Capgo CLI Usage

Route Capgo CLI requests, authenticate the CLI, and connect agents to Capgo.

Facts below were checked against @capgo/cli 8.77 (October 2026). Always run npx @capgo/cli@latest <command> --help before you rely on a rarely used flag.

When to Use

TRIGGER when:

• The user asks "how do I use the Capgo CLI", "which Capgo command does X", or asks about CLI login or auth.
• The user wants Claude, Cursor, ChatGPT, or another agent connected to their Capgo account (MCP).
• The request spans several Capgo areas and the right sub-skill is not clear yet.
• The CLI fails before doing any work (auth, wrong directory, missing appId).

Do not use when one of these already fits. Switch to it as soon as the scope is clear:

• App updater wiring, notifyAppReady, or autoUpdate: capgo-live-updates
• Bundle uploads, channels, rollouts, rollback, or encryption keys: capgo-release-management
• Native cloud builds and signing: capgo-native-builds
• Organizations, members, 2FA, or security policy: capgo-organization-management
• Multi-product Capgo plans (builds, OTA, and store): capgo-cloud
• Ionic or Capacitor's own MCP tooling, not Capgo: capacitor-mcp

Secrets and Confirmation

• Never ask the user to paste a Capgo API key, signing password, .p8 key, keystore, or service-account JSON into the chat. Ask them to run npx @capgo/cli@latest login themselves (it opens the browser or asks for the key in a masked prompt), or to set CAPGO_TOKEN in their shell or CI secret store.
• Do not put secrets in command arguments: they end up in shell history and process lists. Use environment variables, the saved login, or the CLI's interactive prompts.
• If a secret appears in the conversation anyway, do not repeat it, do not write it to a file, and tell the user to revoke it and create a new one.
• npx @capgo/cli@latest downloads and runs the newest CLI from npm. Run it only inside the user's project and with their go-ahead. In CI, pin an exact version.
• Ask before any command that changes remote state: uploading a bundle, changing or promoting a channel, deleting apps, bundles, channels, or keys, requesting a build that uploads to a store, and exporting or deleting credentials. Say what will change and for which app and channel.

Command Surface

These commands do not exist. Do not suggest them: capgo upload (use bundle upload), channel create (use channel add), bundle revert (use channel set --bundle), key verify, upload --sign.

Authentication

The user runs the login. It opens the browser to create a key, or asks for the key in a masked prompt:

npx @capgo/cli@latest login          # saves to ~/.capgo
npx @capgo/cli@latest login --local  # saves to ./.capgo (git-ignored)

The CLI picks the key in this order:

1. -a, --apikey <key> on the command
2. The CAPGO_TOKEN environment variable (use this in CI)
3. ~/.capgo (global)
4. ./.capgo (project)

Trap: the global key wins over the project key. Set the CAPGO_TOKEN environment variable to force a different account. Keys are created at https://console.capgo.app/dashboard/apikeys.

Self-hosted backends: add --supa-host <url> --supa-anon <key> on supported commands.

Connect the Agent to Capgo (MCP)

Capgo has two MCP servers. Use both when available.

• Hosted MCP: https://api.capgo.app/mcp (streamable HTTP). Nothing to install. The client signs in with OAuth, or sends Authorization: Bearer <Capgo API key>. The hosted MCP includes destructive tools, so use an API key with the smallest role the task needs (read-only for reporting). It covers apps, bundles, channels, progressive rollouts, devices, stats, Observe update health, native build status and logs, webhooks, and push notifications. Example for Claude Code: claude mcp add --transport http capgo https://api.capgo.app/mcp, then /mcp to sign in. Each OAuth client gets its own MCP · <client name> API key, which expires after at most 90 days. Revoke a client by deleting that key in the console.
• Local CLI MCP: npx @capgo/cli@latest mcp (stdio, authenticated by login). Use it to upload a bundle from the build folder, request a native build, or run doctor, probe, or compatibility checks against local project files. The hosted MCP cannot read local files.

Claude Desktop config for the local server:

{ "mcpServers": { "capgo": { "command": "npx", "args": ["@capgo/cli@latest", "mcp"] } } }

Setup guide for both servers: https://capgo.app/mcp (a page, not an MCP endpoint).

Diagnostics Quick Path

npx @capgo/cli@latest doctor                         # versions + setup problems (add --package-json for monorepos)
npx @capgo/cli@latest app todo com.example.app       # onboarding checklist: done, skipped, pending
npx @capgo/cli@latest probe --platform android       # would the backend serve an update to this config?
npx @capgo/cli@latest app debug com.example.app      # live update events from a device
npx @capgo/cli@latest observe summary --days 7       # launch, crash, WebView findings, each with a next view

observe has no session ID. Use observe device DEVICE_ID --json to get one device's timeline.

Monorepos

Use --package-json, --node-modules, and, for dynamic root configs, --capacitor-config <path>. Keep the env selector active, for example CAP_APP=web npx @capgo/cli@latest init --capacitor-config ./env-configs/capacitor.config.web.ts.

Verification

• npx @capgo/cli@latest account whoami prints the expected account ID and email, which proves auth works.
• npx @capgo/cli@latest app list shows the app. If it is missing, run app add.
• MCP: in Claude Code, /mcp lists capgo as connected, and a read-only prompt ("list my Capgo apps") returns data.
