# 0283 — A browser-extension agent connector is deferred

> Deferred · 2026-10-22

> [!NOTE]
>
> Amends [0227](/adr/0227-rejected-and-deferred-technologies-refreshed.md): a row is added for a
> browser-extension agent connector, which is deferred. The table changes only by a new ADR, and
> 0283 is that ADR.

## Context

An agent can act inside the user's own browser through an extension: it reads the pages the user has open and clicks and types there, with
the user's signed-in sessions. Stackra's agents reach outside systems through server-side connectors and MCP tools
([0155](/adr/0155-queries-are-mcp-tools-and-all-ai-code-is-free.md), [0217](/adr/0217-api-surfaces-mcp-first-plus-rest-sdks-and-rate-limits.md)),
and browse in sandboxes. The owner decided on 2026-10-22 to defer a browser-extension connector.

## Decision

1. **Deferred.** No browser-extension agent connector is built or shipped: no extension, no bridge from the extension to `@stackra/ai`, and no
   agent tool that drives the user's browser.
2. **Use instead.** Server-side connectors and MCP tools for outside systems; Playwright in sandboxes when an agent must browse.
3. **The table.** [0227](/adr/0227-rejected-and-deferred-technologies-refreshed.md) carries the row, with this ADR as its source.

## Consequences

* An agent never acts with the user's browser sessions, so there is no extension to distribute, review or keep in step with browser stores.
* A task that only works inside a signed-in browser page is not automated until a connector or an API covers it.

## Enforcement

None yet. The deferral is a review check: a change that adds a browser extension or an agent tool that drives the user's browser needs a new
ADR first.

## Revival trigger

A paying customer needs in-browser automation.

## Supersedes and sources

Supersedes nothing. Amends [0227](/adr/0227-rejected-and-deferred-technologies-refreshed.md). Sources: owner decision, 2026-10-22 (STA-290).
