gwas_top_hits
AI agents call gwas_top_hits to retrieve information from Tacc Mcp Bio without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'gwas_top_hits' strongly implies fetching or querying top results from a GWAS analysis, which is a Read operation. Given the server context of bioinformatics pipelines on HPC, this likely retrieves statistical results from a GWAS run. However, with no description, there is uncertainty — it could potentially trigger execution of a GWAS pipeline. Confidence is lowered due to the empty description.
From the tool's definition Tool name 'gwas_top_hits' suggests retrieval of top GWAS (Genome-Wide Association Study) results/hits, implying a read/query operation. However, the description is empty and uninformative.
Attacks that exploit this kind of access
gwas_top_hits. It is categorised as a Read tool in the Tacc Mcp Bio MCP Server, which means it retrieves data without modifying state.
Register the Tacc Mcp Bio MCP server in PolicyLayer and add a rule for gwas_top_hits: 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 Tacc Mcp Bio. Nothing to install.
gwas_top_hits 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 gwas_top_hits 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 gwas_top_hits. 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.
gwas_top_hits is provided by the Tacc Mcp Bio MCP server (narasimhan-lab/tacc-mcp-bio). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
