What is the 1password MCP Server?

MCP server for 1Password service accounts

The short version

Built on the MCP TypeScript SDK v2 with protocol negotiation for 2026-07-28 (and legacy clients). Secrets stay in 1Password; agents prefer op:// references and op_run so plaintext never has to land in the model transcript.

  • Security-first defaults — — password_read and item_get return metadata unless you opt in with reveal: true
  • op_run (the MCP equivalent of op run) — — inject op://vault/item/field into a local command’s environment; plaintext is redacted from stdout/stderr and never logged back to the model
  • Full vault toolkit — — list, search, get, edit, create logins & notes, rotate passwords, archive, or delete
  • Guided prompts — — password generation, credential rotation, vault audit, and secret-reference helpers
  • Browsable resources — — vault and item catalogs over 1password://… URIs (no secrets in resource payloads)
  • Modern MCP — — stdio transport, Zod 4 schemas, MCP the publisher’s release record negotiation with legacy client compatibility
