About ClueoMCP
What Is ClueoMCP
ClueoMCP is the open source MCP server built by Clueo Foundation. It plugs into any Model Context Protocol client and applies personality traits to AI output before a model ever generates it. The idea is simple: instead of retyping "be professional" in every chat, you set a personality once and every connected tool follows it.
The product leans on the Big Five psychological model. Each of the five traits, openness, conscientiousness, extraversion, agreeableness, and neuroticism, runs on a 1 to 10 scale, so you can dial in a voice numerically rather than describing it in prose. Eight presets handle the common cases: Professional, Creative, Empathetic, Analytical, Enthusiastic, Casual Friend, Luxury Brand, and Startup Brand.
The biggest limitation is scope. ClueoMCP shapes how text reads, not what a model knows or which model you use. It works only inside MCP clients, and most useful features beyond basic injection want an API key from Clueo. The core injection engine is also patent-pending, so the fully open code covers basic use while advanced enterprise tools sit behind a commercial license.

Key features
Big Five Personality Control
ClueoMCP scores every output against the five Big Five traits on a 1 to 10 scale. You set openness, conscientiousness, extraversion, agreeableness, and neuroticism as numbers, then the server applies them to your text. It's a precise alternative to describing a tone in words and hoping the model reads it the same way twice.
Eight Ready-Made Personality Presets
The server ships with eight personalities that cover most everyday needs, from Professional and Analytical to Enthusiastic and Luxury Brand. Each personality preset is a fixed set of trait scores, so you get a predictable voice without tuning anything yourself. Call inject_preset_personality with a preset name and your text to use one.
Cross-Platform Consistency
This cross-platform approach means the same personality follows you into Claude Desktop, ChatGPT, Cursor, Windsurf, and VS Code. ClueoMCP applies traits through the shared MCP standard, so the voice doesn't reset when you change tools. For teams juggling several AI apps, this removes the usual drift between drafts.
Adaptive Memory System
The server remembers the personalities you use most and suggests them by context. Ask for get_memory_suggestions on a customer email and it might reply that you often pair empathetic with professional. A project-level memory lets you save a default personality for specific work, so recurring tasks start with the right voice.
Enterprise Brand Management
Organizations can push one brand personality across all company AI use. Admins define department variations, monitor compliance, and control who can edit the brand voice. Tools like inject_brand_personality and validate_brand_compliance support the workflow. This layer needs a commercial license.
API-First Integration
ClueoMCP is built as an MCP server first, so it slots into any MCP-compatible AI rather than tying you to one vendor. Developers can call the Clueo API directly to put personality into their own apps. Real-time processing applies traits before generation, not as a post-editing pass over finished text.
Pros and cons
Pros
- Applies one personality across many AI tools, cutting repeated prompt writing.
- Uses the peer-reviewed Big Five model with numeric 1 to 10 control.
- Eight presets cover common business and creative tones out of the box.
- Open source and MIT licensed, so basic use costs nothing and installs from npm.
- Adaptive memory learns your preferences and suggests personalities by context.
Cons
- Personality shaping only changes tone, not the model's knowledge or accuracy.
- Works only inside MCP clients, so plain web chat apps without MCP support are out.
- Full features need a Clueo API key, which adds a signup step for basic tiers.
- Advanced enterprise tools sit behind a commercial license despite the open repo.
