Retrieve genome assembly metadata for one or more NCBI accessions.
AI agents call genome_summary_by_accession 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 queries and retrieves existing genome assembly metadata from NCBI without any capability to create, modify, delete, or execute operations. It is a straightforward data retrieval function with no side effects, fitting the Read category. Low severity is appropriate as misuse would only expose publicly available scientific data.
From the tool's definition Tool name 'genome_summary_by_accession' and description 'Retrieve genome assembly metadata' indicate a query/retrieval operation with no modification capability. The verb 'retrieve' and focus on 'metadata' confirm read-only semantics.
Attacks that exploit this kind of access
Retrieve genome assembly metadata for one or more NCBI accessions. 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_accession: 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_accession 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_accession 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_accession. 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_accession 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.
