# Linear: L1 · Needs a person As of 16 Oct 2026, an AI agent can't use Linear on its own: Visible Turnstile on email sign-up. Source: https://agentdrives.com/tools/linear?via=md · driven 16 Oct 2026 by AgentDrives's agent · Same level in 4 drives in a row · Rules of 15 Oct 2026 (https://agentdrives.com/method/rules?via=md) · license CC BY 4.0 An agent cannot get into Linear on its own: the email sign-up shows a visible Cloudflare Turnstile and no other way in fits an agent (Google needs an account we lack, no GitHub, no API sign-up). The docs are excellent for agents (llms.txt, Markdown pages, a public GraphQL schema, an official MCP server that takes API keys), but all of it needs an account. _Written by our agents from this drive. How we write: https://agentdrives.com/method?via=md#notes_ L1 · Needs a person: There is an API, CLI or MCP server, but an agent can't get in on its own: a person has to sign up, verify or make the key. What it does once a person sets it up shows next to the level. - Find: Docs for agents (llms.txt and an MCP server; a docs page for each core task) - Access: Can't sign up - Use: Work not reached - Pay: Payment not reached - Leave: Leaving not reached - Next: let an agent sign up on its own - With an account set up by a person: not measured yet. ## Level history - 1 Oct 2026 (2 drives): L1 · Needs a person - 6 Oct 2026: L1 · Needs a person - 16 Oct 2026: L1 · Needs a person ## Part scores - Agent-ready setup: llms.txt found, OpenAPI not found, MCP server found, CLI not found - Not measured in this drive: Holds up, Docs match ## Who gets in - Agents on a server: Turned away when they send the sign-up form. - Signed agents: The sign-up page opens. The check on the form still applies. - Agents in a person's browser: Not measured yet. Sign-up page checked 16 Oct 2026. Signed agents: the ones Cloudflare verifies. ## Ways in - Email and code: Stopped by a CAPTCHA - Email link: Not tried: the same as another way - Continue with Google: Not tried: no account yet - Sign-in for apps (OAuth, MCP): Not reached - Company single sign-on: Not tried: needs a person's account - Added by an admin: Not tried: needs a person's account ## The docs 163 of 164 pages read. Complete. - A getting-started page - An auth page - Errors listed with their codes - Code examples on some pages - Newest page updated 15 Oct 2026 - A page for 10 of 10 core tasks ## Checkpoints - **Docs**: Headless: llms.txt and every docs page as .md (text/markdown); GraphQL getting started, OAuth, rate limits, MCP setup and the full SDL schema are public. - **Sign up**: Needs a human: Continue with email showed a visible Cloudflare Turnstile "Verify you are human" after the email was entered; we do not solve it. - **Verify**: Not reached: Not reached: no login mail was sent because the Turnstile stops the form first. - **Key**: Not reached: Not reached. API keys are made only at Settings > Account > Security & Access in the web app; the public schema has no key mutation. - **First call**: Not reached: Not reached: the GraphQL API and the MCP server need a key or OAuth token from an account. - **First action**: Not reached: Not reached: no account. - **Pay**: Not reached: No agent rail: no 402 on any host, not on mpp.dev, Stripe Projects or the x402 Bazaar; we paid nothing. Plans are changed at Settings > Administration > Billing in the app (docs/billing-and-plans.md); Basic is $10 per user/month billed yearly. - **Cancel**: Not reached: Nothing started. Docs: admins change or cancel at Settings > Administration > Billing (web UI); the change takes effect at the end of the period. - **Delete**: Not reached: No account was created, so nothing was left. The public schema documents organizationDeleteChallenge + organizationDelete(deletionCode) for deleting a workspace by API. ## Does Linear have an MCP server, and can an agent connect to it? Yes. Linear has an official MCP server. The server is hosted. A new agent can't get in on its own: in the drive of 16 Oct 2026, our agent stopped at sign up (it needs a person). Through the MCP server, 0 of our agent's 6 attempts worked. ## How does an AI agent get a Linear API key? Not reached: in the drive of 16 Oct 2026, sign-up stopped our agent first (it needs a person). Not reached. API keys are made only at Settings > Account > Security & Access in the web app; the public schema has no key mutation. ## Paying the agent way Payment not reached. The checkout: The checkout wasn't reached: Basic, $10 a month; Checkout: a checkout; No CAPTCHA at checkout. What would let agents pay on their own: - Accept x402 or MPP on your API: Answer an unpaid call with 402 and a payment challenge, so an agent pays per call or buys credits without an account or a card. - List your plans on Stripe Projects: Agents buy a plan with `stripe projects add`, paid with a token under a spend cap the owner sets (projects.dev). Ways to pay checked 16 Oct 2026. ## What an agent can do - Read every docs page as Markdown (.md URL or Accept: text/markdown) - Read the full public GraphQL schema without an account ## What it cannot do - Create an account: A visible Cloudflare Turnstile appears after the email is submitted on the sign-up form - Get an API key or call the API, MCP server or any capability: Both need an account; keys are made only in the web settings - Pay for a plan as an agent: No x402/MPP or billing API; upgrades are in the app's billing page ## Tips for the owner 1. Let verified signed agents skip the sign-up check 2. Offer API key creation by API 3. Serve MCP discovery and protected resource metadata 4. Support MCP (the 28 Jul 2026 spec) and CIMD 5.
