WHAT IT DOES

What swap does on Twofold

AI agents call swap as a supporting operation in Twofold workflows.

RISK

Why swap is rated Low

Without any rule in front of it, every call an agent makes to swap happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs swap safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Twofold, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For swap, this is the rule to start with:

swap Rate-limited

swap gets a rate cap, and everything else on the server is denied unless you say otherwise.

FAQ

Questions about swap

What does the swap tool do? +

Swap through a Twofold pool from the MCP wallet: quotes first, executes with a real minimum-out. It is categorised as a Other tool in the Twofold MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on swap? +

Register the Twofold MCP server in PolicyLayer and add a rule for 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 Twofold. Nothing to install.

What risk level is swap? +

swap is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit swap? +

Yes. Add a rate_limit block to the 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.

How do I block swap completely? +

Set action: deny in the PolicyLayer policy for 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.

What MCP server provides swap? +

swap is provided by the Twofold MCP server (twofold-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
