Disable specific tools from your MCP servers

Sometimes you don’t want every tool exposed to your AI assistant — maybe a tool is noisy, experimental, or not relevant to a workflow. MCP Nest lets you disable tools per‑user right from the Dashboard.

Disabling a tool is also a great way to preserve context and reduce tokens!

How to disable a tool

1. Open the Dashboard after your servers have been discovered
2. Find the tool inside its server card
3. Click the toggle — disabled tools appear muted and won’t be used
4. Click “Refresh” if you’ve just changed or redeployed your servers and want to re‑scan tools

Your client will no longer see disabled tools in tools/list, so it won’t attempt to call them.

What changes (and what doesn’t)

• Your setting is personal: each user manages their own toggles
• Only disabled tools are stored; everything else stays enabled by default
• Disabling a tool does not stop your servers — it simply hides that tool from the assistant

Reading the Dashboard

• Total Tools Discovered: All tools reported by your running servers
• Enabled Tools: Count after your personal disables are applied
• Per‑server cards: Each card groups tools by server with a badge showing the count

Tips

• Keep your list focused by disabling rarely‑used or risky tools
• If the list looks stale, click “Refresh” to re‑discover tools from your servers
• Tool names come from the upstream server; renamed tools will appear with their new name after a refresh
