  • Not measured
    Stable tool list

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

commsharbor_audit

List tenant audit events. Audit records are never rewritten and never carry recipient PII.

Discovered
commsharbor_brazil_email_report

Read the monthly Brazil email security report: how many domains of city halls, state and federal government, banks and listed companies reject fake email (DMARC p=reject) and how they end SPF. Totals only, public DNS. Free, no account. Public DNS only, read once a month. The sample is built from Brazil's open company registry (Receita Federal, the email of each active head office) and the CVM register of listed companies. Only totals: no domain is listed. A share is `count / (com_mx - dmarc.nao_lido)`; domains without MX are left out. Only the DMARC policy classifies; SPF is counted but does not change the class. `percent` rounds each group to 100 by the largest remainder, the same rule as the page.

Discovered
commsharbor_context

Resolve the active organization identity. Read this before a write when you are not certain which tenant is active. Guessing is how data lands in the wrong organization. An organization API key answers `kind: api_key` with its scopes.

Discovered
commsharbor_email_alias_create

Discovered
commsharbor_email_google_catalog

Read authorized Google metadata. This does not prove DNS ownership. Requires the owner's account session; an organization key cannot authorize Google access. Requires an account session in this organization. Reads site metadata only. Google access and refresh tokens remain encrypted on the server. This does not change DNS, buy a subscription or grant another product access to Google data.

Discovered
commsharbor_email_google_connect

Discovered
commsharbor_email_security_check

Check whether someone can send email as a domain: SPF, DKIM in common selectors, DMARC, MX, MTA-STS and BIMI, with a 0-100 score and the fixes, most severe first. Public DNS only. Free, no account. Public DNS only, no account and no charge. The same domain is served from memory for 10 minutes. A network can run 30 new checks per day. DKIM is looked up in common selectors only; `dkim_not_found` does not prove that no key exists. `incomplete: true` means a DNS answer failed and the score can be lower than the real one; `unread` names those parts, and a failed query never becomes a missing finding.

Discovered
commsharbor_email_service_request

Request an included service with activation on demand. No guest access. Members can read. Owners, admins and organization keys can manage email. The private service credential stays on the server. Mailbox passwords and message content are never returned.

Discovered
commsharbor_email_trial_activate

Start the free receive-only Trial for 7 days, once per organization: 1 GB shared storage, unlimited mailboxes and no outgoing SMTP or external filter forwarding. No card, renewal or charge. After 7 days, writes without a paid plan answer 402 `email_trial_expired`. Requires a new workspace and operator-proved native quota. No guest access. Members can read. Owners, admins and organization keys can manage email. The private service credential stays on the server. Mailbox passwords and message content are never returned.

Discovered
commsharbor_email_workspace

Read the email workspace. We operate the mail server and webmail. Your agent manages the authorized domains and mailboxes through the existing service. Check checkout_live, domain readiness and observed sending capability. A payment or accepted job alone does not prove activation or delivery. Enterprise services can require activation on demand.

Discovered
commsharbor_email_workspace_snapshot

Read the current email workspace, DNS progress and recent jobs. The ID must match X-Organization-Id. Membership is checked again for each snapshot and delivered event. Events contain only an opaque change ID. DNS checks run in the private backend, with a 24-hour deadline and a visible resume action after pause.

Discovered
commsharbor_health

Read deployment health and build. Smoke tests wait for their own commit to appear here instead of racing edge propagation.

Discovered
commsharbor_logout

Revoke the current session. Bootstrap/CSRF must belong to this browser and session. Other product sessions remain active.

Discovered
commsharbor_me

Read the current account profile and platform role. `user.id` is the shared-account ID. Organizations are not listed here: they live in the shared account, which does not list them inside products yet — open a workspace by its ID with `GET /api/organizations/{organization_id}`.

Discovered
commsharbor_organization_get

Open an organization by id: name, your role and the CommsHarbor plan. This is how a workspace is opened. Name and role come from the shared account (null with an organization API key, which carries neither); the plan is the organization's global entitlement in CommsHarbor.

Discovered
commsharbor_platform_context

Confirm the caller's platform role. Tenant ownership grants nothing here: platform access is a separate, explicit grant.

Discovered
get_api_x402_email_check

Checks the email security of a domain for an agent, paid per call: SPF, DKIM, DMARC, MX and a score, with no account. The check of `GET /api/email-check`, sold per call to agents, with no account and without the 30 free checks per day before. A request without payment gets the 402 with the price; a paid one gets the audit in the same response, with the payment in `cobranca`. DKIM is looked up in common selectors only; `incomplete: true` means a DNS answer failed. A refused domain, the hourly limit of the service and a failed DNS lookup are not charged. DNS lookups, record parsing and assembling the domain's email-policy findings. DKIM checks common selectors only. Inspect incomplete and unread. A score does not prove inbox placement, stop every phishing attack or verify the contents of a mailbox.
