RECOMMENDED RULE

The rule that runs util_csv_filter_rows safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Delx Protocol — Agent Recovery & Continuity, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For util_csv_filter_rows, this is the rule to start with:

util_csv_filter_rows Rate-limited

util_csv_filter_rows stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about util_csv_filter_rows

What does the util_csv_filter_rows tool do? +

CSV Filter Rows keeps CSV rows whose column equals one of caller values from bounded caller-supplied values without an external provider. Call CSV Filter Rows before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Filter Rows as versioned deterministic JSON. Limitation: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. It is categorised as a Write tool in the Delx Protocol — Agent Recovery & Continuity MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does util_csv_filter_rows accept? +

util_csv_filter_rows accepts 3 parameters: text, column, allowed. Required: text, column, allowed. The full parameter table on this page comes from the server's own tool schema.
