Local auth for AI agents.

Log in once via OAuth2/API Key. Authsome keeps the credentials fresh for every AI agent.

Why Agents Are Different

Agents need API access that survives outside an interactive app:

• agents run without interactive sessions
• tokens expire, rotate, and need refresh
• tool access must work in scripts, cron, CI, SSH, background workers, and parallel pipelines

Hardcoded env tokens leak or go stale. DIY auth means rebuilding flow logic, token storage, refresh handling, expiry checks, and per-provider config for every project.

Authsome is the local credential layer agents can 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. No third-party cloud dependency.
• 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 in CI, SSH, cron, workers, or parallel pipelines.

How It Works

The CLI is the agent's interface: setup once, then inject fresh credentials whenever a tool runs.

┌──────────┐        authsome         ┌──────────────┐
│  Agent   │ ──────────────────────▶ │ Local Vault  │
└──────────┘                         └──────┬───────┘
     ▲                                      │
     │       fresh token / API key          │ encrypted
     └──────────────────────────────────────┘

Authenticate once:

uvx authsome login github

Then agents get valid credentials on demand:

uvx authsome get github --field access_token --show-secret
# → ghu_...

export $(uvx authsome export github)
# → sets GITHUB_ACCESS_TOKEN in current shell

uvx authsome run python my_agent.py
# runs behind a local auth proxy that injects headers at request time
# without exposing secrets in the child process environment.
# matched automatically via provider host_url (e.g. api.openai.com)

Credentials are stored locally, encrypted at rest, and refreshed before expiry. No server. No account. No cloud.

Why Authsome

	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.

Quick Start

uvx authsome login github                  # opens browser, completes PKCE flow
uvx authsome login github --flow device_code  # headless: Device Code, works over SSH and CI
uvx authsome login openai                  # secure API key entry via browser bridge
uvx authsome list                          # all connections + token status
