Why report_structural_signals needs a policy

The tool appears to submit/report analytical findings (structural signals from unknown provenance segments) into some classification or audit system. This is a write-type operation as it creates new records or updates classification data. The description is somewhat opaque, lowering confidence.

From the tool's definition 'Report structural signals' and 'could enable deterministic classification' — the tool reports/submits findings, implying a write operation that creates or modifies records in the system.

POLICY

How to control report_structural_signals

PolicyLayer is an MCP gateway — it sits between your AI agents and Rijksmuseum Mcp+, and nothing reaches the server without passing your rules. This is the rule we recommend for report_structural_signals:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "report_structural_signals": {
      "limits": [
        {
          "counter": "report_structural_signals_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

report_structural_signals stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Rijksmuseum Mcp+ — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about report_structural_signals

What does the report_structural_signals tool do? +

Report structural signals found in unknown provenance segments that could enable deterministic classification. It is categorised as a Write tool in the Rijksmuseum Mcp+ MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on report_structural_signals? +

Register the Rijksmuseum Mcp+ MCP server in PolicyLayer and add a rule for report_structural_signals: 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 Rijksmuseum Mcp+. Nothing to install.

What risk level is report_structural_signals? +

report_structural_signals is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit report_structural_signals? +

Yes. Add a rate_limit block to the report_structural_signals 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.

How do I block report_structural_signals completely? +

Set action: deny in the PolicyLayer policy for report_structural_signals. 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.

What MCP server provides report_structural_signals? +

report_structural_signals is provided by the Rijksmuseum Mcp+ MCP server (kintopp/rijksmuseum-mcp-plus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
