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

Visit [**openlaws.us/api**](https://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/`.

Can I search statutes across all 50 states simultaneously?

Yes! Use the `search_statutes` tool 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).

How does citation validation work and what formats are supported?

Use the `validate_citation` tool 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.

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.

Why Use CrewAI with the OpenLaws MCP Server

CrewAI Multi-Agent Orchestration Framework provides unique advantages when paired with OpenLaws through the Model Context Protocol.

Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools

CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the `mcps` parameter and agents auto-discover every available tool at runtime

Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls

Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

OpenLaws + CrewAI Use Cases

Practical scenarios where CrewAI combined with the OpenLaws MCP Server delivers measurable value.

Automated multi-step research: a reconnaissance agent queries OpenLaws for raw data, then a second analyst agent cross-references findings and flags anomalies. all without human handoff

Scheduled intelligence reports: set up a crew that periodically queries OpenLaws, analyzes trends over time, and generates executive briefings in markdown or PDF format

Multi-source enrichment pipelines: chain OpenLaws tools with other MCP servers in the same crew, letting agents correlate data across multiple providers in a single workflow

Compliance and audit automation: a compliance agent queries OpenLaws against predefined policy rules, generates deviation reports, and routes findings to the appropriate team

OpenLaws + CrewAI FAQ

Common questions about integrating OpenLaws MCP Server with CrewAI.

How does CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
