AI agents call verify_address to retrieve information from GBG Loqate - Reach 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 verify_address 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.

Verify an address against Loqate's global reference data. Returns a confidence score (0-1), verification status, and a policy-driven accept/review/reject recommendation. Requires a Loqate API key — pass it via the 'key' field (get one at account.loqate.com).. It is categorised as a Read tool in the GBG Loqate - Reach MCP Server, which means it retrieves data without modifying state.
Register the GBG Loqate - Reach MCP server in PolicyLayer and add a rule for verify_address: 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 GBG Loqate - Reach. Nothing to install.
verify_address 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 verify_address 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 verify_address. 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.
verify_address is provided by the GBG Loqate - Reach MCP server (https://reach.prod.fabric.gbgplatforms.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
