Ask your AI assistant about your collection

Connect Claude, ChatGPT or any MCP-ready assistant to CollectionPlnr and talk to your collection in plain English. What is it worth? Which issues are you missing? What should you pre-order before cut-off? Your assistant answers from your own collection and our full catalogue, with a link to every item.

What your assistant can do

Questions to try

• “What is my collection worth, hobby by hobby?”
• “Which ten items in my collection are the most valuable?”
• “Which issues am I missing from my Amazing Spider-Man run?”
• “How close am I to finishing my Pokemon 151 set?”
• “What comes out in the next 30 days for the series I follow, and when is final order cut-off?”
• “What is a sealed Millennium Falcon 75192 worth today?”
• “Which comic series are heating up right now?”
• “What did I add to my collection this month?”

Your assistant picks the right lookup on its own, combines the answers and links you straight to each item page, so you can check the detail or add to your collection in one click.

Set it up in two minutes

1. Sign in and open Account settings. Under Connect AI assistants, create a token and give it a name such as Claude. Copy it straight away: for your security it is shown once.
2. Add CollectionPlnr to your assistant with the server URL and your token, as shown below.

Bearer cp_your_token

Claude is rolling Request headers out account by account. Not there yet? Use Claude Code, or the desktop config under Other MCP clients. In Claude Code, one command does it:

claude mcp add --transport http collectionplnr https://www.collectionplnr.com/mcp --header "Authorization: Bearer cp_your_token"

ChatGPT

ChatGPT connects apps through a sign-in flow, so Sign in with CollectionPlnr for ChatGPT is next on our list and will appear here the moment it is live. If you build with OpenAI's Responses API or Agents SDK, connect today: pass the server URL and send your token as the Authorization header.

Other MCP clients

Cursor, VS Code, Windsurf and every client that speaks remote MCP over Streamable HTTP with a custom header connect with an entry like this in their MCP config:

{
  "mcpServers": {
    "collectionplnr": {
      "url": "https://www.collectionplnr.com/mcp",
      "headers": {
        "Authorization": "Bearer cp_your_token"
      }
    }
  }
}

Clients that only launch local servers, including Claude Desktop's config file, bridge through mcp-remote:

{
  "mcpServers": {
    "collectionplnr": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://www.collectionplnr.com/mcp",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer cp_your_token"
      }
    }
  }
}

Private by design

• Read-only. Tokens can look things up. They cannot add, change or delete a single item.
• Your data only. A token sees your collection, your wishlist and the public catalogue. Never anyone else's collection, and never your email, notes or what you paid.
• Revocable in one click. Revoke a token in Account settings and it stops working on the very next request. Each token shows when it was last used.
• Stored safely. We keep only a one-way fingerprint of each token, never the token itself, which is why it is shown to you once.

Your assistant provider sees the answers it fetches for you, just as it sees anything else you share in a chat. Read our privacy policy for how CollectionPlnr handles your data.

What your plan unlocks

Connecting an assistant is free on every plan, and so are catalogue search, item values, your collection and wishlist, gap finding and the release calendar. Starter adds your collection's total value, hobby by hobby. Pro adds Signals. Compare plans.
