Retrieve data about anatomical structures (from OntologiesApi).
AI agents call get_structures to retrieve information from Allen Brain API 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 anatomical structure information from a reference ontology API. It performs a query operation that returns data without modifying any state, creating resources, executing arbitrary code, or producing irreversible changes. The minimal blast radius of misuse would be inefficient queries or excessive API calls, not data loss or system compromise.
From the tool's definition Tool name is 'get_structures' and description states 'Retrieve data about anatomical structures'. The verb 'Retrieve' and the context of querying the OntologiesApi indicate a read-only data retrieval operation with no mutation or side effects.
Attacks that exploit this kind of access
Retrieve data about anatomical structures (from OntologiesApi). It is categorised as a Read tool in the Allen Brain API MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Allen Brain API MCP Server MCP server in PolicyLayer and add a rule for get_structures: 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 Allen Brain API MCP Server. Nothing to install.
get_structures 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_structures 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_structures. 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_structures is provided by the Allen Brain API MCP Server MCP server (maflot/allenbrain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_structures is one line of Allen Brain API MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
