About JSONPlaceholder MCP Server

Connect to JSONPlaceholder, the industry-standard fake REST API, to simulate data interactions within your AI workflows. Perfect for developers testing MCP integrations or prototyping agentic behaviors without a real backend.

The OpenAI Agents SDK auto-discovers all 21 tools from JSONPlaceholder through native MCP integration.

Social Interactions — Query comments via list_comments and get_comment to simulate discussion threads and linking.
Media Handling — Explore list_albums, get_album, list_photos, and get_photo to manage hierarchical media metadata.
Task Tracking — Use list_todos to verify state-based logic and completion status in your agents.
Data Filtering — Test precise data retrieval by filtering lists by userId, postId, or albumId directly through tool parameters.

The JSONPlaceholder MCP Server exposes 21 tools through the Vinkius. Connect it to OpenAI Agents SDK in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
