Sos Entities MCP server

@pipeworx/sos-entities

US state business-entity registries (Secretary of State) in one normalised shape. It covers Florida, New York, Colorado, Oregon, Connecticut and Pennsylvania, plus Texas through the Comptroller's franchise-tax registrations. A record gives the entity number, legal name, type, status, formation date, principal address and registered agent, with officers given as names and roles where the state publishes them. A formation feed lists new entities in a state since a given date. Keyless.

Tools

• sossearch(name, state?, status?, limit?): finds entities by company name. It matches names that start with the query, and retries as a contains-match when nothing starts with it. Leave out state to search all seven states at once. Each state reports its own count, match and dataasof. A state whose registry failed to answer appears in stateerrors, and complete is then false.
• sosentity(state, entitynumber): returns the full record for one entity, including officers: [{name, role}] where the state publishes them. Florida gives up to six officers, Connecticut its principals, Pennsylvania all listed parties, New York the chairman or CEO, and Oregon the authorized representative. Colorado and Texas publish no officers. found: false only means the registry answered and has no such number.
• sosnewentities(state, since, namequery?, entitytype?, limit?): lists entities formed from since through today, newest first, ordered by formation date and then entity number. Future-dated (delayed-effective) filings are left out. Florida reaches back 70 days; the other states reach any date. This is the feed for new-business lists and formation monitoring.

Personal data

Bruce ruled on 2026-10-08 (decision PD, "names-and-roles") that officer, director, manager and agent names are served with their roles and source. Addresses of individuals are never served and never fetched:

• Every Socrata query names its columns.
• A person's address column is either left out of the query entirely, or wrapped in a SoQL case() that returns null unless the holder is a business.
• A registered agent's address appears only when the agent is a business.

Florida's ingest drops officer addresses at parse time. It also keeps an agent's address only when the agent is flagged as an entity and is named like one: about 37% of agents Florida flags as entities are people.

Removal requests go to hello@pipeworx.io. Names are withheld through src/removals.ts, which applies to every state.
