## MCP tools (1)

### `find_expert_witnesses` (~662 tokens)

Find Expert Witnesses in the US and Australia

Find expert witnesses and medico-legal assessors in the United States and Australia. Reads 18 public directories, merges the same person across directories into one record, and maps every source's specialty tags to one taxonomy. Each row carries name, specialty, state or region, country, firm, practice site, phone, listing URL, and the sources that list the person. Coverage is the United States and Australia only: the public actor refuses a UK or Canadian request. published_email is filled only when a source page printed an address; the actor never guesses one. Several sources restrict automated collection or solicitation in their terms; the actor README lists each source's posture, and the use decision is yours. Use it to shortlist experts by specialty and region, or run mode feed on a schedule to see new, changed, and removed listings. Requires an APIFY_TOKEN; charges per expert record, per published email, and per NPPES check, as the README pricing table lists. Writes only to the named key-value store in your own Apify account.

Input parameters:

- `country` (array): US, AU, or both. Empty returns both. United States and Australia only: the public actor refuses a UK or Canadian request and stops the run with an error, so no other value is accepted.
- `maxItems` (integer): Stop after this many output rows (one row per deduplicated expert). 0 means no cap. A capped run never marks listings as removed. Default: 100.
- `mode` (string): list returns every matching expert. feed returns only experts that are new, changed, or returned since the last run on the same persistent store, plus removed rows; unchanged experts are not emitted…
- `persistStoreName` (string): Named key-value store in your account that keeps expert records between runs. Reuse the same name for feed mode. Default: expert-witness-directory-store.
- `region` (array): State or region as the source prints it, for example Queensland, California, New South Wales. Case and accents are ignored. Empty returns every region.
- `sources` (array): Directories to read. Empty reads every implemented source. Sources that are not implemented yet, or that the actor does not cover, are skipped and named in the RUN_SUMMARY record. The 18 implemented…
- `specialty` (array): Taxonomy codes. A parent code also matches its children: medicine.psychiatry includes medicine.psychiatry.forensic. Empty returns every specialty.
- `verifyNppes` (boolean): Check each US record against the free NPPES monthly file (name, state, and specialty). Adds npi and nppes_status. NPPES carries no email. Charged per checked record. Default: false.
