About this tool

What MCP Config Builder does

MCP Config Builder is a visual configuration tool hosted by DevBolt that generates MCP configuration files for Claude Desktop, Cursor, VS Code, Windsurf, and Claude Code. Users select their target client, add servers using one of 16 templates (including filesystem, GitHub, Slack, and Postgres), and configure transport and arguments through structured fields. The tool outputs a ready-to-use config file that can be copied or downloaded, with all processing occurring entirely within the user's browser. The generated output follows a standard mcpServers structure with command and args fields, providing immediate usability for the selected development environment.

Questions

MCP Config Builder FAQ

Can I use MCP Config Builder offline?
No, the tool requires an internet connection to load the DevBolt website, but all configuration processing happens entirely in your browser once loaded, meaning your data never leaves your device.
What types of MCP servers can I create with the templates?
The 16 available templates include common servers like filesystem (read-only), GitHub, Slack, Postgres, SQLite, and other development-related integrations that connect your AI assistant to external data sources and tools.
Do I need technical knowledge to use this tool?
Basic familiarity with your target development environment is helpful, but the visual builder interface eliminates the need to write JSON manually, making it accessible for users who want to configure MCP servers without coding knowledge.
Can I create custom MCP servers not in the templates?
Yes, the builder includes a 'create a blank server' option that allows you to define custom servers with specific commands, arguments, and environment variables tailored to your particular needs.

HTML Entity Encoder3 options

Developers and web designers often need to convert special characters into their corresponding HTML entities to ensure proper rendering across different browsers. HTML Entity Encoder provides a reliable method to transform sensitive characters—such as angle brackets, ampersands, and quotes—into standardized code that prevents browsers from misinterpreting them as functional HTML tags. This process is essential for anyone looking to display raw code snippets on a webpage or securely manage user input within a web application. The utility also integrates XSS prevention analysis, offering insights into how specific encoding choices contribute to site security. By substituting potentially malicious characters with safe entities, it helps mitigate the risk of cross-site scripting attacks that target vulnerabilities in data handling. Users can switch between encoding and decoding functions to verify their data or restore entities to their original plaintext format for editing and review.
