2

Generate Configuration

From the server details page, click Claude Desktop Config
3

Copy Configuration

Click Copy to Clipboard to copy the JSON
4

Open Claude Config File

Navigate to Claude’s configuration file:
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
5

Paste & Save

Paste the configuration and save the file
6

Restart Claude Desktop

Quit and restart Claude Desktop to load the servers

​
Generated Configuration

Studio generates a complete configuration including: 
{
  "mcpServers": {
    "nationalparks-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@nimbletools/mcp-client",
        "https://mcp.nimbletools.dev/{workspace-id}/nationalparks-mcp/mcp"
      ],
      "env": {
        "NTCLI_TOKEN": "your-workspace-token"
      }
    }
  }
}

​
Configuration Components

​
Server Name
string
The MCP server identifier from the registry
​
command
string
Always npx to use the NimbleTools MCP HTTP client
​
args
array
Array containing:
  • -y flag to bypass prompts
  • @nimbletools/mcp-client package
  • Your server’s MCP endpoint URL
​
env.NTCLI_TOKEN
string

​
Multiple Servers

Add multiple MCP servers to Claude Desktop:

​
Option 1: Generate Combined Config

1

Navigate to Workspace Settings

Go to Settings - Claude Desktop
2

Select Servers

Check all servers you want to include
3

Generate Config

Click Generate Combined Config
4

Copy & Apply

Copy and paste into your Claude config file

​
Option 2: Merge Individual Configs

Manually merge configurations from multiple servers: 
{
  "mcpServers": {
    "nationalparks-mcp": {
      "command": "npx",
      "args": ["-y", "@nimbletools/mcp-client", "https://mcp.nimbletools.dev/{workspace}/nationalparks-mcp/mcp"],
      "env": {"NTCLI_TOKEN": "your-token"}
    },
    "finnhub-mcp": {
      "command": "npx",
      "args": ["-y", "@nimbletools/mcp-client", "https://mcp.nimbletools.dev/{workspace}/finnhub-mcp/mcp"],
      "env": {"NTCLI_TOKEN": "your-token"}
    }
  }
}
You can mix NimbleTools servers with locally-run MCP servers in the same config file.

​
Verifying Integration

​
Check Claude Desktop

After restarting Claude Desktop:
1

Open Claude Desktop

Launch the application
2

Look for Tool Indicator

You should see a plug icon or “Tools available” message
3

Start a Conversation

Begin a new chat to test the integration
4

Ask a Question

Try a query that would use your MCP server’s tools

​
Example Queries

“What are the top 5 most visited national parks?”“Show me national parks in California with camping facilities”

​
Tool Call Visibility

Claude will show you when it’s using your MCP tools:

Claude

I’ll search for national parks in California.

Using tool: search_parks

I found 9 national parks in California…

​
Troubleshooting

Possible causes:
  • Claude Desktop wasn’t fully restarted
  • Configuration file has JSON syntax errors
  • Config file is in wrong location
Solution:
  • Fully quit Claude Desktop (check system tray)
  • Validate JSON syntax with a JSON validator
  • Verify file path matches your OS
Possible causes:
  • Server is scaled to zero (cold start delay)
  • Workspace token expired
  • Required secrets not configured
Solution:
  • Wait 5-10 seconds for cold start
  • Refresh token in Studio (Settings - API Tokens)
  • Check server requires secrets and add them
Possible causes:
  • Token expired
  • Token was revoked
  • Wrong workspace token
Solution:
  • Generate a new token in Studio
  • Update NTCLI_TOKEN in config file
  • Restart Claude Desktop
Possible causes:
  • Server scaled to zero
  • First request after idle period
Solution:
  • Set minimum replicas to 1 in server settings
  • Understand cold starts typically take 2-5 seconds

​
Advanced Configuration

​
Custom Environment Variables

Add extra environment variables for specific servers: 
{
  "mcpServers": {
    "your-server": {
      "command": "npx",
      "args": ["-y", "@nimbletools/mcp-client", "https://..."],
      "env": {
        "NTCLI_TOKEN": "your-token",
        "CUSTOM_VAR": "custom-value",
        "DEBUG": "true"
      }
    }
  }
}
Environment variables in Claude’s config are separate from secrets in Studio. These are only used by the client, not the server.

​
Mixing NimbleTools and Local Servers

Run NimbleTools-hosted and local MCP servers together: 
{
  "mcpServers": {
    "nimbletools-server": {
      "command": "npx",
      "args": ["-y", "@nimbletools/mcp-client", "https://mcp.nimbletools.dev/..."],
      "env": {"NTCLI_TOKEN": "your-token"}
    },
    "local-server": {
      "command": "node",
      "args": ["/path/to/local-server/index.js"]
    }
  }
}

​
Configuration Management

​
Backing Up Configuration

Always back up your Claude config before making changes: 
# macOS
cp ~/Library/Application\ Support/Claude/claude_desktop_config.json ~/claude_config_backup.json

# Windows
copy %APPDATA%\Claude\claude_desktop_config.json %USERPROFILE%\claude_config_backup.json

​
Version Control

Store configurations in version control for team sharing: 
# .gitignore - exclude tokens!
claude_desktop_config.json

# Share template without tokens
claude_desktop_config.template.json
