Security & Code Integrity Audit

Every tool in the Close MCP Server is continuously audited by the Vinkius Security Engine. We guarantee zero-trust payload isolation, strict data boundaries, and deterministic execution for enterprise-grade AI agents.

How Vinkius protects your data

Can I audit what my AI agents are doing with this integration?

Yes, Vinkius provides an immutable, HMAC-chained audit log. Every tool execution, payload, and response is tracked in real-time on your dashboard, giving you complete visibility into your agent's actions.

How does the API authentication work with Close?

Close uses HTTP Basic Authentication. Your API Key is sent as the username with an empty password. Navigate to Settings > Developer > API Keys in your Close dashboard to generate a new key. The key is encrypted at rest and injected securely at runtime.

How does the AI access my passwords and credentials?

It simply doesn't. On Vinkius, your passwords, API keys, and login details are kept in a secure vault. The AI (like ChatGPT or Claude) merely "asks" Vinkius to perform the task. Vinkius opens the door, does the work, and hands the result back to the AI. Your credentials are never seen, read, or learned by the artificial intelligence.

Does the AI train on my tools or API data?

No. Vinkius enforces a strict Zero-Retention policy. Your data simply passes through our secure servers to complete the requested action and is instantly forgotten. Nothing you do here is ever stored, logged, or used to train any artificial intelligence.

How Chatbots Interact with Close

The Close integration provides comprehensive execution endpoints, allowing AI models to orchestrate tasks reliably.

Execute lead management Commands with AI

Connect Close to your AI agents (Claude, ChatGPT, Cursor) to manage lead management operations. The MCP server processes the underlying API requests and schema formatting for the communication messaging domain.

Next-Gen pipeline tracking Automation

Add pipeline tracking functionality to your custom chatbots. The Close MCP handles the payload formatting required for ChatGPT and Claude to interface with communication messaging endpoints.
