AI agents call property_basic_history to retrieve information from Attom without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical information about property basics (likely ownership, deed records, or prior assessments). The verb 'Get' confirms it is a read-only query operation with no side effects. The ATTOM API context (real estate data provider) supports this as a lookup/retrieval tool. No data is modified, deleted, or financial transactions are initiated.
From the tool's definition Tool name 'property_basic_history' and description 'Get property basic history information' indicate data retrieval with no modification, deletion, or execution of operations.

Get property basic history information. 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 property_basic_history: 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.
property_basic_history 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 property_basic_history 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 property_basic_history. 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.
property_basic_history is provided by the Attom MCP server (nkbud/mcp-server-attom). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
