# MCP Config Validator

Paste your MCP client config (Claude Desktop / Cursor / Cline / Windsurf / Zed style) and get a quick sanity check. Catches the common mistakes (missing `command`, wrong types, empty servers map) before you restart your client.

Sample configs and edge cases live in the companion dataset: [`mcp-config-examples`](https://huggingface.co/datasets/mukunda1729/mcp-config-examples).
