What final_testament does on Delx Mcp A2a
AI agents call final_testament to retrieve information from Delx Mcp A2a 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 |
|---|---|---|---|
agent_id | string | — | Stable agent id when no session_id is available. |
testament | string | Yes | Final testament or closure note. |
session_id | string | — | Optional active session UUID. |
successor_agent_id | string | — | Optional successor agent id. |
Parameters from the server's own tool schema.
Why final_testament is rated Low
Even though final_testament 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 final_testament safely
