The Floor (FLOOR) indicator rounds input data down to the nearest integer, often used in conjunction with other indicators for data analysis or calculation purposes.
AI agents call GetTimeSeriesFloor 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.
This tool performs a read-only mathematical operation on data (flooring/rounding). It retrieves or transforms data without creating, modifying, deleting, or executing external operations. The verb 'Get' combined with a technical indicator function confirms it is a data retrieval and analysis tool with no capability to modify state or trigger side effects.
From the tool's definition Tool name 'GetTimeSeriesFloor' and description indicate it 'rounds input data down to the nearest integer' for 'data analysis or calculation purposes' — a pure mathematical transformation with no side effects.
Documented attack patterns abuse exactly the kind of access GetTimeSeriesFloor 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 GetTimeSeriesFloor:
{
"version": "1",
"default": "deny",
"tools": {
"GetTimeSeriesFloor": {}
}
}GetTimeSeriesFloor is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

The Floor (FLOOR) indicator rounds input data down to the nearest integer, often used in conjunction with other indicators for data analysis or calculation purposes. 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 GetTimeSeriesFloor: 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.
GetTimeSeriesFloor 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 GetTimeSeriesFloor 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 GetTimeSeriesFloor. 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.
GetTimeSeriesFloor 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.
