FAQ
Common questions about AgentMail and Cursor.
- Does AgentMail work with Cursor via MCP?
- Yes. Add the AgentMail MCP server with one command and every Cursor agent you build gets access to email tools.
- What operations does the MCP server expose?
- Inbox creation and deletion, sending messages, listing and reading messages, replying to threads, managing attachments, and setting up webhooks.
- Can I also use the SDK alongside MCP?
- Yes. MCP gives your agent conversational access to email. The SDK gives you programmatic control in code. They use the same API and the same inboxes.
- How many inboxes can I create?
- Free: 3. Developer ($20/mo): 10. Startup ($200/mo): 150. Enterprise: unlimited.
- Can agents receive email too?
- Yes. Every AgentMail inbox is a real email address. Incoming messages are available instantly via the API, MCP, or webhooks.
- Why not just use the Gmail API or SendGrid?
- Gmail API requires OAuth and was built for human accounts, not programmatic agent use. SendGrid handles sending only - no receiving, no threading, no reply parsing. AgentMail gives your Cursor agent a dedicated inbox it can create on demand, send from, receive on, and read - with full thread context and no credential sharing.
