Gmail MCP server does not include display name in From header

Description

When sending emails via the Gmail MCP server integration ("claude.ai Gmail"), the From header does not include the sender's display name. Recipients see the raw email address username (e.g., "agenticaccelerator") instead of the properly configured display name (e.g., "Agentic Accelerator").

Steps to Reproduce

1. Configure a Gmail account with a display name containing spaces/capitalization (e.g., "Agentic Accelerator")
2. Verify the name is correct in both:

• Google Account → Personal Info → Name
• Gmail → Settings → Accounts and Import → "Send mail as"

1. Use the send_email tool from the Gmail MCP server to send an email
2. Check the received email — the sender shows as the email username (e.g., "agenticaccelerator") rather than the configured display name ("Agentic Accelerator")

Expected Behavior

The From header should include the display name from the Gmail account's "Send mail as" setting, e.g.:

From: Agentic Accelerator <agenticaccelerator@gmail.com>

Actual Behavior

The From header appears to omit the display name, so recipients see the email address username as the sender name:

From: agenticaccelerator@gmail.com
