WHAT IT DOES

What wallet_add_account does on Algorand MCP

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

RISK

Why wallet_add_account is rated Medium

This tool creates and persists new blockchain accounts, which is a reversible write operation. While account creation itself is Write-category, the high severity reflects that compromised account creation in a financial blockchain context (Algorand) could facilitate unauthorized fund transfers or asset control.

From the tool's definition Tool creates a new Algorand account and stores it in the agent-wallet database, evidenced by phrases: 'Create a new Algorand account', 'store it in the agent-wallet database', and 'auto-switch to it'. This is data creation and modification.

RECOMMENDED RULE

The rule that runs wallet_add_account safely

wallet_add_account Rate-limited

wallet_add_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.
