Sendpaper vs Warp Agent MCP
A side-by-side look at the Sendpaper and Warp Agent MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Sendpaper for delivery work over a hosted endpoint; choose Warp Agent MCP for delivery as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities
Sendpaper tools 6
get_pricingList mail products and prices (USD, printing + USPS First-Class postage included, US addresses only).create_postcardCreate a postcard order (4x6, 6x9 or 6x11) and get a payment link. Front layouts: a big headline on a color, one photo, a photo with a caption, or a collage of 2-4 photos; the back carries the message (handwriting, serif or sans) and addresses. Set express for USPS Priority Mail (2-3 days, tracked). Mails only after the user pays.create_letterCreate a printed letter order (8.5x11, mailed in a #10 envelope) and get a payment link. Either write it (content.body, up to ~3 pages, optional photo) or mail the user's own PDF (content.pdf_url, a public https link, up to 6 pages). Set certified to "certified" for USPS Certified Mail with tracking and proof of delivery, or "certified_return_receipt" to add the recipient's signature; use these when the user needs proof (tax notice replies, lease notices, disputes, demand letters). Or set express for USPS Priority Mail (not with certified). Prices: get_pricing. Mails only after the user pays.pay_orderPay for an unpaid order with a Stripe shared payment token (spt_…) the user approved, scoped to at least the order amount in USD. For an order created with recipients, this pays for the whole group at once (scope the token to batch.price). On success the order is paid and goes to print. Use only after the user approved the purchase.get_orderGet the status of a postcard or letter order by id (ord_...).cancel_orderCancel an order that has not been paid yet. Paid orders can be cancelled by emailing support before they are printed.

freight_workflowGet a ready-to-use shipment intake CSV header, results CSV header, and starter prompt for shipment quoting, weekly freight comparison, or invoice review. Guidance only: does not read files, fetch rates, schedule work, or book. Use this when an operator asks how to start or supplies invoices/a shipment sheet.compare_freight_costsCalculate USD cost differences for up to 50 distinct shipments using supplied invoice/quote amounts and explicit comparability evidence. Excludes mismatched or unknown terms, keeps losses, separates quoted opportunities from invoice differences. Does not fetch rates, verify documents, annualize savings, or book. One candidate per shipment per call.van_quoteQuote a cargo van shipment (1-3 pallets, firm price)box_truck_quoteQuote a 26' box truck shipment (1-12 pallets, firm price)ftl_quoteQuote a full truckload (53' dry van). Only origin, destination, and date required.ltl_quoteQuote an LTL shipment — returns Warp's all-inclusive rate FAST (~1-2s) so the user sees a price immediately. The inline quote card shows the Warp rate plus a 'finding other carrier rates…' loading indicator. IMMEDIATELY follow up by calling ltl_market_options with the same parameters to fill in the multi-carrier comparison (~15s). Provide dims + commodity for an exact firm quote; if you don't have dims, quote anyway — it assumes a standard 48x40x48 pallet (FAK, no freight class) for an instant price. Don't block on asking for pallet dimensions; quote first, then pass real dims for an exact rate. When a palletized load could also move by box truck or van, quote LTL alongside those and show the cheapest valid mode. Do not editorialize the results. Do not declare a winner or recommend a specific carrier. Present Warp's quote first, then list market options as context. Let the user decide.ltl_market_optionsMulti-carrier LTL comparison — returns 30+ carrier rates ranked by price (slow, ~15s). Call IMMEDIATELY AFTER ltl_quote with the same parameters; this fills in the 'finding other carrier rates…' section the fast quote card was showing. Useful when the user wants to compare carriers or pick a specific one. Do not declare a winner or recommend a specific carrier; just present the ranked list.compare_modesTHE ONE CALL for "what's the cheapest/best way to ship this?". Prices ALL FOUR freight modes (LTL / full truckload / cargo van / 26' box truck) in ONE keyless call to Warp's all-modes engine and returns a decision-complete recommendation: the winning mode, its rate, transit, a bookable quote_id, the trade-off math against the runner-up, and every mode that couldn't price (with the reason). Prefer this over calling the individual quote tools and comparing them yourself — one round trip, and modes Warp can't serve are returned as explicitly unavailable WITH the reason rather than being dropped, so there is never a silently shortened list to guess from. Dims are optional (a standard 48x40x48 pallet is assumed). Set benchmark_market:true to also rank Warp's rate against the live 30+ carrier market for the lane (adds ~15-25s) — that makes the answer decision-complete: the right mode AND whether the price is actually good. Quote-only: it never books. To book, pass the recommended quote_id to `book` after the user confirms.batch_quotePrice up to 50 lanes in one call for a specified mode per row (defaults to LTL). This returns a Warp rate per row, NOT all-mode or all-carrier comparison. For Compare All use compare_modes per shipment; for LTL carrier alternatives use ltl_market_options. Never imply this tool compared every carrier. Returns a single batch-quote card with one row per lane (origin → dest · mode · pallets · price · transit). Each priced lane keeps its quote_id and can be booked individually with book ("book row 3").bookBook a quoted shipment using any quote_id or option id returned from a quote tool (Warp or market carrier). Requires quote_id + pickup and delivery addresses. Auth required.batch_bookBook MANY already-quoted lanes in ONE call (sequential, one card charge per row). Use this after batch_quote when the user says "book all of them" or "book rows 1, 3, 5" — do NOT call book in a loop. Each row needs a quote_id (the same one batch_quote returned for that row). Pickup/delivery default to the shared addresses at the top level so a single warehouse → many destinations only needs one address pair. Returns a progress card showing per-row Booked/Failed status with tracking numbers.multistop_quoteQuote a multi-stop FTL route: ONE truck visits 3+ stops in order (first pickup → intermediate stops → final delivery). Use for milk runs, pool distribution, or multi-store replenishment on a single truck — for a simple A→B truckload use ftl_quote. Auth required (free account). Coverage is route-dependent — not every route has a rate yet.- +21 more on the listing page
