Common questions

Is BestPrice safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.9.0) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

BestPrice MCP

The official Model Context Protocol server for BestPrice.gr, Greece's price-comparison service. It gives AI assistants read-only access to shopping decisions, live product search, offer comparison, and price history. No account or API key is needed.

Start shopping

The BestPrice app for ChatGPT is available. Developer integrations can still call the public endpoint below.
Connect BestPrice to Claude using the prefilled connector form.
See the shopping guide for examples and other assistants.

For developer integrations, the public endpoint is:

https://mcp.bestprice.gr/mcp

Transport: Streamable HTTP over HTTPS; anonymous shopping, optional OAuth for Events
Official Registry ID: gr.bestprice/mcp
Server version: 1.9.0
Public guide: https://www.bestprice.gr/mcp
Support: https://www.bestprice.gr/contact

This repository holds everything that lives outside the hosted service: the install manifests for each AI client, a local stdio bridge for hosts that cannot speak HTTP, and the browser-native WebMCP layer. The server itself is not in this repository.

The current release matrix records the live gateway, UI, OAuth/Events, the ChatGPT directory listing and separate ACP qualification.

Tools

The hosted 1.9.0 service now also advertises check_deal and optimize_basket. Both passed a live check on 3 November 2026. check_deal accepts exactly one product URL, visible model/barcode text or selected product ID; image bytes are not ingested. optimize_basket calculates read-only plans for exact products, quantities and a supplied postcode. Neither places an order. The client manifests now advertise the six research tools. OpenAI's acceptance of the new server definitions and the 1.3.0 package are tracked in the release matrix.

Tool	What it does	Key arguments
`get_shopping_decision`	Runs the BestPrice Shopping Brain: an evidence-backed recommendation, need-based comparison, or read-only basket plan with reasons, tradeoffs, and unknowns.	`message` (the need in Greek or English, including any budget), optional `postal_code` (required for a completed basket plan), optional `evidence_detail` (`summary`, the default: only the evidence the answer cites; `full`: every claim and source)
`search_products`	Finds canonical products in the catalog. Returns product IDs and the catalog minimum price before shipping.	`query` (2–400 characters: a name, model, category, or a bare GTIN/EAN barcode), optional `price_min`, `price_max`, `required_features`, `sort` (`relevance`, `price_asc`, `price_desc`), `limit` (1–8)
`compare_offers`	Compares current merchant offers for one exact product, separating item price, shipping, and delivered total.	`product_id` from a previous result, optional `postal_code` (a Greek postcode, 10000–85999, for delivered totals), `objective`, `in_stock_only`, `minimum_merchant_rating`, `limit` (1–10)
`get_price_history`	Summarises how a product's price moved over time, against its 180-day median.	`product_id`, optional `period_days` (30, 90 or 180)
`check_deal`	Checks exact identity, current offers and price context for an offer.	Exactly one `url`, visible model/barcode `query`, or selected `product_id`; optional supplied `observed_price` and `postal_code`
`optimize_basket`	Calculates read-only plans for exact selected products and quantities.	`items` with `product_id` and `quantity`, Greek `postal_code`; optional `objective` and `maximum_merchants`

Public research tools are read-only. They never place orders, create alerts, or read account data. Results link to a BestPrice product page, never directly to a merchant. Unknown shipping is reported as unknown, not as free. Search covers safe physical products; digital goods, services, and age-restricted categories are excluded.

One optional clarification

A broad request can return outcome: "clarification" with clarifications[].choices. Each choice contains a display label and a self-contained message. Ask the shopper to choose, then call get_shopping_decision with that message. When they choose Skip, also send skip_clarification: true as returned by that choice. Never choose on the shopper’s behalf. Exact models and requests that already state the missing type bypass this step. Mandatory budget, age-group, product-type and accessory checks still apply after Skip.

For example, “ANC headphones up to €150 for commuting” can ask whether the shopper wants over-ear or in-ear headphones. The recommendation excludes children’s models and replacement accessories unless the shopper asks for them. This is the same Shopping Brain used by BestPrice Ask.

Ask’s product cards can open BestPrice’s existing alert and saved-list flows. Public research remains read-only. On an MCP Events-capable host, optional account linking can separately create and cancel the exact price alerts the shopper requests. No alert is active until subscription succeeds. Saved comparisons in the 1.3.0 candidate remain separately gated; account conversations and image bytes are not accessed.

Protocol details

Measured against the live endpoint on 24 September 2026.

Versions. initialize negotiates 2025-11-25, 2025-06-18, 2025-03-26, 2024-11-05 and 2024-10-07; a client that asks for any other version is answered with 2025-11-25. The 2026-07-28 per-request revision is also served: send the MCP-Protocol-Version, Mcp-Method (and, for tools/call, Mcp-Name) headers, and put io.modelcontextprotocol/protocolVersion and io.modelcontextprotocol/clientCapabilities in every request's _meta. A request that names the revision without that envelope is refused with -32602.
Stateless. No MCP-Session-Id is issued and none is required; DELETE answers 405. A GET with Accept: text/event-stream answers immediately with the SSE comment : connected and retry: 300000, then holds the connection open. It does not send JSON-RPC requests or notifications on that stream. Rechecked 29 October 2026. A client loses nothing by not opening it, and must not wait for the stream to end.
Capabilities. tools and resources are available to compatible clients. The resource surface contains the optional MCP Apps UI at ui://bestprice/shopping-results-v1.html, the server card at mcp://server-card.json, and the canonical skill://bestprice-shopping/SKILL.md. On MCP 2026-07-28 the server also declares the final io.modelcontextprotocol/skills extension: skills/list and skills/get return the one BestPrice Shopping Skill with its SHA-256 digest and byte size, and resources/read returns the exact markdown bytes. Older clients simply see the Skill as an ordinary resource. There are no prompts, completions or logging; those methods answer -32601.
Responses. A client that accepts both application/json and text/event-stream gets a one-event SSE response. Accept: application/json, */* or no Accept header gets a single JSON body. Every tool returns structuredContent that validates against its outputSchema, plus the same result as text for clients that do not pass structured content to the model.
Errors. An unknown tool is a JSON-RPC error (-32602). Invalid arguments and service failures such as an unknown product are tool results with isError: true, so the model can read and correct them.
Limits. JSON request bodies up to 256 KiB (413 above that), a 12-second request deadline, and per-client rate limits answered with HTTP 429, JSON-RPC error -32029 and a Retry-After header. JSON-RPC batch arrays are refused with 400.
Browsers. Desktop, CLI and server-side clients send no Origin header and are not affected. A browser page may call the endpoint from an allowlisted AI-host origin, from bestprice.gr, or from localhost (so MCP Inspector works in direct mode); any other origin gets 403.
Authentication. The six research tools work without an account. Optional account linking is scoped to events:subscribe; protected-resource metadata is available at /.well-known/oauth-protected-resource and /mcp/oauth-protected-resource. Actual host subscription and delivery qualification is recorded separately in the release matrix.

Developer quick start

Every client below connects to the same endpoint. Copy-paste connector setup for Perplexity, Claude, ChatGPT developer mode, Gemini CLI, Copilot, Grok Bot, and Cursor is in docs/connect.md. Longer provider notes, including OpenAI and Microsoft Copilot Studio, are in docs/provider-setup.md.

Claude

Connect BestPrice to Claude opens the custom-connector flow with the endpoint prefilled. For Claude Code:

claude mcp add --transport http bestprice-shopping https://mcp.bestprice.gr/mcp

The bundled .mcp.json is the equivalent project-scoped configuration.

Cursor

Add BestPrice to Cursor shows the decoded configuration before adding it. The .cursor-plugin/ directory holds the marketplace plugin and an agent skill.

VS Code and VS Code Insiders

Kiro

Add BestPrice to Kiro opens Kiro's confirmation dialog with the remote URL. Kiro shows the configuration before writing it.

Gemini CLI and Qwen Code

gemini extensions install https://github.com/TheBestCo/bestprice-mcp

qwen extensions install https://github.com/TheBestCo/bestprice-mcp --consent

Both extensions restrict the imported tools to the four listed above.

Codex, Claude plugins, and Agent Skill hosts

The root plugin.json, mcp.json, and skills/bestprice-shopping/SKILL.md form a portable Agent Plugins package: the MCP supplies live shopping data and the Skill teaches the host when and how to route unbranded Greek shopping intent. Agent-compatible hosts that discover repository-local skills under .agents/skills/ get the same canonical workflow at [.agents/skills/bestprice-shopping/SKILL.md](.agents/sk
