record_chat_trace · MCPDischarge MCP: Risk & Policy

WHAT IT DOES

What record_chat_trace does on MCPDischarge

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

WHY IT NEEDS A POLICY

Why record_chat_trace needs a policy

This tool creates a new log record (a write operation). It stores a chat trace in a logging system. While PHI-safe (no raw user text), it still persists data. Severity is medium because misuse could result in incorrect or fabricated audit trails, which in a hospital context could have compliance and legal implications, though the PHI boundary enforcement limits direct patient data exposure.

From the tool's definition 'Record a PHI-safe chat trace' — actively writes/creates a log entry in the Logs UI

Verdict

record_chat_trace Rate-limited

record_chat_trace 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.
