## Tools
- cardclan_create_integration_config(card_id: string, workspace_id: string) — Create a persistent CardClan integration configuration linking a card to its workspace. The connected user's ID is resolved automatically.
- cardclan_generate_card_url(card_id: string, recipients: object[], integration_id: string) — Generate a personalized CardClan viewing URL without sending an email. This may create recipient-specific CardClan state but does not deliver a message.
- cardclan_get_card_details(card_id: string) — Get a CardClan card's title, merge-tag requirements, and owning workspace details by card ID.
- cardclan_get_integration_config(card_id?: string, integration_id?: string) — Get a CardClan integration configuration by either integration ID or card ID.
- cardclan_list_cards(workspace_id: string) — List cards in a CardClan workspace, including card IDs needed for details, integration configuration, personalized links, and sending.
- cardclan_list_email_accounts() — List configured CardClan sender accounts that can be selected when sending a card.
- cardclan_list_workflow_cards() — List cards with active CardClan integration workflows and return their integration, card, and workspace IDs.
- cardclan_list_workspaces() — List CardClan workspaces accessible to the connected account, including the workspace IDs needed to find cards and create integration configurations.
- cardclan_send_card(card_id: string, recipients: object[], confirm_send: boolean, integration_id: string, email_account_id?: string) — Immediately personalize and send a CardClan card by email to one or more recipients. This externally side-effecting operation is irreversible; use GENERATE_CARD_URL when delivery is not intended.
