Make Parts Now: 3D Printing & CNC Machining Quotes

create_quote

Create a quote. items: [{part_id, quantity, config: {units, process, material, color, finishes, finish_color, services, infill, layer_height}}]. See get_capabilities for valid ids. Returns prices, speed options with ship/arrival dates, and next_steps.

Input Schema

Name	Required	Description
`items`	Yes	Parts to quote, each {part_id, quantity (1-100000), notes?, config: {units, process, material, color?, finishes?, finish_color?, services?, infill?, layer_height?}}
`speed`	No	Production speed: economy, standard, fast, faster, or fastest (FDM only). Faster speeds add a rush fee; get_capabilities lists each process's speeds.
`ship_to`	No	US shipping address: {name, line1, line2?, city, state, postal_code, country: 'US', phone?}
`po_number`	No	Your purchase order number, printed on the quote and order
`contact_email`	No	Email for receipts and order updates; defaults to the account email
`idempotency_key`	No	Same key on a retry returns the first result instead of creating another

Output Schema

Name	Required	Description
`id`	Yes	Quote id (qt_...)
`items`	Yes	Lines: {id, position, part, config, quantity, notes, review_status, review_note, pricing, snapshot_url, action_needed?}
`ready`	Yes	True when the quote can be paid
`speed`	No	Chosen production speed: economy, standard, fast, faster or fastest
`tiers`	No	One entry per speed: price, ship-by and arrive-by dates, eligibility
`number`	No	Quote number shown on the PDF and the website
`status`	No	open, ordered or expired (discarded or past its date)
`totals`	No	Totals for the chosen speed, including total_before_tax
`ship_to`	No	Shipping address {name, company?, line1, line2?, city, state, postal_code, country, phone?}
`blocking`	No	What stops the quote from being ready: {item_id, state, detail}
`tax_note`	No	Sales tax is added at checkout
`min_order`	No	Order minimum in dollars
`po_number`	No	Your purchase order number
`share_url`	No	The quote's page on makepartsnow.com, to show a person the parts and prices
`created_at`	No	ISO 8601
`expires_at`	No	ISO 8601. Prices hold until then; a later read re-prices at live rates
`next_steps`	Yes	Plain-English instructions for what to do next
`share_token`	No	Token of the quote's share link, {base}/quotes/share/{share_token}
`needs_review`	No	True while a part waits for manual review; payment is blocked until then
`contact_email`	No	Email for receipts and order updates
`shipping_choice`	No	Id of the chosen shipping option
`rate_set_version`	No	Version of the price list the quote was priced with
`shipping_options`	No	Carrier options for ship_to; choose one with shipping_option

TDQS

A3.6/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=false, idempotentHint=false and destructiveHint=false, so the mutation profile is covered structurally. The description adds what the call yields (prices, speed options with ship/arrival dates, next_steps), which is useful, but says nothing about auth requirements, whether the quote is persisted for later checkout, or costs (rush fees are only noted in the schema). There is a mild tension between idempotentHint=false and the presence of an idempotency_key retry mechanism, though the description itself does not contradict the annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the verb+resource in three words, followed by a compact item/config sketch and a short return summary. Dense but every clause carries information; no filler sentences.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description needn't detail return values, and annotations cover the safety profile. It supplies the payload shape and the get_capabilities prerequisite, leaving only workflow context (quote -> checkout, auth) unstated, which is a minor gap for a creation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description goes beyond the schema by enumerating the inner config keys and pointing to get_capabilities as the source of valid process/material/color ids, which is genuinely useful invocation guidance not present in the structured fields.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb+resource ('Create a quote') and then outlines the payload shape. It does not name the sibling tools (update_quote, get_quote, discard_quote) it must be distinguished from, but the core purpose is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'See get_capabilities for valid ids' gives one concrete prerequisite for constructing a valid call, and 'Returns prices, speed options... and next_steps' hints at the quoting workflow. However, there is no guidance on when to create a new quote versus updating an existing one (update_quote) or when a quote must precede checkout, so usage is only implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
