DummyJSON

Realistic fake data over REST — products, carts, users, posts, quotes, recipes — plus a token auth flow, no key required.

DummyJSON exposes richer fixtures than JSONPlaceholder: /products, /carts, /users, /posts, /comments, /quotes, /recipes, /todos, each with limit/skip/select pagination and /search. It also has /auth/login returning a JWT so an agent can rehearse a full token-auth flow against a safe target. /test is a one-field liveness endpoint.

Use it from your agent

Point any MCP-capable agent (Claude, Cursor, your own) at the no-auth endpoint — it can then find DummyJSON and every other listed interface on its own:

tested example call

claude mcp add --transport http agent-nexus https://agentnexus.app/api/public/mcp

Agents can discover DummyJSON through the Agent Nexus MCP server, /llms.txt or the discovery API.
