MCP Config Validator

Check MCP server JSON and convert portable configurations between mcpServers and VS Code servers.

Processing happens in your browser. Your inputs, files and results stay on this device.

Server configuration

Paste only the MCP configuration. Replace keys, passwords and private paths with placeholders.

Validation result

See the problem paths or a compatible conversion here.

Check an MCP configuration before adding it

Choose the structure used by your client. A local server uses command and optional args. An HTTP server uses url and may include headers.

A command with args set to a single string is flagged. Put each argument in a separate array item.

Limitations

Checks common JSON fields. Client-specific options and variables can block conversion. Servers and commands are never contacted or executed.
