Libb Cognitive Clarity — MCP Server

Score any message through 15 clinical cognitive assessment gates before it reaches a human.

Built on clinical speech-language pathology research, Libb measures whether a message is cognitively processable — not just grammatically correct, but actually understandable by the person reading it.

Why this exists

Every day, workplace communications fail — not because they contain errors, but because they exceed the cognitive processing capacity of the reader. Policy updates buried in passive voice. Action items hidden inside nested clauses. Deadlines expressed as "in the near future."

These aren't style problems. They're cognitive accessibility barriers that disproportionately impact neurodivergent employees, non-native speakers, and anyone under cognitive load.

Libb Cognitive Clarity gives AI agents and automation platforms the ability to catch these barriers before messages ship.

Installation

npm install -g libb-cognitive-clarity

Quick Start — Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "libb-cognitive-clarity": {
      "command": "libb-cognitive-clarity"
    }
  }
}

Restart Claude Desktop. You can now ask Claude to analyze any text for cognitive clarity.

Quick Start — Claude Cowork

Add to your Cowork MCP configuration:

{
  "mcpServers": {
    "libb-cognitive-clarity": {
      "command": "npx",
      "args": ["-y", "libb-cognitive-clarity"]
    }
  }
}

The 15 Cognitive Execution Gates

Every message is scored across 15 clinical assessment gates derived from the proprietary CCVM (Cognitive-Communication Vulnerability Mapping) Framework:

| # | Gate | |---|------| | 1 | Ambiguity Load | | 2 | Inference Demand | | 3 | Action Burial | | 4 | Hedge Density | | 5 | Passive Deflection | | 6 | Temporal Vagueness | | 7 | Jargon Saturation | | 8 | Cognitive Stacking | | 9 | Referential Ambiguity | | 10 | Negative Framing | | 11 | Modal Confusion | | 12 | Format Accessibility | | 13 | Emotional Tone Masking | | 14 | Cultural Load | | 15 | Processing Bottleneck |

Each gate applies clinically-derived assessment criteria to identify specific cognitive friction patterns. The assessment methodology is protected under pending patent applications.

Cognitive Processability Score (CPS)

Every analysis returns a Cognitive Processability Score indicating how accessible the message is to the broadest range of readers, including neurodivergent individuals, non-native speakers, and those under cognitive load.
