Overview

AI-generated overview

Remote MCP server with one tool that validates JSON against a JSON Schema and lists the violations found.

What you can do
  • Validate a JSON document against a supplied JSON Schema
  • Return the list of schema violations found in the input
When to use it
Useful when an assistant needs to check that generated or edited JSON conforms to a schema and report exactly what fails, without running a validator locally.
Requirements
Remote streamable HTTP endpoint; no authentication, environment variables or headers are declared. Each call requires an x402 payment in USDC on Base mainnet, so a wallet able to pay x402 charges is needed.
Before you install
The tool is paid per use via x402 in USDC on Base mainnet, so calls spend real funds; the endpoint is third-party hosted and receives the JSON and schema you submit.

Installation

In SourceWeft

  1. Open Json Schema Validator in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.ryuamarines%2Fjson-schema-validator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
