DarkFunnels — MCP server

A hosted, multi-tenant MCP server that lets your assistant operate a WhatsApp AI sales agent: audit real conversations and find where sales are lost, edit the versioned sales playbook with undo, manage the product catalog, and read orders, stock and metrics — all scoped to your own account.

This repository is the public front door: the server itself is closed source.

Read the documentation first — no account needed

• Public docs MCP server (no auth): https://docs.darkfunnels.ai/mcp — search every page and browse a read-only virtual filesystem of the documentation. Registry entry: ai.darkfunnels/docs.
• Skill file: https://docs.darkfunnels.ai/skill.md — npx skills add https://docs.darkfunnels.ai.
• Plain text: https://docs.darkfunnels.ai/llms.txt and https://docs.darkfunnels.ai/llms-full.txt; append .md to any docs URL.

Connect

https://mcp.darkfunnels.ai/mcp?features=all

• Transport: Streamable HTTP, stateless. No SSE; GET/DELETE on /mcp answer 405.
• Auth: OAuth 2.1 with dynamic client registration. Nothing to request from us and no waiting list — any DarkFunnels account can connect.
• Discovery: https://mcp.darkfunnels.ai/.well-known/oauth-protected-resource/mcp (RFC 9728). An unauthenticated call answers 401 with a WWW-Authenticate: Bearer resource_metadata=… header, which is what makes a compliant client start the flow on its own.

Authorize with the same account you use for the dashboard. Authorizing with a different one connects successfully to that other, probably empty, workspace — if your assistant says you have no products, check that first. The whoami tool answers which account is connected.

What it is for

DarkFunnels puts an AI sales agent on a business's WhatsApp. The business connects the number it already uses by scanning a QR code from the dashboard, the same linked-device mechanism as WhatsApp Web: there is no Meta Cloud API application to get approved, no message templates to submit, and no per-conversation fee. DarkFunnels is not a Meta product and is not affiliated with Meta.

This server is how the owner's own assistant — Claude, ChatGPT, Codex or any MCP client — operates that workspace.

Scoping the connection

Four query parameters decide what the assistant can do:

• ?features= — an explicit list replaces the default set, it does not extend it. ?features=all is the recommended value: it takes the whole catalog, including groups published after you connect. A _write group always brings its matching read group with it.
• ?read_only=true — disables every write, and takes precedence over everything else, all included.
• ?pii=full — unmasks end-customer phone numbers, which are masked by default.
• ?agent=<uuid> — pins the connection to one sales funnel.

Without ?features=, the default set is read-only apart from a single non-destructive write: assigning tags to customers.

Tools

44 tools across 14 feature groups. Every one declares a title and the applicable readOnlyHint or destructiveHint, so a client can show the owner what it is about to do.

Tool titles and descriptions are written in Spanish. That is deliberate: it is the exact text the connector sends to the model, refined against real operational failures in a product whose users are Spanish-speaking business owners. Translating it would describe a tool that does not exist.

What it will never do

This connector never moves funds and cannot execute payments. Order and sales data is read-only: nothing in the tool surface initiates, captures, or refunds a payment.

One tool creates a sales funnel, which consumes a subscription seat. It never initiates a payment: when the seat limit is reached the call fails closed, and the owner completes any purchase in the DarkFunnels dashboard.

Try it with these

1. "Review yesterday's WhatsApp conversations and tell me where we are losing sales."
2. "Read my sales agent's manual and propose an improvement to the closing chapter; save it once I approve."
3. "List the customers who have gone 3+ days without a reply and draft what the agent should say to re-engage each one."
