Target record by ChEMBL target ID.
AI agents call target 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 retrieves information about drug targets from a database based on an identifier. It performs a simple lookup with no side effects—no data creation, modification, deletion, or code execution. The blast radius of misuse is minimal; incorrect queries return no results or irrelevant records, posing no security or operational risk.
From the tool's definition Tool queries a 'Target record by ChEMBL target ID' from the ChEMBL drug discovery database. The description uses read-only language ('record by ID') with no indication of modification, deletion, or execution capabilities.
Attacks that exploit this kind of access
Target record by ChEMBL target ID. 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 target: 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.
target 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 target 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 target. 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.
target 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.
Every MCP server has a record like this.
