AI agents call pdb_get_polymer_entity_groups to retrieve information from OrigeneMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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 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.
Documented attack patterns abuse exactly the kind of access pdb_get_polymer_entity_groups gives an agent:
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 pdb_get_polymer_entity_groups:
{
"version": "1",
"default": "deny",
"tools": {
"pdb_get_polymer_entity_groups": {}
}
}pdb_get_polymer_entity_groups is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

pdb_get_polymer_entity_groups. It is categorised as a Read tool in the OrigeneMCP MCP Server, which means it retrieves data without modifying state.
Register the Origene MCP server in PolicyLayer and add a rule for pdb_get_polymer_entity_groups: 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 OrigeneMCP. Nothing to install.
pdb_get_polymer_entity_groups is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the pdb_get_polymer_entity_groups 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.
Set action: deny in the PolicyLayer policy for pdb_get_polymer_entity_groups. 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.
pdb_get_polymer_entity_groups is provided by the Origene MCP server (gentel-lab/origenemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OrigeneMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
