Get distribution/occurrence information for a species
AI agents call get_distribution to retrieve information from MCP FishBase Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing data about where a species is found geographically. It performs a read-only query with no capability to modify, delete, execute code, or cause financial impact. The data returned is informational only. Consistent with sibling tools like 'get_ecology', 'get_morphology', and 'search_species', which are all read operations against a biological database.
From the tool's definition Tool name 'get_distribution' and description 'Get distribution/occurrence information for a species' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get distribution/occurrence information for a species. It is categorised as a Read tool in the MCP FishBase Server MCP Server, which means it retrieves data without modifying state.
Register the MCP FishBase Server MCP server in PolicyLayer and add a rule for get_distribution: 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 MCP FishBase Server. Nothing to install.
get_distribution 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_distribution 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_distribution. 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_distribution is provided by the MCP FishBase Server MCP server (lundgrenalex/mcp-fishbase). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_distribution is one line of MCP FishBase Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
