How to Set Up and Use OpenClueo
The OpenClueo MCP Server provides a universal AI personality layer backed by a scientifically-grounded Big Five (OCEAN) personality engine, allowing you to inject consistent character traits and brand voices into any MCP-compatible AI assistant. It exposes tools for applying preset personas (professional, creative, empathetic, analytical, and more), tuning individual Big Five dimensions on a 1–10 scale, simulating responses in a chosen personality, and persisting personality defaults per project. Teams use it to maintain coherent brand voice across Claude, Cursor, Windsurf, and other AI tools without re-prompting each session.

OpenClueo Examples
Client configuration
Add to claude_desktop_config.json. Replace 'your_api_key_here' with your actual Clueo API key.

}
}Prompts to try
Use these prompts to apply personalities and generate on-brand responses through the MCP tools.
- "Apply the 'professional' preset personality and then draft a response to a customer complaint about delayed shipping"
- "Set my personality with openness=8, conscientiousness=9, extraversion=4 and write a technical blog post introduction about microservices"
- "Use the 'luxury brand' preset to respond to: How much does your top product cost?"
- "Save this analytical personality profile as the default for my 'data-reports' project"Troubleshooting OpenClueo
The server returns authentication errors when calling inject_personality
Verify that CLUEO_API_KEY is set correctly in the env block of your MCP config and that the key has not expired. Generate a new key at clueoai.com if needed.
Claude Desktop does not recognize '@openclueo/mcp' as a valid command
Use the full path to the globally installed binary instead. Run 'which @openclueo/mcp' (or 'where @openclueo\mcp' on Windows) and replace the command value in the config with that absolute path.
get_memory_suggestions returns no recommendations
This tool learns from usage history. You need at least a few sessions with inject_personality or inject_preset_personality calls before memory-based suggestions become available.
