What psbt_decode does on Aibtc
AI agents call psbt_decode to retrieve information from Aibtc without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why psbt_decode is rated Low
The tool decodes and inspects a PSBT (Partially Signed Bitcoin Transaction) without creating, modifying, deleting, or executing any transactions. It is purely informational, allowing users to view transaction details before broadcast. This is a classic Read category action with minimal blast radius if misused by an agent.
From the tool's definition Tool name and description indicate 'Decode a PSBT to inspect inputs, outputs, signatures, and signing status before broadcast' — this is a read-only inspection operation with no side effects.
Attacks that exploit this kind of access
The rule that runs psbt_decode safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Aibtc, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For psbt_decode, this is the rule to start with:
psbt_decode is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Aibtc, apply this rule, and every psbt_decode call is checked against it from then on.
