THE RISK

Medium Risk

Why report_field_corrections needs a policy

This tool modifies existing data by correcting field values (location, receiver parties) in provenance event records. It is a Write operation as it updates/corrects existing records rather than deleting them. The blast radius is medium since incorrect corrections could corrupt provenance data for artwork records, but the action appears reversible (corrections can be re-corrected).

From the tool's definition 'Report field-level corrections for provenance events with wrong/truncated location or missing receiver parties'

POLICY

How to control report_field_corrections

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_field_corrections:

policy.json

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

report_field_corrections 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about report_field_corrections

What does the report_field_corrections tool do? +

Report field-level corrections for provenance events with wrong/truncated location or missing receiver parties. 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_field_corrections? +

Register the Rijksmuseum Mcp+ MCP server in PolicyLayer and add a rule for report_field_corrections: 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_field_corrections? +

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

Can I rate-limit report_field_corrections? +

Yes. Add a rate_limit block to the report_field_corrections 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_field_corrections completely? +

Set action: deny in the PolicyLayer policy for report_field_corrections. 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_field_corrections? +

report_field_corrections 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.
