How to Set Up Serena MCP with Qoder on Windows

How to Set Up Serena MCP with Qoder on Windows

1. Prerequisites

• Windows 10/11
• Qoder is installed
• uv is installed via WinGet or another method (uvx.exe is available)
• Git for Windows is installed, and git --version can be run in PowerShell

2. Problem Overview

While Serena MCP runs correctly in a WSL environment, the following issues occur on native Windows:

• When launched with a stdio connection, Qoder does not communicate with Serena after startup.
• With a streamable-http connection, Qoder accesses the root (/) and receives a 404 error.

This results in a state where "Qoder cannot connect to Serena."

3. Verified Solution

3.1 Manually Start Serena as an HTTP Server

First, run the following command in PowerShell to start Serena MCP in streamable-http mode.

uvx --from git+https://github.com/oraios/serena serena start-mcp-server --context ide-assistant --transport streamable-http

• By default, the server starts at http://127.0.0.1:8000.
• A "StreamableHTTP session manager started" message in the log indicates a successful launch.

3.2 Configure mcp.json in Qoder

Configure Qoder to use Serena MCP via an HTTP connection.
The key is to set the URL to /mcp, as the root (/) will result in a 404 error.

"serena": {
  "type": "streamableHttp",
  "url": "http://127.0.0.1:8000/mcp"
}

After this, enabling "MCP" in Qoder will establish the connection from Qoder to Serena.

4. Important Notes

• This requires the manual step of starting Serena.
• If you want Serena to run persistently, you can use the Windows Task Scheduler to launch it automatically on logon.

5. Summary

1. Start Serena MCP with --transport streamable-http in PowerShell.
2. Set the url in Qoder's mcp.json to http://127.0.0.1:8000/mcp.
3. Optionally, use Task Scheduler to automate the launch.
