Adds a news search tool backed by Webz.io's hosted News Search MCP server, so agents can search global news articles and blog posts and get back title, url, publication date, source, language and text. The tool fetches its argument schema from the MCP server on construction, which keeps the ~26 server-side filters (language, country, published date, sentiment, domain, ...) available to agents without a crewai-tools release whenever Webz.io adds one. Construction falls back to a query-only schema and retries on the first search when the server is unreachable or the token is missing, so building the tool stays safe at import time and under pytest's --block-network.

Replaces the staging bundle with the files as actually submitted in crewAIInc/crewAI#7309, including the docs/edge/ path, the ar/ko/pt-BR translations required by DOCS_TRANSLATIONS.md, and a patch of the edits to files that already existed upstream. Notes where the upstream tool deliberately diverges from the standalone crewai-webzio package.

- Line 60: Make MCP session cleanup exception-safe in the localized
WebzioNewsSearchTool examples by wrapping setup and crew.kickoff() in the
WebzioNewsSearchTool context manager, or by placing them in a try/finally that
always calls news_tool.stop(). Apply the same change to each localized example
and preserve normal kickoff behavior.
In
`@lib/crewai-tools/src/crewai_tools/tools/webzio_tools/webzio_news_search_tool.py`:
- Line 135: Validate the normalized URL in the Webzio news search tool before
constructing MCPServerAdapter, requiring an absolute https:// endpoint and
rejecting cleartext or non-absolute URLs before the Authorization token is sent.
Preserve the existing trailing-slash normalization in the mcp_url handling.
- Line 125: Serialize the MCP lifecycle in WebzioNewsSearchTool by guarding
_connect() and stop() with one re-entrant lock. Build setup through a local
MCPServerAdapter, assign shared state only after successful initialization, and
close the local adapter if setup fails; hold the same lock across _run()
delegation when stop() must not close an active session.

Serialize _connect() and stop() with a threading.Lock, build through a local MCPServerAdapter, and close it on handshake failure so concurrent searches cannot leak duplicate MCP sessions. Reject non-HTTPS MCP endpoints before sending the Bearer token. Update the docs examples in all four locales to use the context manager for exception-safe cleanup, add docstrings to the tests, and cover the new behavior with concurrency and cleartext-endpoint tests.

Updates the submitted tool, tests, and four-locale docs to match crewAIInc/crewAI#7309 commit 0cdbbe4, including the MCP lifecycle lock, strict HTTPS validation, and context-manager doc examples.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert that each search thread completed.
thread.join(timeout=2) returns when the timeout expires. This test can pass with one adapter call and no captured exception while a worker remains blocked. Assert that every thread is no longer alive after joining.
Proposed fix
for thread in threads:
thread.join(timeout=2)
+ assert not thread.is_alive()📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary
crewai-toolshas broad web search coverage but no tool dedicated to news search, so agents doing media monitoring or event tracking have to filter general web results down to news themselves and lose the metadata that makes news usable. This addsWebzioNewsSearchTool, which searches Webz.io's news index and returns title, url, publication date, source, language and text for each result.The tool is built on the hosted Webz.io News Search MCP server via the existing
crewai_tools.adapters.MCPServerAdapter— the first tool in the catalog to use it, rather than asking users to wire up an MCP server themselves. The reason to go through MCP rather than hand-writing a Pydantic schema is that the tool fetches its argument schema from the server on construction, so the ~26 server-side filters (language, country, published date range, sentiment, domain rank, category, entity filters) stay available to agents without acrewai-toolsrelease each time Webz.io adds one. Verified live against the production server: 26 filter fields are adopted and searches return results.Two design points worth calling out for review:
MCPServerAdapter.__init__connects eagerly and raisesRuntimeErroron failure, which would makeWebzioNewsSearchTool()unusable at import time and under this repo's--block-networkpytest setting. So the tool catches that, keeps aquery-only fallback schema (extra="allow", since the server validates filters anyway), and retries the connection on the first search — which is where a missing token or an unreachable server is reported. There are tests for both the offline-construction and the retry-on-first-call paths.tool.specs.jsonrecords the fallback schema, not the live one.ToolSpecExtractorreads class-level schemas, sorun_params_schemashowsqueryonly. That is the trade for not hardcoding the filter list;env_vars,init_params_schemaandhumanized_nameare all complete.The MCP session is kept open and reused across searches, and is closed by
stop()or by using the tool as a context manager.Verification
The 15 new tests mock
MCPServerAdapter, so they make no network calls and are safe under--block-network. They cover the token and URL resolution from both arguments and env vars, adopting the live schema, delegation to the MCP tool, connection reuse across searches, construction with an unreachable server, construction with a missing token, the error surfaced on first search, retrying a deferred connection, a server that doesn't expose the tool,stop()and its idempotency, the context manager, the fallback schema accepting server-side filters, and the entry intool.specs.json.I also ran a live check against the production MCP server with a real token: 26 filter fields adopted, results returned, clean shutdown.
