Overview
- What it is — Interceptor is a CLI-driven tool that gives AI agents human-style control of the user's real Chrome/Brave browser (via a Chrome extension) and native macOS apps (via a Swift bridge daemon), without spinning up a separate automated browser.
- Problem — Most browser automation stacks start a separate browser, immediately losing authenticated sessions and cookies; Interceptor routes agent commands into the user's existing logged-in browser, preserving all context and bypassing detection.
- Who it's for — Developers and AI agent builders who need agents to automate web workflows using the user's real browser sessions, or drive native macOS applications via the same unified CLI.
- Notable — The dual-surface design (browser extension + Swift accessibility bridge) and the record-and-replay capability for live user sessions are technically distinctive; the tool avoids CDP entirely by injecting via standard Web APIs with a
userActivation override and a custom __interceptor_trust event marker.
Verdict

Rating |
Summary |
| Quality |
solid (18/24) |
Actively developed with rich documentation and a lean TypeScript/Swift codebase; penalised only for absent CI signals, an unrecognised license field, and no visible test infrastructure. |
| PAI Relevance |
WATCH (0.38) |
PAI already has an Interceptor skill covering the core browser automation use case; the macOS bridge and record-replay additions are worth monitoring for potential skill updates, but no integration action is required. |

Health: 5/8 (maintained)
Failed:
- H6: FAIL — Open issues = 0; probe requires >0 to indicate active public triage

Documentation: 6/8 (adequately-documented)
Failed:
- D5: FAIL — No heading matching API / Configuration / Options / Reference / Commands / Parameters visible in first 8KB of README; commands appear in code blocks under "Quick Start," not a dedicated reference heading
- D8: FAIL — No Limitations, Caveats, Known Issues, or Trade-offs section; a Warning callout exists but is not filed under one of those headings
Passed:
- D1: PASS — README is present and extensive, covering install, usage, architecture comparison, and quick start
- D2: PASS — README is several thousand words, far exceeding the 1000-byte threshold
- D3: PASS — "Install In 60 Seconds" section details two signed-installer packages, step-by-step install, and post-install verification
- D4: PASS — "Quick Start" section contains bash code blocks for both browser and macOS surface commands
- D6: PASS — Opening line "AI agents use your real browser and macOS apps like a human would." clearly states purpose within the first 500 characters
- D7: PASS — Links to ARCHITECTURE.md and https://hacker-valley-media.github.io/Interceptor/walkthrough.html (external docs site)
Engineering Signals: 7/8 (high-discipline)
Failed:
- E4: FAIL — package.json defines no test script; README contains no mention of tests or testing infrastructure; no CI config visible in the data
Passed:
- E1: PASS — Primary language is Swift (typed); CLI/daemon layer is TypeScript with Bun runtime
- E2: PASS — package.json present with explicit build scripts and strongly-typed dev-dependencies
- E3: PASS — 1 runtime dependency (html-to-image) and 5 dev-dependencies; well under the 15-dep CLI threshold
- E5: PASS — 252 stars exceeds the 50-star adoption threshold
- E6: PASS — Approximately 109 stars/month over a ~2.3-month lifespan (created 2026-03-18), far above the 2/month bar

- E8: PASS — "Agent-driven Chrome extension for full browser control via CLI" is specific and meaningful at >20 characters
PAI Relevance
| Dimension |
Score |
Assessment |
| Harvest Value |
1 |
The Swift macOS accessibility bridge (structured a11y trees, OS-level CGEvent dispatch, TCC-gated trust) and record-and-replay session export are patterns not yet reflected in PAI's existing Interceptor skill; the core browser-control mechanism is already incorporated. |
| Integration Readiness |
2 |
The interceptor CLI is language-agnostic and subprocess-friendly; package.json uses Bun-compatible module syntax; the tool is fully self-hosted, offline-capable, and CLI-first — matching all three of PAI's integration criteria. |
| Overlap Risk |
2 |
PAI's Capability Manifest explicitly lists "Interceptor (stealth Chrome automation)" under Browser & Web skills; this GitHub repo is the upstream source for that skill, making overlap near-complete. |
| Gap Fill |
0 |
No new gap to fill — PAI already has an Interceptor skill; the macOS bridge represents a potential extension of that skill but does not open a new capability category PAI is missing. |
Composite: 0.38
What Next
Automating authenticated web workflows that break under headless browsers: Install the Interceptor Chrome extension and Swift daemon into your existing macOS dev environment, then script the CLI to drive your real logged-in Chrome session for repetitive tasks (pulling reports from admin dashboards, submitting recurring forms, navigating paywalled SaaS UIs). Sessions, cookies, and 2FA state are preserved automatically — no re-auth loop, no bot detection trigger, no separate browser profile to maintain.
Cross-surface macOS automation that spans a web app and a native app: For any workflow that requires reading data from a browser-based tool and writing it into a native macOS application (Calendar, Notes, a local spreadsheet), use Interceptor's dual-surface architecture — browser-side commands via the extension and native UI control via the Swift accessibility bridge — to script the full sequence as a single CLI invocation rather than maintaining two separate automation stacks with a manual handoff between them.
Capturing and replaying multi-step web workflows you already perform manually: Use Interceptor's record-and-replay capability to capture a complex authenticated session (a checkout flow, a multi-page form submission, a dashboard navigation sequence) while performing it once manually in your real browser. The recorded sequence can then be replayed on demand without re-recording, giving you a reusable automation artifact from a workflow you already know works.
Landscape Position
Category: Web & Browser Automation
In this category: unclecode--crawl4ai (solid, integrate) is the only other fully-categorised entry in the vault; ChromeDevTools--chrome-devtools-mcp (excellent, integrate) is filed under MCP Browser DevTools but occupies the same functional space.
Standing: Interceptor is the most agent-native browser tool in the vault — session-preserving, CLI-first, and uniquely extending to native macOS apps — while crawl4ai targets LLM-optimised web scraping and chrome-devtools-mcp targets MCP-protocol agent control; the three are complementary rather than competing peers.
Evidence Base
Density: 9/10 — Available: full README (8KB, highly detailed), dependency manifest (package.json with scripts, deps, and license field), repo metadata (stars, forks, creation date, last commit, release tag, topics, archived status, description). Missing: full source tree, ARCHITECTURE.md contents, .github/workflows/ configuration, test files, and any README content beyond the 8KB cutoff.
Notes
- The Elastic-2.0 license declared in package.json is source-available but not OSI-approved open source; GitHub's SPDX detector fails to recognise it, producing the NOASSERTION field. Consumers should verify licence terms before redistribution or modification.
- The prior rolling-summary entry logged this repo at poor (3.7/24) / note — almost certainly appraised at lower evidence density before the full README and package.json were available. This appraisal supersedes that entry with a solid (18/24) / watch result.
- The Full pkg installer requires macOS 14+ and explicit TCC grants for Accessibility, Screen Recording, and Apple Events; the Swift bridge is significantly more invasive than the Browser-only pkg and warrants careful evaluation in any shared or managed macOS environment.
