Claude Code Discord MCP Plugin - Fixing asdf bun Path Issue

Thu, 26 Mar 2026 00:00:00 +0900

Problem

When installing the discord plugin for Discord channel integration in Claude Code CLI, I encountered the following error:

> discord Plugin · claude-plugins-official · √ enabled
 └ discord MCP · × failed

The plugin was enabled, but the MCP server was in a failed state.

Root Cause

This issue occurs when using bun installed via asdf. Claude Code CLI looks for the bun command to run the MCP server, but asdf uses shell wrappers, so the actual binary cannot be found in the system-wide path.

Solution

I resolved this by entering the absolute path to the bun installed via asdf.

Finding the Absolute Path of asdf-installed bun

which bun

Or:

asdf where bun

Example output:

/Users/yarang/.asdf/installs/bun/1.x.x/bin/bun

Applying the Configuration

Specify this absolute path as the execution path in the Discord MCP configuration, and the problem will be resolved.

Summary

Situation	Solution
System-wide installed bun	Use `bun` command
asdf-installed bun	Enter absolute path directly

When using asdf, you must specify the actual binary path, not the shell wrapper, for the MCP server to run properly.
