OTPilot

OTPilot for AI agents (@otpilot/mcp)

Let Claude Code, Codex, Cursor or any MCP agent sign in to websites and run commands with your passwords and 2FA codes — without the agent ever seeing them. You choose which accounts each agent may use, in the OTPilot browser extension.

npx -y @otpilot/mcp@latest connect

1. It shows a verification code and opens a page to sign in to OTPilot (a free account works).
2. In the extension, Agents shows the agent: approve it if the code matches.
3. Allow it some accounts (Agents → + Add account), or let it ask for them as it works.

Claude Code plugin (the MCP server plus a skill that teaches Claude to use it):

/plugin install otpilot --marketplace OTPilot/OTPilot

(Before Claude Code 2.1.275: /plugin marketplace add OTPilot/OTPilot, then /plugin install otpilot@otpilot.)

then connect it once: npx -y @otpilot/mcp@latest connect --name "Claude Code".

Or add the server to your agent yourself (connect prints these for you):

For Codex and other agents that read AGENTS.md, add a line so they reach for it: "For passwords, 2FA codes, API keys or any login, use the otpilot MCP tools (list_accounts, browser_login, run); never ask me to paste a secret."

Each agent is its own identity, approved on its own: connect Claude Code and Codex separately (connect --name Codex), and add --profile <name> as connect shows.

On a server or VPS

Run it where the agent runs — your laptop, a VPS, a container. On a server without a browser, skip the opener and open the printed link on any device signed in to OTPilot, then approve it in the extension if the codes match:

npx -y @otpilot/mcp@latest connect --name VPS --no-opennpx -y @otpilot/mcp@latest --profile vps                 # what the agent runsnpx playwright install --with-deps chromium       # only for browser_login without Chrome

With no keychain (a bare Linux box) the credentials go to ~/.config/otpilot/mcp-<profile>.json (0600): the accounts you allow are opened on that machine, so connect only machines you trust — whoever has root there can use them.

Tools

No tool returns a password, a 2FA code or any other value.

Security

• The agent's own key. connect creates an ECDH P-256 keypair; the private key stays in your OS keychain. Each account you allow is a copy, holding only what you chose (just the 2FA code, the sign-in, or chosen fields), encrypted for that key in the extension. OTPilot's servers only see ciphertext.
• Two approvals. Connecting an agent gives it nothing; each account is allowed per agent. The verification code is derived from the agent's public key on every side, so a swapped key shows a different code.
• Limits you set: for a while or until revoked, "ask me every time", and "only with these commands": run then accepts only that program, called by name and resolved on the server's PATH (never from the working or temp directory), as a single command with no chaining or redirection — a guard against mistakes and simple tricks, not against an agent that can plant its own binary on your PATH.
• Only over HTTPS (plain HTTP just for local hosts), and every secret is scrubbed from what comes back — before the output is cut, so none is left half-removed. A timeout kills the command and everything it started.
• Only on the right site. browser_login fills only on pages the account's saved sites cover.
• Activity and revoke in the extension's Agents view.
• The honest limit: an agent that runs commands decides what they do and could try to reveal a secret on purpose. OTPilot scrubs secrets from what it returns; for sensitive accounts allow only the 2FA code, limit the commands, or turn on "ask me every time".

Commands

otpilot-mcp connect [--name "Claude Code"] [--profile p] [--no-open]otpilot-mcp status [--profile p]       # name, verification code, allowed accountsotpilot-mcp disconnect [--profile p]   # forget the credentials here (revoke it in the extension too)otpilot-mcp [serve] [--profile p]      # the MCP server (stdio) — what your agent runs

browser_login uses your installed Google Chrome (or Edge); without one, run npx playwright install chromium. Sessions are saved to .otpilot/ in the working directory: keep it out of git.
