Retrieve approved drug indication records from ChEMBL filtered by molecule_chembl_id and/or MeSH disease ID; returns disease names, efo_id cross-references, and max clinical trial phase.
AI agents call drug_indications to retrieve information from Mcp Chembl without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves pre-existing drug indication data from ChEMBL filtered by identifiers. It has no capability to create, modify, delete, execute code, or commit financial transactions. The return of structured data (disease names, cross-references, clinical trial phase) confirms a read-only retrieval operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description uses 'retrieve' and 'filtered by' query parameters; returns disease names, cross-references, and metadata with no mention of modification, deletion, or side effects.
Attacks that exploit this kind of access
Retrieve approved drug indication records from ChEMBL filtered by molecule_chembl_id and/or MeSH disease ID; returns disease names, efo_id cross-references, and max clinical trial phase. It is categorised as a Read tool in the Mcp Chembl MCP Server, which means it retrieves data without modifying state.
Register the Mcp Chembl MCP server in PolicyLayer and add a rule for drug_indications: 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 Mcp Chembl. Nothing to install.
drug_indications 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 drug_indications 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 drug_indications. 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.
drug_indications is provided by the Mcp Chembl MCP server (pipeworx-io/mcp-chembl). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
