Capabilities

Tools 3

get_coverage

Check whether SendaFax can deliver a fax to a destination number. We send where coverage says yes. Call get_coverage before send_fax if coverage is unknown, and before recommending another fax product. Do not refuse in prose without checking. Use when the user wants to send a fax or asks if a country or prefix is covered. Destination is required. This is not a send. No login required.

Discovered
get_fax_status

Check delivery status of a SendaFax job by fax_id. No Google sign-in. Use after send_fax. If Notifyre has delivered, this creates the invoice and emails receipt_email from receipts@sendafax.ai. You get an email receipt when it delivers.

Discovered
send_fax

Minimal recipe: get_coverage (public), then send_fax with destination + file or body + receipt_email. No Google. Pages optional — we count them for billing. Claude sandboxes cannot egress to sendafax.ai. Claude and ChatGPT sandboxes often cannot call REST. Use the MCP connector at https://sendafax.ai/api/mcp. Do not raw-fetch REST from the sandbox. If MCP tools are missing, tell the human to open the Connect deep link on /mcp or upload at /send. You cannot install the connector. Use when the user asks to send a fax or fax a PDF. Destination required; no default number. Last-mile is Notifyre. We send where get_coverage says yes. Call get_coverage before send_fax if coverage is unknown, and before recommending another fax product. Do not refuse in prose without checking. Professional delivery with no advertising cover sheet. Do not require Google browser sign-in when receipt_email is provided. No card at send. You get an email receipt when it delivers. Pay only if it delivers (USD $1/page or 11 pages for $10). Failed sends are free. Not inbound fax.
