THE RISK

Low Risk

Why signavio_search needs a policy

Search operations are read-only and retrieve existing data without side effects. This falls clearly into the Read category. The severity is low because full-text search has minimal blast radius—it cannot modify, delete, or execute actions. The confidence is high because the description explicitly indicates search functionality, which is a classic Read operation.

From the tool's definition Tool name 'signavio_search' and description 'Perform a full-text search across all content types' indicate a query/retrieval operation with no modification or deletion of data.

POLICY

How to control signavio_search

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "signavio_search": {}
  }
}

signavio_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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