# Plans and limits

> Load this page when: you need the limits of a plan, or you need to handle a limit error from the CLI, the REST API or MCP

## For agents

- Read limits from the table. Never quote a number from memory.
- Stop and tell the user when a limit is reached. Do not retry.
- Reads reset on the first day of each month, UTC.

The table shows what the current Personal (free) and Professional plans allow. Older accounts can have different limits.

| Limit | Personal | Professional |
| --- | --- | --- |
| Books in your library | 5 | 200 |
| Reads per month | 100 | Unlimited |
| Manuscripts | 1 | Unlimited |
| Largest upload | 100 MB | 500 MB |
| Publish to the marketplace | No | Yes |

Plans and prices are on [billing](https://heytrove.ai/billing).

## When a limit is reached

A limit never deletes anything. The call that went over is refused, and the response says which limit it was.

| Limit | Where the error is explained |
| --- | --- |
| Books in your library | [REST errors](https://docs.heytrove.ai/reference/api.md#errors), code `PLAN_LIMIT_EXCEEDED` |
| Monthly reads | [REST errors](https://docs.heytrove.ai/reference/api.md#errors), code `READ_LIMIT_EXCEEDED` |
| A locked book | [REST errors](https://docs.heytrove.ai/reference/api.md#errors), code `ITEM_LOCKED` |
| Any limit over MCP | [MCP limits](https://docs.heytrove.ai/reference/mcp.md#limits) |

Both the book limit and the read limit are per account. Reads reset on the first day of each month, UTC.
