An MCP (Model Context Protocol) server wrapping
map-price-monitor so AI agents
(Claude, OpenAI, LangChain, LlamaIndex, Cursor, Claude Desktop) can monitor
retail prices and detect MAP violations as native tool calls.
Responsible use. Every tool runs the upstream actor, which queries logged-out public product pages only - no accounts, no login, no CAPTCHA bypass, polite rate limits. Blocked retailers fail soft. Use within each retailer's terms and your own legal counsel's guidance.
Tools
| Tool | What it does |
|---|---|
scan_prices | Normalized public listings for one product across retailers (the raw price layer). |
check_map_violations | MAP violations for one product: advertised price below the threshold (supplied map_price or inferred advisory proxy), with graded severity, seller identity, and unauthorized-seller flags. |
match_across_retailers | Collapse one product into a single cross-retailer view (which retailers carry it, price spread, lowest offer). |
audit_sellers | Flag unauthorized third-party resellers of a product, with a below-MAP cross-reference. |
Retailers: target, bestbuy, newegg, walmart (fully parsed) plus
catalog-registered homedepot, lowes, costco, bhphoto, wayfair,
macys, microcenter.
Run modes
list_tools- emit the tool catalog (name, description, JSON schema) + the agentic-payment descriptor. Free.call_tool- invoke one tool. Requirestool+args.batch- invoke up to 10{tool, args}calls in one run.
{"mode": "call_tool","tool": "check_map_violations","args": {"query": "Sony WH-1000XM5","map_price": 399.99,"retailers": ["target", "bestbuy", "newegg", "walmart"],"authorized_sellers": ["Best Buy", "Crutchfield"]}}
Pricing
Flat $0.005 per MCP tool call (mcp_tool_call). The upstream actor charges
its own events to the same run as pass-through (listing_record $0.004,
sku_match $0.008, map_violation_flag $0.012).
Agentic payments
This server is x402 (USDC on Base) and Skyfire ready - an AI agent can pay
per tool call with no pre-provisioned API token when the operator enables MCP
monetization. The payment descriptor is advertised in the list_tools catalog.
Enable via env: X402_ENABLED, X402_PAY_TO_ADDRESS, SKYFIRE_ENABLED,
SKYFIRE_SELLER_ID.
