List all ledger accounts (id, name, type, archived). No date parameter. Use this to resolve account names to IDs before recording transactions.
AI agents call list_accounts to retrieve information from Finance App without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of account information. While it provides data useful for downstream operations (resolving account IDs for transactions), the tool itself does not create, modify, delete, or execute actions. The blast radius of misuse is minimal—an agent could see all account names and IDs but cannot alter financial state.
From the tool's definition Tool description explicitly states 'List all ledger accounts' and 'resolve account names to IDs', indicating retrieval of account metadata. No modifications, deletions, or state changes are possible.
Attacks that exploit this kind of access
List all ledger accounts (id, name, type, archived). No date parameter. Use this to resolve account names to IDs before recording transactions. It is categorised as a Read tool in the Finance App MCP Server, which means it retrieves data without modifying state.
Register the Finance App MCP server in PolicyLayer and add a rule for list_accounts: 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 Finance App. Nothing to install.
list_accounts 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_accounts 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_accounts. 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_accounts is provided by the Finance App MCP server (youssefaltai/finance-app). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
