The same\nmodel that wrote the code is also the one telling you it works, with no\nindependent check in between — which is exactly why AI-written diffs so\noften look right and aren't.\n\nHyperBox gives the agent somewhere to actually run the change:\n\n```\ncreate_sandbox()  →  run(code)  →  run(fixed code)  →  destroy_sandbox()\n```\n\n`run` returns real stdout, stderr and an exit code the agent didn't\ngenerate and can't talk its way around — so the agent can fix its code\nand try again, and \"it works\" stops being a claim you take on faith. As a\nside effect, none of this touches your machine, your files, or your\ncredentials while it happens.\n\n## What your agent gets\n\nFour tools, and nothing else:\n\n| Tool | What it does |\n|---|---|\n| `create_sandbox(language, backend, environment, packages, sync_from)` | A persistent, disposable container, with any declared packages installed before it is sealed, and optionally a directory of yours copied in. Returns a `sandbox_id`. |\n| `run(sandbox_id, code, libraries, timeout)` | Executes code. Returns `{stdout, stderr, exit_code, success, timed_out}`. |\n| `run(sandbox_id, code, background=True)` | Starts something that keeps running — a server, a worker — and returns a `process_id` instead of output. |\n| `get_process_logs(sandbox_id, process_id)` | Reads what a background run has printed. |\n| `destroy_sandbox(sandbox_id)` | Tears it down. Idempotent, and confirmed against the engine before claiming success. |\n\nPlus a `hyperbox://capabilities` resource publishing the exact limits, so\nan agent can read them instead of discovering them by failing.\n\n**Five languages** — `python`, `javascript`, `bash`, `go` and `java` — each\non an official tagged image.\n\n**Declare dependencies at creation.** `packages=[\"requests\"]` installs while\nthe sandbox may still …","publisher":{"name":"Sanjay Jat","url":null},"homepage":"https://sanjay7089.github.io/hyperbox-mcp/","repository":"https://github.com/Sanjay7089/hyperbox-mcp/blob/main/CHANGELOG.md","version":"0.4.3","license":null,"protocols":["mcp"],"tags":["mcp","model-context-protocol","sandbox","docker","podman","llm","agent","code-execution","container"],"pricing":null,"endpoints":[{"url":"pypi:hyperbox-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"code.execution","name":"Code Execution","confidence":1,"provenance":"declared"},{"slug":"dev.package-management","name":"Packages & Dependencies","confidence":1,"provenance":"derived"},{"slug":"infra.cloud","name":"Cloud Platforms","confidence":1,"provenance":"declared"},{"slug":"dev.filesystem","name":"Filesystem","confidence":0.802,"provenance":"derived"}],"categories":["code","dev","infra"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"hyperbox-mcp","registry":"pypi","observedAt":"2026-09-15T16:22:22.361Z","publishedAt":"2026-09-14T15:01:11.881606Z","latestVersion":"0.4.3"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"hyperbox-mcp","url":"https://pypi.org/project/hyperbox-mcp/","firstSeenAt":"2026-09-09T17:21:44.127Z","fetchedAt":"2026-09-15T16:21:21.066Z","normalizedAt":"2026-09-15T16:21:21.066Z"}]},"firstSeenAt":"2026-09-09T17:21:44.127Z","updatedAt":"2026-09-15T16:22:22.361Z"}
