How do I connect HashiCorp Vault to Claude or Cursor?

Connect HashiCorp Vault in Activepieces, enable the server under Settings → MCP Server, then paste your server URL into your client config. It authenticates over OAuth on first use.

What can my agent do in HashiCorp Vault?

It can call 5 tools, including Read Secret, Write Secret, Delete Secret, and chain them with steps in other apps inside the same run.

Is it safe to let an agent call HashiCorp Vault?

Connections use OAuth2 with limited scopes and are stored under 256-bit encryption, with no API to read them back, so an agent gets scoped access rather than your keys.
