WHAT IT DOES

What bio.species does on Mcp

AI agents call bio.species to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why bio.species is rated Low

This is a straightforward read-only taxonomy lookup service. It queries an external knowledge base (GBIF) and returns structured information about organisms. No data is written, modified, deleted, or financial transactions triggered. The pay-per-call model affects billing, not the nature of the tool itself.

From the tool's definition Tool retrieves taxonomic data from GBIF backbone: 'accepted name, full lineage, vernacular names, global occurrence count, GBIF link.' Described action is 'Resolve' and 'Fuzzy-matches' — pure data lookup with no modification, creation, deletion, or external…

RECOMMENDED RULE

The rule that runs bio.species safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For bio.species, this is the rule to start with:

bio.species Allowed

bio.species is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bio.species": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every bio.species call is checked against it from then on.

FAQ

Questions about bio.species

What does the bio.species tool do? +

Resolve any organism (scientific or common name) to the GBIF taxonomic backbone: accepted name, full lineage (kingdom→species), vernacular names, global occurrence count, GBIF link. Fuzzy-matches misspellings. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on bio.species? +

Register the MCP server in PolicyLayer and add a rule for bio.species: 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. Nothing to install.

What risk level is bio.species? +

bio.species is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit bio.species? +

Yes. Add a rate_limit block to the bio.species 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.

How do I block bio.species completely? +

Set action: deny in the PolicyLayer policy for bio.species. 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.

What MCP server provides bio.species? +

bio.species is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
