WHAT IT DOES

What wallet_sign_transaction does on Algorand MCP

AI agents invoke wallet_sign_transaction to trigger actions in Algorand MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why wallet_sign_transaction is rated High

Signing a transaction is a critical execution step that authorizes a blockchain operation. While signing alone doesn't submit the transaction, it produces a cryptographically authorized artifact that can be broadcast to commit funds or state changes on-chain.

wallet_sign_transaction Rate-limited

wallet_sign_transaction stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
