Retrieve the amino acid sequence of a protein by UniProt ID.
AI agents call get_protein_sequences 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 only fetches data from a public, read-only database resource. There are no write, delete, execute, or financial implications. The blast radius of misuse is minimal—an agent could only retrieve amino acid sequences it has UniProt IDs for, which is equivalent to normal database queries against public biological data.
From the tool's definition The tool 'Retrieve the amino acid sequence of a protein by UniProt ID' is explicitly a retrieval operation that queries the UniProt database.
Attacks that exploit this kind of access
Retrieve the amino acid sequence 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_sequences: 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_sequences 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_sequences 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_sequences. 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_sequences 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.
