Dokumentum blokkok (számlatömbök) listázása. Számla létrehozásához szükséges a block_id.
AI agents call list_document_blocks to retrieve information from Billingo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries information about document blocks (invoice number ranges/sequences) without creating side effects. It is a simple data lookup operation that an invoice system requires to present options to users. The severity is low because misuse would only expose metadata about available invoice blocks, not compromise financial data or enable destructive actions.
From the tool's definition The tool is described as 'listázása' (listing) document blocks, which is a retrieval operation that returns a list of available blocks needed for invoice creation. No data modification, deletion, or financial transaction occurs.
Documented attack patterns abuse exactly the kind of access list_document_blocks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Billingo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_document_blocks:
{
"version": "1",
"default": "deny",
"tools": {
"list_document_blocks": {}
}
}list_document_blocks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Billingo MCP Server MCP server in PolicyLayer and add a rule for list_document_blocks: 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 Billingo MCP Server. Nothing to install.
list_document_blocks 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_document_blocks 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_document_blocks. 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_document_blocks is provided by the Billingo MCP Server MCP server (szotasz/billingo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Billingo MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
