Which MCP Server Should You Choose?
Choose Sendraven MCP Server when:
You need dedicated capabilities in the Communication domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Send a transactional email, immediately or scheduled. Use scheduled_at with a relative phrase like 'in 3 days' or an ISO timestamp. The From domain must already be verified.
list_emails
List recent messages with their delivery status. Filter by status (queued, scheduled, sent, delivered, bounced, complained, rejected) or recipient.
get_email
Fetch one message with its full event timeline (send, delivery, bounce, complaint, open, click). This is the tool to reach for when asked why an email didn't arrive.
cancel_scheduled_email
Cancel a scheduled email before it sends. Only works while status is 'scheduled'.
list_sending_domains
List sending domains with their verification status and the DNS records each one needs. Each record shows what is currently published, so this diagnoses a stuck verification.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Sendraven MCP Server is categorized under Communication and uses a local stdio subprocess. In contrast, Agent Email belongs to Communication using local stdio subprocess. Select Sendraven MCP Server when you need capabilities focused on communication and Agent Email when you require tools for communication.
Register a sending domain and get back the DNS records to publish. Give the domain you send from — mail.<domain> and news.<domain> are provisioned beneath it and the right one is chosen per message, so a marketing complaint spike can never affect password reset delivery. Pass risk_class only to pro…
verify_sending_domain
Re-check a domain's DNS records now instead of waiting for the background monitor.
list_suppressions
List addresses we refuse to mail and why (hard_bounce, complaint, unsubscribe, manual). Check here first when someone reports not receiving email.
add_suppression
Stop sending to an address. Scope 'marketing' leaves transactional mail working.
remove_suppression
Remove a suppression so the address can be mailed again. Be careful with hard bounces — the address was rejected by the receiving server, and re-sending raises the bounce rate that AWS enforces on.
create_broadcast
Create a campaign as a draft. Nothing is sent: follow with preview_broadcast, then send_broadcast. identity_id must be a marketing sending domain (see list_sending_domains; risk_class 'marketing'). To A/B test, pass 2 to 10 'variants' that differ in subject, from_name or send_at, and optionally 'ab…
get_broadcast
One campaign, with a 'progress' object while it is sending, paused or testing: how many addresses are still pending, sent, failed, or skipped because the person opted out after the campaign started. This is how you tell a paused campaign that is still making progress from one waiting on quota. An A…
