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

Why VS Code Copilot?
GitHub Copilot Agent mode brings JSONPlaceholder data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 21 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

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.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
