About Anvil

Through Operate As, your agent, n8n workflow or code works in Anvil with your client's own access. Your client pastes their API key from Anvil once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Anvil's API through the request tool, with the client's access attached.

Common uses in Files and docs

  • File documents where they belong
  • Read briefs, contracts and notes to act on
  • Share folders and keep versions in order
