What tools does the connector expose?
The Wizerr Claude Connector exposes five tools:
cross_reference — Find compatible alternatives for a part number
nlp_search_by_spec — Search for components using natural language specs
autocomplete_part_number — Look up part numbers by prefix
ask_part — Ask engineering questions about a component using its datasheet
get_supply_chain — Get real-time pricing, stock, and lead times from distributors
cross_reference
Searches the Wizerr XREF database for compatible alternatives to any component part number.
Inputs
part_number (required) — e.g.
LM358,TPS24701DGKlimit (optional) — Number of results to return (1–50, default 10)
Results include
Part number and manufacturer
Match type: DROP-IN, FORM FIT, or ALTERNATE
Compatibility score
Part description
Search tier: Deep Search (high confidence) or Expanded Search (broader alternates)
Example prompts
find drop-in replacements for TPS24701DGK
what can replace LM358?
find me 25 alternatives for NE555
nlp_search_by_spec
Search for components using a natural language description of your requirements. Useful when you don't have a part number but know the specs you need.
Inputs
query (required) — Natural language spec description
limit (optional) — Number of results (1–50, default 10)
manufacturers (optional) — Filter to specific manufacturers, e.g. Texas Instruments
Example prompts
find a 42V input buck converter 2A automotive temperature range
3.3V LDO 500mA SOT-23 automotive from Texas Instruments
autocomplete_part_number
Look up part numbers by prefix. Useful when you know part of a part number and want to see what's available.
Inputs
prefix (required) — Partial part number, e.g.
TPS247xref_only (optional) — Limit to parts in the XREF database only
Example prompts
search for parts starting with TPS247
ask_part
Ask engineering questions about a component. Wizerr searches its datasheet database and returns answers with page citations.
Inputs
part_numbers (required) — One or more part numbers
specs (optional) — List of specific specs to extract, e.g. input voltage range, package
question (optional) — A freeform engineering question. Use this OR specs, not both.
Example prompts
what is the operating temperature range for TPS24701DGK?
extract the input voltage range, output current, and package for LM358
get_supply_chain
Get real-time pricing, stock levels, and lead times from major distributors for any component.
Inputs
part_number (required) — The part number to look up
quantity (optional) — Quantity for price break lookup
limit (optional) — Number of distributors to return (default 10)
Example prompts
check pricing and stock for TPS24701DGK at DigiKey and Mouser
what's the lead time for LM358 at quantity 1000?
Match types explained (cross_reference)
DROP-IN — Direct replacement with same form, fit, and function
FORM FIT — Same physical form and fit, minor functional differences
ALTERNATE — Functionally similar but may require design review
Rate limits
Standard API request limits apply per user across all tool calls. Currently this is an average of 180 requests per minute (3 requests per second).
Usage limits also depend on your Wizerr plan. See the Wizerr pricing page for details.
