AI agents call attom_property_search to retrieve information from Attom 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 attom_property_search 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.

"Find houses / homes / properties / real estate for sale or owned in [ZIP]" / "search properties near [coords]" / "homes in [neighborhood]" — search US residential and commercial properties by ZIP or lat/lng radius with filters (beds, baths, year built, property type). Returns matching addresses and ATTOM property IDs. Use first when you need to find candidate addresses, then call attom_property_detail / attom_avm / attom_sales_history on the picks.. It is categorised as a Read tool in the Attom MCP Server, which means it retrieves data without modifying state.
Register the Attom MCP server in PolicyLayer and add a rule for attom_property_search: 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 Attom. Nothing to install.
attom_property_search 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 attom_property_search 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 attom_property_search. 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.
attom_property_search is provided by the Attom MCP server (https://gateway.pipeworx.io/attom/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
