Bring completed eBay sales into Claude, ChatGPT, Codex, and other MCP clients. CompSniper cleans noisy matches before it calculates the median, so your answer is grounded in the product—not cases, parts, or the wrong model.
Sign in with your CompSniper account. No API key to paste into hosted connectors.

Based on 86 relevant completed sales after accessories, parts, and mismatched models were removed.
Representative MCP App result. Every answer also includes structured data the model can reason over.
From question to evidence
Your AI assistant chooses the right CompSniper tool, retrieves completed-sale evidence under your account quota, and returns structured data plus a compact visual summary.
Authorize your own CompSniper account through OAuth. The connector receives only the access needed to run the tools you approve.

“What does a used Shure SM7B sell for on eBay? Remove accessories and irrelevant listings.”
“Compare the resale value of a Steam Deck OLED, Nintendo Switch OLED, and ASUS ROG Ally.”
“I can buy a sealed HP W2132X toner cartridge for $90. Use sold comps and tell me whether to source or pass.”
“Run a deeper sold-comps search for a Sony A7 IV body and prepare the results for CSV export.”
Fifteen purpose-built tools
The connector exposes small, clearly annotated tools instead of one opaque action, so your assistant can use the least powerful operation needed for the job.
Search eBay, Poshmark, or Mercari listings, calculate price summaries, and check service or account status before a decision.
Evaluate several items together or measure the same product across supported eBay marketplaces.
Start a deeper asynchronous Max Mode sweep, check its progress, cancel it when appropriate, or export sold comps.
Private by design
CompSniper uses OAuth so each person authorizes their own account. The connector processes the tool request selected by your AI client; it does not receive your full conversation, unrelated files, Claude credentials, or OpenAI credentials.
See the full details in the privacy policy and MCP documentation.
OAuth grants are tied to the CompSniper account and scopes you approve. Hosted users never need to expose an API key in chat.
Sold-comp, comparison, quota, and status tools are read-only. Write and destructive annotations are reserved for Max Mode job actions that need them.
Each successful search uses the connected account’s request quota. Account tools let the assistant report usage and remaining requests directly.
