What happened?

The Developer knowledge API does not support prompts.

When Gemini CLI starts - it throws a warning about this support but does not list the tools:

🟢 DeveloperKnowledge (from DeveloperKnowledge) - Ready Error: Error discovering prompts from DeveloperKnowledge: MCP error -32601: Method not supported

What did you expect to happen?

The tools that are supported should be listed

TL;DR

The Developer Knowledge API's lack of support for prompts is likely causing the error, and a workaround or update may be necessary to resolve the issue.

Guidance

  • Verify the error message "MCP error -32601: Method not supported" is related to the Developer Knowledge API's prompt support.
  • Check the Gemini CLI documentation to see if there are any known issues or workarounds for this error.
  • Investigate if there are any updates or patches available for the Developer Knowledge API or Gemini CLI that may address this issue.
  • Consider reaching out to the API or CLI support team for further assistance, as the error message suggests a limitation in the API itself.

Notes

The issue seems to be related to a limitation in the Developer Knowledge API, and without more information about the API or CLI versions, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: The error message suggests a fundamental limitation in the API, so applying a workaround or waiting for an update that adds prompt support may be the best course of action.
