AI agents invoke start_customer_verification to trigger processes or run actions in TaskMan of London. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
start_customer_verification can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Use when an existing customer wants to verify identity (OTP or magic link) before assistant-led booking.. It is categorised as a Execute tool in the TaskMan of London MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the TaskMan of London MCP server in PolicyLayer and add a rule for start_customer_verification: 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 TaskMan of London. Nothing to install.
start_customer_verification is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the start_customer_verification 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 start_customer_verification. 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.
start_customer_verification is provided by the TaskMan of London MCP server (https://taskman.london/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
