Third-party Tools using CrewAI not working

[a-ml]

Hello,

Since upgrading to the last google-adk version I'm no longer able to use the SerperTool from crewai-tool. Does anyone knows if it's not working in this version?

Using Tool: Search the internet with Serper
2025-08-01 19:20:35,070 - 8710561536 - serper_dev_tool.py-serper_dev_tool:182 - ERROR: Error making request to Serper API: 400 Client Error: Bad Request for url: https://google.serper.dev/news

The only change in my codebase was, to update the google-adk version.

@a-ml Were you able to resolve this?

@a-ml The #3036 sahilsuneja1 linked was exactly this. FunctionTool's parameter filtering was stripping real args (like search_query) from CrewAI-style **kwargs tools causing that "Missing query parameter" error. It was fixed and merged back in October so should be resolved on current ADK versions. Could you upgrade and confirm SerperDevTool works again on your end? Closing this out for now, feel free to reopen if you're still hitting it.
