fetches ledger closing balance as on date, negative is debit and positive is credit, display Dr for Debit or Cr for Credit after the amount for better readability, instead of negative amount flip Debit or Credit to make it positive
AI agents call ledger-balance to retrieve information from Tally Prime 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 financial data from Tally Prime without side effects. It queries ledger balances and formats the display—classic read-only behavior. No data creation, modification, deletion, or external command execution is possible. While it accesses financial data (which may be sensitive), the tool itself cannot move money or create financial obligations, making it Read rather than Financial.
From the tool's definition Tool name 'ledger-balance' and description 'fetches ledger closing balance as on date' indicate data retrieval with no modification capability.
Documented attack patterns abuse exactly the kind of access ledger-balance gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tally Prime MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ledger-balance:
{
"version": "1",
"default": "deny",
"tools": {
"ledger-balance": {}
}
}ledger-balance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

ledger-balance is provided by the Tally Prime MCP Server MCP server (dhananjay1405/tally-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Tally Prime MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
