常见问题
How many parts can a single search return?
Mouser returns at most 50 records per search response. Paging is supported via `records` and `starting_record` (v1) or `records` and `page_number` (v2).
Can I place orders through this server?
No. Cart and order endpoints require an Ordering API key and are not exposed; this server covers search only.
How do I filter by RoHS or in‑stock status?
Set the `search_options` parameter to `None`, `Rohs`, `InStock`, or `RohsAndInStock`. For part‑number searches, use `part_search_options` with `None` or `Exact`.
How do I use this server with Claude Desktop?
Add an entry to your `claude_desktop_config.json` specifying the command `mouser-search-mcp` and the environment variable `MOUSER_API_KEY`. If the command is not on your `PATH`, use the absolute path to the script.
