WHAT IT DOES

What close_sp_account does on Indigo Protocol MCP

AI agents use close_sp_account to create or update resources in Indigo Protocol MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Indigo Protocol MCP environment.

Parameter	Type	Required	Description
`address`	string	—	User Cardano bech32 address
`accountTxHash`	string	—	Transaction hash of the account UTxO
`accountOutputIndex`	number	—	Output index of the account UTxO

Parameters from the server's own tool schema.

RISK

Why close_sp_account is rated Medium

This tool creates a reversible state change (closes account and withdraws funds) but the account can be reopened and funds can be redeposited, making it Write rather than Destructive. Severity is high because it moves user assets and affects account state, but the transaction must be signed by the client before execution, limiting immediate blast radius from agent misuse.

From the tool's definition Tool closes an account ('Close a stability pool account') and withdraws deposited iAssets ('withdraw all deposited iAssets'). It returns an unsigned transaction, indicating the action modifies blockchain state but does not execute autonomously.

RECOMMENDED RULE

The rule that runs close_sp_account safely

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

close_sp_account Rate-limited

close_sp_account stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
