Part of the Chainflip Broker as a Service server.
Free to start. No card required.
AI agents invoke start_swap to trigger processes or run actions in Chainflip Broker as a Service. 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_swap 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.

These attack patterns abuse exactly the kind of access start_swap gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Start a cross-chain swap. Returns the deposit address where you should send your source asset. API key is optional.. It is categorised as a Execute tool in the Chainflip Broker as a Service MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Chainflip Broker as a Service MCP server in PolicyLayer and add a rule for start_swap: 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 Chainflip Broker as a Service. Nothing to install.
start_swap 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_swap 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_swap. 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_swap is provided by the Chainflip Broker as a Service MCP server (https://chainflip-broker.io/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
