Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

FAQ

Questions OpenLaws owners ask.

  • 01

    What jurisdictions are covered by OpenLaws?

    The MCP covers the US federal government, all 50 states, the District of Columbia, and Puerto Rico.

  • 02

    Can I use this with Claude or Cursor?

    Yes, this MCP is compatible with any MCP-enabled client, including Claude, Cursor, and Windsurf.

  • 03

    How does the citation validation work?

    You provide a standard legal citation, and the capability checks it for accuracy and finds the original government source.

  • 04

    Does it support state constitutions?

    Yes, you can search the US Constitution and all 50 state constitutions for specific provisions.

  • 05

    Can I see how a federal law has changed?

    Yes, the get_redline_comparison capability allows you to see changes between legislative sessions for federal statutes.

  • 06

    How do I get an OpenLaws API key and what authentication method is used?

    Visit openlaws.us/api and click Get API Access to register. Once approved, you'll receive a Bearer token. Include it in the Authorization header as Authorization: Bearer YOUR_TOKEN. The API uses standard Bearer token authentication for all v1 endpoints at https://api.openlaws.us/api/v1/.

  • 07

    Can I search statutes across all 50 states simultaneously?

    Yes! Use the search_statutes capability without specifying a jurisdiction parameter to search all 53 jurisdictions (50 states + DC + Puerto Rico + federal) at once. This is perfect for 50-state surveys. Alternatively, scope your search to a specific jurisdiction by providing its ID (e.g., 'ca' for California, 'ny' for New York, 'us' for federal).

  • 08

    How does citation validation work and what formats are supported?

    Use the validate_citation capability with any standard legal citation format. The API will identify the original government source, validate the citation accuracy, and flag malformed citations. It supports Bluebook format (e.g., '42 U.S.C. § 1983', '347 U.S. 483 (Brown v. Board)'), state citations for all 50 states, DC, and Puerto Rico. This is ideal for validating citations in legal documents, spreadsheets, and databases.

  • 09

    What legal data sources does OpenLaws cover?

    OpenLaws covers ~4.3 million tracked sections across 53 jurisdictions with 100% federal statutes and regulations coverage. Data includes: United States Code (USC), Code of Federal Regulations (CFR), all 50 state statutes and regulations, DC and Puerto Rico laws, ~5-6 million case opinions (from Harvard CAP and CourtListener), US Constitution and all 50 state constitutions, and legislative history for federal laws.
