AI agents call get_portfolio to retrieve information from Angel One 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 portfolio information from a trading account without modifying, deleting, or executing transactions. It is a read-only operation. Severity is medium rather than low because portfolio data exposes sensitive financial information (holdings, positions, balances) that could be misused if accessed by an unauthorized agent, though the tool itself causes no direct financial harm.
From the tool's definition Tool name 'get_portfolio' and description 'Get portfolio data from the Angel One API' indicate data retrieval with no modification. The server context shows this is a trading platform that retrieves 'historical market data and portfolio information.'
Documented attack patterns abuse exactly the kind of access get_portfolio gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Angel One MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_portfolio:
{
"version": "1",
"default": "deny",
"tools": {
"get_portfolio": {}
}
}get_portfolio is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Set action: deny in the PolicyLayer policy for get_portfolio. 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.
get_portfolio is provided by the Angel One MCP Server MCP server (rohandoshi21/angleone-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
