Frequently asked questions

What is JSONPad?

Build and run a JSONPad backend: lists, items, indexes, write rules, schema sync, history, flows.

How do I install JSONPad?

It runs as a remote server. In Claude Code: claude mcp add --transport http jsonpad 'https://mcp.jsonpad.io/api' --header 'Authorization: <Bearer <token>, with one of your JSONPad API tokens. Optional: without it, the client connects with OAuth>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does JSONPad need an API key?

Yes. It expects JSONPAD_API_TOKEN, Authorization, which you set in its configuration.

Who maintains JSONPad?

It is published by io.jsonpad. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
