## MCP tool

`manitu_message_send`

### Description for the model

Sends a message to manitu in the customer's name - to a department from manitu_message_recipient_list (support, accounting, ...). manitu answers by e-mail to the address of this access, not in this chat. Before writing, call manitu_message_guide_get and follow it. Write it as the customer would: clear, polite, with what manitu needs (which domain or server, what happened, what is wanted) - but only what the customer told you; never add passwords or other secrets. Before sending, show the customer recipient, subject and text and wait for an explicit yes. The customer always gets a copy by e-mail; manitu sees that the message was written with an AI assistant. A termination of a contract or a legal matter cannot be sent this way (refused: termination_not_by_message, legal_not_by_message) - tell the customer to use his own way of contact for it, do not rephrase it to get around this. At most 5 messages an hour (limit_reached) - one message with everything is better than several.

### Arguments

- `recipient` (string, required) - The department - from manitu_message_recipient_list. (one of `"info"`, `"support"`, `"accounting"`)
- `subject` (string, required) - (minLength `1`; maxLength `200`)
- `body` (string, required) - The message, plain text. (minLength `1`; maxLength `2048`)
- `cc_to_customer` (boolean) - Send the customer a copy. Default false; over MCP a copy always goes.
- `attachment_list` (array of object) - Files, 10 MB in all. (maxItems `3`)
  - `attachment_list[].name` (string, required) - The file name, e.g. "screenshot.png". (minLength `1`; maxLength `200`; pattern `"^[^/\\\\\\x00-\\x1F]+$"`)
  - `attachment_list[].data` (string, required) - The content: "base64:" followed by the file in base64. (pattern `"^base64:"`)
