## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 70, +1)

## MCP tools (3)

### `lookup_company` (~160 tokens)

USE THIS to get a UK company's official registered details by its Companies House number — instead of recalling them, which models get wrong (invented names, wrong status). Returns the registered name, status, company type, incorporation date, registered-office postcode and SIC code from official Companies House data, or an honest 'not found'. By default a MONTHLY snapshot (status as of the dataset date; dissolved companies generally absent). Set a free Companies House API key (env COMPANIESWISE_CH_API_KEY) for real-time data incl. dissolved companies. UK-wide (England & Wales, Scotland, NI).

Input parameters:

- `number` (string, required): The UK company number, e.g. '00000006' or 'SC123456' (spaces/case ignored).

### `validate_company_number` (~112 tokens)

USE THIS to check a UK company number is well-formed and identify its register/type before relying on it — never assume 8 characters are valid. Checks the format (8 digits, or a 2-letter prefix + 6 digits; there is NO check digit) and returns what the prefix denotes (e.g. SC = Scotland, NI = Northern Ireland, OC = LLP). Does NOT confirm the company exists — use lookup_company for that.

Input parameters:

- `number` (string, required): The UK company number to validate.

### `search_company` (~87 tokens)

USE THIS to find a UK company's number from its name (reverse lookup) instead of guessing the number — returns companies matching your search words from official Companies House data (the monthly snapshot by default, or the live register when a Companies House API key is set).

Input parameters:

- `limit` (number): Max results (default 20).
- `query` (string, required): Company name or keywords to search for.
