List all ledger accounts
AI agents call list-accounts to retrieve information from Ledger 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 and queries ledger account information without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal risk if misused by an AI agent, as it only exposes existing account metadata.
From the tool's definition Tool name 'list-accounts' and description 'List all ledger accounts' indicate a retrieval operation with no modification or side effects. The verb 'list' is explicitly listed in the Read category guidelines.
Attacks that exploit this kind of access
List all ledger accounts. It is categorised as a Read tool in the Ledger MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ledger MCP Server 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 Ledger MCP Server. 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 Ledger MCP Server MCP server (mprokopov/ledger-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
