search_emails and get_thread deliberately omit bodies; use this tool to open a specific hit.
Parameters
string
required
The message id, as returned by
search_emails or get_thread.Example
Call
Result
Cc: appears only when the message has CC recipients; Tags: only when the message carries an email type or sub-agent label. A message without a text body returns (no text body) in place of the body.
The attachments section lists every file part with its filename, media type, human-readable size, and the blobId handle that download_attachment takes. Parts marked inline are images referenced by the HTML body (logos, signatures, tracking pixels) rather than genuine documents. Messages without attachments omit the section entirely — and the bytes themselves are never returned by this tool.
Bodies are capped at 100,000 bytes; longer bodies are truncated at that limit.
Errors
Email not found: <id>— no message with that id in the caller’s mailbox.
