Troubleshooting
Common Issues
API Key Invalid or Missing
Symptoms: 401 Unauthorized errors, Authentication failed messages, API key not found
Cause: PERPLEXITY_API_KEY environment variable not set or invalid
Solution:
- Verify API key is set: echo $PERPLEXITY_API_KEY
- Obtain valid key from https://www.perplexity.ai/account/api
- Ensure key is exported in shell: export PERPLEXITY_API_KEY="pplx-xxx"
- Check for typos or extra whitespace in key value
Connection Timeout
Symptoms: Request timeout errors, Server not responding, Long delays with no response
Cause: Network issues or timeout too short for deep research queries
Solution:
- Increase timeout: export PERPLEXITY_TIMEOUT_MS=900000
- Check internet connectivity
- Verify firewall allows outbound HTTPS to api.perplexity.ai
- For deep research, expect longer response times (2-5 minutes)
Proxy Configuration Errors
Symptoms: Connection refused, Proxy authentication failed, Network unreachable in corporate environment
Cause: Incorrect or missing proxy configuration for enterprise networks
Solution:
- Set proxy: export PERPLEXITY_PROXY=https://user:pass@proxy:port
- Alternative: export HTTPS_PROXY=https://proxy:port
- Verify proxy credentials are correct
- Contact IT if proxy blocks API requests
NPX Installation Fails
Symptoms: npx command not found, Package download errors, Permission denied
Cause: Node.js not installed or npm registry issues
Solution:
- Install Node.js 18+ from https://nodejs.org
- Clear npm cache: npm cache clean --force
- Try with explicit version: npx -y perplexity-mcp@latest
- Check npm registry connectivity
Strip Thinking Parameter Not Working
Symptoms: Response contains <think>...</think> tags, Excessive context token usage
Cause: strip_thinking parameter not passed correctly
Solution:
- Include strip_thinking: true in perplexity_reason calls
- This removes internal reasoning from responses
- Reduces token usage while preserving final answers
Platform Access Issues
Symptoms: Cannot log in, Dashboard not loading
Cause: Account or browser issues
Solution:
- Verify account credentials and status
- Try different browser or clear cache
- Check internet connectivity
- Contact Daydreams support for account issues
MCP Server Connection Failed
Symptoms: Server not connecting, Connection timeout
Cause: Server configuration or network issues
Solution:
- Verify server endpoint URL is correct
- Check server authentication configuration
- Ensure server is running and accessible
- Test server connectivity from other tools
Agent Not Using MCP Tools
Symptoms: Agent running but not using tools, Limited capabilities
Cause: Agent configuration or tool assignment issues
Solution:
- Verify tools are properly assigned to agent
- Check agent configuration and permissions
- Review agent behavior and trigger conditions
- Test with simpler tool usage scenarios
Perplexity MCP Server not appearing in Daydreams Agents
Symptoms: Server not listed, Tools not available
Cause: Configuration or installation issue
Solution:
- Verify configuration syntax
