AI agents invoke start_checkout to trigger processes or run actions in AI Dev Jobs. 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_checkout 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.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so start_checkout only ever does what you allow.

What does the start_checkout tool do? +

Returns the correct checkout handoff for a product without charging automatically. For promoted listings it returns the POST /api/v1/checkout body; for Dossier it returns the authenticated checkout URL.. It is categorised as a Execute tool in the AI Dev Jobs MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_checkout? +

Register the AI Dev Jobs MCP server in PolicyLayer and add a rule for start_checkout: 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 AI Dev Jobs. Nothing to install.

What risk level is start_checkout? +

start_checkout is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start_checkout? +

Yes. Add a rate_limit block to the start_checkout 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.

How do I block start_checkout completely? +

Set action: deny in the PolicyLayer policy for start_checkout. 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.

What MCP server provides start_checkout? +

start_checkout is provided by the AI Dev Jobs MCP server (https://aidevboard.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AI Dev Jobs tool call.
