Overview

AI-generated overview

Gives an assistant read-only neutral prices and PSA population data for PSA-graded vintage Pokémon cards from the WotC 1999-2003 era.

What you can do
This remote MCP server exposes pricing and PSA population information for PSA-graded vintage Pokémon cards, specifically the Wizards of the Coast era from 1999 to 2003. The registry description says the data is neutral and the server is read-only. No individual tools are listed in the manifest, so the exact operations are not documented here.
When to use it
Use it when you want an assistant to look up or discuss market prices and PSA population figures for PSA-graded vintage Pokémon cards. It is not intended for grading submissions, purchases, or any action beyond reading data. Skip it if you need modern cards or non-PSA grading data, which the description does not cover.
Requirements
A remote MCP endpoint at using streamable HTTP. No packages, environment variables, headers, or authentication are declared, so no local runtime or API key appears to be needed. Network access to the provider is required.
Before you install
The description states the server is read-only, so no write, send, or delete actions are expected. No credentials, payments, or private data are requested in the supplied information. Because it is a remote endpoint, queries are sent to a third-party service, so consider what you share in requests.

Installation

In SourceWeft

  1. Open Gembook — PSA Vintage Pokémon Prices & Pop in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/xyz.gembook%2Fgembook/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
