## Why crm_exchange_token is rated Medium

This tool performs an OAuth token exchange, which creates new authentication tokens (access and refresh). This is a Write operation as it generates/creates new credentials in the OAuth system. The severity is high because misuse could result in unauthorized access token generation, potentially granting persistent access to CRM systems via refresh tokens.

From the tool's own definition: "Exchange an OAuth authorization code for access and refresh tokens"

## Use case

AI agents use crm_exchange_token to create or update resources in 0nmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 0nmcp environment.
