Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| search_partsC | Search configured distributor and marketplace suppliers for engineering part candidates. |
| extract_visual_part_hintsC | Normalize image-recognition observations into searchable part hints. The MCP server does not process raw images; pass observations from Codex/Claude vision. |
| lookup_partC | Look up a known manufacturer or supplier part number. |
| compare_partsC | Compare two to ten known part numbers or candidates. |
| suggest_alternatesB | Suggest alternate parts for unavailable, costly, obsolete, or second-source needs. |

Scored across 6 tools
Each tool has a clearly distinct purpose: searching, looking up, comparing, suggesting alternatives, enriching BOM data, and extracting visual hints. No two tools perform the same function.
All tool names follow a consistent verb_noun pattern with lowercase and underscores (e.g., search_parts, lookup_part), making the naming predictable and easy to understand.
Six tools cover the core operations of a parts finder without being excessive. Each tool justifies its existence, and the set feels well-scoped for the domain.
The tool surface covers the essential workflows: discovery (search, visual hints), identification (lookup), comparison (compare, suggest alternates), and enrichment (enrich BOM). No obvious gaps for typical part-finding tasks.
