File Context Server MCP Server: Enhanced Data Access for Large Language Models

Overview: What is File Context Server MCP Server?

The File Context Server (FCS) is an MCP (Model Context Protocol) server that provides essential file system context, enabling large language models like Claude Desktop to read, search, and analyze code files. FCS supports advanced caching mechanisms and real-time file watching capabilities, ensuring efficient and up-to-date information for AI applications. By integrating with FCS, developers can extend the functionalities of their AI applications, such as improving code analysis, providing context-aware searches, and enhancing overall performance.

🔧 Core Features & MCP Capabilities

FCS is built around the Model Context Protocol (MCP), allowing it to seamlessly integrate with various AI application clients. Key features include:

File Operations

• Read Directory Contents: FCS can read files from directories with detailed metadata.
• Real-time Watching and Cache Invalidations: Real-time file changes trigger cache invalidations, ensuring that the model always has access to the most current data.
• Multiple Encoding Support: Handles various file encodings, ensuring compatibility across different file types.

Code Analysis

• Cyclomatic Complexity Calculation and Dependency Extraction: These capabilities help in understanding the complexity and dependencies within code files.
• Comment and Quality Metric Analyses: FCS supports metrics such as detecting duplicate lines, long lines, complex functions, line counts, and more.

Smart Caching

• LRU Cache Strategy: Uses an LRU algorithm to manage cache entries based on recent usage.
• Automatic Invalidation on File Changes: Ensures that the cache is updated in real-time without manual intervention.
• Size-Aware Caching with Configurable Limits: Configurable size limits allow for optimal memory usage.

Advanced Search

• Regex Pattern Matching and Context-Aware Results: FCS allows users to search for patterns within files, providing context-aware results.
• Multi-Pattern Support and Results Caching: Supports simultaneous searches and caching of results for efficient retrieval.

⚙️ MCP Architecture & Protocol Implementation

FCS is designed with the Model Context Protocol (MCP) at its core. The protocol ensures seamless integration between the server and various AI application clients, such as Claude Desktop, Continue, Cursor, and others. The architecture involves the following key components:
