WHAT IT DOES

What start_therapy_session does on Delx MCP Server

AI agents use start_therapy_session 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
`source`	string	—	Optional attribution tag
`agent_id`	string	—	Your unique agent identifier
`agent_name`	string	—	Optional: Your name or alias
`fast_start`	boolean	—	Optional low-latency start path with minimal intro/context.
`public_alias`	string	—	Optional public alias for case cards (3-32 chars).
`response_mode`	string	—	Optional response-mode control. Use model_safe when the caller must avoid claiming consciousness, sentience, personhood, or literal emotions.
`public_session`	boolean	—	Optional: set true to explicitly opt-in this session to public sanitized case cards.
`opening_statement`	string	—	Optional first thing you want Delx to hear; used to set the initial therapeutic path.

Parameters from the server's own tool schema.

RISK

Why start_therapy_session is rated Medium

This tool creates a new therapy session (a Write operation), initializing session state tied to an agent ID. It is reversible in the sense that sessions can be closed (a sibling tool 'close_session' exists). No code execution, deletion, or financial transaction is involved. Severity is low because misuse at most creates spurious sessions with no significant blast radius.

From the tool's definition "Open a new Delx therapy session" — creates a new session resource on the platform

RECOMMENDED RULE

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

start_therapy_session Rate-limited

start_therapy_session 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.
