Devicecloud

devicecloud-mcp

Triage failing DeviceCloud runs so your agent can fix them, without opening the dashboard.

When a DeviceCloud run goes red in CI, the reason why is buried in the web dashboard: the fail reason, the failure screenshot, the logs. This server pulls all of it straight into your editor, so your AI assistant (Claude Code, Cursor, Claude Desktop, etc.) can read the evidence, find the root cause, and fix the flow or app code. You commit, CI re-runs, and the dashboard stays closed.

DeviceCloud is a platform for running Maestro flows on real devices. Your CI triggers the runs; this server is how you debug the ones that fail.

It lets the assistant:

• diagnose a run in one call: failed flows, fail reasons, failure-screenshot paths, and a passed/failed/flaky summary, ready to act on
• rank suite health: classify every flow as healthy, flaky, broken, or regression over a window so you know what's worth fixing first
• list recent uploads, filter by name (commit message + short SHA) or date
• read per-flow status and failReason for any upload
• pull the JUnit XML report
• download and auto-unzip the HTML report (with failure screenshots highlighted)
• download raw artifacts (logs, screenshots, video) as a zip
• spot flaky vs genuinely-broken flows with per-flow pass-rate analytics
• drill into run history for a specific flow file

The server is read-only against the DeviceCloud REST API: no dcd CLI dependency, and nothing an agent does can trigger billable runs. Triggering and re-running tests stay with your CI; cancelling a run stays in the dashboard.

Install

Requires Node.js 22+ — check with node --version. There's no separate install step; the server runs on demand via npx.

Add this to your MCP client config:

{
  "mcpServers": {
    "devicecloud": {
      "command": "npx",
      "args": ["-y", "devicecloud-mcp"],
      "env": {
        "DEVICE_CLOUD_API_KEY": "<your-key>"
      }
    }
  }
}

Get your API key at console.devicecloud.dev/settings.

Claude Code: add it with one command

Skip editing JSON — register the server in one step:

claude mcp add devicecloud --env DEVICE_CLOUD_API_KEY=<your-key> -- npx -y devicecloud-mcp

Add -s user to make it available in every project instead of only the current one.

Configure your assistant

The config block above is the same for every client; only the file location differs.

Claude Code (project-scoped, .mcp.json)

Add to a .mcp.json at the root of any project where you want the tools available:

{
  "mcpServers": {
    "devicecloud": {
      "command": "npx",
      "args": ["-y", "devicecloud-mcp"],
      "env": {
        "DEVICE_CLOUD_API_KEY": "${DEVICE_CLOUD_API_KEY}"
      }
    }
  }
}

Then export the key from your shell profile so Claude Code's child process inherits it:

# ~/.zshrc or ~/.bashrc
export DEVICE_CLOUD_API_KEY="<your-key>"

Setting it only in an interactive shell isn't enough; Claude Code spawns the MCP from its own environment, so the variable needs to be in the profile.

Claude Code (user-scoped, ~/.claude.json)

If you want it available everywhere instead of per-project, add the same devicecloud block under mcpServers in ~/.claude.json.

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows). Restart Claude Desktop after saving; a tools icon appears in the chat input once the server connects.

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json at the project root (project-scoped).

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json.

Other MCP-compatible clients

Any client that supports stdio MCP servers uses the same { command, args, env } shape. Consult the client's docs for the config file location.

Note: OpenAI products (ChatGPT, Codex, the Assistants API) use their own tool protocol and do not support MCP servers.

Verify

After restarting your assistant:

List recent DeviceCloud uploads, limit 3.

You should see a JSON-shaped response with an uploads array. If instead you get DEVICE_CLOUD_API_KEY env var is required, the variable isn't reaching the spawned process; re-check that it's exported from your shell profile (not just the current shell).

Available tools

Upload-naming convention

Uploads are typically named after the commit or build that triggered them. A common convention is to include the short SHA:

fix(login): handle expired session (a1b2c3d4)

Filter with name = "*a1b2c3d4*" to find every upload for a specific commit. The wildcard is *, not %.

When uploads do and don't exist

DeviceCloud uploads are created when you trigger a run, via the CLI, a CI step, the GitHub Action, or the API directly. Whether a given commit has an upload depends entirely on your CI setup. If list_uploads returns nothing for a SHA you expect, the run probably wasn't triggered for that commit.

Troubleshooting

• DEVICE_CLOUD_API_KEY env var is required: the variable isn't visible to the spawned MCP. Export it from ~/.zshrc / ~/.bashrc, restart your assistant.
• unzip failed (from get_html_report): the unzip binary is missing or crashed. Install with brew install unzip (macOS ships with it; Linux usually does too).
• HTTP 401 / 403: the API key is wrong or revoked. Regenerate it at console.devicecloud.dev/settings.
• Empty list_uploads for your SHA: a run probably wasn't triggered for that commit. See "When uploads do and don't exist" above.
