AI agents call search_uniprot to retrieve information from Gwas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the UniProt database to retrieve protein information based on search criteria. It has no side effects, does not modify data, and only retrieves existing biological information. This is a classic Read operation with minimal risk if misused by an AI agent—worst case being irrelevant search results or API rate limiting.
From the tool's definition Tool performs 'Search' operation that 'Returns protein function, sequence info, and associated genes' without modifying data. The verb 'Search' and 'Returns' indicate data retrieval only.
Attacks that exploit this kind of access
Search UniProt for protein information by protein name, gene name, or UniProt ID. Returns protein function, sequence info, and associated genes. It is categorised as a Read tool in the Gwas MCP Server, which means it retrieves data without modifying state.
Register the Gwas MCP server in PolicyLayer and add a rule for search_uniprot: 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 Gwas. Nothing to install.
search_uniprot 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_uniprot 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_uniprot. 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_uniprot is provided by the Gwas MCP server (muslus/gwas-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
