This endpoint is a lightweight method that allows retrieving only the real-time price of the selected instrument.
AI agents call GetPrice to retrieve information from Twelve Data MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
GetPrice retrieves financial market data (real-time price quotes) without any side effects—it does not create, modify, delete, execute code, or commit financial transactions. This is a pure data retrieval operation, fitting the Read category. While the data is financial in nature, the tool itself does not move money or create financial obligations; it only queries pricing information.
From the tool's definition Tool description states it is a 'lightweight method that allows retrieving only the real-time price of the selected instrument.' The verb 'retrieving' and the read-only nature of fetching current price data indicate no modifications, deletions, or external…
Documented attack patterns abuse exactly the kind of access GetPrice gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Twelve Data MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for GetPrice:
{
"version": "1",
"default": "deny",
"tools": {
"GetPrice": {}
}
}GetPrice is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

This endpoint is a lightweight method that allows retrieving only the real-time price of the selected instrument. It is categorised as a Read tool in the Twelve Data MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Twelve Data MCP Server MCP server in PolicyLayer and add a rule for GetPrice: 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 Twelve Data MCP Server. Nothing to install.
GetPrice 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 GetPrice 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 GetPrice. 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.
GetPrice is provided by the Twelve Data MCP Server MCP server (twelvedata/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
