The Division (DIV) indicator performs arithmetic division between two input data series, typically used to combine or normalize multiple technical indicators or price data.
AI agents call GetTimeSeriesDiv 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 retrieves or derives technical indicator values through mathematical operations on existing time series data. It transforms data for analysis purposes without creating side effects, modifying underlying records, executing arbitrary code, or affecting financial accounts. The operation is purely computational and read-focused, consistent with the 'Read' category definition.
From the tool's definition Tool name 'GetTimeSeriesDiv' and description 'performs arithmetic division between two input data series, typically used to combine or normalize multiple technical indicators or price data' indicate a read-only calculation operation on financial market data.
Documented attack patterns abuse exactly the kind of access GetTimeSeriesDiv 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 GetTimeSeriesDiv:
{
"version": "1",
"default": "deny",
"tools": {
"GetTimeSeriesDiv": {}
}
}GetTimeSeriesDiv is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

The Division (DIV) indicator performs arithmetic division between two input data series, typically used to combine or normalize multiple technical indicators or price data. 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 GetTimeSeriesDiv: 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.
GetTimeSeriesDiv 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 GetTimeSeriesDiv 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 GetTimeSeriesDiv. 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.
GetTimeSeriesDiv 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.
