DeepSeek Harness Connector — by Corsen AI

Let an exact DeepSeek Harness session operate tabs you choose, in your own signed-in Chrome. Local, unofficial, by Corsen AI.

DeepSeek Harness Connector lets one exact DeepSeek Harness session — running on your own computer — read and act in the browser tabs you explicitly attach to it, inside the Chrome profile you are already signed in to. No hidden automation browser, no guessing which tab belongs to which task. HOW IT WORKS 1. Install the companion into a DeepSeek Harness profile with the one dsh plugin add command the panel shows for your version — it downloads the companion from the project's release page 2. Start DeepSeek Harness — the connector starts its local broker by itself — and print the pairing code: dsh plugin --profile web exec dsh-connector-broker --pairing-code 3. Type that code once into this extension's side panel. Its setup card says whether the connector is reachable and shows these commands for your system. 4. Pick a session, open the tab you want it to work in, and press "Attach". The panel always shows the route in plain words: DeepSeek session → Chrome profile → attached tabs. If an action cannot run, the panel says why — not paired, no session selected, no tab attached, connector unreachable, versions mismatched. WHAT A SESSION CAN DO IN ITS TABS Read the visible page as structured text, take a screenshot of it, find text, click, type, press keys, scroll, hover, choose options, drag, navigate, go back and forward, reload, and open, list, switch, and close tabs — only within the tabs you attached to that session. WHAT IT NEVER DOES • Never reads or acts in a tab you did not attach. Attachment is explicit and per session. • Never reads your cookies, history, bookmarks, or saved passwords — those permissions are not requested. • Passwords, one-time codes, payment fields, and hidden values are masked inside the page, before anything leaves the browser. A screenshot, taken only when the session asks for one, shows the page as you see it: pixels are not masked. • Never sends anything to Corsen AI. The extension talks only to the connector on your computer (127.0.0.1); page content goes from there to your own DeepSeek Harness, and onward only to the model provider you configured it with. • Never claims an action happened when the browser refused it. A closed tab, an invalid form, a page that navigated away — each is reported for what it was. EXACT ROUTING Every browser action carries the identity of the session that asked for it and reaches one bound tab. Two sessions, two projects, or two Chrome profiles running at the same time never act in each other's tabs. A session with no attached tab gets a refusal, never someone else's page.
