Filesystem MCP

Source Code

Overview

Filesystem MCP is a Node.js/TypeScript-based Model Context Protocol (MCP) server that provides secure, efficient, and token-saving access to project files for AI agents (such as Cline or Claude). It implements a notes system, enabling users to create, access, and generate summaries of text notes via URIs and tools, and is designed as a concrete MCP server implementation for use in AI-driven environments.

Features

• Secure Filesystem Access: Operates within a defined project root directory, confining access for security.
• MCP Protocol Implementation: Provides a robust set of filesystem tools via the MCP protocol for AI agents.
• Notes System: Allows users to create, access, and generate summaries of text notes using URIs and integrated tools.
• Batch Operations: Tools that accept multiple paths or operations process each item individually and return detailed status reports.
• Detailed Error Reporting: Returns comprehensive status and error information for each operation.
• Token Efficiency: Supports batch processing to reduce the number of commands and tokens used by agents.
• Low Latency API: Provides direct API access, reducing overhead compared to shell command alternatives.
• Multiple Installation Methods:
  • Use via npx or bunx for latest version without local install
  • Official Docker image for containerized deployment
  • Local build option for development
• Easy Setup: Designed for straightforward integration with MCP host environments (e.g., Roo/Cline, VSCode).
• MIT Licensed: Open source and free to use and modify.

Installation

• npx/bunx: Recommended for always using the latest version
• Docker: Official Docker image available
• Local Build: For development purposes
