Neuro MCP V2

Description

Neuro MCP V2 is an advanced, production-grade local Model Context Protocol (MCP) server designed specifically for Claude Desktop. It supercharges Claude with a suite of agentic capabilities, bridging the gap between local execution and AI assistance using standard I/O (stdio) transport.

Key Features

• Persistent Semantic Memory: Utilizes local embedded ChromaDB to store, embed, and instantly recall user context and project insights across different chat sessions.

• Sandboxed File System I/O: Safely reads and writes files asynchronously via aiofiles within a strict, path-traversal-protected workspace/ directory.

• Live Web Research: Interacts with the Tavily Search API via httpx to pull real-time data, documentation, and news directly into Claude's context window.

• Local Emotional Intelligence: Runs a localized Hugging Face DistilRoBERTa pipeline via transformers and torch to analyze the semantic emotional tone of text blocks with zero external API latency.

Architecture & Tech Stack

• Framework: fastmcp (Official Python SDK for MCP)

• Package Management: uv (Fast Python dependency resolution)

• Database: chromadb (Serverless, local SQLite vector storage)

• Machine Learning: transformers, torch

• Async Operations: aiofiles, httpx

Prerequisites

• Python: 3.10 or higher

• Claude Desktop Application

• Tavily API Key: For web search capabilities

Installation

Clone the repository and navigate to the project root. Sync the dependencies using uv:

uv sync

Crucial Pre-flight Step: Run the server manually once to cache the Hugging Face emotion model (~300MB) locally and prevent Claude Desktop initialization timeouts:

uv run src/mymcp/server.py

Press Ctrl + C once the model finishes downloading.

Claude Desktop Configuration

To connect this server to Claude, edit your Claude Desktop configuration file (located at %APPDATA%\Claude\claude_desktop_config.json on Windows). [or simply go to Claude Desktop -> profile -> settings -> developer -> edit config option(if the mcp option is not shown automatically) -> make changes to the file that opens] Point the command to your project's absolute path and supply your API keys in the environment block:

{
  "mcpServers": {
    "neuro-mcp-v2": {
      "command": "C:\\Absolute\\Path\\To\\second_mcp_server\\.venv\\Scripts\\python.exe",
      "args": [
        "C:\\Absolute\\Path\\To\\second_mcp_server\\src\\mymcp\\server.py"
      ],
      "env": {
        "PYTHONUTF8": "1",
        "TAVILY_API_KEY": "your_tavily_api_key_here"
      }
    }
  }
}

Restart Claude Desktop entirely after updating this file. You should see the MCP plug icon appear in your chat window.

Security Notice

This application includes a workspace/ sandbox. The security middleware prevents the AI from reading or writing files outside of this specific directory to protect your local machine. Do not bypass the security.py checks.
