AI agents call get_functional_enrichment 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 retrieves and queries biological annotation data from the STRING database to return enrichment analysis results. It performs a read-only lookup operation that retrieves existing data without creating, modifying, deleting, or executing code. The only side effect is the computational analysis of input data, which is a standard query operation typical of bioinformatics analysis tools.
From the tool's definition Tool description: 'Get functional enrichment analysis for a list of proteins using STRING. Returns enriched GO terms, pathways, and domains.' The verb is 'Get' and the function returns analysis results (GO terms, pathways, domains) with no mention of data…
Attacks that exploit this kind of access
Get functional enrichment analysis for a list of proteins using STRING. Returns enriched GO terms, pathways, and domains. 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 get_functional_enrichment: 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.
get_functional_enrichment 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_functional_enrichment 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_functional_enrichment. 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_functional_enrichment 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.
