Overview

What is Rxjs Mcp Server?

Rxjs Mcp Server is an unofficial community MCP server that lets AI assistants like Claude execute, debug, and visualize RxJS streams. It provides tools for stream execution, marble diagram generation, operator analysis, memory leak detection, and pattern suggestions.

How to use Rxjs Mcp Server?

Install globally with npm install -g @shuji-bonji/rxjs-mcp or use via npx @shuji-bonji/rxjs-mcp. Add the server configuration to your MCP client (e.g., Claude Desktop, VS Code, Cursor) using npx @shuji-bonji/rxjs-mcp as the command and argument. Once configured, you can invoke the available tools (e.g., execute_stream, generate_marble, detect_memory_leak) from your AI assistant.

FAQ from Rxjs Mcp Server

Is Rxjs Mcp Server an official RxJS project?

No, it is an unofficial community project and not affiliated with the RxJS team.

How does Rxjs Mcp Server keep code execution safe?

The execute_stream tool runs user-provided code in an isolated Worker thread to prevent main process pollution, resource leaks, and access to sensitive Node.js APIs. Execution is forcefully terminated if it exceeds the configured timeout.

What tools are available in Rxjs Mcp Server?

Five tools: execute_stream, generate_marble, analyze_operators, detect_memory_leak, and suggest_pattern. Each tool focuses on a specific aspect of RxJS development.

How do I configure Rxjs Mcp Server for my editor?

Add the server definition to your MCP configuration file. For Claude Desktop use ~/Library/Application Support/Claude/claude_desktop_config.json, for VS Code use .vscode/mcp.json, and for Cursor use ~/.cursor/mcp.json. All use npx @shuji-bonji/rxjs-mcp as the command.

What patterns are included in the `suggest_pattern` tool?

Available patterns include http-retry, search-typeahead, polling, websocket-reconnect, form-validation, state-management, cache-refresh, and more. Each pattern provides a production-ready implementation with explanation.
