Query Customer Segments in VS Code

`list_chattermill_projects` fetches the exact workspace keys your team needs to investigate user feedback. VS Code Copilot uses this identifier to target specific product lines without you having to hunt down IDs in a separate browser tab. `list_custom_segments` pulls your user-defined cohorts straight into the editor. Your agent filters responses by these segments, helping you isolate bugs affecting specific groups like enterprise users or mobile app testers.

Debug with Raw Response Details

`list_feedback_responses` grabs up to 100 paginated customer comments at a time, filtered by date. When a new release goes out, Copilot pulls the latest feedback directly into your IDE to see what users are reporting. `get_response_details` retrieves the full text, assigned score, and metadata for any concerning review. Your agent reads the exact customer complaint and cross-references it with your recent commits to find the root cause.

Track NPS via Chattermill MCP Server

`get_chattermill_metric` calculates net sentiment and volume for your project using UNIX timestamps. Copilot checks these numbers to tell you if the last deployment negatively impacted customer satisfaction. `list_theme_categories` pulls the high-level parent groupings of customer complaints. Your agent maps these categories to your codebase, showing you exactly which feature area needs immediate attention.

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.

Common questions about Chattermill MCP in VS Code Copilot

Hit Cmd+Shift+P and select MCP: Open User Configuration to edit your global settings. Add the server details to the JSON file and ensure you are running VS Code 1.96 or higher.

Yes, create an mcp.json file inside your .vscode directory and commit it to version control. Every developer on the team automatically gets access to the same MCP Server tools.

The agent runs a list command to fetch all available classification types, like surveys or app reviews. It uses these exact keys to narrow down the feedback it queries.

You can pass a comment string to the submit tool directly from the chat panel. The agent pushes the text and optional source keys to your workspace immediately.

The Vinkius architecture relies on ephemeral, zero-trust execution environments for every single tool call. Your raw customer reviews, metadata, and calculated NPS scores never persist on disk after the command finishes running inside the V8 Isolate Sandbox.
