Can I verify if a non-profit is eligible for tax-deductible donations?

Yes! Use the `verify_charity_status` tool with the organization's EIN. Your agent will fetch the real-time compliance status from Candid's Charity Check API.

How do I find the EIN for an organization if I only have its name?

Simply ask the agent to `search_nonprofits` and provide the name. The search results will include the EIN for each matching organization, which you can then use for deeper lookups.

Does the integration allow accessing diversity and inclusion data?

Yes. Use the `get_demographics` tool. It will retrieve the DEI metadata provided by the organization to Candid, helping you understand their leadership and staff representation.

Candid (GuideStar) + CrewAI FAQ

Common questions about integrating Candid (GuideStar) 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.
