Retrieve the functional annotations of a protein by UniProt ID.
AI agents call get_protein_functions 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 and queries functional annotation data from the UniProt database. There are no indications of data creation, modification, deletion, code execution, or financial impact. The operation is purely informational—it fetches existing protein function information by UniProt ID. The blast radius of misuse is minimal, as reading public biological databases poses no inherent risk.
From the tool's definition Tool name 'get_protein_functions' and description 'Retrieve the functional annotations of a protein' indicate a read-only operation that queries and returns protein function data without modification or side effects.
Attacks that exploit this kind of access
Retrieve the functional annotations of 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_functions: 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_functions 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_functions 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_functions. 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_functions 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.
