`http` protocol mcp server failing

[redoxahmii]

What happened?

I am using Figma MCP server and this is the settings.json I have.

  "mcpServers": {
    "Figma": {
      "httpUrl": "https://mcp.figma.com/mcp"
    },}

When running qwen it prompts me with Command command not found during MCP server initialization.

This could be an issue of how it is different for setting these servers in qwen to gemini because it is identical and it works in gemini.

What did you expect to happen?

Connect with the MCP server

Run qwen to enter the interactive CLI, then run the /about command.

Login information

Oauth

Anything else we need to know?

No response

And I can't log into MCP Figma

And I can't log into MCP Figma

Same here I've had to manually copy over the auth when authenticated with gemini and it's saved there.
Try that, the file name should be mcp-oauth-tokens.json

I see that HTTP MCP servers use StreamableHTTPClientTransport (in packages/core/src/tools/mcp-client.ts).

The "Command command not found" error is weird for an HTTP URL.

Could you try using the qwen mcp add command instead of manually editing settings.json?

Something like: qwen mcp add --transport http Figma https://mcp.figma.com/mcp

That might set up the config correctly with all required fields.

I figured out the problem. Gemini in Figma changed the client name from "Gemini CLI (Google ADC)" to "Gemini CLI MCP Client". Qwen still uses the old name, which is why Figma is not accepting it. To fix this, you need to find the file cli.js in the @qwen-code package and replace client_name: "Gemini CLI (Google ADC)" with client_name: "Gemini CLI MCP Client".

Ok, I am able to reproduce the issue on the "main" branch on my Macbook (run "npm run start", issue "/mcp auth Figma" and then press ctrl-o):

{
    "security": {
        "auth": {
            "selectedType": "qwen-oauth"
        }
    },
    "mcpServers": {
        "Figma": {
            "httpUrl": "https://mcp.figma.com/mcp",
            "oauth": {
                "enabled": true
            }
        }
    },
    "$version": 2
} 

Please wait for my PR

It looks better now (on the git branch of my PR), I am redirected to Figma OAuth and successfully authenticate, but I want to investigate the warnings printed in the ctrl+o console:

[afarber]

All right, I have verified that the initial warnings are expected. Then the Figma auth token is cached in ~/.qwen/mcp-oauth-tokens.json and they will not appear on subsequent starts. My fix #1302 is complete, please review @xuewenjie123

Here on subsequent start and with "/mcp" prompt issued:
