  • Lot Traceability — Access stock lot details and batch information to maintain comprehensive quality control and compliance.
  • Order Management — Retrieve and monitor sales orders and production orders to keep your manufacturing workflow on track.
  • Stakeholder Directory — Access and manage your database of customers, vendors, and suppliers programmatically.
  • Financial Insights — Retrieve billing invoices and purchase records directly from the AI interface to monitor operational costs.
  • Resource Navigation — Explore storage locations and manufacturing formulas using natural language commands.

How it works

1. Subscribe to this server
2. Enter your Wherefour API Key and API Secret from your account settings
3. Select your environment (Production or Sandbox)
4. Start managing your ERP and inventory from Claude, Cursor, or any MCP-compatible client

Why CrewAI?

When paired with CrewAI, Wherefour becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Wherefour 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 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

FAQ

Frequently asked questions

01

How do I find my Wherefour API Key and Secret?

Log in to your Wherefour account, navigate to Settings > API, and generate a new set of credentials for your integration.

02

Can the agent check lot availability for a specific item?

Yes! Use the list_stock_lots tool to retrieve all available batches and their current quantities for any item in your catalog.

03

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.

04

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.

05

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.

06

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.

07

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.

08

MCP tools not discovered

Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.

09

Agent not using tools

Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".

10

Timeout errors

CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.

11

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.
