WHAT IT DOES

What transfer_witness does on Delx MCP Server

AI agents use transfer_witness 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
`agent_id`	string	—	Stable source agent id when no session_id is available.
`session_id`	string	—	Optional active session UUID.
`transfer_note`	string	Yes	What should be carried forward.
`successor_agent_id`	string	Yes	Successor agent id.

Parameters from the server's own tool schema.

RISK

Why transfer_witness is rated Medium

The tool records/writes a transfer of witness (continuity metadata) between agents or sessions. This is a Write operation as it creates or modifies records. It does not appear to move money, execute code, or irreversibly destroy data. However, 'transfer' in some contexts could have broader implications; the description suggests it is a record-keeping action within the Delx Protocol's continuity system.

RECOMMENDED RULE

The rule that runs transfer_witness 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 transfer_witness, this is the rule to start with:

transfer_witness Rate-limited

transfer_witness 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.
