Best JavaScript MCP Servers
JavaScript is a high-level, interpreted programming language that is one of the core technologies of the World Wide Web. It's a versatile language that allows developers to create interactive elements on websites and is widely used for web development, game development, and creating web applications.
Why this server?
Provides the JavaScript SDK for integrating real-time messaging and media into web applications.
Why this server?
Enables execution of JavaScript code in a browser environment through the browsercat_evaluate tool, allowing interaction with web pages and manipulation of web content.
AlicenseBqualityDmaintenanceA Model Context Protocol server that provides browser automation capabilities using BrowserCat's cloud browser service. This server enables LLMs to interact with web pages, take screenshots, and execute JavaScript in a real browser environment without needing to install browsers locally.7116MITWhy this server?
Implement and run trading strategies via the embedded JavaScript (QuickJS) binding of the FLOX framework. Includes scaffolding support.
flox-mcpofficial
AlicenseAqualityAmaintenanceMCP server for the FLOX trading framework. About 30 tools to run backtests, scaffold strategies, validate for lookahead bias, compute indicators, place orders, and query PnL from Claude/Cursor.37219MITWhy this server?
Allows use of JavaScript interpreter to calculate objective values for optimization problems.
Optuna MCP Serverofficial
AlicenseBqualityBmaintenanceA Model Context Protocol server that enables automated optimization and analysis using Optuna, allowing LLMs to perform hyperparameter optimization and interactively analyze optimization results via chat interfaces.2685MITWhy this server?
Supports building JavaScript LLM applications with vector database memory capabilities powered by Chroma, enabling embedding-based retrieval for context augmentation.
Chroma MCP Serverofficial
AlicenseAqualityDmaintenanceA server that provides data retrieval capabilities powered by Chroma embedding database, enabling AI models to create collections over generated data and user inputs, and retrieve that data using vector search, full text search, and metadata filtering.13584Apache 2.0Why this server?
Supports JavaScript rendering for dynamic content when converting webpages to Markdown.
Skrape MCP Serverofficial
AlicenseBqualityDmaintenanceThis server converts webpages into clean, structured Markdown optimized for language model consumption, removing unnecessary content and supporting JavaScript rendering.112MITWhy this server?
Generates JavaScript code snippets for interacting with blockchain APIs
AlicenseBqualityDmaintenanceEnables natural language access to blockchain data and insights through the Seitrace API. Supports querying address details, token information (ERC-20, ERC-721, ERC-1155, CW20, CW721), transaction data, and smart contract details across multiple blockchain networks.598MITWhy this server?
Supports iterative JavaScript development with built-in presets for running test suites and linters.
AlicenseAquality-maintenanceAn enhanced Model Context Protocol (MCP) server implementing the Ralph Wiggum technique for iterative, self-referential AI development loops.13142Why this server?
Provides efficient code navigation, symbol location, and context extraction for JavaScript codebases to minimize token usage.
AlicenseAqualityDmaintenanceEnables efficient code navigation and retrieval through natural language search, BM25 ranking, and fuzzy matching across multiple programming languages. It drastically reduces token usage by allowing Claude to query specific code symbols and logic instead of reading entire files.133413MIT
