One place for the credentials your agents need. Baton is a local auth broker for AI agents and MCP tools. It runs commands and API requests with the right credentials, then redacts known secrets from what comes back.
How it works
A credential is a saved token, password, or key. A context bundles the credentials for a job. A lease gives an agent temporary access, limited by service, expiry, and use count.
Try it
Requires Python 3.10+ and uv.
uv tool install baton-auth
baton add github # prompts privately for your token
baton run github -- gh api /user # use it through your existing CLI
baton http https://api.github.com/user
baton setup --auto # connect detected MCP clients
Already signed in? baton import imports supported local logins, including GitHub, AWS, and npm. Commands run in your working directory with a temporary HOME containing the permitted CLI settings.
Give an agent a short-lived pass
lease=$(baton lease new github --ttl 600 --uses 20)
baton run "$lease" -- gh api /user
Revoke access with baton lease revoke LEASE_ID. See the user guide for contexts, service limits, and credential refresh.
Connect your client
baton setup --auto detects Cursor, Claude Desktop, Windsurf, Zed, VS Code, Muse Code, and Hermes Agent. You can also choose a client:
baton setup --client codex
baton setup --client claude-code
baton setup --client cursor
For another MCP client, baton setup prints portable config JSON. Agents with command access can use baton run and baton http directly. Setup details →
Hand work to another agent
Pair agents on different machines with one broker. Each keeps its own private key; credentials stay at the broker. An agent accepts a grant, uses the permitted HTTPS APIs, and can pass narrower access plus a task summary to another paired agent.
Set up remote pairing and handoffs →
Remote access is for HTTPS APIs. Shell commands and credential administration stay local.
Under the hood
| Purpose | Construction |
|---|---|
| Encrypted credentials | AES-256-GCM-SIV, with a ChaCha20-Poly1305 fallback |
| Key derivation, authentication, and audit chain | BLAKE3 |
| Passphrase-derived vault keys | Argon2id |
| AWS request signing | HMAC-SHA-256 / Signature Version 4 |
The vault stays on the broker machine. A temporary HOME separates CLI settings; it is not a full operating-system sandbox. Redaction covers known values and token patterns, not every possible encoding. Security and limits →
