How to Use the Duo Security (Two-Factor Authentication API) MCP in VS Code Copilot

Q: How do we share the Duo Security (Two-Factor Authentication API) configuration across our team in VS Code Copilot?

Create a .vscode/mcp.json file in your repository root and commit it to Git. Once your team members open the workspace in VS Code, Copilot will automatically discover the Duo tools.

Q: Can VS Code Copilot check our team's remaining Duo Security (Two-Factor Authentication API) credits?

Yes. Copilot can run gettelephonycredits to check your available balance. If your team is running low, the agent can also execute settelephonycredits if your API key has administrative permissions.

Q: How does VS Code Copilot handle user deletion in Duo Security (Two-Factor Authentication API)?

The agent uses trashusers to safely stage users for deletion. This keeps them in the Duo trash for 7 days, allowing you to run restoreusers if you need to reverse the action.

Secure your team workflows and manage Duo Security user access directly from VS Code Copilot.

Team-wide Duo admin tools inside VS Code Copilot

Share your security management tools across your entire engineering team. By committing the configuration to your repository, every developer gets instant access to the Duo Security MCP Server. Your team can run `list_users` to debug access issues or check user settings with `modify_user` without sharing admin console credentials. Everything is tracked through your existing VS Code environment.

Trigger and monitor 2FA requests during deployment

Build security gates directly into your development inner loop. VS Code Copilot uses this MCP Server to trigger a push challenge using `auth` before running sensitive deployment commands. The agent tracks the approval state using `auth_status` to block or allow the action. This turns your 2FA setup into an interactive gatekeeper inside your editor.

Provision new developers instantly from your editor

Onboard new engineers to your Duo tenant without leaving your workspace. Your agent runs `create_user` to set up individual profiles or `bulk_create_users` for entire cohorts. Once created, the agent checks their integration status using `preauth` to ensure they can register their security keys. It keeps your team moving without administrative bottlenecks.
