Retrieve the balance sheet for a given ticker symbol.
AI agents call get_balancesheet to retrieve information from MCPServerDemo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial data (balance sheet) for a ticker symbol without creating, modifying, deleting, or executing any operations. It is a straightforward read-only query. The sibling tools (get_cashFlows, get_profitLoss, get_quarterlyresults, get_Ratio) follow the same pattern.
From the tool's definition Tool name contains 'get_' and description states 'Retrieve the balance sheet' — both indicate data retrieval with no modification.
Attacks that exploit this kind of access
Retrieve the balance sheet for a given ticker symbol. It is categorised as a Read tool in the MCPServerDemo MCP Server, which means it retrieves data without modifying state.
Register the MCPServerDemo MCP server in PolicyLayer and add a rule for get_balancesheet: 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 MCPServerDemo. Nothing to install.
get_balancesheet 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 get_balancesheet 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 get_balancesheet. 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_balancesheet is provided by the MCPServerDemo MCP server (nitinudasin/mcpserverdemo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
