vault_import · Secret Vault MCP Server MCP: Risk & Policy

WHAT IT DOES

What vault_import does on Secret Vault MCP Server

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

WHY IT NEEDS A POLICY

Why vault_import needs a policy

Import operations write/add data to the vault rather than read or delete it. The high severity reflects that importing secrets into encrypted storage could allow an attacker to inject malicious credentials or secrets if misused. Confidence is moderate (0.75) because the description is empty, limiting direct evidence; classification relies on contextual inference from the tool name and sibling tools' patterns.

From the tool's definition Tool name is 'vault_import' with no description provided. Based on sibling tools like vault_set, vault_update_tags, and vault_init which modify vault state, import functions typically load external data into a system.
