Why CrewAI?
When paired with CrewAI, Spellbook Legal AI becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Spellbook Legal AI tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
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
mcpsparameter 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

Frequently asked questions
What types of contracts can Spellbook analyze?
Spellbook can analyze a wide range of commercial contracts including NDAs, MSAs, SOWs, employment agreements, vendor agreements, customer contracts, licensing agreements, real estate contracts, and more. The AI is trained on thousands of market precedents and can identify risks, non-standard terms, and missing clauses across all common commercial contract types.
How does the market comparison feature work?
The market comparison feature compares your contract clauses against 2,000+ market precedents to show how your terms compare to market standards. It shows pro-buyer, pro-seller, and market-standard positions for each clause type, helping you understand whether your terms are favorable, aggressive, or in line with market norms.
How do I get a Spellbook API key?
Visit Spellbook.legal and sign up for an account. Navigate to Settings → Integrations or API Settings in your account dashboard to generate an API key. The key gives you access to contract analysis, clause drafting, risk detection, and market comparison features. Contact Spellbook support if you need help setting up API access.
Can Spellbook draft custom clauses for specific jurisdictions?
Yes! When drafting clauses with draft_spellbook_clause, you can specify the jurisdiction (e.g. New York, Delaware, California, UK, EU), party position (pro-buyer, pro-seller, neutral), and custom instructions. The AI generates clauses tailored to the specified jurisdiction's legal requirements and your preferred negotiating position.
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.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
