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

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

## Why pdb_get_polymer_entity_groups is rated Low

This tool retrieves polymer entity group information from the Protein Data Bank. Despite the empty description reducing certainty, the naming convention and context of other biomedical query tools on this server strongly suggest read-only data retrieval with no side effects.

From the tool's own definition: "Tool name 'pdb_get_polymer_entity_groups' uses the 'get' verb, suggesting data retrieval. The PDB (Protein Data Bank) context and sibling tools (clinvar_query_*, depmap_get_*) consistently retrieve biomedical data without modification."

## Use case

AI agents call pdb_get_polymer_entity_groups 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": {
    "pdb_get_polymer_entity_groups": {}
  }
}
```
