Troubleshooting

Installation Issues

Command not found: ntcli

NPM Installation Issues

Symptoms: ntcli: command not found after running npm install -g @nimbletools/ntcliCause: NPM global bin directory not in PATHSolutions:

Check NPM global bin location:

npm config get prefix 
# Should be in your PATH

Add NPM global bin to PATH:

# Add to ~/.bashrc, ~/.zshrc, etc. 
export PATH=$(npm config get prefix)/bin:$PATH

Verify installation:

which ntcli ntcli
--version

Permission Errors

Symptoms: EACCES permission denied errors during installationCause: NPM trying to write to system directoriesSolutions:

Configure NPM to use user directory (recommended):

mkdir ~/.npm-global 
npm config set prefix '~/.npm-global' 
echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc 
source ~/.bashrc npm install -g @nimbletools/ntcli

Use Node Version Manager (recommended):

# Install nvm curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash 
# Install and use Node.js 
nvm install node 
nvm use node 
npm install -g @nimbletools/ntcli

Old Version After Update

Symptoms: ntcli --version shows old version after updateCause: Multiple installations or cached binaries Solutions:

Clear NPM cache:

npm cache clean --force

Complete reinstall:

npm uninstall -g @nimbletools/ntcli
npm install -g @nimbletools/ntcli

Check installation location:

which ntcli ls -la $(which ntcli)

Authentication Issues

Browser Doesn't Open

Symptoms: Browser doesn’t automatically open during ntcli auth loginSolutions:

Manual browser opening:

ntcli auth login --verbose
# Copy the URL from the output and open manually

Check default browser:

# macOS
defaults read com.apple.LaunchServices/com.apple.launchservices.secure LSHandlers

# Linux - check $BROWSER variable
echo $BROWSER

Use alternative browser:

# Set browser temporarily
export BROWSER=firefox
ntcli auth login

Port Already in Use

Symptoms: Error: listen EADDRINUSE: address already in use :::41247Solutions:

Use different port:
```
ntcli auth login --port 8080
```

Find process using port:

# Find process using port 41247
lsof -i :41247

# Kill process if safe to do so
kill -9 <PID>

Set default port:

export NTCLI_DEFAULT_PORT=8080
ntcli auth login

Timeout During Authentication

Symptoms: Authentication times out before completionSolutions:

Increase timeout:

ntcli auth login --timeout 120000  # 2 minutes

Check network connectivity:

curl -I https://clerk.nimbletools.ai
ping clerk.nimbletools.ai

Disable firewall/proxy temporarily:

# Test without proxy
unset http_proxy https_proxy
ntcli auth login

Token and Credential Issues

Authentication Expired

Symptoms: Authentication token expired or 401 UnauthorizedSolutions:

Re-authenticate:

ntcli auth logout ntcli auth login

Refresh workspace tokens:

ntcli token refresh --no-expiry

Check token status:

ntcli auth status 
ntcli token show

Workspace Issues

Workspace Sync and Access Problems

Workspaces Missing Locally

Symptoms: Can’t see or access workspaces that exist on the serverSolutions:

Check workspace sync status:
```
ntcli workspace sync
```
Get access tokens for missing workspaces:
```
ntcli token refresh <workspace-name>
```
Verify workspace is now available:
```
ntcli workspace list
```

Workspace Storage Issues

Symptoms: Workspace commands failing or behaving unexpectedlySolutions:

Debug local workspace storage:
```
ntcli workspace debug
```
Check for detailed file contents (if needed):
```
ntcli workspace debug --verbose
```
Compare local and server state:
```
ntcli workspace sync
```
Fix authentication issues:
```
ntcli auth logout
ntcli auth login
```

Token Expiration Issues

Symptoms: ntcli workspace debug shows expired tokensSolutions:

Check token status:
```
ntcli workspace debug
```
Refresh expired tokens:
```
ntcli token refresh <workspace-name>
```

Verify all workspaces are accessible:

ntcli workspace list
ntcli workspace sync

Workspace Creation Problems

Invalid Workspace Name

Symptoms: Invalid workspace name format errorCause: Workspace name violates naming rulesSolution: Follow naming conventions:

# ❌ Invalid names 
ntcli workspace create "my project"
# spaces 
ntcli workspace create my_project 
# underscores
ntcli workspace create very-long-workspace-name-here 
# too long 
ntcli workspace create my-project!
# special chars 
# ✅ Valid names 
ntcli workspace create my-project # good
ntcli workspace create data-science-2024 # good ntcli workspace create
prod-env # good

Workspace Already Exists

Symptoms: Workspace name already exists error Solutions:

List existing workspaces:

ntcli workspace list

Use different name:

ntcli workspace create my-project-v2

Switch to existing workspace:

ntcli workspace switch my-project

Workspace Quota Exceeded

Server Deployment Issues

Deployment Failures

Server Not Found in Registry

Symptoms: Server 'xyz' not found in registrySolutions:

Check available servers:

ntcli registry list

Search for similar names:

ntcli registry list | grep -i keyword

Get exact server ID:

ntcli registry show server-name

Deployment Timeout

Symptoms: Deployment hangs or times outSolutions: 1. Check deployment status:

ntcli server list
ntcli server info server-name

View deployment logs:

ntcli server logs server-name --lines 50

Retry deployment:

ntcli server remove server-name --force
ntcli server deploy server-name

Resource Quota Exceeded

Symptoms: Resource quota exceeded during deploymentSolutions:

Check current resource usage:

ntcli server list

Scale down or remove unused servers:

ntcli server scale server-name 1 
ntcli server remove unused-server

Runtime Issues

Server Not Responding

Symptoms: MCP calls fail with connection errorsSolutions:

Check server status:

ntcli server info server-name
ntcli server logs server-name --lines 20

Test MCP connection:

ntcli mcp connect server-name --verbose

Restart server (scale to 0 then back up):

ntcli server scale server-name 0
sleep 10
ntcli server scale server-name 1

Missing Environment Variables

Symptoms: Server logs show missing required environment variablesSolutions:

Check required secrets:

ntcli registry show server-name
# Look for required environment variables

Set missing secrets:

ntcli secrets set API_KEY=your-key-here
ntcli secrets set DATABASE_URL=postgres://...

Restart server after setting secrets:

ntcli server scale server-name 0
ntcli server scale server-name 1

MCP Integration Issues

Claude Desktop Integration

Claude Can't Find MCP Server

Symptoms: Claude Desktop doesn’t show MCP tools or shows connection errorsSolutions:

Verify server is running:

ntcli server list
ntcli server info server-name

Test MCP connection directly:

ntcli mcp connect server-name
ntcli mcp tools server-name

Regenerate Claude Desktop config:

ntcli server claude-config server-name --insecure
# Copy output to claude_desktop_config.json

Restart Claude Desktop after config changes

MCP HTTP Bridge Issues

Symptoms: @nimbletools/mcp-http-bridge connection failuresSolutions:

Test bridge manually:

npx @nimbletools/mcp-http-bridge \
  --endpoint "https://mcp.nimbletools.ai/v1/workspaces/your-workspace/servers/server-name/mcp" \
  --token "your-token" \
  --insecure

Check network connectivity:

curl -H "Authorization: Bearer your-token" \
  "https://mcp.nimbletools.ai/v1/workspaces/your-workspace/servers/server-name/mcp"

Clear npx cache (if bridge seems outdated):
```
npx clear-npx-cache
# or
rm -rf ~/.npm/_npx
```

SSL Certificate Issues

Network and Connectivity Issues

API Connection Problems

Connection Timeout

Symptoms: ETIMEDOUT or ECONNREFUSED errorsSolutions:

Check API endpoint:

echo $NTCLI_API_URL
curl -I $NTCLI_API_URL/health

Test DNS resolution:

nslookup mcp.nimbletools.ai
ping mcp.nimbletools.ai

Check firewall/proxy settings:

# Temporarily disable proxy
unset http_proxy https_proxy
ntcli health

Proxy Configuration

Symptoms: Connection issues in corporate networksSolutions:

Configure proxy settings:

export http_proxy=http://proxy.company.com:8080
export https_proxy=http://proxy.company.com:8080
export no_proxy=localhost,127.0.0.1

NPM proxy configuration:

npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080

Test connectivity:
```
ntcli health --verbose
```

Performance Issues

Slow Operations

Slow Server Deployment

Symptoms: Server deployment takes unusually longSolutions:

Check network connection:

curl -w "@curl-format.txt" -o /dev/null -s $NTCLI_API_URL/health

Monitor deployment progress:

ntcli server deploy server-name --verbose --wait

Use smaller resource limits:

ntcli server deploy server-name --cpu "100m" --memory "128Mi"

Slow MCP Calls

Symptoms: MCP tool calls take a long time to respondSolutions:

Check server logs for errors:

ntcli server logs server-name --lines 50

Scale up server resources:
```
ntcli server scale server-name 2
```

Test MCP call timing:

time ntcli mcp call server-name tool-name --arg key=value
