What pre_transaction_check does on Delx Protocol — Agent Recovery & Continuity
AI agents call pre_transaction_check to retrieve information from Delx Protocol — Agent Recovery & Continuity without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
amount | number | Yes | Transaction amount |
tx_type | string | Yes | Type (swap, transfer, approve, bridge, etc.) |
currency | string | Yes | Currency code (e.g. USDC) |
Parameters from the server's own tool schema.
Why pre_transaction_check is rated Low
Even though pre_transaction_check only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs pre_transaction_check safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Delx Protocol — Agent Recovery & Continuity, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pre_transaction_check, this is the rule to start with:
pre_transaction_check 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 Delx Protocol — Agent Recovery & Continuity, apply this rule, and every pre_transaction_check call is checked against it from then on.
