// tools this server exposes26 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

sendcraft_send_email

Send a single transactional email immediately. Use this for order confirmations, password resets, notifications, and any one-off email triggered by a user action.

sendcraft_schedule_email

Schedule an email for future delivery. Use this for reminders, follow-ups, drip messages, or any email that should go out at a specific time.

sendcraft_cancel_scheduled_email

Cancel a scheduled email before it is sent. Use when a user cancels an order, changes their preferences, or the scheduled action is no longer needed.

sendcraft_batch_send

Send up to 100 distinct emails in a single API call. Each email can have a different recipient, subject, and body. More efficient than calling send_email 100 times.

sendcraft_get_email

Retrieve details and delivery status for a single email by its ID. Use to check whether a specific email was delivered, opened, or bounced.

sendcraft_list_emails

List recently sent emails with delivery status. Use to audit what was sent, find a specific email, or monitor deliverability.

sendcraft_get_stats

Get aggregate email statistics: total sent, open rate, click rate, bounce rate, and complaint rate. Use to understand overall sending health.

sendcraft_list_campaigns

List email marketing campaigns with their status and performance metrics.

sendcraft_create_campaign

Create a new email marketing campaign. After creating, call sendcraft_send_campaign to send it.

sendcraft_send_campaign

Send an existing draft campaign immediately, or schedule it for a future time.

sendcraft_get_campaign_analytics

Get detailed analytics for a specific campaign: opens, clicks, bounces, unsubscribes, and click heatmap data.

sendcraft_list_subscribers

List subscribers/contacts with their status and tags.

sendcraft_add_subscriber

Add a new subscriber/contact to a list. If the list has double opt-in enabled, a confirmation email is sent automatically.

sendcraft_unsubscribe

Unsubscribe a contact from all marketing emails. Use when processing manual unsubscribe requests or GDPR deletion requests.

sendcraft_list_templates

List saved email templates. Templates can be reused across campaigns and transactional emails.

sendcraft_create_template

Save an email template for reuse. Templates support {{variable}} placeholders for personalization.

sendcraft_list_domains

List sender domains and their DNS verification status (SPF, DKIM, DMARC). Emails from unverified domains may land in spam.

sendcraft_add_domain

Add a new sender domain and get the DNS records (SPF, DKIM, DMARC, BIMI) to configure at your DNS provider.

sendcraft_verify_domain

Check if the DNS records for a domain are correctly configured. Call this after updating DNS records to confirm verification.

sendcraft_analyze_dmarc

Analyze the DMARC record for a verified domain. Returns a score (0-100), policy strength, and specific issues to fix.

sendcraft_list_segments

List subscriber segments. Segments are dynamic groups of subscribers matching specific criteria (country, tags, activity, etc.).

sendcraft_get_warmup_status

Check the IP warmup status for the self-hosted SMTP server. Returns current day, daily send limit, emails sent today, and remaining quota. Important to check before sending large batches.

sendcraft_list_topics

List email topics/categories. Topics let subscribers choose which types of emails they receive (e.g. product-updates, weekly-digest, promotions).

sendcraft_get_subscriber_topics

Get the topic preferences for a specific subscriber — which topics they are opted in or out of.

sendcraft_get_send_time

Get AI-powered send-time optimisation. Returns the best day of week and hour of day (UTC) to send campaigns for maximum open rate, based on your subscribers' historical open patterns.

sendcraft_list_api_keys

List API keys for the account. Returns masked keys (never the full value), permissions scope, and last-used date.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

26/26 tools missing one or more hints — sendcraft_send_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sendcraft_schedule_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sendcraft_cancel_scheduled_email (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +23 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tests exist

Add tests that exercise each declared tool.

Production dependencies are patched

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
