Sync team environments via this MCP Server

The `get_environment_flags` tool exposes your default flag states to VS Code Copilot for team-wide alignment. Because the configuration is committed to your workspace, every developer on the team reads the same flag statuses. When setting up new testing pipelines, `create_environment` lets Copilot spin up clean environments. This keeps your staging setups standardized across the entire engineering group.

Manage user identities in VS Code Copilot

The `identify_user` tool registers test identities and sets custom traits directly from your editor. Copilot uses these traits to simulate different customer tiers during debugging. To verify that targeting works, `get_identity_flags` fetches the active flags for that identity. You can spot-check targeting rules without leaving your active code file.

Modify flag states inline

The `update_flag_v1` tool updates a single flag value directly from your Copilot chat panel. This allows you to toggle features on or off during live debugging sessions. If you are managing complex rollouts, `update_flag_v2` handles batch updates across multiple flags. Your agent runs these changes in a single action to minimize configuration drift.

Setup guide

Set up Flagsmith 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
