How do I install the Store Price Tracker MCP server?

Store Price Tracker is a hosted endpoint at https://stores.openkrill.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_store_prices ~259

Read an online store's products, prices and availability, and what changed since its previous daily snapshot. Use it for questions like "track competitor prices on allbirds.com", "what did gymshark.com change?", "did this store drop prices?", "what is new or sold out at this store?". Pass store web addresses, up to 5. Works for stores on Shopify that publish their public product feed (/products.json). The store is added to a daily snapshot list, so its history builds up. Optional filters: query (text in a product's title, brand or type), limit. Returns per store the snapshot date, product count, currency, counts and lists of new products, removed products, price changes and availability changes per variant, and matching products with price, variants and availability. The first snapshot of a store has no changes to compare with.

NameTypeReqDescription
limitinteger–Most products listed per section (default 10)
querystring–Only products whose title, brand, type or handle contains this text, such as "hoodie"
storesarrayyesWeb addresses of online stores, such as "allbirds.com" or "https://www.gymshark.com". At most 5.

compare_store_prices ~577

Compare product prices between two online stores to find price gaps, spreads, and margin differences. Use it for questions like "compare prices between allbirds.com and allbirds.co.uk", "find the price gap for hoodies between two stores", or "which store sells this item cheaper?". Pass source_store and target_store web addresses. Supports cross-currency comparison: when stores quote in different currencies, prices are normalized using European Central Bank (ECB) daily reference rates via Frankfurter (https://api.frankfurter.dev, checked 2026-10-02). Optional filters: target_currency (defaults to target store currency), fx_rate (manual override), shipping_allowance (freight cost deduction), duty_allowance, include_landed_duty (EU flat customs duty), query (text in title/brand/category), match_by ("title", "sku", "handle", default "title"), and min_gap_pct (minimum percentage difference, default 0). Returns matched products with local and converted prices, exchange rate, rate date and source, price gaps, percentage spreads, stock availability, canonical links, and landed margin differences.

NameTypeReqDescription
duty_allowancenumber–Optional flat customs duty allowance per item in target currency to deduct for net landed margin evaluation. When omitted and include_landed_duty is true, defaults to EU flat duty (€3 converted to ta…

shipping_allowancenumber–Optional estimated flat shipping allowance per item in target currency to deduct for net landed margin evaluation. Default 0.

get_feedback_reply ~84

Read the feedback reply for a ticket from submit_feedback. Use this to read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id.

get_product_price_history ~185

Read how one product's price and availability moved over the days a store has been tracked. Use it for questions like "how has the price of this hoodie changed?", "when did this product go on sale?", "has this been out of stock?". Pass the store's web address and the product's link, handle or title (or part of it). Returns per variant the price, the compare-at (was) price and availability on each day something changed, from the first snapshot to now. History starts when the store was first tracked; a store never asked about before has a single snapshot. Several matching products come back as a list of titles to choose from.

LinkedIn recruiter jobs feedback broken links: search openkrill MCP tools by task. Use this to find a tool for recruiter search, LinkedIn keywords, jobs, feedback, a missing tool, bug reports, broken links, CVEs, packages, a domain check, or any other task. Lists tool name, a plain task phrase, and the MCP URL to connect. Feedback itself is submit_feedback on this same server.

Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
