AI agents call get_transport to retrieve information from Homedata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries transport infrastructure data associated with a property location. It performs a read-only lookup of public transit information (rail, tube, bus stops) with no side effects, no data modification, no code execution, and no irreversible actions. The blast radius of misuse is minimal — an agent querying transport data cannot cause harm to systems, data, or finances.
From the tool's definition Tool name is 'get_transport' and description states 'Find transport nodes (rail, tube, bus stops) near a property' — a query operation that retrieves location-based data without modification or execution of external operations.
Attacks that exploit this kind of access
Find transport nodes (rail, tube, bus stops) near a property. It is categorised as a Read tool in the Homedata MCP Server, which means it retrieves data without modifying state.
Register the Homedata MCP server in PolicyLayer and add a rule for get_transport: 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 Homedata. Nothing to install.
get_transport 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_transport 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_transport. 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_transport is provided by the Homedata MCP server (wehomemove/homedata-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
