Can the agent truly issue a real, functioning corporate card?

Yes! The `brex_create_card` logic specifically maps to creating a virtual limit card. By default, it operates completely valid via Visa/Mastercard configurations matching Brex internals. The agent handles setting its name and tying it strictly to the user id.

What acts as the final authentication key for Brex?

You only need a `User Token`. Brex explicitly supports personal workflow automation using `user_tokens` which perfectly mimic your permissions. It typically begins literally with the string `user_token_` followed by hashes.

Will vendor payments via AI require external 2FA from my side?

To enforce safety in the integration, the `approval_type` parameter when sending vendor money defaults to `'MANUAL'`. This means the AI structures all the math, formatting, routing inputs perfectly but leaves the final 'Accept' button queued on your dashboard.

How can I see my user lists across Brex?

Run a request on `brex_list_users`. The AI will natively stream the company's organizational tree mapping the emails to Brex UUIDs required for triggering corporate card injections.

Brex + VS Code Copilot FAQ

Common questions about integrating Brex 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.
