[MCP] Javascript Heap Out of Memory

[shen-david]

Summary

When using claude code and firebase-tools@14.23.0 (because of #9443), I get the following oom crash. My workaround right now is to add

"env": {
        "NODE_OPTIONS": "--max-old-space-size=8192"
      }

to the .mcp.json.

Here's my full .mcp.json

{
  "mcpServers": {
    "firebase": {
      "command": "npx",
      "args": [
        "-y",
        "firebase-tools@14.23.0",
        "mcp",
        "--only",
        "crashlytics"
      ],
      "env": {
        "NODE_OPTIONS": "--max-old-space-size=8192"
      }
    }
  }
}
