AI agents call get_chembl_release 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 queries and returns ChEMBL release information from a biomedical database. It performs no writes, deletes, code execution, or financial operations. The blast radius of misuse is minimal—an agent could only retrieve publicly available chemical/drug metadata, which poses no security or safety risk.
From the tool's definition Tool name 'get_chembl_release' and description 'Retrieve chembl_release object list' indicate a retrieval operation with no data modification or side effects. The verb 'retrieve' and the object type 'list' confirm read-only semantics.
Documented attack patterns abuse exactly the kind of access get_chembl_release 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 get_chembl_release:
{
"version": "1",
"default": "deny",
"tools": {
"get_chembl_release": {}
}
}get_chembl_release is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Retrieve chembl_release object list. 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 get_chembl_release: 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.
get_chembl_release 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 get_chembl_release 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 get_chembl_release. 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.
get_chembl_release 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.
