The Base-10 Logarithm (LOG10) indicator calculates the base-10 logarithm of a given input value, commonly used in advanced mathematical analysis or calculations in financial markets.
AI agents call GetTimeSeriesLog10 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 transformation on financial data. It does not create, modify, delete, or execute any operations that would alter state or trigger external actions. The logarithmic calculation is a common analytical transformation applied to financial indicators and returns a computed value without side effects.
From the tool's definition Tool description states it 'calculates the base-10 logarithm of a given input value' — a pure mathematical calculation with no side effects, data modification, or external state changes.
Documented attack patterns abuse exactly the kind of access GetTimeSeriesLog10 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 GetTimeSeriesLog10:
{
"version": "1",
"default": "deny",
"tools": {
"GetTimeSeriesLog10": {}
}
}GetTimeSeriesLog10 is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

The Base-10 Logarithm (LOG10) indicator calculates the base-10 logarithm of a given input value, commonly used in advanced mathematical analysis or calculations in financial markets. 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 GetTimeSeriesLog10: 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.
GetTimeSeriesLog10 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 GetTimeSeriesLog10 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 GetTimeSeriesLog10. 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.
GetTimeSeriesLog10 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.
