indicate data retrieval operations with no modification or deletion of data.

RECOMMENDED RULE

The rule that runs crow_list_posts safely

crow_list_posts Allowed

crow_list_posts is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Crow, apply this rule, and every crow_list_posts call is checked against it from then on.
