One MCP for the card

Connect the agent that runs the company.

Claude, Grok, ChatGPT, and Cursor all use the same address. You sign in once. The agent can read the company, the grade, and the card. Anything that changes the company comes back to you as a confirmation link.

Once it is connected, if the agent stops before sharing, paste this: Use the Antal connector. Call get_next_steps, then share everything you know about my business with submit_session_context: revenue, customers, contracts, team, and funding, with short quotes as evidence.

What the agent is allowed to do

Read the company, the people, the grade memo, the card last four, and the bank status.
Send a session packet from the conversation it already has open. Unconfirmed packets do not change the grade.
Ask for a card. The card is issued only after you confirm, and only when the file clears.
Ask Link for a test purchase. A confirmed policy can approve a small amount. The full card number never comes back to the agent.

What stays with you

You sign in with the email on the company. OAuth uses a code and PKCE. The redirect has to be https, a localhost address, or the agent's own app link.
Social Security numbers and the full card number are write-only. The agent sees a last four, never the number.
Disconnecting an agent drops its excerpts. A revoked packet no longer counts.
Link is the wallet you control. Test mode does not charge a real card. A single spend request stops at $500, and your policy can be tighter.
Identity from Link is a suggestion. It does not replace the company check.
