About Us

Welcome to MCP Server Validator.

We built this tool because configuring Model Context Protocol (MCP) servers for hosts like Claude Desktop can be incredibly frustrating. A single missing quote or misplaced array in your mcp.json file leads to silent failures, leaving developers guessing what went wrong.

Our goal is to provide a fast, secure, and client-side solution that instantly validates your configuration against the official schema, saving you hours of debugging.

Privacy First

Because MCP configurations often contain sensitive API keys and absolute file paths, we designed this tool to run 100% locally in your browser using WASM-powered JSON schema validation. Your data is never sent to our servers.
