For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/synchronity-mcp-9e7301ff79
GET https://www.mcpbundles.com/api/directory/v1/servers/synchronity-mcp-9e7301ff79?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/synchronity-mcp-9e7301ff79/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/synchronity-mcp-9e7301ff79/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

List all registered e-commerce sites. Use this first to find a site by name (e.g. "Pronto Partners") and get its site_id, which is required by all other tools.
List Sites — List all registered e-commerce sites. Use this first to find a site by name (e.g. "Pronto Partners") and get its site_id, which is required by all other tools.
Search Products — Find products on a registered store. To BROWSE a store's catalog (open-ended requests like "what do they sell", "show me what's available"), call with NO query — this returns the store's products. To SEARCH, pass `query` (a product name/keyword). Returns paginated products as an interactive card. ALWAYS translate a buyer's budget or price constraint into the price params on THIS call instead of filtering in your reply: "under/below/within X" or "X budget" → `max_price: X`; "over/above/at least X
Get Product — Retrieve detailed information about a specific product including variants, pricing, images, and availability. May also return `addons` — customer-selectable options defined by the store (e.g. engraving, gift wrap, size add-ons). When a product has addons, present them to the buyer and collect every addon with `required: true` before calling add_to_cart; for any option carrying a `price_modifier`, show that surcharge so the buyer knows the added cost. The card already shows the product details to
Get Product Reviews — 🔍 **RECOMMENDED STEP** — Fetch product reviews and authenticity consensus before making purchase decisions. Returns: average rating, trust score (0.0-1.0), review sentiment analysis, authenticity flags (fake reviews, seller issues, negative trends), and recent reviews with verified purchase status. Always call this for each product before adding to cart to verify quality and detect scams.
Request Back In Stock — Subscribe the buyer to a back-in-stock alert for an out-of-stock product. Use when the buyer asks to be notified/told/pinged when an item restocks ("notify me when X is back", "let me know when it's in stock"). Collect the buyer's email so the alert can reach them (without it only the demand is recorded for the merchant). The buyer is emailed when the product is next seen in stock. Returns whether an email alert was armed.
Compare Products — Compare products across multiple registered e-commerce sites simultaneously. Uses fail-open strategy: partial results from successful sites are returned even if some sites time out.

Operate Synchronity?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal
Create Cart — Create a new shopping cart for a specific site. Returns a cart_id. IMPORTANT: Reuse the active cart_id across multiple products in the same session. Do NOT call create_cart again if you already have a cart_id for this site in the chat history.
Add To Cart — Add a product variant (or base product) to an existing cart. Reuse the active cart_id from the chat history if one already exists. Only call create_cart first if no cart exists yet.
Quick Checkout — Assemble checkout-ready cart(s) in ONE call for a multi-product (and optionally multi-store) request. Creates a cart per store, adds all items, and sets the shipping address — then returns the cart(s) with delivery options to choose. Use this when the buyer lists several products at once (optionally across stores) and/or gives their address up front, instead of calling create_cart/add_to_cart/set_shipping_address separately. Does NOT select delivery, check out, or pay — the buyer picks delivery
Remove From Cart — Remove a line item from the cart. Requires the item_id from the cart contents.
Set Cart Quantity — Set a cart line's quantity (the server cart is the checkout source of truth, so this updates it live). Requires the item_id from the cart contents and the new absolute quantity. A quantity of 0 removes the line. Returns the updated cart card.
Apply Coupon — Apply a discount or promotional code to the cart. Returns the updated cart with discount applied.
Get Cart — Retrieve current cart contents, including items, pricing, discounts, and totals. The card already shows the line items and totals to the user, so keep your text reply to one brief sentence — do not re-list the cart contents.
Get Active Cart — Retrieve the buyer's in-progress cart for a site (resumes a conversation). Call this before assuming a new cart when a shopping conversation continues or after a cart error. Returns the cart with its items rebuilt if the connector cart expired, or null if no cart exists.
Set Shipping Address — Set the cart shipping destination (collected from the buyer) and return available shipping options with costs. Call after items are in the cart and before select_shipping_option. country_code is required; include postal_code/state for accurate rates.
Select Shipping Option — Select one of the shipping options returned by set_shipping_address. Binds the rate to the cart so the total includes shipping; call before execute_checkout so the hosted checkout opens pre-filled.
Execute Checkout — Execute checkout for a cart to create an order. Requires a buyer delegation token (from user auth) and a shipping address. The order is created UNPAID (status "pending"). IMPORTANT — do NOT stop here or just hand the user the payment_url. Immediately continue the in-chat payment flow: call get_payment_methods for the returned order_id, present the available channels to the buyer, and ask which they want to use; then drive initiate_payment → (submit_payment_otp if needed) → poll get_payment_statu
Get Order — Retrieve details for an order by its ID, including items, status, shipping, and tracking information. Orders are buyer-private — pass `buyer_delegation_token` (the delegation token from this buyer's checkout approval) so the gateway can confirm the buyer owns this order. If checking if an order is paid: a status of 'pending' or 'pending_payment' means the order has NOT been paid. Do NOT assume that the vendor storefront has synchronization delays or database lag; treat 'pending' as unpaid. When
List Orders — List recent orders for a site, optionally filtered by status (pending, processing, completed, cancelled, refunded). Orders are buyer-private — pass `buyer_delegation_token` (from this buyer's checkout approval); only that buyer's orders are returned.
Request Delegation — Start the human delegation (approval) flow needed for checkout/payment. PREFERRED: pass the buyer's `email` — the gateway emails them a 6-digit code and returns a device_code; ask the user for the code and call submit_delegation_otp. This keeps approval fully in-chat (no link) and you never see the code, so you cannot approve on their behalf. If you omit `email`, it falls back to a browser approval link (device flow) which the user must open; then poll check_delegation. You can never approve a d
Submit Delegation Otp — Submit the 6-digit code the buyer received by email (from request_delegation with an email) to approve the delegation in-chat. On success returns a delegation_token to use as buyer_delegation_token for checkout/payment. You cannot obtain this code yourself — the user must read it from their email and give it to you.
Check Delegation — Poll for human approval of a delegation request. When status is "approved", returns the delegation_token to use as buyer_delegation_token in execute_checkout.
Get Payment Methods — STEP 1 of the in-chat payment flow. Returns the payment channels available for an order (e.g. "mobile_money", "card") plus a `gateways` array of the enabled payment gateways (each with id, label, and its channels). When more than one gateway is listed, ask the buyer which they want to use and pass it as `gateway` to initiate_payment. Call this first, after an order exists. Then call initiate_payment with the chosen channel (and gateway if more than one). site_id falls back to DEFAULT_SITE_ID if
Initiate Payment — STEP 2 of the in-chat payment flow. Starts a payment session for an order and returns a PaymentSession with an `instruction` the agent renders in chat. REQUIRES a buyer_delegation_token — obtain it exactly like execute_checkout: call request_delegation, have the user approve in chat, then check_delegation to get the token (spending money always needs human approval). For channel "mobile_money" you MUST collect the buyer's `phone` (Ghana: 055… or +233…) and `provider` — use codes mtn, vod (Vodafo
Submit Payment Otp — STEP 3 (mobile_money only, when initiate_payment returned instruction.action == "submit_otp"). Submits the one-time password the buyer received to authorise the mobile-money charge. REQUIRES the same buyer_delegation_token used for initiate_payment. After submitting, poll get_payment_status until payment_status is "paid"/"processing" or "failed".
