Toolcape connects a company’s existing AI to its systems through one MCP entry point, with account connections, group and individual permissions, and audit logs. This documentation describes a product prototype; it is not evidence that a live server or account is connected.
Postmark Account: The delivery service for automated emails from applications.
API connection · AI uses Toolcape through MCP
Administrator-managed shared credential. Its rights may differ from the member’s own account.
- Read: Inspect supported server and delivery information
- Create: Use explicitly approved sending operations
- Change: Change supported email-service settings
A shared credential represents the service, not each employee’s inbox. Have the email administrator confirm credential type and available operations.
1. IT configures the provider app, API and requested scopes.
2. Administrator-managed shared credential. Its rights may differ from the member’s own account.
3. Make the service available in Toolcape. Set Everyone, group and individual rules for the actions actually needed. Adding a service does not grant access.
4. Connect the approved AI client to the actual Toolcape MCP address and sign in. Start with a harmless read-only task and check the audit log.
For personal delegated access, the provider account, approved app scopes and Toolcape rules must all permit the action. Shared accounts and application permissions may have other limits. Toolcape combines Everyone and group grants; a personal exception replaces inherited access for that service. Reading can disclose confidential information. Sharing, sending and deletion need separate consideration.
First discover which tools the connected Toolcape server actually exposes. If it offers search → describe → execute, find the relevant operation, inspect its input schema and permissions, then call it with validated inputs. Tool names vary by server; do not invent names, arguments, URLs or successful outcomes. Without connected tools, give setup guidance instead of claiming to perform actions.
