    apify website-content-crawler fails: proxyConfiguration required even when not sent

    With apify-mcp-server, the apify-slash-website-content-crawler tool fails with AI_InvalidToolArgumentsError saying proxyConfiguration is required even though the call doesn't include it. Both WCC and a mastra.ai agent hit this error. Is this a known server bug and was it fixed?

      Status: fixed. A contributor stated the problem was "fixed (hacked together)" in https://github.com/apify/actors-mcp-server/pull/45 (opens external site), and the issue was closed as COMPLETED. The thread does not name a release version or describe what changed inside the PR.

      The failure is a tool-argument validation error from apify-slash-website-content-crawler. A call such as:

      json
      {"startUrls":[{"url":"https://shveik.dev"}],"crawlerType":"playwright:adaptive","maxCrawlPages":5}

      failed with:

      AI_InvalidToolArgumentsError: Invalid arguments for tool apify-slash-website-content-crawler: Type validation failed ...
{"code":"invalid_type","expected":"object","received":"undefined","path":["proxyConfiguration"],"message":"Required"}

      The original report was a bad WCC run, and a contributor also saw the same failure from a mastra.ai agent with the WCC proxy configuration. The thread does not mention a client-side configuration change that fixes the error. General advice: use a build of the MCP server that includes PR #45; since no release version was named, check the package's release notes or changelog if you install a released binary.

      What a GitHub user tried on GitHub (Outcome unclear)

      The issue reporter ran the tool with WCC and reported a bad run, linking to an Apify run log. The thread does not describe what the log showed.

      What @MQ37 tried on GitHub (Didn't work)

      A contributor reported that a mastra.ai agent failed with the WCC proxy configuration and included the exact AI_InvalidToolArgumentsError output. This reproduced the same validation failure but no workaround was proposed in that comment.
