  "description": "The official 1Password MCP lets an AI agent reference secrets stored in 1Password vaults — API keys, database passwords, SSH keys — without the secret values ever appearing in the conversation. Uses 1Password CLI-style secret references; the agent sees op://Vault/Item/field, the MCP resolves it at call time, and the cleartext goes directly to the downstream tool.",
