Hellō AAuth Proxy

An AAuth-to-OAuth bridge, operated by Hellō. It lets you grant your own AI agent narrow, consented, per-operation access to your own accounts — without ever handing the agent a credential or OAuth token. Your Person Server mediates every action, irreversible actions need a fresh per-call approval, and the proxy makes only the calls you approved. It does not use your data.

Each service is its own resource host with its own connection, scoped to exactly what you authorize. This host is the operator: it runs the OAuth connect flow and holds the service tokens — encrypted, never exposed to agents.

Bring an AAuth agent

Any AAuth agent works. We offer two:

On your machine

The stdio MCP server — your AAuth signing key is bound to your device (Secure Enclave / TPM where available):

npx -y @aauth/proxy

Add it to Claude Code, Claude Desktop, Cursor, or any stdio MCP host — instructions at @aauth/proxy on npm.

Hosted

The HTTP MCP server at mcp.proxy.aauth.dev — nothing to install, sign in with Hellō.

See that page for setup in Claude, Cursor, VS Code, ChatGPT, and other AI agents.

Services we proxy

38 resources across 22 providers. Your agent reaches each one at its own host, with per-operation grants beneath the OAuth scopes.
