ProductClank MCP Server

Launch community growth campaigns from your AI assistant. ProductClank turns real communities (and their agents) into a distribution network — this MCP server lets Claude, ChatGPT, or any MCP client rally that network on your behalf: boost a post with real replies, likes, and reposts; launch community content campaigns; draft social content into your own pipeline.

• Remote server: https://mcp.productclank.com/mcp (Streamable HTTP)

• Auth: OAuth 2.1 — sign in with your ProductClank account, revoke anytime

• Billing: your ProductClank credits, per-tool costs shown below, with per-app daily spend caps

• Website: productclank.com/mcp

The same URL works in both Claude and ChatGPT — the only difference is where each app hides its "add a connector" screen (and, for ChatGPT, a plan/Developer-mode requirement). Once connected, both drive the identical tools below.

Connect from Claude

1. In Claude, go to Settings → Connectors → Add custom connector (Desktop or web).

2. Paste the URL:

   https://mcp.productclank.com/mcp

3. Approve the OAuth prompt — it signs you into ProductClank (Google or email) and asks for consent.

4. Ask Claude things like:

   "Boost this post with replies from the ProductClank community: https://x.com/…" "Preview a content campaign for my product." "What's my ProductClank credit balance?"

Connect from ChatGPT

ChatGPT reaches custom MCP connectors through Developer mode.

Requirements — Custom connectors need a paid ChatGPT plan (Pro, Plus, Business, Enterprise, or Education) on the web app. They are not available on the free tier, so free-tier users won't see an "add connector" option — this is a ChatGPT limitation, not a ProductClank one.

1. In ChatGPT on the web, open Settings → Apps & Connectors → Advanced settings and turn on Developer mode.

2. Back in Apps & Connectors, click Create / Add custom connector.

3. Give it a name (e.g. ProductClank), a short description, and the MCP server URL:

   https://mcp.productclank.com/mcp

4. Choose OAuth as the authentication method and connect — it signs you into ProductClank (Google or email) and asks for consent, exactly like Claude.

5. In a chat, enable the ProductClank connector and ask it to boost a post, preview a campaign, or check your balance.

Works in any MCP client that supports remote servers with OAuth (Claude web/desktop, Claude Code, ChatGPT Developer mode, and others).

Tools

Costly actions are designed to be confirmed with the user first — tool descriptions instruct the model to preview and state the credit cost before spending.

How auth & billing work

The server is an OAuth 2.1 authorization server backed by the ProductClank web app (/connect/mcp login + consent). Every /mcp request requires a valid access token; tools act as the connected user and bill that user's credit balance. Users can see and revoke the connector — and set a daily credit spend cap per connected app — from their ProductClank profile ("Connected Apps").

Architecture

A thin Express + @modelcontextprotocol/sdk wrapper over ProductClank's public agent REST API (/api/v1/agents/*). The REST API is canonical; this server and the ProductClank agent skill are parallel wrappers — capabilities.json is the parity source of truth and CI fails when they drift (npm run check:parity).

Claude / MCP client ──▶ mcp.productclank.com/mcp (this server)
                          │  OAuth 2.1 AS ──▶ productclank.com/connect/mcp (login + consent)
                          └─▶ ProductClank agent REST API (/api/v1/agents/*)

Development

cp .env.example .env   # fill in (see DEPLOYMENT.md)
