MCP Playground

A demonstration Model Context Protocol (MCP) server implementation in Go featuringreal-time bidirectional file communication.

- Real-Time Communication: Bidirectional file-based communication with live notifications
- MCP Resources: Live-updating resources with automatic change notifications
- File Monitoring: External file changes detected and reported in real-time
- Rich Tool Set: Complete set of tools for file interaction and monitoring

# Build the server task build # Start monitoring and interact with the file task run

- start_file_monitoring- Start real-time file monitoring
- write_to_file- Write messages to communication file
- read_communication_file- Read current file contents
- get_recent_changes- Get list of recent external changes
- get_monitoring_status- Check monitoring status

- file://communication- Live communication file with real-time updates

# Test real-time notifications ./test_realtime_resources.sh # Test basic file monitoring ./test_file_monitoring.sh

Copy configuration to your Claude Desktop config:

{ "mcpServers": { "mcp-playground": { "command": "/path/to/mcp-playground/bin/mcp-playground", "args": [] } } }

- Start monitoringwithstart_file_monitoringtool
- External changestocommunication.txtare detected automatically
- Real-time notificationssent via MCPnotifications/resources/updated
- Claude Desktopreceives live updates and can react to external changes

Perfect for experimenting with MCP real-time capabilities! 🎪

MCP server for AI Diagram Maker — generate beautiful software engineering diagrams directly inside Cursor, Claude Desktop, Claude Code, or any MCP-compatible AI agent

MCP server that gives AI assistants on-demand access to 1,500+ amCharts docs, ~300 code examples, and 1000+ class API references.

One shared context layer for AI agents and humans — live API specs, DB schemas, and versioned contracts across repos so every agent and teammate works from the same source of truth.

Local stdio MCP server that lets AI coding agents read and maintain structured architecture, rules, and decisions directly from your repository.

The MCP server for Bitrix24 provides AI assistants with structured access to the Bitrix24 API. It delivers up-to-date method descriptions, parameters, and valid values, allowing assistants to work with precise data instead of guesswork. This reduces code errors and accelerates Bitrix24 integration development.

Official Context7 MCP server that brings up-to-date, version-specific library documentation and code examples into AI coding prompts.
