Withdraw collateral from a CDP — builds an unsigned transaction (CBOR hex) for client-side signing
Part of the Indigo Protocol MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use withdraw_cdp to initiate financial transactions through Indigo Protocol MCP. Financial operations involve real money and are irreversible once processed. Intercept blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.
withdraw_cdp moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. Intercept blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.
