AI agents call proposeChartVariants 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.
This tool analyzes existing chart configurations and generates variant recommendations with scoring metadata. It retrieves and synthesizes information from a capability registry and heuristic discovery process, then returns structured proposals. No data is created, modified, deleted, or executed as a consequence—only informational variants are returned for human review.
From the tool's definition Tool "proposes and scores chart variants" with "returns ranked proposals with fit/novelty/risk scores, rationale, and ready-to-use props." The verb is 'Propose' (suggest), and output is read-only: scores, analysis, and prop suggestions with no side effects on…
Attacks that exploit this kind of access
Propose and score chart variants for a selected Semiotic component. Uses the capability registry plus heuristic variant discovery: registered variants, conservative transforms, and same-intent cross-family alternatives. Returns ranked proposals with fit/novelty/risk scores, rationale, and ready-to-use props. Use after suggestCharts when an agent wants to actively explore variants rather than stop at the first chart recommendation. It is categorised as a Read tool in the Semiotic MCP Server, which means it retrieves data without modifying state.
Register the Semiotic MCP server in PolicyLayer and add a rule for proposeChartVariants: 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.
proposeChartVariants 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 proposeChartVariants 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 proposeChartVariants. 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.
proposeChartVariants 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.
