WHAT IT DOES

Parameter	Type	Required	Description
`limit`	integer	—	Maximum number of ranked filers to return.
`end_date`	string	Yes	Inclusive end date in YYYY-MM-DD format.
`filer_type`	string	—	Whether to rank owners, law firms, or individual correspondents.
`start_date`	string	Yes	Inclusive start date in YYYY-MM-DD format.
`nice_classes`	array	—	Optional Nice classes to filter by. Use integers like 42 or 9.

Parameters from the server's own tool schema.

RISK

Why get_top_filers is rated Low

Even though get_top_filers only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

get_top_filers Allowed

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