Keys

Causalist runs in your browser. Your API keys are stored only in this device’s localStorage, sent directly to Anthropic and GitHub, and never touch our servers.

Anthropic API key

Used for Structure / Dependency / Semantic / Oracle agents. Claude Opus 4.7.

Get one at console.anthropic.com/settings/keys.

GitHub token

Required to analyze private repos. Public repos work without one.

Create a fine-grained token with repo read access at github.com/settings/personal-access-tokens.

Keys live in browser storage only. Analyze requests call api.anthropic.com and api.github.com directly from your browser. Nothing is stored server-side.
