How to add JsonPlace MCP to Claude Code

Install in Claude Code by pointing it at https://jsonplace.com/mcp. Public mode works without any auth header, and you can add your JsonPlace API key later for saved templates and endpoint management.

Start in public mode

Terminal command
claude mcp add --transport http --scope user jsonplace https://jsonplace.com/mcp

Optional: add account features

Terminal command
claude mcp add --transport http --scope user --header "Authorization: Bearer jpak_your_real_key_here" jsonplace https://jsonplace.com/mcp

When you need the API key

Public mode covers fake JSON, field discovery, one-off endpoint creation, and public response lookup. Add your API key only if you want saved templates and endpoint management.
