What this is
ASINBuyer runs a remote MCP (Model Context Protocol) server, so you can connect your workspace to Claude and ask about your outreach in plain language — “list my campaigns and how each is doing,” “show the buyer segments for my KitchenHex product,” or “analyze this Amazon ASIN and find B2B buyers.”
There are two ways to connect, depending on which Claude you use.
Option 1 — Claude desktop app (recommended)
No API key needed. Claude signs you in to ASINBuyer directly.
- In Claude, open the connectors settings and choose to add a custom connector.
- Paste the server URL
https://asinbuyer.com/api/mcpand leave the OAuth fields blank. - Add it, then click Connect. An ASINBuyer sign-in window opens.
- Approve access. Read-only is the default; tick the box to also allow product analyses (which spend Buyer Credits).
You can revoke access at any time from API & MCP in your dashboard.
Option 2 — Claude Code (API key)
Create a workspace API key in API & MCP, then add it to Claude Code:
claude mcp add --transport http asinbuyer \ https://asinbuyer.com/api/mcp \ --header "Authorization: Bearer <your-key>"
Read-only keys can browse; full keys can also run analyses that spend Buyer Credits.
Available tools
| Tool | What it does |
|---|---|
| Get credit balance | Your Buyer Credits balance, plan, and monthly allowance. |
| List products | The Amazon products in your workspace. |
| Get product details | One product with its B2B angle and ranked buyer segments. |
| List campaigns | Your outreach campaigns with status and credit detail. |
| Get campaign details | One campaign by id with status and credit detail. |
| List AI calls | Outcomes, sentiment, and summaries of AI follow-up calls. |
| Analyze Amazon product | Research a new ASIN — generates the B2B angle and buyer segments. Spends Buyer Credits and needs full access. |
Every tool except Analyze Amazon product is read-only. Analysis is the only action that writes data and spends credits, and it requires a full-access connection.
Access & security
The desktop connector authenticates with OAuth 2.0 (authorization code with PKCE); Claude Code uses a workspace API key sent as a Bearer token. Either way, access is scoped to your own workspace — a connection can never read another customer's data. Two access levels are available: read-only (browse) and full (also run analyses that spend Buyer Credits). All traffic is over HTTPS.
