fifteenA/mobilebox

Mobilebox gives your AI agent a phone it can use. Claude Code, Codex, Cursor or your own agent loop creates a cloud Android 14 phone, reads the screen as numbered elements, taps, types, installs your APK, then parks or deletes the phone. One phone per task or pull request costs a few cents: $0.01 per phone-minute, billed per second.
Measured, 2026-11-08 (method, scripts and CSV): a Mobilebox phone was ready for its first screenshot in 19.4 s (median of 10) and a 10-minute session cost $0.10. On a GitHub Actions runner, the same start took 20.3 s, against 50 s for the Android emulator with KVM and 813 s without it (one run).
Fair comparison: in the same benchmark Limrun started in 0.98 s ($0.04 a minute on its $20 plan), and Clousd lists a lower price ($0.004 a minute, as published on 2026-11-10). All cloud phones for AI agents, compared.

MCP registry
Phone screens are unedited API screenshots from one recorded run; steps and times are its MCP calls, from the home screen on. Playback shortened.
Ready time: create to ready, three runs on 2026-11-04 ( RUNS.md ).
Works with  
 Claude Code  
 Codex  
 Cursor  
 any MCP client
Listed in the official MCP registry as dev.mobilebox/mobilebox, tool definitions rated A on Glama.
Checked on every deploy: an end-to-end run on production that uses only the public docs (create, install, tap, type, park, resume, delete over REST and MCP).
## Quickstart
1. Get a key. Sign up with GitHub ($2 of credit, 200 phone-minutes) and create an agent key in the dashboard.
bash
export MOBILESANDBOX_API_KEY=... # keep it in your shell or secret manager, never in a prompt
2. Add Mobilebox to your agent.
bash
claude mcp add --transport http mobilebox https://mobilebox.dev/mcp \
--header "Authorization: Bearer $MOBILESANDBOX_API_KEY"
Codex, Cursor, a shared .mcp.json , other clients
Codex, ~/.codex/config.toml:
toml
[mcp_servers.mobilebox]
url = "https://mobilebox.dev/mcp"
bearer_token_env_var = "MOBILESANDBOX_API_KEY"
Cursor: the Add to Cursor button above installs the URL alone and Cursor signs you in over OAuth, no key. Or .cursor/mcp.json with the key:
json
{ "mcpServers": { "mobilebox": { "url": "https://mobilebox.dev/mcp", "headers": { "Authorization": "Bearer ${env:MOBILESANDBOX_API_KEY}" } } } }
Claude Code, shared through a committed .mcp.json without the key in it. Keep "type": "http", or Claude Code treats the entry as a stdio server:
json
{ "mcpServers": { "mobilebox": { "type": "http", "url": "https://mobilebox.dev/mcp", "headers": { "Authorization": "Bearer ${MOBILESANDBOX_API_KEY}" } } } }
Other clients: any MCP client with Streamable HTTP and a custom header. Hand-written clients also send Accept: application/json, text/event-stream. The registry entry is server.json.
3. Give it a task.
> Use Mobilebox. Create a phone, open Settings and tell me which Android version it runs. Delete the phone at the end, even if a step fails.
Next: let your agent test the APK you just built, or run the same check in CI. No MCP client? curl/walkthrough.sh does the whole loop over REST (OpenAPI, reference).
