ovh_oauth2_initialize · Ovh MCP: Risk & Policy

WHAT IT DOES

What ovh_oauth2_initialize does on Ovh

AI agents invoke ovh_oauth2_initialize to trigger actions in Ovh. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ovh_oauth2_initialize needs a policy

This tool executes initialization code that authenticates against OVH's OAuth2 system and configures an API client. While not directly destructive or financial, it is an Execute-class operation because it triggers external authentication logic whose effects (API access scope, session creation, token generation) depend on the credentials provided.

From the tool's definition Tool name 'ovh_oauth2_initialize' and description 'Initialize OVH API client with OAuth2 credentials' indicate this tool executes authentication/initialization logic that sets up access to OVH API services.
