How to Set Up and Use Clueo

ClueoMCP is a personality layer for MCP-compatible AI assistants, powered by Clueo's Big Five personality engine. It lets you inject consistent personality traits — openness, conscientiousness, extraversion, agreeableness, and neuroticism — into any LLM session, either by specifying exact scores or by applying named presets. This makes it practical for product teams building AI assistants with consistent brand personas, or researchers exploring how personality parameters affect response style.

Prerequisites

  • Node.js 16 or later installed
  • An MCP-compatible client such as Claude Desktop
  • A Clueo API key from https://clueoai.com (required for CLUEO_API_KEY)
  • The Clueo backend endpoint (default: https://backend.clueoai.com)
1

Install the package globally

Install the @openclueo/mcp package globally via npm so it is available as a command for your MCP client.

npm install -g @openclueo/mcp
2

Obtain a Clueo API key

Sign up at clueoai.com and create a project to receive your CLUEO_API_KEY. This key authenticates all personality injection requests.

3

Add to Claude Desktop configuration

Open your Claude Desktop config file and add the clueo-mcp entry, supplying your API key and the backend URL as environment variables.

{
  "mcpServers": {
    "clueo-mcp": {
      "command": "npx",
      "args": ["clueomcp"],
      "env": {
        "CLUEO_API_KEY": "your_clueo_api_key_here",
        "CLUEO_API_URL": "https://backend.clueoai.com"
      }
    }
  }
}
4

Restart Claude Desktop

Fully quit and reopen Claude Desktop so the new MCP server is loaded and the Clueo tools become available in your session.

5

Test with a personality preset

In a Claude conversation, ask it to apply a personality preset to verify the server is connected and responding correctly.

Clueo Examples

Client configuration

Claude Desktop configuration for ClueoMCP with required environment variables.

{
  "mcpServers": {
    "clueo-mcp": {
      "command": "npx",
      "args": ["clueomcp"],
      "env": {
        "CLUEO_API_KEY": "your_clueo_api_key_here",
        "CLUEO_API_URL": "https://backend.clueoai.com",
        "LOG_LEVEL": "info"
      }
    }
  }
}

Prompts to try

Example prompts to explore personality injection and preset application via ClueoMCP.

- "Apply the 'professional' personality preset to this conversation."
- "Inject a personality with openness=9, conscientiousness=8, extraversion=4, agreeableness=7, neuroticism=3 and then greet the user."
- "Save the current personality settings as the default for this project."
- "Show me usage analytics for the personalities applied this week."
- "Simulate how someone with high agreeableness and low neuroticism would respond to a difficult customer complaint."

Troubleshooting Clueo

Tools return 401 Unauthorized errors

Double-check that CLUEO_API_KEY is set correctly in the env block of your MCP config and that the key is active in your Clueo dashboard.

The server starts but no personality tools appear in Claude

Ensure you restarted Claude Desktop after editing the config file. Also confirm the JSON is valid — a missing comma or bracket will prevent the server from loading.

inject_personality returns validation errors on trait scores

Each Big Five trait must be an integer from 1 to 10. Scores outside this range or non-integer values will be rejected by the Clueo API.
