Overview

Json Schema Validator is a Model Context Protocol server that validates JSON data against JSON Schema specifications and reports any violations found. It requires x402 payment in testnet USDC to operate. Any MCP-compatible AI assistant can invoke the server's tools directly during conversations or agent runs, with the model determining when validation is needed.

The server runs as a remote, hosted service at https://faceted-napped-debtless.ngrok-free.dev/json-schema-validator/mcp with no local installation required. Authentication is not needed. The latest release is v1.0.92934.

Json Schema Validator appears in the Finance category on mcp.site and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and others. Maintainers can claim this listing to verify ownership, display a Verified badge, and ensure information stays accurate.
