  What this check looks for
Description, as the server wrote it
Reports the credit balance, tier, rate limits, and upgrade options for the API key on this connection, or the free-tier allowance and the key URL for an anonymous caller. Free — this call does not consume a credit. Also mints or returns a referral code; `referral_code` on later calls keeps the same referral identity.

formation.checkoutCreates the founder's formation order and a USDC (Solana) payment request — no API key, no Corpus sign-in.No findings
Why it is in this group
- The name "formation.checkout" says "checkout": a word for a change.
Description, as the server wrote it
Creates the founder's formation order and a USDC (Solana) payment request — no API key, no Corpus sign-in. Payment is USDC on Solana ONLY. The first call takes the complete draft, the founder's contactEmail, an idempotencyKey (the same order is returned on retry), and consent { version, registeredAgentAcknowledgements: true }, which records that the founder accepted the registered-agent acknowledgements. A queue-lane order first returns a submission promise, accepted with a second call { orderId, trackingToken, acceptPromise: { termDays } }. The payment response includes a payPageUrl: an ordinary https link to a Corpus page with a QR code to scan with a phone camera, a button that opens a Solana wallet, and the address and exact amount for a manual send. The founder pays the exact amount from a self-custody wallet (never an exchange withdrawal; refunds go only to the sending wallet) and must click the confirmation link Corpus emails within 48 hours, or the order is refunded. Nothing is filed before that confirmation, and then Corpus's human review, unless the founder chose to skip review on an expedited order (offered only where formation.requirements shows a SKIP REVIEW line). The tax-ID add-on is not sold here. Free; does not consume credits.

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
