Local-first credential broker and vault for AI Agents
Docs · Website · Discord · Issues
An open-source credential broker that sits between your agents and the services they call. Instead of sharing credentials with every agent, log in once via OAuth2 or API keys. Authsome stores credentials securely and injects them via an HTTP proxy. You get one place to manage access, rotate keys, and see what every agent is doing.
45 bundled providers out of the box: 14 OAuth2 and 31 API key. See the full list.

Agents run beyond interactive sessions. They live in CI, over SSH, in cron jobs, in background workers, and in parallel pipelines. They need API access that survives without a human in the loop.
Hardcoded environment tokens leak or go stale, and building auth flow logic, token storage, refresh handling, and per-provider config into every project rebuilds the same plumbing every time.
Authsome is the local credential layer agents call at runtime.
- No credential sprawl. One encrypted store. Every provider, every agent, one place.
- No SaaS, no privacy trade-off. Credentials never leave your machine. Eliminates credential exfiltration risks as agents never see them.
- No browser required at runtime. Setup can use browser PKCE, device code, or a browser bridge for secure API key entry. After that, agents run headlessly.
The CLI is the agent's interface: setup once, then inject fresh credentials whenever a tool runs.
Authenticate once:
authsome login github
# This opens a browser on user's machine
# user completes login without sharing the creds with the agent.Then agents get valid credentials on demand when they try to access external services.
All they need to do is use authsome run -- before the command they want to run:
authsome run -- curl -s "https://api.github.com/user/repos?per_page=10"
# runs behind a local auth proxy that injects headers at request time
# without exposing secrets in the child process environment.
# matched automatically via provider api_url (e.g. api.openai.com)Credentials are stored locally, encrypted at rest, and refreshed before expiry. No server. No account. No cloud.
| authsome | Hardcoded env tokens | DIY | |
|---|---|---|---|
| Automatic token refresh | ✅ | ❌ | build it |
| OAuth2 + API keys | ✅ | ❌ | build it |
| Runtime headless use | ✅ | ✅ | varies |
| Local, no SaaS dependency | ✅ | ✅ | ✅ |
| Built-in providers, zero config | ✅ | ❌ | ❌ |
| Multi-account per provider | ✅ | ❌ | build it |
Authsome gives agents one command for a valid token, without scattering long-lived secrets across every project.
Requires Python 3.13+.
uv tool install authsomeAdd the authsome skill to your agent (claude, codex, cursor, hermes, etc.):
npx skills add agentrhq/authsomeAnd try a sample task that requires access to external services:
Star the repo agentrhq/authsome
Get my last 5 emails from gmail
Check my stripe balance
The agent will use authsome to login into external services and perform the task.
Authsome ships with adapters for the most common agent frameworks and CLIs:

mint devAuthsome's daemon can emit product analytics through PostHog. You can disable telemetry with any of these environment variables:
DO_NOT_TRACK=1disables analytics using the standard opt-out convention.POSTHOG_DISABLED=1disables analytics using PostHog's recommended kill switch.AUTHSOME_ANALYTICS=0disables analytics with an Authsome-specific override.
