Full-text search the ChEMBL drug-discovery database for molecules, targets, assays, or documents; returns ChEMBL IDs and summary fields you can pass to
AI agents call search 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 is a read-only query tool that searches a public drug discovery database and retrieves information. It has no side effects, does not modify data, does not execute code, and does not involve financial transactions. The blast radius of misuse is minimal—an agent might retrieve irrelevant scientific data, but cannot harm systems or data integrity.
From the tool's definition Tool performs 'Full-text search' and 'returns ChEMBL IDs and summary fields' with no mention of modification, deletion, or execution capabilities. The description explicitly indicates data retrieval only.
Attacks that exploit this kind of access
Full-text search the ChEMBL drug-discovery database for molecules, targets, assays, or documents; returns ChEMBL IDs and summary fields you can pass to. 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 search: 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.
search 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 search 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 search. 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.
search 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.
