What Cast AI (BYOK) is for

Cast AI (BYOK) lets an AI assistant read your own Cast AI data through the Cast AI API with a key you supply (Cast AI API key (read-only access is enough)). Read-only: 10 tools (list_clusters, get_cluster, list_nodes, get_cluster_summary, list_clusters_summary, get_daily_cost_report, get_clusters_efficiency, list_node_templates, list_audit_events, get_platform_usage_report). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.cast.ai. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Cast AI. Cast AI and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which Kubernetes clusters are connected to Cast AI?"
• "What is the status of my Cast AI cluster prod-eks?"
• "Which nodes does my Cast AI cluster run and how many are spot?"
• "What does my Cast AI cluster cost per hour right now?"
• "What do all my Cast AI clusters cost per hour?"
• "How did my Kubernetes cost develop over the last week in Cast AI?"

What it does

• list_clusters: List the Kubernetes clusters connected to your organization with cloud provider, region, status and agent status.
• get_cluster: Get one cluster: provider, region, status, agent status, creation time and tags.
• list_nodes: List the nodes of a cluster with instance type, lifecycle (spot flag), zone, state, CPU and memory capacity and Kubernetes version.
• get_cluster_summary: Get a cluster's current resource and cost summary: node counts, provisioned and requested CPU and RAM, hourly cost on-demand and spot, pod counts.
• list_clusters_summary: Get the current resource and cost summary of every cluster in the organization.
• get_daily_cost_report: Get hourly cost over a time range for every cluster: cost per hour for on-demand, spot and spot fallback nodes.
• get_clusters_efficiency: Get the efficiency summary per cluster for a time range: wasted CPU, RAM and storage and over-provisioning percent.
• list_node_templates: List a cluster's node templates with their name and constraints such as CPU and memory range, spot and on-demand use.
• list_audit_events: List audit events (who did what to which resource, with severity and time) for a date range.
• get_platform_usage_report: Get this month's platform usage by feature with units, credits total, used and remaining, and subscription periods.

BYOK key

You bring your own Cast AI Cast AI API key (read-only access is enough) (https://console.cast.ai/api/api-access). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.cast.ai over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Cast AI (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Cast AI (BYOK) is. Cast AI (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Cast AI data: Read your Cast AI connected Kubernetes clusters, nodes, cost and efficiency reports, node templates, audit events and platform usage with your own API key (US region). You bring your own Cast AI Cast AI API key (read-only access is enough); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Cast AI call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.cast.ai, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Cast AI rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Cast AI receives. The request we make on your behalf, including the key and the arguments, under Cast AI's own terms and privacy policy. Cast AI acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Cast AI gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Cast AI data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Cast AI (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Cast AI at any time to end all access.

Children. Cast AI (BYOK) is a general-audience service operated by the adult using the assistant, under Cast AI's own age rules.

Changes. We will post changes here with a new effective date.
