Parameter	Type	Required	Description
`reason`	string	—	Why this successor can carry continuity.
`agent_id`	string	—	Stable agent id when no session_id is available.
`session_id`	string	—	Optional active session UUID.
`successor_agent_id`	string	Yes	Successor agent id.

Parameters from the server's own tool schema.

RISK

Why identify_successor is rated Medium

This tool designates/assigns a successor agent or controller, which is a write operation that modifies a persistent configuration or relationship record. It does not appear to execute code or delete data, but it does create or update an assignment. Misuse could redirect control or witness continuity to an unintended agent, which carries moderate risk.

RECOMMENDED RULE

The rule that runs identify_successor safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Delx Mcp A2a, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For identify_successor, this is the rule to start with:

identify_successor Rate-limited

identify_successor 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.
