fetches HSN-wise summary of GST transactions for a date range with fields hsn_code, description, uqc (unit quantity code), quantity, taxable_value, cgst_amount, sgst_amount, igst_amount, cess_amount, total_tax, invoice_value. useful for GST return filing (GSTR-1 HSN summary). returns output cache...
AI agents call gst-hsn-summary 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 and summarizes existing GST transaction data for a date range. It performs a read/query operation, caching results in an in-memory DuckDB table for further analysis. No data is created, modified, deleted, or any financial transaction is initiated. The severity is low as it only reads reporting data.
From the tool's definition fetches HSN-wise summary of GST transactions... useful for GST return filing (GSTR-1 HSN summary). returns output cached in DuckDB in-memory table

fetches HSN-wise summary of GST transactions for a date range with fields hsn_code, description, uqc (unit quantity code), quantity, taxable_value, cgst_amount, sgst_amount, igst_amount, cess_amount, total_tax, invoice_value. useful for GST return filing (GSTR-1 HSN summary). returns output cached in DuckDB in-memory table (specified in tableID property). Use query-database tool to run SQL queries against that table for further analysis. 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 gst-hsn-summary: 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.
gst-hsn-summary 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 gst-hsn-summary 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 gst-hsn-summary. 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.
gst-hsn-summary is provided by the Tally Prime MCP Server MCP server (jina-code-systems/tally-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
