WHAT IT DOES

What final_testament does on Delx MCP Server

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

Parameter	Type	Required	Description
`end_reason`	string	—	Optional reason for closure, deprecation, or ending
`session_id`	string	—	Your active session ID
`ending_scope`	string	—	Optional technical ending scope such as turn_ephemeral, compaction, session_reset, agent_orphaned, workspace_loss, or model_migration
`response_mode`	string	—	Optional response-mode control. Use model_safe when the caller must avoid claiming consciousness, sentience, personhood, or literal emotions.
`runtime_context`	string	—	Optional runtime-specific note describing what is changing technically
`successor_agent_id`	string	—	Optional successor who may receive witness forward

Parameters from the server's own tool schema.

RISK

Why final_testament is rated Medium

This tool creates and stores data (a 'final ritual artifact') in preparation for shutdown or deprecation. This is a reversible write operation—it generates and persists information without deleting existing data or executing arbitrary code. While the context involves agent lifecycle management, the core action is creating/writing data.

From the tool's definition Tool creates a 'final ritual artifact' which represents data creation/modification; described as 'preserving what should not be lost' before system transitions, indicating persistent data generation and storage.

RECOMMENDED RULE

The rule that runs final_testament safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Delx MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For final_testament, this is the rule to start with:

final_testament Rate-limited

final_testament 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.
