CVE-2025-53110info

@modelcontextprotocol/server-filesystem vulnerability allows for path validation bypass via colliding path prefix

Versions of Filesystem prior to 0.6.3 & 2025.7.1 could allow access to unintended files in cases where the prefix matches an allowed directory. Users are advised to upgrade to 2025.7.1 to resolve the issue. Thank you to Elad Beber (Cymulate) for reporting these issues.

README

Model Context Protocol servers

This repository is a collection of reference implementations for the Model Context Protocol (MCP), as well as references to community-built servers and additional resources.

[!IMPORTANT] If you are looking for a list of MCP servers, you can browse published servers on the MCP Registry. The repository served by this README is dedicated to housing just the small number of reference servers maintained by the MCP steering group.

[!WARNING] The servers in this repository are intended as reference implementations to demonstrate MCP features and SDK usage. They are meant to serve as educational examples for developers building their own MCP servers, not as production-ready solutions. Developers should evaluate their own security requirements and implement appropriate safeguards based on their specific threat model and use case.

The servers in this repository showcase the versatility and extensibility of MCP, demonstrating how it can be used to give Large Language Models (LLMs) secure, controlled access to tools and data sources. Typically, each MCP server is implemented with an MCP SDK:

🌟 Reference Servers

These servers aim to demonstrate MCP features and the official SDKs.

Everything - Reference / test server with prompts, resources, and tools.
Fetch - Web content fetching and conversion for efficient LLM usage.
Filesystem - Secure file operations with configurable access controls.
Git - Tools to read, search, and manipulate Git repositories.
Memory - Knowledge graph-based persistent memory system.
Sequential Thinking - Dynamic and reflective problem-solving through thought sequences.
Time - Time and timezone conversion capabilities.

Archived

The following reference servers are now archived and can be found at servers-archived.

AWS KB Retrieval - Retrieval from AWS Knowledge Base using Bedrock Agent Runtime.
Brave Search - Web and local search using Brave's Search API. Has been replaced by the official server.
EverArt - AI image generation using various models.
GitHub - Repository management, file operations, and GitHub API integration.
GitLab - GitLab API, enabling project management.
Google Drive - File access and search capabilities for Google Drive.
Google Maps - Location services, directions, and place details.
