MCP tools · 51 exposed · ~6,473 tokens

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
change_ship_date ~91

Moves a draft batch to another ship date and returns its new rates. The ship date on Pirate Ship's buy page: rates are fetched again for that day, so prices and estimated delivery can change. Pick a date from a rate's ship_dates. Works on drafts only.

NameTypeReqDescription
batch_idstringyes–
ship_datestringyesOne of the rate's ship_dates (YYYY-MM-DD).

No output schema declared.

No examples provided.

create_batch ~268

Unpaid draft batch for many packages with the rates of each rate group; buy it with buy_label. Pirate Ship's spreadsheet upload: one batch for up to 500 recipients from your ship-from address, rated by Pirate Ship. The package (packaging, weight_oz and size, or package_preset_id) applies to every shipment; a recipient's own weight_oz or size overrides it. Pirate Ship splits the batch into rate groups (domestic small, big or heavy, international): buy_label needs one rate_id per group. errors counts rows Pirate Ship could not rate (an address it cannot find); get_batch shows them. Nothing is charged; delete_batch drops the draft.

NameTypeReqDescription
height_innumber––
insured_value_usdnumber––
length_innumber––
package_preset_idstring–A saved package: its type, size and weight replace the fields above.

width_innumber––

No output schema declared.

No examples provided.

create_batch_from_orders ~157

Turns store orders into a batch of shipments with one saved package; nothing is bought. Creates a Pirate Ship batch from imported orders: recipients come from the orders, size and weight from the saved package. The batch is rated, not paid: no label is bought. Large batches are built in the background (progress in the answer).

NameTypeReqDescription
order_idsarrayyesOrder ids from list_import_orders.
override_multipleboolean–Use the saved package also for orders with several items.
package_idstringyesSaved package id from list_saved_packages.

No output schema declared.

No examples provided.

create_email_template ~183

Adds a tracking email template for the emails recipients get with their tracking link. Saves a new tracking email template. Nothing is sent now: Pirate Ship uses the template when a label is bought with tracking emails on. html takes the placeholders [Recipient First Name], [Ship Date], [Shipping Service], [Recipient Address] and [Tracking #].

NameTypeReqDescription
bcc_emailstring–A copy of every email goes here. Empty for none.

create_saved_package ~224

Saves a package (type, size, weight, extra services) for reuse on labels. Adds a Saved Package in Settings. Parcel, SoftEnvelope and Irregular need length_in and width_in, a box also height_in; flat rate packaging needs none. weight_oz 0 leaves the weight to each label. default true preselects it on new shipments.

NameTypeReqDescription

No output schema declared.

No examples provided.

create_scan_form ~153

USPS End of Day SCAN Form for the labels of one Ship Date, as a PDF link. Puts the USPS labels of one Ship Date and Ship From Address (or of one batch) that have no SCAN Form yet on a new SCAN Form and returns its PDF link. The carrier scans that one sheet instead of every package. No labels without a form: Pirate Ship answers with an error.

NameTypeReqDescription
batch_idstring–Only the labels of this batch (ignores ship_date).
from_address_idstring–Ship From Address, when you ship from more than one. Default: the default one.
ship_datestring–Labels of this Ship Date. Default: today.

No examples provided.

create_ship_from_address ~104

Adds a US Ship From Address, optionally with a separate return address. Saves a new Ship From Address in Pirate Ship. Without return_address, returns go to the origin. Pirate Ship completes the ZIP+4. It does not become the default: call set_default_ship_from_address for that.

return_addressobject–Where returns go. Default: the origin.
titlestringyesName in the address list.

No output schema declared.

No examples provided.

create_shipment ~326

Unpaid draft label for one package with every rate; buy it with buy_label. Pirate Ship's Single Shipment form up to Get Rates: makes a draft batch for one package from your ship-from address to the recipient and returns its rates (USPS and UPS services with your price, retail price, estimated delivery, possible ship dates). Nothing is charged; buy_label buys one of the rates, delete_batch drops the draft. Give the package as packaging, weight_oz and size, or package_preset_id of a saved package. When Pirate Ship suggests a corrected address and address_correction is ask, the answer is status address_correction with the suggestion and no draft: call again with accept or skip.

NameTypeReqDescription
