Summary
Connects Claude to SchemaStore.org's catalog of 500+ JSON schemas for configuration files, manifests, and data formats. Exposes four tools: list_schemas with optional filtering, find_schema_for to match filenames against glob patterns, fetch_schema to pull down actual schema documents, and exact name lookup. Useful when you're validating JSON files, building editor integrations, or need Claude to understand the structure of package.json, tsconfig.json, GitHub workflows, and similar config formats. Part of the Pipeworx gateway, which means you can also use ask_pipeworx for natural language queries instead of calling tools directly.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.
Tools
| Tool | Description |
|---|---|
list_schemas | List SchemaStore catalog entries. Optional case-insensitive filter on name/description/fileMatch. |
find_schema_for | Find catalog entries whose fileMatch globs cover the given filename. |
fetch_schema | Fetch a JSON Schema document by URL (must be hosted on json.schemastore.org). |
lookup | Exact-name lookup against the catalog (case-insensitive). |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"schemastore": {
"url": "https://gateway.pipeworx.io/schemastore/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 673+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Schemastore data" })
The gateway picks the right tool and fills the arguments automatically.
