Conversational interrogation of a Semiotic chart. Extract a statistical summary and answer natural language questions about the data, trends, and outliers. Returns a summary and guidance for an AI to generate a textual answer and visual annotations.
AI agents call interrogateChart to retrieve information from Semiotic without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It has no side effects—it does not create, modify, delete, execute code, move money, or trigger external operations.

Register the Semiotic MCP server in PolicyLayer and add a rule for interrogateChart: 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 Semiotic. Nothing to install.
interrogateChart 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 interrogateChart 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 interrogateChart. 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.
interrogateChart is provided by the Semiotic MCP server (semiotic). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
