How to Use the JSON Path Query Engine MCP in VS Code Copilot

Q: Does the JSON Path Query Engine work with Copilot enterprise policies?

Yes, because the queryjson tool executes locally within your VS Code Copilot MCP environment. It respects your organization's data boundary policies by keeping raw payload processing entirely local.

Q: What happens if the JSON payload is malformed?

The queryjson tool performs a quick structural check and returns a clear parsing error if the JSON is malformed. This allows the Copilot agent to identify the structural issue in your data file immediately.

Q: How does this tool protect sensitive raw JSON strings in my workspace?

The queryjson tool processes all raw JSON strings locally on your machine, never transmitting the raw payload over the network. Only the final, filtered query results are shared with VS Code Copilot, keeping your sensitive data private.

Let VS Code Copilot query and filter massive JSON payloads locally, keeping your shared team repositories clean and fast.

Team-wide JSON parsing with VS Code Copilot

The `query_json` tool enables your team to parse massive JSON files directly inside VS Code Copilot without committing custom extraction scripts to your repository. By configuring this MCP Server in your shared `.vscode/mcp.json` file, every engineer on the team gains immediate access to standardized data extraction tools. This ensures that your Copilot agent can inspect complex API payloads and logs without hitting context limits. The agent queries the local files, extracts the exact nodes needed, and generates precise code based on the actual data structure.

Local execution for enterprise data files

The `query_json` tool runs queries locally on your workstation to isolate nested properties without uploading raw files to external clouds. This is crucial when using VS Code Copilot in enterprise MCP environments where data compliance rules prevent sharing full database dumps. The tool extracts only the specific arrays or scalar values requested by your query. Only this highly filtered subset is passed to the Copilot chat, maintaining strict compliance while providing the exact context required for code generation.

Automated test data extraction

The `query_json` tool extracts mock data directly from massive production JSON payloads to populate your VS Code Copilot test suites. Instead of manually carving out chunks of a 100MB payload, the agent uses JSONPath to isolate specific test cases. This automates the creation of realistic unit tests. The agent targets the exact nodes required, formats them, and writes them directly into your test files, saving hours of manual data preparation.

Setup guide

Set up JSON Path Query Engine MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the JSON Path Query Engine MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the JSON Path Query Engine tools listed. Try asking: "List my recent JSON Path Query Engine transactions" and Copilot will invoke them automatically.

.vscode/mcp.json
