Capabilities

tools

Known tools 28

setup_infrastructure

Provision sending infrastructure: buy branded lookalike domains, create mailboxes, start warmup.

Potential side effects

infrastructure_status

Warmup + provisioning progress per mailbox.

Inferred read-only

launch_campaign

Create and activate a campaign on a lead list.

Potential side effects

campaign_results

Outcome counts for ONE campaign.

Inferred read-only

metrics

Account-wide outcome totals across ALL campaigns: { sent, reply, bounce, complaint, unsubscribe, failed, soft_bounce } — same shape as campaign_results but summed tenant-wide (bounce = hard only, opens not tracked).

Inferred read-only

inbox

Unified reply inbox across mailboxes.

Inferred read-only

thread

Full message history for ONE thread.

Potential side effects

reply

Send a reply on an existing thread, from the mailbox that sent it.

Potential side effects

mark

Set a thread's READ-STATE for inbox triage.

Inferred read-only

pause

Pause ONE campaign: its status → 'paused', so the tick schedules no further steps (already-sent mail is unaffected; there is no resume tool).

Inferred read-only

pause_all

Pause EVERY active campaign for the tenant at once (each active status → 'paused'; the tick then schedules no further sends).

Inferred read-only

account

Account overview: brand, plan, status, billingState, activationState, resource counts, usageCents, quota, deliverability (loop state: paused/throttled mailboxes, burning domains, auto-replacements, recentActions[]), and teardown (reclaim summary once canceled, else null).

Inferred read-only

remove_mailboxes

Downgrade: release your N NEWEST live mailboxes now and lower the billed quantity.

Inferred read-only

get_dashboard

Read saved dashboard views.

Inferred read-only

configure_dashboard

Write a saved dashboard view.

Potential side effects

label_thread

Set or clear a triage LABEL on an inbox thread — the same chip the dashboard shows.

Inferred read-only

list_campaigns

List every campaign at once: [{ campaignId, name, status, counts{sent,reply,bounce,complaint,unsubscribe,failed,soft_bounce} }], newest first — no per-campaign lookup needed.

Inferred read-only

activity

Unified activity feed: campaign events (sent/reply/bounce/.

Inferred read-only

get_webhooks

List your outbound webhook subscriptions, or (with id) one subscription plus its recent delivery + attempt log.

Inferred read-only

configure_webhook

Manage an outbound webhook subscription.

Inferred read-only

get_byo_domains

List your BYO (bring-your-own) domains, or (with id) one domain's full intake detail.

Inferred read-only

configure_byo_domain

Inferred read-only

suppress_lead

Permanently suppress an email address tenant-wide (every current and future campaign) — the manual/free-text 'stop emailing me' path for opt-outs the strict typed-unsubscribe matcher misses.

Potential side effects

update_lead

Record what you learned about a contact (their reply, your triage) as a durable, contact-level disposition — keyed by email, visible across every campaign that lists them.

Potential side effects

list_leads

List/export leads with their contact-level disposition, cursor-paginated.

Inferred read-only

list_messages

List this tenant's system + operator messages (a retryable setup step, a credential going live, an operator notice), cursor-paginated.

Inferred read-only

ack_message

Acknowledge a message by id (from list_messages or infrastructure_status's messages[]) — sets it read so it stops surfacing as unacked.

Potential side effects

contact_operator

Reach a human operator — for anything list_messages/infrastructure_status can't answer (a stuck vendor issue, a billing question, an account-level ask).

Inferred read-only

CONNECT WITH APPROVAL

Client installation

Review this server and its permissions before adding it. Secret placeholders must be set locally.
