Overview

AI-generated overview

Lets an assistant build and manage a JSONPad backend: lists, items, indexes, write rules, schema sync, history, and flows.

What it does
Connects an assistant to JSONPad so it can create and operate a JSON backend. Tools are grouped into toolsets: lists, items, indexes, history, rules, schema (the defaults), plus flows and identities. It can read and write data, manage indexes and write rules, sync schemas, and inspect history.
When to use it
Useful when you want an assistant to set up or maintain a JSONPad-backed API without leaving the chat: defining lists and schemas, adding or editing items, tuning indexes and rules, or reviewing history and flows.
Requirements
A JSONPad account and an API token, supplied as the JSONPAD_API_TOKEN environment variable or as an Authorization bearer header. The remote endpoint at mcp.jsonpad.io can also connect via OAuth without a token. The npm package @basementuniverse/jsonpad-mcp runs locally over stdio and needs Node.js.
Before you install
The token is a secret credential; keep it out of shared configuration. Tools can create, change, and delete lists, items, indexes, rules, and schemas, so set JSONPAD_READ_ONLY=true to register only non-mutating tools when you just want to inspect. Restrict JSONPAD_TOOLSETS to limit which capabilities are exposed.
