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.

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.

What you can do

Post Management — Use list_posts, get_post, create_post, update_post, patch_post, and delete_post to test full CRUD lifecycles.
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.

JSONPlaceholder + VS Code Copilot FAQ

Common questions about integrating JSONPlaceholder MCP Server with VS Code Copilot.

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.
