A local MCP server for AI agents to use existing Chrome tabs, with signed owner approvals.
View on GitHub ↗Gaddi is a local MCP server that lets AI agents work in your existing Chrome tabs.
Agents use your existing logins, open background task groups, read pages and interact with controls.
I built it to work with MCP-capable agents without taking focus from my other apps.
OmniRead is Gaddi’s reading companion. Gaddi captures the page in your signed-in tab; OmniRead extracts Markdown, indexes its sections and reports evidence of missing content. Together, an agent can read a subscriber article, request one section and distinguish a full capture from an abstract or blocked page. A completeness verdict is evidence, not a guarantee.
A held action waits for you to confirm it in Gaddi's Mac panel. Telling the agent "yes" does not create that signature.
A local broker checks each request before Chrome. The default policy holds recognized payments, purchases, deletion, security changes and sends, plus all uploads. Gmail Send and direct password-field access are refused.
The panel names the action and can show its target. Touch ID or your Mac password authorizes a Secure Enclave key to sign your decision. Approval binds to the pending action; changed requests and reused proofs fail. The button labelled “Approve with Touch ID” also accepts the Mac password. There is no software-key fallback.
Sign-ins and eligible sends can remember a site after a signed decision. The shipped lists are empty. Payments, deletion, security actions and uploads cannot be remembered. See authorization details.
