TrueVoice MCP

Tools to eliminate AI slop from text

Model Context Protocol server with tools to detect and eliminate AI slop from text. Based on expert annotations from NLP writers and philosophers analyzing AI-generated text patterns.

What is AI Slop?

Low-quality AI text characterized by:

• Information Utility: Low content density, irrelevant filler, factual errors

• Style Quality: Repetitive structures, corporate clichés ("delve into", "leverage")

• Structure: Excessive verbosity, poor coherence, formulaic patterns

Research foundation: arXiv:2509.19163v1

Available Tools

get_human_writing_rules

Get comprehensive anti-slop writing rules tailored to your context.

Parameters:

• context (optional): Writing type (e.g., "technical blog", "email", "docs")

Example:

Get writing rules for a technical blog post

check_for_slop

Analyze text for AI slop indicators across three dimensions.

Parameters:

• text (required): The text to analyze

Example:

Check this for slop: "In today's digital landscape, it's important to
note that we should leverage cutting-edge solutions to deliver a
seamless user experience..."

Returns:

⚠️ AI Slop Analysis

- Overused Phrases: Found AI clichés - landscape, it's important to note,
  leverage, cutting-edge, seamless
- Verbosity: Overly long sentences (avg 28.5 words)
- Word Complexity: Unnecessarily formal - "utilize" → "use"

Recommendation: Revise to be more concise, direct, and natural.

get_slop_examples

Get categorized examples of AI slop patterns to avoid.

Parameters:

• category (optional): "phrases", "structure", "tone", or "all"

Example:

Show me phrase examples to avoid

What Gets Detected

Slop Phrases

• "delve into" → "explore"

• "leverage" → "use"

• "it's important to note" → just state it

• "robust", "seamless", "holistic", "paradigm shift"

• "cutting-edge", "game changer", "synergy"

Structural Issues

• Repetitive sentence starts (same word 3+ times)

• Excessive bullet points and lists

• Overly formal language for casual contexts

• Long sentences (>25 words average)

• Low lexical density (<40% unique words)

Research-Based Scoring

Text analyzed across three weighted dimensions:

• Information Utility (β=0.06) - Content density, relevance

• Style Quality (β=0.05) - Repetition, coherence, naturalness

• Structure (β=0.05) - Verbosity, bias, flow

Development

Prerequisites

• Node.js 18+

• TypeScript 5.6+

• npm or pnpm

Local Setup

git clone https://github.com/howdoiusekeyboard/truevoice-mcp
cd truevoice-mcp
npm install
npm run build

Available Scripts

• npm run build - Compile TypeScript

• npm run dev - Watch mode for development

• npm start - Run stdio server locally

• npx ultracite check - Lint check

• npx ultracite fix - Auto-fix issues

Testing Locally

Test stdio transport (Claude Desktop):

npm run build
npm start
# Server runs on stdio, test with MCP inspector:
npx @modelcontextprotocol/inspector node dist/index.js

Test HTTP transport (Cursor/Web):

vercel dev
# Visit http://localhost:3000

Dual Transport Support

stdio Transport (Local/Claude Desktop):

• Direct process communication

• Low latency, persistent connection

• Best for local development

• Entry: dist/index.js

Streamable HTTP Transport (Vercel/Web):

• POST-only mode (MCP 2024-11-05 spec)

• Fully stateless, serverless-optimized

• No SSE (Vercel 60s timeout limitation)

• Auto-scaling on demand

• Endpoint: /api/mcp

Technology Stack

• Runtime: TypeScript 5.6+ with Node.js ESM modules

• Validation: Zod schemas for type safety

• Linting: Ultracite (Biome-powered)

• MCP SDK: @modelcontextprotocol/sdk v1.19+

• Deployment: Vercel serverless functions

Deploy Your Own

One-Click Deploy

Manual Deploy

npm install
vercel deploy --prod

Your MCP endpoint: https://your-project.vercel.app/api/mcp

Environment Variables

None required! Server works out of the box.

Usage Examples

API Integration

# Check text for slop
curl -X POST https://truevoice-mcp.kushagragolash.dev/api/check \

Research Foundation

Based on expert annotations from:

• NLP researchers and writers

• Professional philosophers

• Industry content creators

Key Findings:

• Relevance (β=0.06) - Most significant slop indicator

• Content Density (β=0.05) - Substantive vs. filler content

• Natural Tone (β=0.05) - Conversational vs. robotic voice

• Human perception correlation: AUROC 0.52-0.55
