returns fields metadata for the selected tally collection containing field name, optional description and data type which can be string, number, date or boolean
AI agents call metadata-fields 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 and exposes schema metadata about Tally data structures. It does not modify, delete, execute operations, or process financial transactions. Even in the context of a financial ERP system, querying metadata is a read-only operation with minimal blast radius.
From the tool's definition Tool returns metadata (field names, descriptions, data types) for a Tally collection. The verb 'returns' and the nature of the data—schema/structural information—indicate purely informational retrieval with no side effects.
Attacks that exploit this kind of access
returns fields metadata for the selected tally collection containing field name, optional description and data type which can be string, number, date or boolean. 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 metadata-fields: 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.
metadata-fields 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 metadata-fields 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 metadata-fields. 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.
metadata-fields is provided by the Tally Prime MCP Server MCP server (qalalabs/tally-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
