What compare_llc_costs does on FilingDesk Data
AI agents call compare_llc_costs to retrieve information from FilingDesk Data without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | integer | — | How many states to return. Defaults to 10. |
sortBy | string | — | Which cost to sort ascending by. Defaults to firstYear (formation + one recurring period). |
states | array | — | State codes or names to compare. Omit to rank all 50 states + DC. |
Parameters from the server's own tool schema.
Why compare_llc_costs is rated Low
Even though compare_llc_costs 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
The rule that runs compare_llc_costs safely
PolicyLayer is an MCP gateway: it sits between your AI agents and FilingDesk Data, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For compare_llc_costs, this is the rule to start with:
compare_llc_costs is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect FilingDesk Data, apply this rule, and every compare_llc_costs call is checked against it from then on.
