Parts Sourcing

Use the bundled parts-finder MCP server for read-only sourcing work.

Workflow

1. Extract hard constraints first: part family, electrical ratings, package, connector keying, cable length, motor voltage/power, interface, temperature range, stock, price, MOQ, and compliance.
2. If a missing constraint could materially change the answer, ask one concise question. Otherwise search with explicit assumptions.
3. Prefer authorized distributors such as Mouser and DigiKey for production or reliability-sensitive recommendations.
4. Use AliExpress only when marketplace-style sourcing is appropriate, such as modules, cables, harnesses, adapters, motors, prototyping accessories, or low-cost long-tail candidates. Pass marketplaceAllowed: true explicitly.
5. Keep all actions read-only. Do not place orders, create carts, call dropshipping APIs, or mutate supplier accounts.

Tool Selection

• Use lookup_part when the user provides a likely exact MPN, supplier part number, or top marking.
• Use search_parts when the user gives a rough description, category, visual hints, or incomplete part number.
• Use compare_parts when choosing between known candidates.
• Use suggest_alternates when stock, lifecycle, price, lead time, or second-source risk is the reason for searching.
• Use enrich_bom for multiple BOM rows instead of many separate single-part calls.

Pass hard requirements into constraints rather than only putting them in free text. Useful constraints include manufacturer, mustHave, mustNotHave, inStockOnly, maxUnitPrice, maxMoq, rohsOnly, and marketplaceAllowed.

Korean field wording is acceptable for common part terms. The MCP normalizes phrases such as 2핀, 커넥터, 패널마운트, 방수, 기어모터, and 엔코더 into supplier-friendly English query variants, but exact English terms or visible markings still improve results.

If visualHints are omitted, the MCP still infers common connector and motor hints from the query text, including pin count, row count, pitch, connector family, mounting style, color, wire count, encoder, and gearhead clues.
