PromptFax is a pay-per-use remote MCP server that lets an AI assistant send a real fax to a US fax number. Your assistant uploads a PDF or image, enters the destination, reviews a quote, opens Stripe Checkout, and queues the transmission. Pricing is $2.00 for the first 5 pages, then $0.10 per page after that, capped at $4.50 for up to 35 pages. Payment is captured only after the fax is recorded as delivered. There is no PromptFax account, no subscription, and no API key to manage. PromptFax uses OAuth and Streamable HTTP, so users install once and their assistant can start a fax workflow when needed. Inside ChatGPT, PromptFax opens a connector widget that handles document review, destination entry, Stripe Checkout, and the delivery report. Inside Claude or other MCP hosts, PromptFax falls back to an agent-friendly hosted session page that handles the same flow without requiring the host to pass files directly. Every real send requires a user-reviewed quote and Stripe authorization. The assistant cannot silently complete a fax. The `send_fax` and `cancel` tools are marked as destructive so well-behaved MCP hosts can surface confirmation steps. ## Capabilities - Send outbound faxes to US fax numbers - Attach a PDF or image from the host, widget, hosted session page, or HTTPS URL - Generate a pay-per-use quote before payment - Open Stripe Checkout for payment authorization - Queue a paid fax for transmission - Check workflow, payment, and delivery status - Retry eligible failed faxes - Cancel an active send while cancellation is still possible ## Tools - `start_session` — Create or resume a PromptFax MCP session. - `attach_document` — Bind a PromptFax document or HTTPS PDF URLs to an MCP session. - `get_quote` — Create a fax quote from a session, document, or HTTPS PDF URL. - `checkout` — Open Stripe Checkout after the user accepts a quote. - `send_fax` — Queue a paid fax for transmission. - `get_status` — Fetch workflow, payment, and transmission status. - `retry_failed_fax` — Prepare a retry flow after a retry-eligible failed fax. - `cancel` — Cancel the active send while cancellation is still possible. ## Common use cases - Sending a one-off medical record, referral, or intake form to a clinic's fax line. - Returning a signed contract to a small business or law office that still operates by fax. - Sending insurance claim forms, prior-authorization paperwork, or appeal letters. - Sending a benefits or HR form to a payroll vendor that requires fax submission. - Sending court filings or notarized documents to a filing office. ## Data handling PromptFax does not require an email address, does not provision a PromptFax account, and stores uploaded documents only as long as the fax workflow needs them. Server-side working copies are deleted after transmission. The browser-local delivery report persists for up to 24 hours unless cleared sooner. PromptFax is outbound-only and currently supports US fax numbers only. Payments are processed by Stripe for Cogint Labs LLC. ## Links - Homepage: https://promptfax.app/ - MCP endpoint: https://promptfax.app/mcp - Setup docs: https://promptfax.app/mcp-setup - Tool catalog: https://promptfax.app/mcp-tools - Demo: https://promptfax.app/mcp-demo - Pricing: https://promptfax.app/pricing - Privacy: https://promptfax.app/privacy - Terms: https://promptfax.app/terms

**Your company's brain for AI agents.** Quelvio continuously understands your organization's knowledge across every connected system — what's authoritative, what's recent, what's persistent, what's temporary, and what should be forgotten. Returns cited answers grounded in your authoritative sources, refusing when the corpus doesn't actually answer the question. ## What makes Quelvio different - **Cross-document supersession** — when sources conflict, surfaces the current truth and explicitly names what it supersedes - **Authority-weighted retrieval** — weights documents by who said them on the relevant topic - **Refuses on weak context** — when the corpus doesn't actually answer, says so. No hallucinated numbers, no fabricated citations - **Cross-source synthesis** — reasons across Slack, Confluence, Notion, Drive simultaneously with explicit source attribution - **Lifecycle awareness** — tracks current vs deprecated content, flags stale procedures ## Tools - `query_knowledge` — search across all connected sources with optional synthesis modes (fast / standard / deep) - `list_domains` — discover what knowledge domains your tenant has indexed - `get_source_detail` — chunk-level provenance for any cited result ## Setup 1. Sign up at https://quelvio.com — 5GB indexed + 2 queries/day free tier 2. Connect your sources (Google Drive, SharePoint, Confluence, Slack, Notion, GitHub) 3. Add this MCP server to your client 4. Complete OAuth on first tool call ## Authentication OAuth 2.1 with PKCE. Per-employee identity propagation — each query is scoped to the individual employee's permissions in source systems. ## Pricing Per Knowledge Token model. Paid plans scale with usage and seats.
