# Chargebee L1 · Needs a person Chargebee sells billing and subscription software. **Can an AI agent use Chargebee? No.** Our agent couldn't get into Chargebee on its own. Category: Billing and subscriptions · Connects by: MCP, API, SDK · Agent payments: None found · Driven: 28 Oct 2026 **How to connect** - CLI install: `npm install -g @chargebee/cli` (documented). Source: https://www.chargebee.com/docs/cli/overview - Docs page: `https://apidocs.chargebee.com/docs/api/getting-started` (tested in our drive). Source: https://apidocs.chargebee.com/docs/api/getting-started **Level 1: Needs a person.** Agents can't get in on their own. - Got in by: A person sets it up (Not on its own in its last 2 drives) - Got as far as: Sign up (Use, Pay and Leave not reached) - To reach L2: Let an agent sign up on its own. 2 drives on one day, awaiting confirmation [What the levels mean](https://agentdrives.com/method/levels?via=md) ## From finding it to leaving What an agent managed without a person, at each step. 1. **Find**: On its own. Docs it can act on: llms.txt, an OpenAPI and an MCP server. 556 doc pages read. 2. **Get in**: Stopped. Can't sign up. The docs show keys made only in the web app, and no account existed. Stopped here. 3. **Use**: Not reached. Tasks need an account. 4. **Pay**: Not reached. Buying needs an account. 5. **Leave**: Not reached. Nothing to cancel or delete. ## Getting in None of the 4 ways in worked without a person. Where it stopped: **Email and password**. Trial sign-up diverted to a sales demo. - Both kinds of agent (On a server, or in its own browser): No. Signing up needs a person: the form refused our agent's browser. - Signed agent (Known to Cloudflare): Partly. The sign-up page opens. The check on the form still applies. | Way in | What happened | |---|---| | Email and password | Refused | | Sign-in for apps (OAuth, MCP) | Not tried: Not part of this drive | | Added by an admin | Not tried: Not part of this drive | | A key from a person | Not tried: Needs a person's account | - Crawlers: **robots.txt asks crawlers to stay off sign-up and the API.** Nothing to fix. It keeps these pages out of search and doesn't stop agents signing up.
