Railway MCP Error

Questions
1

Hey Everyone,

I’m getting the following error after installing the n8n mcp community node.

The mcp nodes work for a bit, then the connection closes and give me the following error: Failed to execute operation: Failed to connect to MCP server: MCP error -32000: Connection closed

I’m self hosting using Railway.

Does anyone have a solution for getting this to work consistently?

this helped me fix the issue for gitlab, maybe help you fix for this

const nodeExecutablePath = process.execPath; // Path to the currently running node
const nodeDir = path.dirname(nodeExecutablePath);
const currentPath = process.env.PATH || ‘’;
// Prepend node’s directory to PATH (safer than replacing)
const effectivePath = ${nodeDir}${path.delimiter}${currentPath};

const childEnv = {
    ...process.env, // Inherit parent environment
    ...(serverConfig.env || {}), // Add environment vars from config
    PATH: effectivePath, // Override PATH to include node dir
}
const params: StdioServerParameters = {
    command: serverConfig.command, // Should still be the absolute path to npx here
    args: serverConfig.args,
    // --- Use the constructed environment ---
    env: childEnv,
    // cwd: serverConfig.cwd || undefined // Optional: Set working directory
};

      const transport = new StdioClientTransport(params);
      const client = new McpClient({ name: `mcp-gemini-backend-${serverKey}`, version: "1.0.0" });
