AI agents call get_term_info to retrieve information from VirtualFlyBrain without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_term_info only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_term_info gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Get term information from VirtualFlyBrain using one or more VFB IDs. Supports batch requests — pass an array of IDs to fetch multiple terms in parallel. When multiple IDs are provided, results are returned as a JSON object keyed by ID. The Images field is keyed by template brain ID — use these to construct VFB browser URLs: https://v2.virtualflybrain.org/org.geppetto.frontend/geppetto?id=<VFB_ID>&i=<TEMPLATE_ID>,<IMAGE_ID1>,<IMAGE_ID2> where id= is the focus term and i= is a comma-separated list of image IDs for the 3D viewer (template ID must be first in the i= list to set the coordinate space).. It is categorised as a Read tool in the VirtualFlyBrain MCP Server, which means it retrieves data without modifying state.
Register the VirtualFlyBrain MCP server in PolicyLayer and add a rule for get_term_info: 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 VirtualFlyBrain. Nothing to install.
get_term_info 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_term_info 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_term_info. 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_term_info is provided by the VirtualFlyBrain MCP server (https://vfb3-mcp.virtualflybrain.org). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
