How do I find my Instance ZUID?

You can list all your accessible instances using the `list_zesty_instances` tool, or find it in your Zesty.io URL (it starts with `8-`).

Can I see all content items for a particular model?

Yes, use the `list_content_items` tool with the unique ZUID of the model (starts with `6-`) to retrieve all associated entries.

Is it possible to update content via the agent?

Absolutely. Use the `update_content_item` tool by providing the Model ZUID, the Item ZUID, and a JSON object containing the fields you wish to modify.

About Zesty.io MCP Server

Connect your Zesty.io account to any AI agent to streamline your headless CMS operations. This MCP server enables your agent to interact with instances, content models, and data entries (items) directly from natural language.

LangChain's ecosystem of 500+ components combines seamlessly with Zesty.io through native MCP adapters. Connect 8 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

What you can do

Instance Oversight — List all Zesty.io instances associated with your account and retrieve their metadata
Schema Management — List content models to understand your data structures and identify Model ZUIDs
Content Operations — List, retrieve, create, and update content items within specific models
Technical Auditing — Access instance settings and technical metadata for any of your properties
Workflow Automation — Delete content items and maintain your CMS hierarchy via natural language commands

The Zesty.io MCP Server exposes 8 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
