Here is what the current product does, in practical terms: ---- +- **Learns reusable skills from real browsing** + You do the task once in a browser. Schrute turns what it learned into named actions you can run again later. -### 3. Noise filtering — dog.ceo +- **Generates skills in the background** + When you run `schrute stop`, Schrute does not make you wait for all processing to finish in the foreground. It gives you a pipeline job and keeps building the skills in the background. You can check progress with `schrute pipeline `. -**User task:** "List all dog breeds and get a random dog image" +- **Searches and explains what it has already learned** + Once you have multiple skills, Schrute helps you find the right one with `skills search`, inspect it with `skills show`, validate it, export it, and manage it without digging through raw data. -**Site:** dog.ceo (entertainment/fun API) +- **Builds workflows from multiple skills** + If one reusable action is not enough, Schrute can chain several read-only skills together into a larger workflow. That is useful for multi-step tasks like "get account info, then fetch usage, then return a summary." -**Why this workflow matters:** Shows Schrute separating real API calls from page chrome (CSS, images, scripts) on a site that mixes both. +- **Discovers APIs even before you record** + Schrute can scan a site for useful backend clues such as OpenAPI specs, GraphQL endpoints, sitemaps, platform fingerprints, and WebMCP tools. That helps you start faster on sites that already expose a structured backend. -**First run:** -- Path: `schrute explore` → navigate to `/api/breeds/image/random`, `/api/breeds/list/all`, `/api/breed/labrador/images/random` → `schrute stop` -- Pipeline result: 6 requests captured, **3 signal, 3 noise**, **2 skills generated** +- **Reuses the browser session you already trust** + If you are already logged into Chrome or an Electron app, Schrute can attach to that session instead of forcing you through login again. This is especially useful for internal tools and dashboards. -**Learned skills:** -- `dog_ceo.get_all.v1` — `GET /api/breeds/list/all` -- `dog_ceo.get_random.v1` — `GET /api/breed/labrador/images/random` -- Auth used: none (public) -- Safety class: read-only +- **Supports more than one browser session** + You are not limited to one browser context. Schrute can manage multiple named sessions so different sites, accounts, or attached browsers do not all get mixed together. -**Repeated runs:** +- **Handles sites that still need a live browser** + Some sites cannot be cleanly replayed as direct HTTP calls because of Cloudflare, anti-bot checks, or other browser-only behavior. Schrute does not pretend otherwise. It keeps those tasks on a browser-backed path so they still work. -| Run | Skill | Latency | Returned | -|-----|-------|--------:|----------| -| 1 | get_all | 551ms | Full breed list (98 breeds with sub-breeds) | -| 2 | get_random | 558ms | `https://images.dog.ceo/breeds/labrador/Fury_02.jpg` | -| 3 | get_random | 472ms | `https://images.dog.ceo/breeds/labrador/n02099712_1414.jpg` | +- **Lets you call the same learned skills from different places** + The same learned actions can be used from MCP, the CLI, REST, and the Python or TypeScript client packages. That means you do not have to re-teach the task separately for each integration. -**What changed after learning:** The 3 noise requests (page CSS, favicon, scripts) were discarded. Only the 3 JSON API calls became skills. Each execution returns structured JSON in ~500ms instead of loading the full dog.ceo web page. +- **Lets you move and maintain what you learned** + Schrute can export and import learned site bundles, run health checks with `doctor`, show a trust posture report with `trust`, and keep an audit trail of executions. ---- +- **Can improve and maintain learned actions over time** + Schrute can validate skills, track amendments, run optimization on degraded skills, and keep using safer fallback paths when a direct path stops being reliable. -### 4. Cloudflare-protected site — CoinGecko +- **Can work with site-declared tools as well as learned traffic** + On some sites, Schrute can discover useful backend structure such as WebMCP tools, OpenAPI specs, or GraphQL endpoints in addition to what it learns from browser traffic. -**User task:** "Get Bitcoin 24-hour price data" +## Feature Overview -**Site:** www.coingecko.com (finance/crypto) +If you are trying to understand "what is actually included here?", this is the practical feature map: -**Why this workflow matters:** CoinGecko is protected by Cloudflare Turnstile, which blocks headless browsers. When Schrute detects a Cloudflare challenge, it launches a real Chrome browser to attempt clearance, then retries the API call. If the challenge auto-clears (common for Turnstile), execution succeeds automatically. If manual intervention is needed, Schrute returns a 202 with a hint to solve the challenge in the opened browser. +- **Explore and record** + Open a site, perform an action, and let Schrute watch the traffic behind it. -**First run:** -- Path: `schrute explore` → agent navigates CoinGecko, clicks on Bitcoin, views price charts → `schrute stop` -- Pipeline result: **5+ skills generated** from captured API traffic (exact count depends on page traffic) +- **Background processing** + Generate skills after recording without blocking the terminal. -**Learned skills:** -- `www_coingecko_com.get_24_hours_json.v1` — `GET /price_charts/bitcoin/usd/24_hours.json` -- `www_coingecko_com.get_coins.v1` — `GET /price_charts/.../coins` -- `www_coingecko_com.get_csrf_meta_json.v1` — `GET /accounts/csrf_meta.json` -- Plus user info, OTP center, assets endpoints -- Auth used: Cloudflare cookies (browser session) -- Safety class: read-only +- **Skill catalog** + List, search, inspect, validate, export, revoke, delete, and manage learned skills. -**Execution with live-Chrome recovery:** +- **Execution** + Run learned skills directly from CLI, MCP, REST, or client SDKs. -``` -schrute execute www_coingecko_com.get_24_hours_json.v1 --yes -``` +- **Workflow building** + Combine multiple read-only skills into one higher-level reusable flow. -| Step | What happens | Time | -|------|-------------|------| -| 1 | Browser-proxied fetch (Playwright) | Blocked by Cloudflare | -| 2 | Full-browser fetch (Playwright) | Blocked by Cloudflare | -| 3 | Schrute detects Cloudflare challenge page | ~0ms | -| 4 | Launches real Chrome, navigates to CoinGecko | Challenge clears (in tested run) | -| 5 | Retries API call through live Chrome session | **Success** | +- **Discovery** + Scan a site for OpenAPI, GraphQL, sitemaps, platform patterns, WebMCP tools, and other useful backend signals. -- Total latency: **~7,400ms** (includes Chrome launch + challenge clearance) -- Returned: 288 BTC/USD price data points (24h) with timestamps and volumes -- Recovery status: `live_chrome_opened` +- **Browser session reuse** + Attach to a browser you already have open and logged into. -**What this shows:** Schrute handles Cloudflare-protected sites by escalating to real Chrome when headless Playwright is blocked. In the tested run, Turnstile auto-cleared and execution succeeded on the first call. Sites with interactive CAPTCHAs may require manual clearance in the opened browser window. +- **Multi-session support** + Keep separate browser sessions for different sites, accounts, or experiments. ---- +- **Fallback execution** + Keep browser-backed execution for sites that cannot safely or reliably use direct replay. -### 5. Server-rendered site — Hacker News (no skills generated) +- **Import and export** + Move learned site bundles between environments without shipping credentials. -**User task:** "Get the front page of Hacker News" +- **Operational tools** + Use doctor, trust reporting, audit logs, and pipeline status to understand what Schrute is doing. -**Site:** news.ycombinator.com (news/tech) +- **Client access** + Use the same learned actions through MCP, CLI, REST, Python, and TypeScript. -**Why this matters:** Shows what happens when Schrute encounters a site that does not use JSON APIs behind its UI. +## How Schrute Runs A Task -**Result:** -- 12 requests captured -- 0 signal, 10 noise (CSS, images, static assets), 2 document navigations -- **0 skills generated** +Schrute tries to use the simplest reliable path: -**Why:** Hacker News is fully server-rendered HTML. There are no `fetch()` calls to JSON APIs — every page is a full HTML document. Schrute correctly identifies there is nothing to learn and does not generate broken skills. +1. **Browser first** while the task is still being learned +2. **Direct replay later** when the request is stable and safe to reuse +3. **Browser fallback** when the site truly requires a live browser -## Benchmarks +So the goal is not "force everything into direct HTTP." The goal is "use the fastest safe execution mode that actually works." -| Site | Skill | Run 1 | Run 3 | Run 5 | Auth | Noise filtered | -|------|-------|------:|------:|------:|------|---------------:| -| httpbin.org | `get_ip` | 1,029ms | 777ms | 273ms | None | 0/4 | -| dog.ceo | `get_all` | 551ms | — | — | None | 3/6 | -| dog.ceo | `get_random` | 558ms | 472ms | — | None | 3/6 | -| en.wikipedia.org | `get_api_php` | 1,033ms | — | — | None | 0/4 | -| www.coingecko.com | `get_24_hours_json` | ~7,400ms | — | — | CF cookies | — | +That is why sites behind Cloudflare or other anti-bot systems can still be useful in Schrute. If direct replay is blocked, Schrute keeps them on a browser-backed path instead of pretending they should work the same way as a public API. -All runs at Tier 3 (browser-proxied) except CoinGecko which uses live-Chrome recovery. Skills promote to Tier 1 (direct HTTP, ~5-50ms) after 5+ consecutive successful validations. Cloudflare-protected skills remain at Tier 3 with real-Chrome fallback. +## Where It Fits Best -## Where Schrute works best +Schrute is a strong fit when: -Schrute works best when: -- the site uses JSON, GraphQL, or predictable HTTP requests behind the UI -- the task is repeated often enough to justify learning -- the browser session already has the right auth state -- the workflow can be represented as a stable request or request chain +- the site makes predictable HTTP or JSON requests behind the UI +- the task is repeated often +- you already have the right browser auth state +- you want reusable tools instead of one-off browser scripts -Schrute is a worse fit when: -- the site is fully server-rendered HTML with no JSON API calls (like Hacker News) -- the workflow depends heavily on WebSockets, canvas state, or anti-bot challenges on every request -- the task is a one-off and not worth recording -- the action is too risky to replay automatically (destructive mutations without confirmation) +Schrute is a weaker fit when: -## How Schrute differs from other approaches +- the site is mostly server-rendered HTML with no meaningful backend calls to learn +- the workflow depends heavily on canvas, WebSockets, or visual-only interactions +- the task is truly one-time and not worth teaching -### Browser-only agents (Playwright, Puppeteer, Selenium) -Great for first-time discovery, slower and more brittle for repeated workflows. Every repeat pays the full DOM tax. +## Common Use Cases -### Hand-written API integrations -Fast and reliable once built, but require documentation, API keys, auth handling, and custom code per site. +Schrute is especially useful for: -### Schrute -Uses the browser to discover the workflow once, then promotes repeatable actions toward direct HTTP replay. No per-site code. Auth comes from the browser session. Skills self-heal when APIs change. +- **Repeated internal dashboard checks** + Example: pull the same account, usage, or reporting view every day without re-clicking the whole UI. -## Trust and safety +- **Logged-in business tools** + Example: use your existing browser session to access an internal admin panel, support tool, CMS, or analytics product. -Schrute does not blindly replay arbitrary browser traffic. +- **Price, market, and listing lookups** + Example: repeatedly fetch the same market page or structured data endpoint after teaching the browser path once. -Before a learned skill executes, Schrute enforces: -- **Domain allowlists** — only approved domains, SSRF prevention -- **Method restrictions** — GET/HEAD by default, mutations require approval -- **One-time confirmation** — every new skill needs user approval before first execution -- **Path risk heuristics** — destructive-looking paths (`/delete`, `/logout`) are blocked -- **Rate limiting** — 10 QPS default per site -- **Redirect validation** — every redirect hop must pass policy -- **Audit logging** — every execution recorded to SQLite +- **Search and lookup workflows** + Example: teach a site search flow once, then reuse it with different inputs. -Dangerous browser tools (`browser_evaluate`, `browser_run_code`) are blocked entirely. +- **Agent tool creation** + Example: turn a repeated browser task into a reusable MCP tool for an AI coding or operations workflow. -For the full security model, see [SECURITY.md](SECURITY.md). +- **Multi-step read-only automations** + Example: fetch one piece of data, use it in a second call, and return a final combined answer through a workflow skill. -## Auth, cookies, and storage +- **Sites with a mix of easy and hard paths** + Example: let Schrute use direct replay where it works, but keep a live-browser fallback for the parts that truly need it. -Schrute reuses the auth state already present in your browser session. +## Reusing Your Logged-In Browser -- Cookies are stored in the **OS keychain** (macOS Keychain, Linux Secret Service) — not in plaintext files -- Exported skill bundles never include credentials -- Audit logs are stored locally in SQLite -- Auth detection is automatic: Bearer tokens, API keys, OAuth2, session cookies -- JWT TTLs are extracted and used for proactive refresh +If you already have a browser session with the right login state, Schrute can attach to it instead of making you sign in again. -Connect to an existing Chrome session to reuse your logged-in state: +Typical pattern: ```bash -# Launch Chrome with debugging chrome --remote-debugging-port=9222 - -# Connect Schrute -schrute_connect_cdp({ port: 9222, name: "my-chrome" }) ``` -## Self-healing - -APIs change. Auth tokens expire. Schrute handles this automatically. - -A background validation loop runs every 10 minutes: -- Tests skills with last-known-good parameters -- Schema drift detected → re-infer the response schema -- Auth expired → refresh via browser re-login -- Missing parameter → add it from recent traffic -- Still failing → escalate to browser tier (fall back to safety) -- Permanently broken → mark as stale, stop executing - -Every amendment is applied on cooldown, evaluated over a test window, and rolled back if it makes things worse. - -## Cold-start discovery - -Schrute can discover APIs without recording anything: +After that, Schrute can connect to the running browser through CDP using its MCP or REST surfaces. -```bash -schrute discover https://api.example.com -``` +This is especially useful for: -It probes for OpenAPI specs, GraphQL introspection, platform signatures (Shopify, Stripe, WordPress, Firebase, Supabase, Next.js), sitemaps, and WebMCP tools. Discovered endpoints become draft skills ranked by trust level. +- internal dashboards +- admin tools +- sites with multi-step login flows +- flows where the browser already has the right cookies and session state -## REST API and client SDKs +## REST API And SDKs -Start Schrute with HTTP transport for programmatic access from any language: +If you want to call Schrute from scripts or apps: ```bash schrute config set server.authToken my-secret schrute serve --http --port 3000 ``` -```bash -# Execute a learned skill -curl -X POST http://127.0.0.1:3000/api/sites/httpbin.org/skills/get_ip \ - -H "Authorization: Bearer my-secret" \ - -H "Content-Type: application/json" \ - -d '{"params": {}}' +Then call it over HTTP: -# Search for skills -curl -X POST http://127.0.0.1:3000/api/v1/skills/search \ +```bash +curl -X POST http://127.0.0.1:3000/api/v1/execute \ -H "Authorization: Bearer my-secret" \ -H "Content-Type: application/json" \ - -d '{"query": "dog breeds", "limit": 5}' + -d '{"skillId":"httpbin_org.get_ip.v1","params":{}}' ``` -Client SDKs available for **Python** (zero-dependency, `pip install schrute-client`) and **TypeScript** (`npm install @schrute/client`). +Client packages: -Full REST API reference: [docs/rest-api.md](docs/rest-api.md) +- TypeScript: `npm install @schrute/client` +- Python: `pip install schrute-client` -## Docs +MCP HTTP is also available at: -For detailed reference documentation: +```text +http://127.0.0.1:3001/mcp +``` + +## Safety And Storage -- [MCP tools reference](docs/tools.md) — All 40+ MCP tools with parameters -- [CLI reference](docs/cli.md) — Every CLI command and flag -- [REST API](docs/rest-api.md) — 19 HTTP endpoints with examples -- [Security model](SECURITY.md) — Full 9-gate policy engine -- [Architecture](docs/architecture.md) — System design and internals -- [Configuration](docs/configuration.md) — Environment variables, config file, precedence -- [Development](docs/development.md) — Building from source, testing, project structure -- [Client SDKs](docs/sdks.md) — Python and TypeScript usage +Schrute does not blindly replay everything it sees. -
