SSE error upon setting Roocode Global `mcp_settings.json`

[RyzeNGrind]

Describe the bug

How to run in Roocode(Void Editor)? I am running void editor in remote-wsl (NixOS-WSL) and using Venice.ai API for inferencing. I tried both the docker command and localhost URL but I am getting SSE error: Invalid content type, expected "text/event-stream".

Affected version

Please run docker run -i --rm ghcr.io/github/github-mcp-server ./github-mcp-server --version and paste the output below

❯ docker run -i --rm ghcr.io/github/github-mcp-server ./github-mcp-server --version
GitHub MCP Server
Version: v0.2.1
Commit: 9fa582d8d63522d70ce8f3af58265effb9645323
Build Date: 2025-04-21T23:03:04Z

Steps to reproduce the behavior

1. Type the below mcp_settings.json in global roocode mcp

#Docker command
{
  "mcpServers": {
    "github": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "GITHUB_PERSONAL_ACCESS_TOKEN=${GITHUB_PERSONAL_ACCESS_TOKEN}",
        "-e",
        "GITHUB_DYNAMIC_TOOLSETS=1",
        "ghcr.io/github/github-mcp-server"
      ],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "github_pat_REDACTED"
      },
      "alwaysAllow": [
        "repos",
        "issues",
        "users",
        "pull_requests",
        "code_security",
        "experiments"
      ],
      "autoApprove": [
        "repos",
        "issues",
        "users",
        "pull_requests"
      ]
    }
  }
}

#localhost URL 
{
  "mcpServers": {
    "github": {
      "url": "http://localhost:8080",
      "alwaysAllow": [...],
      "autoApprove": [...]
    }
  }
}

2. View the MCP server output manually instead of via mcp_settings.json

❯ docker run -it --rm -e GITHUB_PERSONAL_ACCESS_TOKEN=github_pat_REDACTED -e GITHUB_DYNAMIC_TOOLSETS=1 ghcr.io/github/github-mcp-server
GitHub MCP Server running on stdio
ping
{"jsonrpc":"2.0","id":null,"error":{"code":-32700,"message":"Parse error"}}

nixos-wsl-micro on  main [!+?⇡] 
❯ echo '{"jsonrpc":"2.0","id":1,"method":"ping"}' | \
  docker run -i --rm \
    -e GITHUB_PERSONAL_ACCESS_TOKEN=github_pat_REDACTED \
    ghcr.io/github/github-mcp-server
GitHub MCP Server running on stdio
{"jsonrpc":"2.0","id":1,"result":{}}

SSE error: Invalid content type, expected "text/event-stream"

Expected vs actual behavior

Expected: Working upon setting mcp_settings.json
Actual: SSE Error

Logs

Running the commands individually seem to work.

Restarting the Void Editor via (Command Pallete)[<Ctrl+Shift+P>] Developer: Reload Window fixed the SSE error.

@RyzeNGrind you included your PAT in the original description. I think you've already revoked it, but just in case you hadn't noticed I thought I'd drop you a comment here.

[RyzeNGrind]

@williammartin thanks Will! I thought I removed all refs but looks like I missed a few, but revoked and regenerated for safety anyways.
