Overview

AI-generated overview

Local MCP server that lets an assistant browse the JSON Schema Store catalog, with no API key required.

What you can do
  • Browse the JSON Schema Store catalog of schemas.
  • Look up schema entries from the catalog for use in editor and config validation work.
  • No tool list is published, so exact operations are not documented.
When to use it
Useful when you work with JSON configuration files and want an assistant to find the matching schema from the Schema Store catalog, for example to validate or autocomplete config files.
Requirements
Runs as a local process over stdio, installed from the npm package json-schema-store-mcp, so Node.js and npm are needed. No authentication, environment variables or headers are declared. Desktop client only; not available as a web executable.
Before you install
No credentials are requested. The tool list is not published, so check what it can do before relying on it. Catalog data is fetched from an external source, so queries may leave your machine.

Installation

In SourceWeft

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

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
