Inbox Zero MCP

Connect to the Inbox Zero MCP server configured in mcp.json (OAuth, Streamable HTTP). Hosted URL: https://www.getinboxzero.com/mcp.

Tools

• list_email_accounts first when the user has more than one inbox. Pass emailAccountId or emailAddress on later calls.
• search_inbox for message metadata and snippets. Do not treat snippets as full bodies.
• read_thread for truncated plain-text bodies after you have a threadId.
• create_draft to save a mailbox draft. This does not send. Never invent a send tool.
• Rule tools (list_rules, get_rule, create_rule, update_rule, delete_rule) and stats tools manage automation and analytics, not mail delivery.

Safety

• Do not send email. Drafts stay in the mailbox until the user sends them.
• Do not dump full thread bodies into follow-up tool arguments; summarize.
• Disconnect and MCP access are controlled in Inbox Zero Settings → Account → MCP, not by this skill.
