## Quality 91/100 (strong)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 79 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 10 of 10 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: openstates_get_legislators_by_location (destructiveHint); openstates_get_committee (destructiveHint); openstates_search_events (destructiveHint); …
- pass `tools.token_cost`: about 5,122 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know @cyanheads/openstates-mcp-server@0.3.3, @cyanheads/openstates-mcp-server@0.3.3

- tools: 10, about 5,122 tokens to load them all
- tool set hash: 8ff778929a01c25df9548a1c58593baf
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.cyanheads/openstates-mcp-server.svg)](https://protogrid.dev/servers/io.github.cyanheads/openstates-mcp-server)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (10)

- `openstates_get_bill`: 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_get_committee`: Fetch committee detail by OCD organization ID. Returns name, classification, and membership roster when include=memberships is requested. Experimental — not all states have committee data in Open States. Obtain the committee_id from openstates_search_committees.
- `openstates_get_event`: Fetch full event detail by OCD event ID. Returns agenda, participants, media links, and associated documents when requested via include. Experimental — event coverage is limited in Open States. Obtain the event_id from openstates_search_events.
- `openstates_get_jurisdiction`: 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.
- `openstates_get_legislators_by_location`: 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_list_jurisdictions`: 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_search_bills`: 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_search_committees`: List committees for a jurisdiction. jurisdiction is required — a request spanning all 56 jurisdictions exceeds the upstream timeout, so scope every call to a single state; use openstates_list_jurisdictions to pick one. 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.
- `openstates_search_events`: Search hearings, floor sessions, and committee meetings. jurisdiction is required — the Open States events endpoint has no all-states search, so scope every call to a single state; use openstates_list_jurisdictions to pick one. Experimental — most states do not publish event data to Open States. Use after and before to scope to a date range. 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_search_people`: 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.
