1password vs XNotepad AI
A side-by-side look at the 1password and XNotepad AI MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose 1password for security work as a local process; choose XNotepad AI for knowledge & memory. You can also run both side by side in one mcpServers block.

Tools & capabilities
1password tools 15
vault_listList the 1Password vaults accessible to the service account (limited to the allow-listed vaults when OP_MCP_ALLOWED_VAULTS / --allowed-vaults is configured). Returns vault IDs, names, descriptions, and types.item_lookupSearch for items within a 1Password vault by title substring. Returns item IDs, titles, categories, and vault IDs.item_deletePermanently delete an item from a 1Password vault. This action cannot be undone.item_getRetrieve a full 1Password item — title, category, tags, notes, and all fields (id, title, type, section). Secret-bearing field values (passwords and other concealed fields, SSH private keys, one-time-password seeds, card numbers) are hidden unless reveal is true; only known non-secret types (text, URL, email, phone, date, menu, card type, address, reference) are shown by default. Accepts a secret reference (op://vault/item/field) or vault ID + item ID. Revealing a secret puts it in the model context/transcript — to USE a secret in a command or API call, prefer op_run with op:// references instead.item_editEdit an existing 1Password item. Update the title, notes (pass an empty string to clear notes), tags, website URL, upsert fields, or remove fields. Only referenced fields are changed; all others are preserved.item_listList all items in a 1Password vault, returning id, title, category, tags, and updatedAt for each. Never returns secret values.item_archiveArchive an item in a 1Password vault. The item is moved to the archive and hidden from regular views, rather than being permanently deleted.note_createCreate a Secure Note item in a 1Password vault, with optional tags and custom fields.password_createCreate a new password/login item in a 1Password vault with optional username, URL, tags, and notes.password_readRetrieve a secret from 1Password using either a secret reference (op://vault/item/field) or vault ID + item ID. Supports field selection and optional value reveal (defaults to metadata-only). Revealing a secret puts it in the model context/transcript — to USE a secret in a command or API call, prefer op_run with op:// references instead.
