Unbrowse for Virtualbox (virtualbox.org)

Virtualbox as tools for your agent. Unofficial: not affiliated with or endorsed by virtualbox.org. Unbrowse compiled these from virtualbox.org's own requests: each call replays the site's first-party API server-side and returns a verified result. No scraping of rendered pages, no browser on your side, no virtualbox.org API key.

Connect the virtualbox.org MCP

This server is a tool scope holding only virtualbox.org: its compiled tools plus the Unbrowse tools that run them, so the agent's tool list stays small and every call stays on virtualbox.org.

claude mcp add --transport http virtualbox https://unbrowse.ai/mcp/virtualbox.org
codex mcp add virtualbox --url https://unbrowse.ai/mcp/virtualbox.org && codex mcp login virtualbox

{"mcpServers":{"virtualbox":{"url":"https://unbrowse.ai/mcp/virtualbox.org"}}}

The first connect signs in to Unbrowse with OAuth (free tier, only verified results count). For scripts, send Authorization: Bearer $UNBROWSE_API_KEY (key from https://unbrowse.ai/app/keys; keep it in a secret manager, never in config you commit).

If none of the tools below are in this session's tool list, the server is not connected or not signed in: say so and stop. Do not fetch virtualbox.org some other way and present it as this skill's result.

Tools

virtualbox_org__get_search — Search virtualbox.org

Search virtualbox.org with its own search (homepage search form) and read the results page as title, text and links. One first-party HTTP request, no browser. Inputs: query. Returns the page's title, readable text and links. Read-only on virtualbox.org.

• query (string, required) — query — what to search for on virtualbox.org

{"query":"changelog"}

virtualbox_org__render_page — Search VirtualBox site

Search VirtualBox site. Inputs: query. Returns the page's title, readable text and links. Read-only on virtualbox.org.

• query (string, required) — query — what to search for on virtualbox.org

{"query":"<query>"}

virtualbox_org__read_page — Read a page on virtualbox.org

Read any page on virtualbox.org — a path such as /news/2026/some-story, or a full virtualbox.org URL — and get its title, readable text and links. One first-party HTTP request, no browser. Follow a returned link by passing its href back as the path. Inputs: path e.g. "/". Returns the page's title, readable text and links. Read-only on virtualbox.org.

• path (string, required) — A page on virtualbox.org: a path like /about, or a full URL on virtualbox.org

{"path":"/"}

Always there too: unbrowse.run (a task on virtualbox.org in plain words), unbrowse.inspect, unbrowse.resume, unbrowse.scrape and unbrowse.map (any page on virtualbox.org), and the recorded cloud browser unbrowse.browse.open → unbrowse.browse.act → unbrowse.browse.finish. Hosts that reject dotted names show them with _ (unbrowse_run).

How to call

1. Pick the tool whose title matches the job and pass its inputs. Leave the site's recorded parameters out unless the user asked for something they control.
2. Read status. succeeded carries the verified result. input_required is not a failure: answer the open fields with unbrowse.resume {runId, answers} on the same run.
3. No tool fits: unbrowse.run {task}. It fails with no_capability when nothing is compiled for that yet: do it once with unbrowse.browse.open on virtualbox.org → unbrowse.browse.act → unbrowse.browse.finish, which compiles a new tool this server lists next time. Anything off virtualbox.org is refused here (not_in_scope): use the general Unbrowse server for that.
4. Signing in: never ask the user for a password. unbrowse.browse.act with action: "autofill" fills virtualbox.org's login from their Unbrowse password manager.
5. Report only what a succeeded result says. outcome_unknown means a change may have happened: check before retrying. Posting, buying, sending or deleting needs the user's go-ahead.

Without MCP

Every tool is also a REST call:

curl -s https://unbrowse.ai/api/v1/sites/virtualbox.org/call/virtualbox_org__get_search \
  -H "authorization: Bearer $UNBROWSE_API_KEY" -H "content-type: application/json" \
  -d '{"query":"changelog"}'

OpenAPI: https://unbrowse.ai/api/v1/sites/virtualbox.org/openapi.json. Every other site: the general Unbrowse skill (https://github.com/unbrowse-ai/unbrowse) and https://unbrowse.ai/mcp.
