The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

openstates_search_bills unknown never probed

Search state legislative bills across all covered US jurisdictions. Supports full-text search, jurisdiction/session filtering, subject tags, sponsor lookups, and sort order. Either jurisdiction or q (full-text) is required, and pairing them is the reliable form — a q-only search spans all 56 jurisdictions and exceeds the upstream timeout for a common term, though a distinctive one still returns quickly. include=sponsorships,actions returns sponsor and action history inline. sort=latest_action_desc surfaces bills currently moving. openstates_get_jurisdiction with include=legislative_sessions returns valid session identifiers for session filtering.

openstates_get_bill unknown never probed

Fetch full detail for a specific state bill. Accepts either the three-part path (jurisdiction + session + bill_id) or a direct OCD bill ID (openstates_id from search results). Use include to request votes, actions, sponsorships, documents, and versions in one call rather than searching again. include=votes returns the full vote tally and per-legislator positions. include=actions returns the complete action history. Prefer openstates_id when available to avoid session identifier lookup.

openstates_search_people unknown never probed

Search state legislators and officials by name, jurisdiction, chamber, or district, or fetch specific people by OCD person ID. Party is reported on every result but cannot be filtered on — narrow by party after the call. Either jurisdiction or id is required — a search spanning all 56 jurisdictions exceeds the upstream timeout, including a name-only one, so scope every call to a single state or to specific person IDs. Use openstates_list_jurisdictions to pick a jurisdiction, or openstates_get_legislators_by_location when you have coordinates but no state. id takes the person IDs that openstates_get_bill sponsorships and openstates_get_committee memberships hand back, and resolves any number of them in one call. Supports name substring matching (case-insensitive). org_classification targets a role type: "upper" for Senate, "lower" for House/Assembly, "executive" for governors and executive officials, and "legislature" for every legislator — both chambers merged into one paginated set (all upper members, then all lower), which excludes executive-branch officials. Omitting org_classification is not the same as "legislature": it returns every officeholder, executive officials included. include=offices adds phone, fax, and address. include=links adds website and social links.

openstates_get_legislators_by_location unknown never probed

Find every legislator representing a geographic coordinate — both tiers. Pass latitude and longitude to get the state senators and representatives for that location (and potentially governor/executive officials), plus the coordinate's two US Senators and its US Representative. jurisdiction.classification separates the tiers: "state" is a state legislature, "country" is the US Congress. current_role.org_classification does not — it is "upper"/"lower" for a US Senator exactly as for a state senator. Useful for constituent-to-representative matching, address-based policy research, and electoral boundary analysis. This server does not geocode addresses — the caller must provide decimal-degree coordinates. Use include=offices to get contact information alongside the legislator list.

openstates_search_committees unknown never probed

Experimental — Open States is actively working to restore committee support and not all states have data. Use chamber to scope to upper (senate) or lower (house) committees. Use classification=subcommittee to find subcommittees of a parent. Use include=memberships to get the full roster with member roles. The coverageNote field in the output will always note the experimental coverage limitations.

Set require_bills=true to filter to events with bills on the agenda, which is the most useful filter for tracking legislation through committee. Use include=agenda,participants for full meeting context. Empty results often indicate the state lacks event data rather than no events occurring.

openstates_list_jurisdictions unknown never probed

List all jurisdictions covered by Open States — all 50 states, DC, and 5 US territories (American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the US Virgin Islands): 56 in total, returned complete in a single default call. Returns coverage metadata: latest bill update time, latest people update time, and optionally all legislative sessions with their identifiers. Use this when you need to discover valid session identifiers for a state before calling openstates_search_bills with a session filter. The legislative_sessions include option returns all historical and current sessions — always check valid session identifiers here before using them in bill searches, since formats vary widely by state (e.g., "2025", "2025-2026", "2025rs", "2025s1").

openstates_get_jurisdiction unknown never probed

Fetch full metadata for a specific jurisdiction including all legislative sessions, their identifiers, and coverage dates. Use when you need to know the exact session identifier for a state before filtering bill searches — session formats vary widely (e.g., "2025", "2025rs", "2025s1"). Jurisdiction IDs follow OCD format: ocd-jurisdiction/country:us/state:{abbr}/government (e.g., ocd-jurisdiction/country:us/state:wa/government). State names (e.g., "Washington") and two-letter abbreviations (e.g., "wa") are also accepted.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/815483ae0cbb43c7/badge.svg)](https://brick.blue/agent/815483ae0cbb43c7)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
