Use eBay sold prices in ChatGPT

Open Plugins in ChatGPT and search for CompSniper.
Choose Connect, then sign in to CompSniper or create a free account.
Ask in plain English: "What did a PSA 10 Charizard 199/165 sell for on eBay in the last 30 days?"

ChatGPT answers from real completed eBay sales and shows the median, the realistic range and how many sales it used, so you can see the price is grounded in data and not a guess.

Use it in Claude and Claude Code

CompSniper is published in the Claude Connectors Directory. Choose Connect, sign in, then enable CompSniper from the Connectors menu in a conversation. It works on Claude web, Claude Desktop and mobile.

In Claude Code, add it once for every project:

claude mcp add --transport http --scope user compsniper https://mcp.compsniper.com/mcp
claude mcp login compsniper

Use it in Codex, Cursor, VS Code and other MCP clients

Any client that supports remote Streamable HTTP servers with OAuth can connect to https://mcp.compsniper.com/mcp. No static API key or header is needed. For Codex:

codex mcp add compsniper --url https://mcp.compsniper.com/mcp
codex mcp login compsniper

Step-by-step setup for every client is in the MCP install guide.
