fetches list of masters from Tally Prime collection e.g. group, ledger, vouchertype, unit, godown, stockgroup, stockitem, costcategory, costcentre, attendancetype, company, currency, gstin, gstclassification returns output in JSON string array in the property list
AI agents call list-master 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.
The tool retrieves master data (groups, ledgers, units, etc.) from Tally Prime without creating, modifying, deleting, or executing arbitrary operations. This is a straightforward read-only query operation. Blast radius is minimal—misuse would only expose existing data, not cause irreversible changes or financial harm.
From the tool's definition Tool description states it 'fetches list of masters' and 'returns output in JSON string array' — purely a retrieval operation with no modification, deletion, or execution of code/queries.
Documented attack patterns abuse exactly the kind of access list-master 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 list-master:
{
"version": "1",
"default": "deny",
"tools": {
"list-master": {}
}
}list-master is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

It is categorised as a Read tool in the Tally Prime MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tally Prime MCP Server MCP server in PolicyLayer and add a rule for list-master: 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 Tally Prime MCP Server. Nothing to install.
list-master 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-master 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-master. 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-master 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.
