Build, configure, validate, sanitize, and export Model Context Protocol (MCP) server definitions (`mcpServers`) for Claude Desktop, Cursor, Zed, and Windsurf AI agents. 100% client-side privacy guarantees zero network transmission of local file paths or secret keys.
No environment variables defined for this server.

}Choose from starter presets (Filesystem, Brave Search, Memory, GitHub, Postgres, Fetch, Puppeteer) or define custom STDIO command runners and SSE URLs.
Add arguments, environment variables, and auto-approval flags. The built-in scanner flags unmasked hardcoded secrets and offers placeholder replacement.
Select your target client format (`claude_desktop_config.json`, `.cursor/mcp.json`, or Zed `settings.json`) and copy or download the file instantly.
Zero server network requests. Your API keys, database connection strings, local file paths, and environment secrets stay strictly inside your browser memory.
Export pristine JSON configuration formats for Claude Desktop (`claude_desktop_config.json`), Cursor (`.cursor/mcp.json`), Zed (`settings.json`), and custom agent frameworks.
One-click starter templates for Filesystem, Brave Search, Memory, GitHub, PostgreSQL, Fetch, Puppeteer, and Custom STDIO/SSE transports.
Automatically detects unmasked hardcoded secrets or sensitive env tokens and offers environment variable placeholders (`${ENV_VAR}`) to prevent token leakage.
Parses and validates MCP server definitions against official Model Context Protocol specifications with line numbers and diagnostic hints.
Copy formatted config blocks to your clipboard or download ready-to-use `.json` files directly to your local machine.
Our MCP configuration tool is open source under HiMat Technology. Star the repo, inspect the source, or submit contributions on GitHub.
Unlike remote configuration tools that log environment variables or database connection strings, HiMat's generator operates 100% inside your web browser. Neither your file system directory paths, GitHub tokens, Postgres connection URIs, nor Brave API keys ever leave your machine.
Model Context Protocol (MCP) is an open standard developed by Anthropic that enables AI models and desktop clients (like Claude Desktop, Cursor, and Zed) to securely connect to external tools, local file systems, databases, and APIs.
No. The HiMat MCP Server Config Generator operates 100% locally in your web browser. Neither your server commands, arguments, environment variables, nor API tokens leave your local device.
For Claude Desktop on macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`. On Windows: `%APPDATA%\Claude\claude_desktop_config.json`. For Cursor: create or edit `.cursor/mcp.json` in your project root.
Our local scanner inspects `env` object keys and values for common sensitive token patterns (such as `sk-`, `ghp_`, `bearer`, or database passwords) and alerts you to replace raw secret values with environment variables before committing configurations to git.
