Check and normalize a rules object against the provider
AI agents call dsers_rules_validate to retrieve information from DSers MCP Product without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs validation and normalization of a rules object, which is a read-like operation that inspects and processes data in-memory without side effects. No creation, deletion, execution, or financial transactions occur. Despite the server's broader context involving imports and store pushes, this specific tool's scope is limited to validation logic.
From the tool's definition Tool description states 'Check and normalize a rules object against the provider' — validates/checks a rules object without modifying data or executing external operations.
