Returns a list of available time intervals for data requests.
AI agents call GetIntervals 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 and returns informational data (available time intervals) with no side effects, modifications, or external execution. It is a simple query/list operation used for discovering API capabilities, making it a Read category tool with low severity.
From the tool's definition Tool name 'GetIntervals' and description 'Returns a list of available time intervals for data requests' indicate a retrieval operation that queries metadata about available intervals without modifying or executing any operations.
Documented attack patterns abuse exactly the kind of access GetIntervals 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 GetIntervals:
{
"version": "1",
"default": "deny",
"tools": {
"GetIntervals": {}
}
}GetIntervals is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns a list of available time intervals for data requests. 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 GetIntervals: 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.
GetIntervals 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 GetIntervals 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 GetIntervals. 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.
GetIntervals 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.
