Description from the maker (original English)
Deskhand CRM for AI agents: key per agent, undo a run, email drafts. Start with one POST.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
search_contactsFind contacts by text (name, email, title), status, source, company or a custom field. Returns up to `limit` contacts and a next_cursor. Requires the read_crm scope.
upsert_contactCreate a contact, or update the one that already has this email (matched case-insensitively). Custom `fields` and `tags` are merged into what is stored. A company is created or reused from company_domain or company_name. Requires the write_crm scope.
update_contactChange fields of an existing contact, found by id or email. Custom `fields` are merged with the existing ones. Requires the write_crm scope.
create_dealOpen a deal, optionally linked to a contact (by id or email) and a company. Stages: lead, contacted, qualified, proposal, won, lost. The deal takes its contact's company unless company_id is given. Unknown arguments are rejected with unknown_field. Requires the write_crm scope.
move_dealSet a deal's stage (lead, contacted, qualified, proposal, won, lost). Requires the write_crm scope.
add_noteAttach a note to a contact (by id or email) or to a deal. Requires the write_crm scope.
create_taskCreate a follow-up task or reminder with an optional due date, on a contact or a deal. Requires the manage_tasks scope.
list_due_tasksWhat is due now: overdue and due-today tasks first, then the next 7 days. Tasks on contacts who replied, unsubscribed or bounced are flagged follow_up_blocked: do not chase those. Requires manage_tasks or read_crm.
draft_emailDraft one email to a contact. Drafts are auto-approved by default (the operator can switch approval on for the workspace or for you; then the draft waits in their Approvals inbox). Approved mail that cannot be sent to the recipient yet waits in the operator's To send list and the
list_email_statusStatus of this agent's emails: pending_approval (only when approval is on), approved (with a note when it waits in the manual To send hand-off), rejected (with reject_reason to learn from), sent, failed, cancelled. Each email carries warnings (open_draft_exists, emailed_N_days_ag
list_repliesReplies captured from contacts, newest first. Requires the read_crm scope.
get_threadSent mail and replies for one contact in time order. Requires the read_crm scope.
mark_repliedRecord that a contact replied (optionally with the reply text). Sets the contact to replied, cancels their pending drafts and open follow-up tasks, and stops further drafts to them. Requires the write_crm scope.
get_policyWhat the operator allows this agent: the workspace approval setting and, in plain words, what happens to your CRM writes and email drafts (apply or auto-approve at once, or wait for approval), this agent's mode (direct or propose), daily send caps and how many were used today, bl
create_campaignCreate a campaign: an ordered sequence of email, wait and task steps run per contact, with follow-ups, stop rules (reply, bounce, unsubscribe and deal stage change stop a contact's sequence), a send window, caps and A/B variants. Pass steps inline, and optionally `enroll` to sele
update_campaignChange a campaign's settings and/or replace its ordered steps. Editing the steps of a running campaign needs the operator's approval when approval is on. Requires the manage_campaigns scope.
get_campaignOne campaign with its steps, status, delivery mode (dry run or live) and counters.
list_campaignsCampaigns in this workspace with status, delivery mode and enrolled/sent/replied counters. Archived ones are hidden unless status=archived.
enroll_contactsEnroll contacts by ids, tag, source/list, status, text or custom fields. Suppressed, replied, unsubscribed, bounced, address-less and blocked-domain contacts are skipped with a reason, and a contact in another running campaign is skipped (or moved with on_conflict=move). dry_run=
simulate_campaignWhat would go out over the next N days: per contact and step, the send time (UTC and local), the fully rendered subject and body, and the status (will_send, skipped_missing_variable, skipped_condition, blocked_by_cap, task_created), plus problems and launch_blockers. Nothing is w
launch_campaignStart a draft campaign. Refused with launch_blockers (postal address, sender name, an email step, enrolled contacts, a verified identity) until they are fixed. With approval on, it returns 202 and waits for the operator to approve the launch once. Requires the manage_campaigns sc
pause_campaignFreeze a running campaign. Nothing is lost: resuming shifts every pending step by the length of the pause. Requires the manage_campaigns scope.
resume_campaignResume a paused campaign. Requires the manage_campaigns scope.
stop_enrollmentStop a single enrollment (reason manual). Requires the manage_campaigns scope.
campaign_reportCounts per campaign, per step and per variant: enrolled, active, completed, stopped (by reason), sent, sent_dry (dry-run records, nothing delivered), skipped (by reason), replied, bounced, unsubscribed, meetings, deals_created. Rates say which count they divide by.
get_outboxFor a campaign that sends through your own sender (relay identity): the operator-approved messages you may send now, each with its exact text, recipient, step and evidence link, plus batch_id and batch_hash. Send the text byte for byte, then call report_send for every message. 40
report_sendReport one outbox message: sent (final: the person moves to the next step; reporting sent twice is fine, a different second report is 409 already_reported), refused_cap, refused_unsigned or failed_transient (the message stays in To send and gives its cap unit back), refused_suppr
list_sending_identitiesThe identities a campaign can send through: the built-in dry_run identity and any the operator connected (their keys are never shown), with their delivery state.
add_suppressionNever email this address or domain again, in any campaign. Open enrollments of matching contacts stop. Removing an entry needs the operator. Requires the manage_campaigns scope.
list_suppressionsAddresses and domains that are never emailed.
