Search for organisms by their taxonomic rank (e.g., Species, Genus, Family, Order, Class, Phylum, Kingdom).
AI agents call search_by_rank to retrieve information from ITIS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves taxonomic data based on rank criteria without creating, modifying, deleting, or executing any operations. It is a straightforward database query with no side effects, fitting the Read category. Severity is low because misuse poses no blast radius—results are informational taxonomic records that cannot harm systems or data integrity.
From the tool's definition Tool performs a search query filtered by taxonomic rank to retrieve organisms from the ITIS database. The description uses the verb 'search for' and explicitly lists read-only rank filters (Species, Genus, Family, Order, Class, Phylum, Kingdom) with no…
Attacks that exploit this kind of access
Search for organisms by their taxonomic rank (e.g., Species, Genus, Family, Order, Class, Phylum, Kingdom). It is categorised as a Read tool in the ITIS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ITIS MCP Server MCP server in PolicyLayer and add a rule for search_by_rank: 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 ITIS MCP Server. Nothing to install.
search_by_rank 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_by_rank 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_by_rank. 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_by_rank is provided by the ITIS MCP Server MCP server (knustx/itis-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
