What is the 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.
What you can do
- Post Management — Use
list_posts,get_post,create_post,update_post,patch_post, anddelete_postto test full CRUD lifecycles. - Social Interactions — Query comments via
list_commentsandget_commentto simulate discussion threads and linking. - Media Handling — Explore
list_albums,get_album,list_photos, andget_phototo manage hierarchical media metadata. - Task Tracking — Use
list_todosto verify state-based logic and completion status in your agents. - Data Filtering — Test precise data retrieval by filtering lists by
userId,postId, oralbumIddirectly through tool parameters.
How it works
- Subscribe to this server
- No real API key is required for this public service, but you can provide a placeholder string if prompted
- Start prototyping your data-driven agents immediately
Who is this for?
- MCP Developers — verify that your client correctly handles tool calls, pagination, and JSON responses
- AI Researchers — prototype complex agent behaviors that require structured data interaction without setting up a database
- Product Designers — demonstrate AI-driven workflows using realistic (but safe) mock data

Frequently asked questions
Can I filter posts by a specific user?
Yes! Use the list_posts tool with the userId parameter to retrieve only the posts created by that specific user ID.
Does creating or updating a post actually save the data?
No. JSONPlaceholder is a fake API. Tools like create_post, update_post, and delete_post simulate the response as if the action succeeded, but the server state remains unchanged.
How do I find comments for a specific post?
Use the list_comments tool and provide the postId. This will return all comments associated with that specific post ID.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
