Scored across 3 tools
compare_states and get_state_requirements both retrieve compliance records, but the distinction is clear: one is explicitly for cross-state comparison, the other for a single state with optional topic narrowing. get_filing_deadlines is clearly separate. Minor risk that an agent might use compare_states for a single-state query, but descriptions mitigate.
All three tools follow a clean verb_noun pattern: compare_states, get_filing_deadlines, get_state_requirements. The verbs vary appropriately (compare vs get), and no inconsistent casing or naming styles are present.
Three tools is on the low side for a multi-state compliance domain, but each has a distinct, useful purpose. Slightly under-scoped, though still reasonable for a focused retrieval server.
The surface covers single-state requirements, deadlines, and cross-state comparison, but notably lacks a way to retrieve a complete set of requirements for a state (explicitly limited records) or federal 501c3 compliance details. These gaps may force agents to give incomplete answers for broad queries.
Available Tools
3 toolscompare_statesAInspect
The same compliance topic across several US states, for deciding where to incorporate or for an organization that operates in more than one state. Each state's records carry their own citation and verification status; a record marked review_required is unsettled and must not be presented as a settled rule. Accepts up to eight states.
Inputs: topic (required), states (required).
get_filing_deadlinesAInspect
Every requirement in one US state that has a filing deadline attached, with the deadline in plain words, the form or portal, the fee, and the official citation. Use this for 'what is due and when'. Deadlines on records marked review_required are not settled and must be shown as unconfirmed.
Inputs: state (required).
get_state_requirementsAInspect
Nonprofit compliance requirements for one US state, from 501c3.help's sourced records: formation, governance, charitable solicitation registration, reporting, tax and employment. Every record carries its official citation and a verification status. Records marked review_required are unsettled and must be presented as such, never as a settled rule. Optionally narrow by topic. Returns a limited number of records, not the whole state.
Inputs: state (required), topic.
