Fill stored secrets (passwords, card numbers, API keys) into web pages through the secure-browser MCP server without ever seeing the secret values. Use when a task needs a login, checkout, payment form, or any credential entered into a website and the credentials live in a secret store rather than in the conversation.
Use when working with Turnkey wallet infrastructure — creating wallets, signing blockchain transactions, managing users and policies, provisioning agents, or monitoring activities. Supports Ethereum/EVM, Solana, Bitcoin, and 10+ other chains. Keys stay in hardware-backed secure enclaves.
Day-0 onboarding workflow for Turnkey: verify API credentials, create your first wallet, and optionally test signing. Use for first-time setup; for agent provisioning, use provisioning-agent.
Manages Turnkey users, API keys, and user tags: create, update, and delete users; generate and rotate API keys; tag users for policy targeting; verify identity with whoami.
Monitors, approves, and rejects Turnkey activities (the result type for every submit endpoint): check status, list and filter activities, approve/reject for consensus workflows, and verify app proofs for audit. Includes patterns for root, admin, and automated agent approvers.
End-to-end workflow to give an AI agent a scoped Turnkey wallet: creates a wallet, a non-root agent user, and a wallet-scoped ALLOW policy, then verifies signing and outputs agent credentials. For day-2 operations, use managing-agent.
Signs and broadcasts blockchain transactions via Turnkey: EVM (Ethereum, Base, Polygon, Arbitrum, Optimism), Solana, Bitcoin, and any chain via raw payload signing. Includes gasless/sponsored transactions and message/typed-data signing.
