Unbrowse for Liftoff (liftoff.ai)

Liftoff as tools for your agent. Unofficial: not affiliated with or endorsed by liftoff.ai. Unbrowse compiled these from liftoff.ai'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 liftoff.ai API key.

Connect the liftoff.ai MCP

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

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

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

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 liftoff.ai some other way and present it as this skill's result.

Tools

liftoff_ai__get_search — Search liftoff.ai

Search liftoff.ai 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 liftoff.ai.

• query (string, required) — query — what to search for on liftoff.ai

{"query":"mobile"}

liftoff_ai__read_page — Read a page on liftoff.ai

Read any page on liftoff.ai — a path such as /news/2026/some-story, or a full liftoff.ai 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 liftoff.ai.

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

{"path":"/"}

Always there too: unbrowse.run (a task on liftoff.ai in plain words), unbrowse.inspect, unbrowse.resume, unbrowse.scrape and unbrowse.map (any page on liftoff.ai), 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 liftoff.ai → unbrowse.browse.act → unbrowse.browse.finish, which compiles a new tool this server lists next time. Anything off liftoff.ai 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 liftoff.ai'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/liftoff.ai/call/liftoff_ai__get_search \
  -H "authorization: Bearer $UNBROWSE_API_KEY" -H "content-type: application/json" \
  -d '{"query":"mobile"}'

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