Parameters from the server's own tool schema.
This tool retrieves and queries reference data (tax rates and jurisdictional rules) with no side effects, no data modification, and no execution of external operations. It is purely informational lookup. While the HelloBooks server automates financial operations, this particular tool performs only a read operation on static regulatory reference data, making it low-risk and appropriate for Read category.
From the tool's definition Tool name is 'list_tax_rates' and description states it 'List[s] statutory tax-rate slabs by jurisdiction' with filtering by country, taxType, and scheme. Returns metadata including effective dates and source URLs.

List statutory tax-rate slabs by jurisdiction — IN GST (5/12/18/28 + zero + exempt + composition trader/manufacturer/restaurant + compensation cess), UK VAT (20 / 5 / zero / exempt), AU GST (10 / GST-free), US sales-tax (state-administered summary, no federal rate), CA GST 5% + HST 13% ON / 15% Atlantic, SG GST 9%, NZ GST 15%, AE VAT 5%. Filter by country, taxType (GST/VAT/Sales-Tax/HST/IGST/CGST-SGST/TDS/TCS), or scheme (standard / reduced / zero / exempt / composition / cess / state-summary). Every entry carries an effective-from date and an authoritative source URL (CBIC, gov.uk, ATO, CRA, IRAS, IRD, FTA, Tax Foundation) — agents should confirm the rate against the source before quoting figures to a user. Use this when a user asks "what is the GST rate on X?", "what VAT band does Y fall into?", or "what are the composition slabs in India?". This is the public statutory reference — for an org-specific tax assignment use the authenticated books_classify_event tool. It is categorised as a Read tool in the HelloBooks AI MCP Server MCP Server, which means it retrieves data without modifying state.
list_tax_rates accepts 3 parameters: scheme, country, taxType. The full parameter table on this page comes from the server's own tool schema.
Register the HelloBooks AI MCP Server MCP server in PolicyLayer and add a rule for list_tax_rates: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches HelloBooks AI MCP Server. Nothing to install.
list_tax_rates is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_tax_rates rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_tax_rates. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_tax_rates is provided by the HelloBooks AI MCP Server MCP server (Meru-Fin-Tech/HelloBooks-MCP-Public). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
