Vaquill MCP Server
Hosted and local MCP server over the Vaquill Developer API (US primary law: statutes, regulations, constitutions, court rules, session laws, agency guidance, plus law-change watches) with a separate mount for Indian legislation. Two mounts are deliberately disjoint: /s/_ (US) and /in/s/_ (India).
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

Connect
This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):
For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:
If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:
Tools
list_statutes_coverage— The live coverage matrix: corpus legend, per-jurisdiction counts, freshness and retrieval status. Call this before treating an empty result as an absence.get_pricing— Current credit pricing per endpoint. No auth required.list_statute_divisions— Walk the statutory hierarchy one level down. Refunded on an empty level.search_us_statutes— Hybrid semantic and keyword search across every US corpus, with filters for `corpusType`, `state`, `code`, `source`, status, year and Federal Register facets.get_us_statute_section— Section metadata by `act_id`: citation, hierarchy, breadcrumb, status and every format link.get_us_statute_section_text— Full text. Supports `format=content` (operative text only, USC), `structured=true` for a subsection tree, and `asOf` for point-in-time.get_sections_batch— Metadata for up to 50 `act_id`s in one call, with a diagnosis for each miss.resolve_statute_citation— Turn one citation string into the exact section, confirmed against the corpus.resolve_statute_citations_batch— The same verdict for up to 50 citations at once.get_section_changes— Every observed add, amend and remove for one section, cursor-paged.get_section_neighbors— The sections immediately before and after, in statutory order.get_section_cited_by— Which USC and CFR sections cross-reference this one.get_section_definitions— The defined terms from the chapter's definitions section that govern this one.get_section_cross_state— At most one comparable provision per other state, most similar first.list_session_laws— One state's session laws (acts as enacted), filtered by session, approval date or effective date. `jurisdiction` is required. An empty page is charged.get_session_law— One law's record: citation, session, dates, code sections affected, official sources and `textStatus`. Takes a `sessionLawId` or a citation (a citation adds the resolve price).get_session_law_body— The law's text exactly as printed, about 30,000 characters per page. Check `amendatoryMarkup`: if `lost`, struck language may read as law.list_boards— Every watchable board with its cadence, `lastRetrievedAt` and `retrievalStatus`.create_watch— Subscribe, repoint or pause, and remove.update_watch— Subscribe, repoint or pause, and remove.delete_watch— Subscribe, repoint or pause, and remove.list_watches— Your watches with last-notified state.test_watch— Fire a one-off `board.test` delivery.

About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
