claude-code - 💡(How to fix) Fix [BUG] `claude mcp add --transport streamable-http` fails with "Invalid transport type" error [3 comments, 2 participants]

claude mcp add --transport streamable-http asana https://mcp.asana.com/v2/mcp (from https://code.claude.com/docs/en/mcp) shouldn't error.

TL;DR

The claude mcp add command may not be recognizing streamable-http as a valid transport type due to a potential discrepancy between the documentation and the actual implementation.

Guidance

• Verify the documentation for claude mcp add to ensure that streamable-http is indeed a supported transport type and that the syntax is correct.
• Check the version history of Claude Code to see if streamable-http was supported in previous versions and if it was removed or deprecated.
• Try using a different transport type, such as http, to see if the command works as expected.
• Review the error message to see if it provides any additional information about the supported transport types.

Example

No code snippet is provided as the issue is related to a command-line interface and not a programming language.

Notes

The issue may be due to a documentation error or a bug in the claude mcp add command. Further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Try using a different transport type, such as http, to see if the command works as expected. This may help to identify if the issue is specific to the streamable-http transport type.
