• Ensure key is in correct RS256 format
• Check PROJECT_ID is correct for your account
• Regenerate keys if necessary

Integration Not Available

Symptoms: Service not found errors, Integration disabled messages

Cause: Integration not enabled in Paragon project or LIMIT_TO_INTEGRATIONS restriction

Solution:

• Enable required integrations in Paragon dashboard

• Check integration-specific requirements

User Authorization Required

Symptoms: OAuth flow errors, Permission denied messages

• Verify PORT is not in use by another service
• Check firewall settings allow connections
• Test endpoint with curl: curl http://localhost:3001/health

MCP Server Creation Fails

Symptoms: Server generation errors, Deployment failures, Tool discovery issues

Cause: Insufficient context or invalid server specifications

Solution:

• Provide more specific details about server requirements
• Check that API credentials are correctly configured
• Review Memex logs in Control Center for detailed error messages
• Use existing templates as starting points for complex servers
• Ensure local development environment has necessary dependencies

Template Detection Not Working

Symptoms: .memex/rules.md not loaded, Generic responses instead of specialized behavior

Cause: Repository not properly cloned or rules file missing

Solution:

• Verify template was fully cloned from GitHub
