Assess drug-likeness using Lipinski Rule of Five, Veber rules, and PAINS filters
AI agents call assess_drug_likeness to retrieve information from PubChem MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs computational analysis and property assessment on chemical compounds. It evaluates molecular properties against standard pharmaceutical rules (Lipinski Rule of Five, Veber rules, PAINS filters) and returns analytical results. This is a read-only operation that retrieves or analyzes existing data with no side effects, data modification, or system-level operations.
From the tool's definition Tool name 'assess_drug_likeness' and description 'Assess drug-likeness using Lipinski Rule of Five, Veber rules, and PAINS filters' indicate analysis and evaluation of molecular properties against established pharmaceutical criteria.
Attacks that exploit this kind of access
Assess drug-likeness using Lipinski Rule of Five, Veber rules, and PAINS filters. It is categorised as a Read tool in the PubChem MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PubChem MCP Server MCP server in PolicyLayer and add a rule for assess_drug_likeness: 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 PubChem MCP Server. Nothing to install.
assess_drug_likeness 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 assess_drug_likeness 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 assess_drug_likeness. 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.
assess_drug_likeness is provided by the PubChem MCP Server MCP server (k-lordbodin7/pubchem-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
