Model Context Protocol (MCP) Server - Filesystem Implementation

What is Model Context Protocol (MCP) Server - Filesystem Implementation?

This is an educational implementation of a Model Context Protocol (MCP) server in Go using the Echo framework. It provides access to the local filesystem through MCP tools and resources, demonstrating how to create secure, two‑way connections between data sources and AI‑powered tools.

How to use Model Context Protocol (MCP) Server - Filesystem Implementation?

Prerequisites are Go 1.24 or higher. Clone the repository, run go mod tidy to install dependencies, then start the server with go run main.go. By default it listens on port 8080; set the PORT environment variable to change it. Use the API endpoints (POST /v1/discover, POST /v1/call-tool, POST /v1/load-resource) to discover capabilities and call tools like filesystem.list, filesystem.read, filesystem.write, and filesystem.delete.

Key features of Model Context Protocol (MCP) Server - Filesystem Implementation

• Filesystem provider via MCP tools and resources
• Tools: list, read, write, and delete files/directories
• Resources: file and directory representations
• Basic path sanitization to prevent directory traversal
• Educational implementation with Echo framework in Go

Use cases of Model Context Protocol (MCP) Server - Filesystem Implementation

• Learn how to build an MCP server for filesystem access
• Prototype AI‑powered tools that read or write local files
• Demonstrate secure data source connections in educational environments
• Experiment with MCP protocol endpoints without production overhead

FAQ from Model Context Protocol (MCP) Server - Filesystem Implementation

What is the Model Context Protocol (MCP)?

MCP is an open standard that enables developers to build secure, two‑way connections between their data sources and AI‑powered tools.

Is this implementation production‑ready?

No. It includes basic path sanitization but is intended for educational purposes only. Production use requires user authentication, rate limiting, audit logging, sandboxing, and more robust input validation.

What are the runtime dependencies?

Go 1.24 or higher and the Echo framework (installed via go mod tidy). No external database or cloud services are required.

How can I change the default port?

Set the PORT environment variable to a different value before starting the server.

What transport and authentication does the server use?

The server exposes HTTP endpoints (no TLS by default) and does not implement any authentication. Security must be added externally for any non‑educational deployment.
