What lookup_ifsc does on Mcp India Stack
AI agents call lookup_ifsc to retrieve information from Mcp India Stack without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why lookup_ifsc is rated Low
This tool retrieves or queries financial institution identifier data (IFSC codes) from a master database. It has no capacity to modify, delete, execute commands, or move money. Even if misused by an AI agent, the worst outcome would be retrieving incorrect or irrelevant banking codes, which is low-impact. The empty description prevents elevation of confidence beyond 0.95, but the context is sufficiently clear.
From the tool's definition Tool name 'lookup_ifsc' indicates a lookup/query operation on IFSC (Indian Financial System Code) master data. Server description explicitly lists 'master data lookups (IFSC, Pincode, HSN/SAC)' as a key function.

The rule that runs lookup_ifsc safely

lookup_ifsc is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp India Stack, apply this rule, and every lookup_ifsc call is checked against it from then on.
