Bring Pix Payments
to CrewAI
Efí Pay (Gerencianet) MCP Server · 8 tools available to AI Agents
What is the 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.
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.
How it works
1. Subscribe to this server.
2. In your Efí Back Office, generate your Client_ID, Client_Secret and .p12 Certificate.
3. Convert your .p12 certificate into a Base64 string.
4. Input the credentials in your MCP-compatible client.
Who is this for?
- SaaS Founders — quickly issue a boleto for a customer directly from your terminal or chat without opening the bank Dashboard.
- E-commerce Ops — instantly verify whether a specific Pix
txidhas been paid to fulfill an order right from your internal agent. - Financial Controllers — extract statements and daily balances dynamically to aid reconciliation.

Why CrewAI?
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.
- —
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
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.
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.
