AI agents call list_plans to retrieve information from HelloBooks AI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
plan | string | — | Restrict the response to a single plan tier (`cpa` = free Partner Program). |
country | string | — | ISO country code. Filters prices to one country. Omit to return all 8 markets. |
Parameters from the server's own tool schema.
This tool retrieves and displays publicly available pricing information, plan features, and signup URLs. It performs read-only queries filtered by plan type or country, with no ability to create, modify, delete, execute code, or commit financial transactions. The low blast radius reflects minimal risk even if misused by an agent — it only exposes pricing data already public.
From the tool's definition Tool name is "list_plans" and description states it "List[s] HelloBooks pricing plans" and "Returns AI credit allowance, feature bullets..., and the public signup URL." The verb is "list" and "returns" — retrieval operations with no side effects.
Attacks that exploit this kind of access
List HelloBooks pricing plans with monthly + annual prices in 8 regional currencies (USD, INR, CAD, GBP, AUD, AED, SGD, NZD). Covers four core tiers — Free / Pro / Business / Partner Program (the cpa plan id) — plus two per-entity stackable add-ons (Warehouse, Manufacturing). Returns AI credit allowance, feature bullets (AI auto-categorization, unlimited users, multi-entity, 3-way matching, API access, etc.), and the public signup URL. Filter by plan (one of free / pro / business / cpa) or country (ISO code). Pricing follows Doc 19 v3 (Web-Fire #514, 2026-06-12): Business re-introduced as a 4th tier sized ~4× Pro to match Partner Points; the retired "$59.99/mo + $4.99/client" CPA SKU is gone and the cpa plan id now resolves to the free Partner Program (call partner_program_info for the status ladder + points math). HelloCPA Practice Management is a separate product on practice.hellobooks.ai — call practice_management_info, NOT this 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_plans accepts 2 parameters: plan, country. 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_plans: 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_plans 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_plans 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_plans. 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_plans 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.
