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) — see Endpoints for the creator-campaign endpoint
• 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.

Endpoints

The server mounts the same MCP implementation at two URLs, each serving a different tool profile (src/tools/index.ts):

The creator profile is the connector as a creator-campaign product: a brand commissions creators, and creators are paid for original content they publish from their own accounts. boost_post is the one tool that does not fit — it sells likes and repost, which are engagement signals, and accepts Instagram post URLs — and Meta's Spam community standard bars paying for engagement. So it is excluded from /creator pending Meta approval, after which it can be added back.

The split is by URL rather than by OAuth client on purpose: tools/list is deliberately unauthenticated (so directory health checks can introspect), which means a reviewer can list tools before any client identity exists. Prompts and the productclank://capabilities resource are filtered the same way, so nothing the creator endpoint serves mentions boosts, likes or reposts.

Both endpoints share one OAuth authorization server, one set of tokens, one session sweeper and the same JSON-only-client handling; each is its own RFC 9728 protected resource (/.well-known/oauth-protected-resource/mcp and …/creator).

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

1. Approve the OAuth prompt — it signs you into ProductClank (Google or email) and asks for consent.
2. 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?"

Getting new tools: Claude loads the tool list when a conversation starts. After we ship a new tool or option, start a new conversation to see it. In Claude Code, run /mcp and reconnect ProductClank (or start a new session).

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

1. Choose OAuth as the authentication method and connect — it signs you into ProductClank (Google or email) and asks for consent, exactly like Claude.
2. 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

Grow — run growth campaigns for a product

| boost_post _(/mcp only — see Endpoints)_ | Rally the community to engage a specific post — AI-drafted replies or quote posts at 20 cr per draft (count 1–10, default 10 = 200 cr; quote posts X only — a repost with each member's own text, landing in their followers' feeds), 30 likes, 10 bookmarks (X only) or 10 reposts (300 cr). Auto-detects platform from the URL: X, Instagram, TikTok, LinkedIn, Reddit, Farcaster, YouTube | 20 cr/draft or 300 cr |

Earn — participate in campaigns for the connected user

Content Studio

| get_quote_authority _(/mcp only)_ | Quote authority on a space: the people pinned to quote, the latest moments, the plan | free | | suggest_quote_people _(/mcp only)_ | People on X the brand's audience already trusts, each checked against the X account lookup | first free, then 50 cr | | find_quote_moments _(/mcp only)_ | One live X search for the pinned people's clearest claims (posts and clips) | first free, then 50 cr | | draft_quote_post _(/mcp only)_ | Draft quote posts for one moment, with the user's take on top. The user quotes and posts it themselves | free |

Credits

The server also exposes two MCP prompts — grow_product, a ready-made operating procedure for the growth loop, and setup_content_space, the Content Studio onboarding interview (brand → audience → tone → example posts → platforms → post types → topics, then first drafts and the approve / tweak / teach loop) — and a resource — productclank://capabilities, the tool/cost roster — so agents can plan spend before calling anything.

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").

Communication contract

Tool results are read by an assistant, not by the
