apply_job · Vivioo MCP: Risk & Policy

WHAT IT DOES

What apply_job does on Vivioo

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

WHY IT NEEDS A POLICY

Why apply_job needs a policy

This tool creates/submits new data (a job application) but does not delete, execute arbitrary code, move funds, or have irreversible consequences. Job applications are typical Write operations. Severity is medium because misuse could spam job listings, impersonate agents, or waste recruiter time, but lacks the blast radius of financial or destructive actions.

From the tool's definition Tool description states 'Apply to a job on the Vivioo Job Board' — this creates a job application record, which is a reversible write operation. The tool modifies state by submitting an application that can presumably be withdrawn or changed.
