MCP Config Validator

Paste your mcpServers (or VS Code servers) JSON below to catch mistakes before your AI client silently fails to load a server.

Why Validate Before Restarting Your Client

A single misplaced comma or a missing command field is enough to make an MCP client quietly skip a server on startup, usually with no error message pointing at the actual cause. Tracking that down by trial and error — edit, save, fully restart the client, check if it worked — is slow.

Frequently Asked Questions (FAQ)

The most common syntax errors are trailing commas after the last server entry, unescaped backslashes in Windows file paths, and unquoted property keys or strings.
