Running /mcp in Claude Code causes the dialog to render as a blank screen. No servers are listed, and no interaction is possible. The dialog has to be dismissed without being able to view or manage any MCP servers.

Root Cause

Running /mcp in Claude Code causes the dialog to render as a blank screen. No servers are listed, and no interaction is possible. The dialog has to be dismissed without being able to view or manage any MCP servers.

Description

Running /mcp in Claude Code causes the dialog to render as a blank screen. No servers are listed, and no interaction is possible. The dialog has to be dismissed without being able to view or manage any MCP servers.

Environment

  • Claude Code version: 2.1.104 (native)
  • Platform: macOS (Darwin 25.4.0)
  • Shell: zsh

Steps to reproduce

  1. Configure 15+ MCP servers (mix of custom servers, plugins, and cloud integrations)
  2. Run /mcp
  3. Dialog appears blank with no content

Relevant /doctor output

Context Usage Warnings
└ ⚠ Large MCP tools context (~80,827 tokens > 25,000)
  └ MCP servers:
    └ claude_ai_Notion: 16 tools (~15,353 tokens)
    └ customerio: 12 tools (~13,240 tokens)
    └ plugin_sentry_sentry: 16 tools (~11,091 tokens)
    └ linear-server: 42 tools (~9,380 tokens)
    └ claude_ai_Slack: 13 tools (~7,535 tokens)
    └ (15 more servers)

Plugin Errors
└ 1 plugin error(s) detected:
  └ plugin:intercom:intercom [intercom]: MCP server "intercom" skipped — same command/URL as already-configured "intercom"

Expected behavior

The /mcp dialog should render the list of configured MCP servers and allow management (enable/disable/add/remove), even when many servers are configured.

Actual behavior

The dialog is completely blank and non-interactive. The only option is to dismiss it.

extent analysis

TL;DR

The issue can likely be resolved by reducing the number of MCP servers or tools to alleviate the context usage warning.

Guidance

  • Review the /doctor output to identify servers with a large number of tools, such as linear-server with 42 tools, and consider consolidating or removing unnecessary tools.
  • Verify that the issue persists after removing or consolidating tools to determine if the context usage warning is the root cause.
  • Check for any plugin errors, such as the detected error with the intercom plugin, and resolve any conflicts or duplicates.
  • Test with a reduced number of MCP servers (less than 15) to isolate the issue and determine if it's related to the number of servers.

Example

No code snippet is provided as it's not explicitly supported by the issue.

Notes

The issue may be related to the large number of MCP servers and tools, which is causing a context usage warning. Reducing the number of servers or tools may alleviate the issue, but further investigation is needed to determine the root cause.

Recommendation

Apply a workaround by reducing the number of MCP servers or tools to alleviate the context usage warning, as this is the most likely cause of the issue.
