WHAT IT DOES

What recognize_structure_image does on Scifinder Route

AI agents use recognize_structure_image to create or update resources in Scifinder Route — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Scifinder Route environment.

WHY IT NEEDS A POLICY

Why recognize_structure_image needs a policy

The tool performs two actions: it calls an external structure-recognition endpoint (Execute-like) and then registers/stores the resulting candidate SMILES in the database (Write). Since registration/storage is the primary side effect and it is reversible (records can be deleted), Write is the most appropriate category.

From the tool's definition 'register candidate SMILES' — the tool sends an image to an external endpoint and writes/registers the resulting SMILES into the system

Verdict

recognize_structure_image Rate-limited

recognize_structure_image stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Scifinder Route, so you can run agents against it safely.

FAQ

Questions about recognize_structure_image

What does the recognize_structure_image tool do? +

Send an image region to a configured MolScribe/DECIMER/OSRA-style endpoint and register candidate SMILES. It is categorised as a Write tool in the Scifinder Route MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on recognize_structure_image? +

Register the Scifinder Route MCP server in PolicyLayer and add a rule for recognize_structure_image: 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.

What risk level is recognize_structure_image? +

recognize_structure_image is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit recognize_structure_image? +

Yes. Add a rate_limit block to the recognize_structure_image 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.

How do I block recognize_structure_image completely? +

Set action: deny in the PolicyLayer policy for recognize_structure_image. 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.

What MCP server provides recognize_structure_image? +

recognize_structure_image 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.
