feat(tools): add native MrScraper integration - #7231
Conversation
📝 WalkthroughWalkthroughThe PR adds a native MrScraper integration with 15 typed CrewAI tools, shared authenticated API handling, toolkit selection, generated tool specifications, contract tests, opt-in smoke tests, and localized documentation. ChangesMrScraper integration
Merge Risk: 🟡 Moderate · up to A redirect from the API can expose users' MrScraper tokens to another host. Valid toolkit and rendered-page invocations can also fail, and returned HTML can be altered.

Requests 2.33.0 Session.request redirect handling custom headers x-api-token off-host redirects official documentation
💡 Result:
In the Python requests library (including version 2.33.0 and later), the behavior regarding custom headers during redirects is as follows: 1. Authorization Header Stripping: The requests library intentionally removes the Authorization header if a request is redirected to a different host (or changes the scheme/port, such as https to http) [1][2][3]. This is a security measure designed to prevent the leakage of sensitive credentials to unintended endpoints [3][4]. The library identifies whether to strip this header using the should_strip_auth method in the Session object [1][2][5]. 2. Custom Header Persistence: Unlike the Authorization header, standard custom headers (such as x-api-token) are generally preserved across redirects because requests does not apply special security logic to arbitrary user-defined headers [6][3]. Requests simply passes these headers forward into the subsequent redirected request [6]. 3. Recommendations for Handling Sensitive Tokens: If you require an authentication token to be sent during a cross-host redirect, the recommended approaches are: - Avoid Redirection: Configure your application or the target API to avoid redirects by hitting the final endpoint directly [3]. - Disable Automatic Redirection: Set allow_redirects=False in your request, handle the redirect response manually, and re-issue the request with the headers included [6][7]. - Custom Authentication Class: Implement a custom authentication handler by subclassing requests.auth.AuthBase [8]. When passed via the auth parameter, your class can ensure the header is applied to the request regardless of whether it is an initial request or a follow-up to a redirect [8]. Note that since Requests' internal redirect logic specifically targets the Authorization header, using a custom auth class can be an effective way to manage token injection [8]. Documentation reference: While the official Quickstart guide specifically warns that Authorization headers will be removed if you are redirected off-host [6], it confirms that custom headers passed via the headers parameter are otherwise maintained as part of the request session or individual request configuration [6][9].

Sensitive Data Exposure (CWE-200): Exposure of Sensitive Information to an Unauthorized Actor
Disable automatic redirects for authenticated requests.
Requests preserves the custom x-api-token header across cross-origin redirects. A redirect to an untrusted origin can disclose the token. Pass allow_redirects=False, or validate each redirect before rebuilding authentication headers.

Redact only the configured token.
_TOKEN_QUERY_RE replaces every token query value. A SERP HTML response that contains a normal link such as ?token=public-value is changed, although MrScraperSearchGoogleSerpTool promises exact HTML output. Restrict query-value redaction to self._token, including its URL-encoded form.

Document the model credential for the Agent example.
The documented setup exports only MRSCRAPER_API_TOKEN, but the equivalent smoke path requires OPENAI_API_KEY before constructing Agent and calling Crew.kickoff(). Add conditional OPENAI_API_KEY setup or pass an explicit configured LLM.

Normalize scalar selector arguments.
str satisfies Iterable[str]. create_mrscraper_toolkit(groups="discovery") iterates individual characters and raises an unknown-group error instead of selecting discovery. The same failure occurs for a scalar tool_names value. Treat strings as one selector before iteration, or reject them explicitly.

MrScraper API waitUntil networkidle domcontentloaded load networkidle0 networkidle2
💡 Result:
The MrScraper API uses the waitUntil parameter to define when the browser considers a navigation complete, with options identical to those found in Puppeteer [1][2][3]. The available values are: domcontentloaded: Navigation is considered successful when the DOMContentLoaded event is fired (the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes) [4][5]. This is the fastest option but may not include dynamically rendered content [6]. load: Navigation is considered successful when the load event is fired (the entire page, including all dependent resources like images and stylesheets, has fully loaded) [4][5]. networkidle0: Navigation is considered successful when there are no more than 0 network connections for at least 500 milliseconds [4][5]. This is the most thorough option, ensuring all background network activity has ceased, but it is also the slowest and may timeout on pages with continuous background requests (e.g., analytics or chat widgets) [1][3]. networkidle2: Navigation is considered successful when there are no more than 2 network connections for at least 500 milliseconds [4][5]. This is often the most practical choice, as it accounts for minor background noise while still waiting for the primary content to load [4][7]. Best Practices for MrScraper MrScraper documentation explicitly recommends using domcontentloaded in combination with waitForSelector for most scraping tasks [6]. This approach is generally faster and more reliable than networkidle because it waits for the specific content you need to appear in the DOM rather than waiting for unrelated background network traffic to settle, which can be unpredictable or indefinitely long [6][8].

Summary
This PR adds a native MrScraper integration to crewai-tools, exposing 15 independent tools for account access, URL discovery, Google SERP search, extraction, scraper creation, result retrieval, and existing scraper execution.
The integration uses shared secret-safe authentication and HTTP handling, strict Pydantic input schemas, conditional validation for AI and manual scraper options, toolkit filtering, generated discovery specifications, localized documentation, unit tests, and opt-in real-service smoke tests.
Review follow-up from #7161 removes the account-specific scraper ID, keeps smoke-test configuration environment-only, aligns real-estate prompts with their schemas and targets, resolves fixture paths relative to the test module, regenerates discovery schemas from runtime models, and adds schema-parity regression coverage.

Additional context
Real API smoke tests require MRSCRAPER_API_TOKEN. Result and rerun tests additionally read MRSCRAPER_AI_SCRAPER_ID, MRSCRAPER_MANUAL_SCRAPER_ID, or MRSCRAPER_RESULT_ID as applicable. The CrewAI Agent smoke test also requires OPENAI_API_KEY.
