Tools
1| Parameter | Type | Required | Description |
|---|---|---|---|
| city | string | No | Optional exact record-city filter, case-insensitive. Filters before pagination; does not represent service area or silently drop terms. |
| name | string | No | Business name, e.g. "Bayside Plumbing" |
| offset | integer | No | Pagination offset into the candidates list, a whole number, default 0. Each page holds up to 20 candidates; total_candidates in a candidates result is the full count. An offset past the end returns an empty candidates list with a message saying so; a negative or fractional offset returns an error. |
| license | string | No | License number, e.g. "1000002" |
| entity_id | string | No | The exact entity.id from a previous response. It selects that one record, keeping records that share a number distinct, and overrides name and license. An id no record carries, or a jurisdiction or city that is not the record's own, returns an error that names the problem. |
| jurisdiction | string | No | State or local jurisdiction: a state code ("CA" or "US-CA", any case), a full state name ("California", "District of Columbia"), or a local code such as "NYC". A state also covers the local jurisdictions inside it that the index holds (IL includes CHI, MD includes MD-HOWARD); each record states its own jurisdiction. Coverage spans dozens of US jurisdictions; a recognized place outside coverage returns jurisdiction_not_covered, and text that names no US state or local code returns an error listing the accepted forms. |

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
