Duplicate MCP Servers In Cursor Settings

Support Bug Reports
1

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In Cursor Settings → Tools & MCP → Installed MCP Servers, I’m seeing duplicate entries for the same MCP server(s). I checked the MCP server config file and it does not contain duplicates, so this seems like a UI list duplication or caching/state issue.

Steps to Reproduce

1.	Open Cursor
2.	Go to File -> Cursor Settings
3.	Navigate to Tools & MCP
4.	Open Installed MCP Servers
5.	Observe duplicate MCP server entries

Expected Behavior

Each installed MCP server should appear exactly once in the Installed MCP Servers list, matching the config file.

Additional Information

Asked AI and it gave back some clues maybe a nested read from the project…

There are two likely reasons Cursor says you have duplicate MCP:
1. Project + global config (most likely)
Cursor loads MCP from both:
Project: .cursor/mcp.json (this repo)
Global: ~/.cursor/mcp.json (macOS)
If the same server name (e.g. playwright, memory, figma) exists in both files, Cursor merges them and reports duplicates. Fix: Remove or rename the duplicate entries in one of the two files (usually keep project-specific ones in .cursor/mcp.json and shared ones only in ~/.cursor/mcp.json).
2. Two server sections in this file
Your project config has two top-level keys that both define servers:
mcpServers – playwright, chrome-devtools, memory, context7, etc.
servers – figma (HTTP)
Cursor’s expected format is a single mcpServers object. Having a separate servers key can confuse the UI or merging logic and look like duplicates. Fix: Put all servers under mcpServers. HTTP servers like Figma belong there with a different shape (e.g. url + transport type).
I can:
Merge servers into mcpServers in .cursor/mcp.json so Figma is under mcpServers in the format Cursor expects, and remove the servers key, or
Inspect your global config – if you paste (or describe) the contents of ~/.cursor/mcp.json, I can point out which names are duplicated and how to fix them.
Say which you want (or both), and I’ll do it.

if this is the case could we add an option to be project scoped vs. wider or globally scoped MCP?

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. Your AI assistant was almost completely right. Cursor merges MCP configs from two places:

  • Project: .cursor/mcp.json
  • Global: ~/.cursor/mcp.json

If the same server is defined in both files, it will show up twice in the UI. That seems like what’s happening here.

Also worth checking: you mentioned the config has both mcpServers and servers. Cursor expects everything under mcpServers. Having a separate servers key can confuse the UI. Move Figma (and any other entries) into mcpServers and remove the servers key entirely.

Quick fix:

  1. Decide which servers are project-level vs global, and keep each one in only one file
  2. Put everything under mcpServers and delete the servers key

If you still see duplicates after that, share the contents of ~/.cursor/mcp.json and .cursor/mcp.json and I’ll take a closer look.

On your request for a clear MCP scope split (project vs global), the team is aware. No timeline yet, but your feedback helps with prioritization.

Description:

I am reporting a UI duplication bug in the “Tools & MCP” settings. My AI Agent has performed a deep inspection of my local environment and identified the root cause in the internal state database.

Analysis by AI Agent:

The agent inspected the SQLite database at %APPDATA%\Cursor\User\globalStorage\state.vscdb and found that the key mcpService.knownServerIds contains duplicated entries for every server, using two different namespaces:

  1. user-[server-name] (Global scope)

  2. project-0-narci-[server-name] (Project scope)

The issue occurs because:

My workspace root is set to my HOME directory (C:\Users\narci). Since the global mcp.json resides in C:\Users\narci\.cursor\mcp.json, Cursor’s indexing logic is incorrectly loading it twice: once as the global config and once as a project-specific config (because it’s technically inside the open workspace).

Environment:

  • OS: Windows 10

  • Cursor Version: [Inserta tu versión desde Help → About]

  • Config: Single mcp.json file at %USERPROFILE%\.cursor\mcp.json

Steps to Reproduce:

  1. Set the global MCP config in %USERPROFILE%\.cursor\mcp.json.

  2. Open the %USERPROFILE% folder as the active workspace in Cursor.

  3. Go to “Cursor Settings” → “Tools & MCP”.

  4. Observe every MCP server listed twice (one for each internal namespace).

Expected Behavior:

Cursor should detect that the project mcp.json is the same as the global one and avoid duplicating the servers in the UI and internal state.
