## Why searchISIN is rated Low

searchISIN performs data lookup and retrieval operations only. It queries the FMP ISIN API to return financial identifiers and associated company metadata. No side effects occur; the tool neither modifies data, executes code, deletes records, nor commits financial transactions. This is a standard Read operation with minimal blast radius if misused by an AI agent.

From the tool's own definition: "Tool description states it 'search and retrieve' ISIN data and 'find key details' including company name, stock symbol, and market capitalization. These are read-only query operations with no data modification or execution capabilities."

## Use case

AI agents call searchISIN to retrieve information from Financial Modeling Prep MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
