+display_name: Trae CN
+description: Add a one-click button to launch Trae CN
+icon: ../../../../.icons/trae-cn.png
+verified: false
+tags: [ide, trae, ai]
+---
+
+# Trae CN
+
+Add a button to open any workspace with a single click in Trae CN.
+
+Uses the [Coder Remote VS Code Extension](https://github.com/coder/vscode-coder).
+
+```tf
+module "trae_cn" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder/trae-cn/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.main.id
+}
+```
+
+## Examples
+
+### Open in a specific directory
+
+```tf
+module "trae_cn" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder/trae-cn/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.main.id
+  folder   = "/home/coder/project"
+}
+```
+
+### Configure MCP servers for Trae CN
+
+Provide a JSON-encoded string via the `mcp` input. When set, the module writes the value to `.trae/mcp.json` in `folder`, or `$HOME/.trae/mcp.json` when `folder` is not set.
+
+If your MCP configuration includes credentials, either add `.trae/mcp.json` to the project's `.gitignore`, or set `mcp_config_path` to a path outside the repository.
+
+The following example configures Trae CN to use the GitHub MCP server with authentication facilitated by the [`coder_external_auth`](https://coder.com/docs/admin/external-auth#configure-a-github-oauth-app) resource.
+
+```tf
+module "trae_cn" {
+  count    = data.coder_workspace.me.start_count
+  source   = "registry.coder.com/coder/trae-cn/coder"
+  version  = "1.0.0"
+  agent_id = coder_agent.main.id
+  folder   = "/home/coder/project"
+  mcp = jsonencode({
+    mcpServers = {
+      "github" : {
+        "url" : "https://api.githubcopilot.com/mcp/",
+        "headers" : {
+          "Authorization" : "Bearer ${data.coder_external_auth.github.access_token}",
+        },
+        "type" : "http"
+      }
+    }
+  })
+}
+
+data "coder_external_auth" "github" {
+  id = "github"
+}
+```
