}Side-by-side comparison of 2-5 countries: aligned rows for company count, segment mix, market-position mix, and priced market cap, plus which segments each country is uniquely present in or dominant in, and which segments they all share. country is the company's HEADQUARTERS country only, not a manufacturing-footprint field. A company headquartered here may fabricate, assemble, or test elsewhere — do not read this data as production geography.

}Structured multi-criteria screen over all 615 companies: exact segment/subsegment/country/market_position/public filters plus a market-cap range, sortable and paginated. Use this instead of search_companies when the question is a precise filter ('leader-position analog companies in Japan under $20B') rather than a free-text match. Unknown segment/subsegment/country values just return zero results rather than erroring — call get_segments or list_subsegments first if you're not sure a value is valid.
| Argument | Type | Description |
|---|---|---|
| limit | integer | Max rows to return, 1-100. Default 25. |
| offset | integer | Rows to skip, for paging past the first `limit`. Default 0. |
| public | boolean | true = only publicly traded companies, false = only private ones. Omit for both. |
| country | string | Headquarters country, exact match, case-insensitive, e.g. 'Japan'. |
| segment | string | Exact taxonomy segment id, e.g. 'foundry' (see get_segments). |
| sort_by | string | Sort field. 'market_cap' sorts descending with unpriced companies last; 'name'/'country' sort ascending. Default 'market_cap'. |
| has_ticker | boolean | true = only companies with a public ticker on file, false = only companies without one. |
Rank supply-chain chokepoints: companies many others depend on, weighted by how concentrated their market position is. A chokepoint here means high downstream dependency plus monopoly/leader position, i.e. few substitutes. Scoring is a transparent heuristic over the public dataset, not a proprietary risk model.
| Argument | Type | Description |
|---|---|---|
| limit | integer | How many to return (1-25, default 10). |
| segment | string | Restrict to one taxonomy segment id (see get_segments). |

}The shared-upstream question over a set of companies: given 2-15 company ids/tickers, or a segment id (uses every company in that segment), rank suppliers by how many of the input companies they documentedly serve (e.g. 'serves 9 of 12'), with each supplier's market position and country. Also reports how many input companies had no documented suppliers at all, since that makes a low overlap number ambiguous.
| Argument | Type | Description |
|---|---|---|
| limit | integer | Max number of ranked suppliers to return (1-100, default 20). |
| segment | string | Use every company in this taxonomy segment id instead of an explicit list (see get_segments). |

}Ranks taxonomy segments by M&A activity by mapping each deal's parties onto their companies' segments (matching by id, then falling back to case-insensitive name), then aggregating deal count and disclosed value per segment. Deals whose parties cannot be resolved to any dataset company are counted in unmapped_deals rather than dropped, so thinly-covered segments aren't silently underrepresented.
| Argument | Type | Description |
|---|---|---|
| limit | integer | How many ranked segments to return, 1-12 (there are 12 segments total). |

}
}Every M&A deal a company took part in, split by role (as acquirer, as target, or other). Matches by dataset id first, then falls back to case-insensitive name matching — necessary because a deal's target is frequently not itself a company in this dataset and carries a null id (e.g. AMD's acquisition of Xilinx lists acquirer id 'amd' but target id null, name 'Xilinx'). Each matched deal carries a match_method ('id' or 'name') so weaker name-only matches are visible to the caller.
| Argument | Type | Description |
|---|---|---|
| company* | string | Company id, exact name, or ticker to search for across all deal parties, e.g. 'amd', 'Xilinx', 'AMD'. |

}Every documented supply path between two companies, following supplier->customer edges (e.g. 'how does NVIDIA actually depend on Shin-Etsu'). Searches up to max_depth hops in one or both directions and returns each path as an ordered list of companies, shortest first. Capped for combinatorial safety; absence of a path means undocumented, not disproven — see edge_coverage.
| Argument | Type | Description |
|---|---|---|

}Nearest structural neighbours to one focal company, ranked by a transparent Jaccard-similarity score — not a market or competitive judgment. Use search_companies or resolve_ticker first if you only have a ticker or an approximate name, then pass the resolved id here.
| Argument | Type | Description |

}Screen for (customer, subsegment) pairs where the customer has exactly ONE documented supplier in that subsegment — the highest-value documented-concentration risk screen in the dataset. Optionally scoped to customers in one segment or country. Ranked by the sole supplier's downstream importance (its total documented customer count).
| Argument | Type | Description |

}For one focal company: break its suppliers down by headquarters country and by segment, report an HHI concentration index (0 = spread evenly, 1 = fully concentrated in one bucket) for each dimension, and name the single most concentrated one. Always reports supplier_edge_coverage because key_suppliers is only ~58% filled dataset-wide — a company with few listed suppliers here may be under-documented, not genuinely un-dependent. country is the company's HEADQUARTERS country only, not a manufacturing-footprint field. A company headquartered here may fabricate, assemble, or test elsewhere — do not read this data as production geography.

Use this (or get_segments) to discover valid `subsegment` values before calling get_subsegment or filter_companies. Segment/subsegment names come from a versioned taxonomy snapshot; company counts are computed live and can include subsegment ids present in the company data but not yet in that snapshot (flagged `in_taxonomy: false`).

}Batch-resolve up to 25 strings — tickers, company names, or ids, in any mix — to canonical company refs. Call this FIRST whenever you have raw user input (a ticker list, pasted names) and need valid ids before calling other tools; unresolved entries come back with up to 3 suggested close matches instead of just null.
| Argument | Type | Description |
|---|---|---|
| queries* | array | Up to 25 strings to resolve, e.g. ['NVDA', 'TSMC', 'asml']. Each may be a ticker, an exact/partial company name, or a company id. |

}Search wafergraph's semiconductor & AI supply-chain company dataset (615 companies across 12 segments) by name/one_liner substring and/or segment and/or country. Returns a compact list capped at 25 with a total match count. Use get_segments first if you don't know valid segment ids.
| Argument | Type | Description |
|---|---|---|
| query | string | Case-insensitive substring match against company name and one_liner. |
| country | string | Filter to companies headquartered in this country, e.g. 'Taiwan' (case-insensitive). |
| segment | string | Filter to companies with this taxonomy segment id, e.g. 'foundry', 'equipment_front_end' (see get_segments). |

}Remove one company, every company in one country, or every company in one segment from the documented supply graph and report the blast radius: which companies lose a documented supplier, how many alternative suppliers they retain in the same subsegment, and which are left with zero documented alternative (ranked first). This is a documented-edge simulation, not a forecast — see the caveat field.
| Argument | Type | Description |
|---|---|---|
| limit | integer | Max number of affected companies to return, zero-alternative ones first (1-100, default 20). |
| country | string | Remove every company headquartered in this country (case-insensitive exact match, e.g. 'Taiwan'). |
| segment | string | Remove every company in this taxonomy segment id (see get_segments). |
| company_id | string | Remove a single company by id, name, or ticker. Exactly one of company_id/country/segment is required. |
