## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_cids_by_formula",
    "arguments": {}
  }
}
```

## Why get_cids_by_formula is rated Low

This is a straightforward query tool that searches a chemical database (PubChem CIDs) by molecular formula and returns matching identifiers. No data is modified, deleted, or executed—it purely retrieves information. The risk is minimal as misuse would only return irrelevant chemical data, with no side effects on the system or data integrity.

From the tool's own definition: "Tool name 'get_cids_by_formula' and description 'Get a list of CIDs by molecular formula' indicate retrieval of compound identifiers based on a query parameter."

## Use case

AI agents call get_cids_by_formula to retrieve information from OrigeneMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches OrigeneMCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_cids_by_formula": {}
  }
}
```
