Retrieve structure information (PDB IDs) related to a protein by UniProt ID.
AI agents call get_protein_structures to retrieve information from UniProt MCP Server 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 protein structure metadata without modifying, executing, or deleting data. It has no side effects and presents minimal security risk as it returns publicly available scientific reference data. The blast radius of misuse is negligible—returning incorrect or excessive structure information causes no damage to systems, finances, or data integrity.
From the tool's definition Tool name 'get_protein_structures' and description 'Retrieve structure information' indicate data retrieval. The operation is explicitly a read-only query of existing protein structure data (PDB IDs) from the UniProt database.
Attacks that exploit this kind of access
Retrieve structure information (PDB IDs) related to a protein by UniProt ID. It is categorised as a Read tool in the UniProt MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UniProt MCP Server MCP server in PolicyLayer and add a rule for get_protein_structures: 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 UniProt MCP Server. Nothing to install.
get_protein_structures 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 get_protein_structures 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 get_protein_structures. 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.
get_protein_structures is provided by the UniProt MCP Server MCP server (vitamin3615/uniprot-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
