Trigger on the keyword "legba" — e.g. "use legba to access/fetch this", "legba this URL", "route this through legba". Also use when a public target blocks datacenter IPs, is geo-restricted, sits behind a Cloudflare/anti-bot JS challenge, or needs a captcha, login code or 2FA that only a person can do — provisions a residential exit, or a browser on Legba's own infrastructure that the user can take over mid-task and hand back. Keywords - legba, residential proxy, datacenter block…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Legba

Get onto the open web from an address and a browser that are not obviously a robot's.

**This needs a key before it can do anything.** The exits and the hosted browser are a service Legba
runs; these scripts are a client for it. Every one of them fails with the same message if no key is
stored, and that message tells you what to do.

If there is no key, ask the user for theirs **once**. If they have no account, give them both links:
sign up at **https://app.legba.xyz/signup** (Free, no card) and copy the key from
**https://app.legba.xyz/api-key**. If they would rather not have an account, say that this skill
cannot help and stop — do not go looking for another way onto the site, and do not keep retrying.

Nothing here ever spends their money on its own: when a plan does not cover what you asked for, the
answer is a `402` naming the limit and the upgrade link, and you stop and show it to them.

Four rungs, lightest first. Climb only as far as the target forces you:

| | Rung | What it is | When |
|-|------|------------|------|
| 1 | plain fetch | `curl` through a residential exit | the default |

How to install

The exact contents, by fingerprint
mdr add legba-app/skills/legba@sha256:1e9cafd35f322912

The line at the top of this page pins the label git:20261029.cfddff4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
