THE RISK

Why get_substances_synonyms needs a policy

This is a straightforward data retrieval operation that queries a database of chemical substance identifiers and returns alternative names/identifiers for the same substance. It has no side effects, does not modify data, execute code, or affect external systems.

From the tool's definition Tool retrieves synonyms for a chemical substance by SID (Substance ID). The description explicitly states it 'gets' synonyms with no mention of modification, deletion, or execution of code/commands.

POLICY

How to control get_substances_synonyms

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

policy.json

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

get_substances_synonyms 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 OrigeneMCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
