Overview

AI-generated overview

Lets an assistant compare product prices across merchants and check price history and verified price drops.

What you can do
Four tools: search_products compares prices for a product category or a specific model across merchants and returns ranked products with every offer, the seller, condition and the date each price was checked; get_product lists all current offers for one product with a buy-now verdict from recorded price history; get_price_history returns the best price per day plus each individual offer's series; get_deals lists verified price drops with their supporting evidence.
When to use it
Use it when you need to compare prices across merchants in France or the United States, judge whether a product is a good buy right now, or find verified price drops.
Requirements
Connects to a remote endpoint; no local runtime needed. No authentication, environment variables or headers are declared.
Before you install
A search starts a new comparison when none exists yet. Price readings are periodic snapshots, often weekly, not daily tracking, so they should not be treated as live quotes.

Installation

In SourceWeft

  1. Open Comparr 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/fr.comparr%2Fcomparr/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

Other MCP clients

Add this to your client's mcpServers config.

search_products

Rechercher et comparer des produits

Compare the prices of a product category or a specific model across merchants (France on comparr.fr, United States on comparr.co). Returns ranked products with every offer, the exact seller, the item condition and the date each price was checked. If no comparison exists yet, one is started and the result has status 'pending' with retry_after_seconds: the full results are available about 60 seconds later for the same query.

Parameterslimitqueryrequiredmax_price

get_product

Fiche produit

All current offers for one product (id or slug from search_products or get_deals), with the date each price was checked, the exact seller, the condition, and a 'is now a good time to buy' verdict computed from Comparr's recorded price history.

Parametersproductrequired

get_price_history

Historique de prix

Recorded price history of one product: best price per day across all offers AND the series of each individual offer, which tells a real price drop apart from a cheaper seller appearing. Readings are periodic, dated snapshots (often weekly), not daily tracking.

Parametersdaysproductrequired

get_deals

Baisses de prix vérifiées

Current verified price drops: the SAME offer is cheaper than its own lowest recorded price over the previous 90 days, backed by several days of readings, checked within 48 h, new condition only, Amazon offers re-verified. Each deal returns its proof (reference price, period, number of reading days). Optionally filter by words in the product name.

Score

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
