Sigcli

Sign in your way. AI works on your behalf.

AI agents need access to your work systems — Jira, wikis, calendars, internal APIs. But passing credentials through shell history, environment variables, and agent context windows is a security nightmare.

sig handles browser SSO, encrypts credentials at rest, and injects them into any process — so your agents authenticate without ever seeing secrets.

npm install -g @sigcli/cli

Quick Start

sig init                              # create ~/.sig/config.yaml
sig login https://jira.example.com    # authenticate via browser SSO — once

# now your AI agent can work on your behalf:
sig request https://jira.example.com/rest/api/2/myself
sig request https://jira.example.com/rest/api/2/search --method POST --body '{"jql":"assignee=currentUser()"}'

Why sig

• Browser SSO — signs in through a real browser. Works with any website, any login flow.
• Encrypted at rest — AES-256-GCM encryption. Every access is audit-logged.
• Multi-provider — inject credentials from multiple systems in a single command.
• MITM proxy — agents set HTTP_PROXY and credentials are injected transparently. Zero-trust.
• AI-native — stable CLI with predictable exit codes and JSON output. Built for agents.

How It Works

You log in once               sig stores & encrypts             AI agent operates
in your browser         -->   credentials locally          -->  on your behalf
(browser SSO)                 (~/.sig/credentials/)             (sig request / sig proxy)

AI Agent Skills

Pre-built Python scripts that let AI agents operate 14+ web services — email, chat, forums, video platforms, social networks, and more. Each skill includes scripts + documentation that agents read and execute autonomously.

git clone https://github.com/sigcli/sigcli.git
cd sigcli/skills && ./install.sh
