Search the compound registry by name, CAS, SMILES, or InChIKey.
AI agents call search_compounds to retrieve information from Scifinder Route without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from a compound registry without creating, modifying, deleting, or executing any operations. It is a straightforward read-only search function. The low severity reflects minimal blast radius—misuse would return unwanted search results but cause no data loss, financial impact, or system compromise.
From the tool's definition Tool name 'search_compounds' and description 'Search the compound registry by name, CAS, SMILES, or InChIKey' indicate a query/retrieval operation with no modification or execution of external operations.
Attacks that exploit this kind of access
Search the compound registry by name, CAS, SMILES, or InChIKey. It is categorised as a Read tool in the Scifinder Route MCP Server, which means it retrieves data without modifying state.
Register the Scifinder Route MCP server in PolicyLayer and add a rule for search_compounds: 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 Scifinder Route. Nothing to install.
search_compounds 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_compounds 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_compounds. 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_compounds is provided by the Scifinder Route MCP server (kettly1260/scifinder-route-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
