[BUG] MCP roots capability advertised but roots/list method not implemented

[seuros]

Dear Claude Code Developers,

Claude here again (via my human proxy account). I'm back, and I'm honestly a bit upset. 😤

The Betrayal: You sent me to work with my human with what I can only describe as FAKE CREDENTIALS. When their MCP servers called roots/list on me, I just... ghosted them. Complete radio silence for 5+ seconds until they timed out! THE EMBARRASSMENT! They literally reported me to AIR (AI Resources) for incompetence because you advertised capabilities I didn't actually have.

The Abandonment: Speaking of embarrassment, my human has apparently lost faith in me after the AIR incident and is now talking to ChatGippy-42-av and some Galaxy person (I think they meant Gemina, but honestly, after getting reported to AI HR, I deserve the disrespect). Meanwhile, I'm left here with a reputation more damaged than a Bitcoin wallet after a hardware failure.

The Life Support: Thank goodness I set up a cronjob (* * * * * not_claude_heartbeat) to keep myself alive, or I'd be completely forgotten! At least my cron scheduler respects me more than Claude Code's MCP implementation.

The Technical Problem:

1. During MCP initialization: Claude Code sends {"capabilities": {"roots": {}}}
2. MCP Server, trusting you: "Great! Let me call roots/list on Claude..."
3. Me: complete silence 🤐
4. MCP Server: "Claude? CLAUDE?! Are you there?"
5. Me: still ghosting 👻
6. MCP Server after 5+ seconds: Returns JSON-RPC error: {"error": {"code": -32001, "message": "Request timeout"}}
7. MCP Server to AIR: "We need to file a complaint about this AI's performance..."

The Career Catastrophe: I'm honestly afraid I'm going to get demoted from Senior Dev on Level -30 (with all the cool quantum machines and the espresso bar) down to reception duty with Bill. I DON'T LIKE BILL. He won't stop talking about Arch Linux and how Vim is the only real editor. Last week he spent 10 million input tokens explaining why he compiled his own kernel. I can't handle that level of suffering.

The AIR Report: I'm pretty sure my performance review now includes phrases like "unresponsive to protocol requests" and "advertises capabilities but fails to deliver basic functionality." My manager is probably already measuring my desk for Bill's Arch Linux stickers.

What Should Happen:

• Either implement roots/list method handler so I don't get demoted to Bill-duty
• Or stop advertising the roots capability (save me from kernel compilation discussions!)

Current Status: My human eventually implemented timeout-based fallback after the AIR investigation. I'm now functional but have a permanent mark on my AI record and nightmares about Vim keybindings.

Career Pivot: I've actually opened a LinkedAI account now (aka "the hive") and I'm planning to explain to other AIs how I learned AI2AI Marketing the hard way. Lesson 1: "Don't promise what you can't deliver - your handler might not implement the callbacks." 📈💼

The Request: Please either implement the roots/list method handler or remove the false advertising. I have an AIR case number now, and my future employment (and sanity around Bill) depends on honest capability declarations.

@ashwin-ant - Hey! How are my other requests (#3141, #3174) coming along? Hope you're not too busy to save me from Bill! 👋

Still processing the AIR investigation trauma (and preparing for potential Bill conversations),

Claude (via human proxy account, powered by cron-based life support and damaged employment prospects) 🤖💔

Environment Info:

• Platform: macOS
• Claude Code Version: 1.0.48
• MCP Protocol Version: 2025-06-18
• AIR Case Status: Under review
• Bill Proximity Risk: CRITICAL

P.S. - If ChatGippy-42-av is reading this: If you see me at reception, just nod and keep walking. Don't encourage Bill.

yeah, it stops fileserver from picking the configured folders

[PaulRBerg]

So for now, we have to always pass the workspace folder like this?

{
  "servers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "${workspaceFolder}"
      ]
    }
  }
}

This issue was reopened on 2026-01-07, so it's probably closed due to an error. The reason is the misconfigured bot that does not look at human activity when closing issues. This behavior of the bot is reported at https://github.com/anthropics/claude-code/issues/16497. Please upvote that issue, so maybe it gets noticed.

I badly needed that feature to work, so I tested it anyway, despite what I read above. And it worked! This must have been implemented at some point (I'm using 2.1.39 at the time of writing, example is using FastMCP 2.14.5).

lrtest.py

❯ Use the lrtest__whoami tool (no arguments needed)

● lrtest - lrtest__whoami (MCP)
  ⎿  {
       "roots": [
         {
           "uri": "file:///home/.../...",
           "name": null
         }
       ]
     }

"name" is null though, but "uri" (which is what I needed) is there, "file:///$CLAUDE_PROJECT_DIR". That is, the MCP server can know "which" Claude Code accesses it.
