genome_summary_by_taxon
AI agents call genome_summary_by_taxon to retrieve information from Ncbi Datasets 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 genome summary information grouped by taxonomic category. It has no ability to modify, delete, or execute code. The action is purely informational—fetching public NCBI dataset metadata for reading.
From the tool's definition Tool name 'genome_summary_by_taxon' indicates retrieval of genome summary data filtered by taxonomic classification.
Attacks that exploit this kind of access
genome_summary_by_taxon. It is categorised as a Read tool in the Ncbi Datasets MCP Server, which means it retrieves data without modifying state.
Register the Ncbi Datasets MCP server in PolicyLayer and add a rule for genome_summary_by_taxon: 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 Ncbi Datasets. Nothing to install.
genome_summary_by_taxon 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 genome_summary_by_taxon 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 genome_summary_by_taxon. 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.
genome_summary_by_taxon is provided by the Ncbi Datasets MCP server (syntheticgio/ncbi-datasets-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
