How do I setup my Base64 Certificate and API credentials?

Log into your Efí account, go to **API > Applications**. Create an app to get the Client ID and Secret. Then generate a Production Certificate (`.p12`). Instead of uploading the file to Vinkius, use terminal command `base64 -i your_cert.p12` to convert it into a plaintext string, and paste that robust text directly into the MCP configuration.

Can I automatically verify if a customer paid a Pix charge just by chatting with my AI?

Yes! Provide the agent the exact transaction id (`txid`) of the generated Pix. The agent will query the `efi_get_pix_payment` tool and immediately tell you if the status is active, answered, or expired.

Does the integration support transferring money out (Cash-out)?

Yes. Using the `efi_send_pix` action, you can initiate outbound immediate payments requesting the agent to process a value directly to a receiver Pix key.

Can I query a history of paid bank slips (Boletos) at the end of the day or month?

Certainly. The `efi_list_boletos` and `efi_get_statement` tool allows you to perform large queries parsing begin/end dates to return summaries directly in your terminal.

About Efí Pay (Gerencianet) MCP Server

The Efí Pay MCP Server connects your AI agent directly to one of Brazil's largest payment and digital account platforms (formerly Gerencianet). Command your agent to handle invoicing seamlessly using natural language.

When paired with CrewAI, Efí Pay (Gerencianet) becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Efí Pay (Gerencianet) tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.

What you can do

Pix Management — Generate dynamic immediate charges (Pix Cob), check specific payment statuses in real-time, and send Pix directly to external keys.
Traditional Invoicing — Emit traditional Brazilian bank slips (Boletos) with specified expiration dates, item totals, and payer documents (CPF/CNPJ).
Account Overviews — Ask your agent to retrieve your current Efí account balance or pull a complete historical banking statement over a defined date range.

The Efí Pay (Gerencianet) MCP Server exposes 8 tools through the Vinkius. Connect it to CrewAI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use CrewAI with the Efí Pay (Gerencianet) MCP Server

CrewAI Multi-Agent Orchestration Framework provides unique advantages when paired with Efí Pay (Gerencianet) 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

Efí Pay (Gerencianet) + CrewAI Use Cases

Practical scenarios where CrewAI combined with the Efí Pay (Gerencianet) MCP Server delivers measurable value.

Automated multi-step research: a reconnaissance agent queries Efí Pay (Gerencianet) 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 Efí Pay (Gerencianet), analyzes trends over time, and generates executive briefings in markdown or PDF format

Multi-source enrichment pipelines: chain Efí Pay (Gerencianet) 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 Efí Pay (Gerencianet) against predefined policy rules, generates deviation reports, and routes findings to the appropriate team

Efí Pay (Gerencianet) + CrewAI FAQ

Common questions about integrating Efí Pay (Gerencianet) 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.
