The MCP Server is available on all Box plans.
API calls are free only if both of the following conditions are met:
- You are using an app published in the Box Integrations Center, and
- You log in with your own Box account (OAuth).
This is the standard end-user use case (e.g., ChatGPT, Claude, Figma, etc.).
When API calls are charged
API calls are charged in all other cases, for example:
- Non-published Box Platform apps
- Custom integrations or automations
- Use of additional integration credentials from the Box MCP Server
- Service account or scaled/shared workflows
| Case | Charged? |
|---|
| Published app + your own Box login | No |
| Other use cases | Yes |
| AI, DocGen, Sign | Yes, based on your plan usage |
How API calls are charged
If your use case falls into the charged category above, API usage is metered as follows:
| Action | Cost |
|---|
| Any tool invocation | 1 API call |
| AI tool invocation | 1 API call + AI Units (based on model tier and document length) |
| Session initialization (once per session) | 1 API call |
| List tools (once per session) | 1 API call |
| DocGen tool invocation | 1 API call + cost per document generated beyond included allowance |
| Sign request | 1 API call + Sign usage (per request; plan limits apply) |
Box AI, DocGen, and Sign are features included in specific Box plans and are subject to plan availability and limits. AI tools require a Box AI-enabled plan, DocGen and Sign depend on plan availability.
