The Missive MCP connector for ChatGPT currently trims quoted email content when retrieving conversations. This can cause some incoming messages—particularly replies generated by platforms such as Salesforce—to appear to ChatGPT with an empty body, even though the complete message is visible in Missive.

Missive's REST API already provides a solution through GET /v1/messages/:id, which returns the full, untrimmed message body. However, that functionality is not currently exposed through the MCP connector, so ChatGPT cannot access it.

It would be very helpful to add an MCP tool for retrieving an individual message by ID with its complete body, similar to the REST API endpoint.

This would allow ChatGPT to fall back to the full-message endpoint whenever a message returned through a conversation is empty or incomplete. It would significantly improve ChatGPT's ability to review complete email threads, understand incoming replies, summarize conversations, and draft accurate responses without requiring the user to manually open or screenshot missing messages.
