What is the Upzelo MCP Server?

Connect your Upzelo churn management account to any AI agent and simplify how you retain customers and manage subscription lifecycles through natural conversation.

What you can do

  • Customer Management — List and search customer records, and update profile data for better segmentation and targeting.
  • Retention Flows — List available flows and manually trigger retention sequences for customers at risk of cancelling.
  • Subscription Tracking — Query all tracked subscriptions and update statuses or trial details programmatically.
  • Flow Monitoring — Check the real-time status and outcomes of active flow sessions to verify retention success.
  • External ID Sync — Link your internal system identifiers to Upzelo customer records for seamless integration.

How it works

1. Subscribe to this server
2. Enter your Upzelo App ID and API Key (found in your developer settings)
3. Start managing your retention strategy from Claude, Cursor, or any MCP client

Who is this for?

  • Customer Success Managers — quickly trigger retention flows and check customer health via simple AI commands.
  • Product Operations — monitor subscription statuses and sync customer data directly from the workspace.
  • Business Growth Teams — get instant insights into flow performance and active retention sessions.

Why CrewAI?

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

Can I manually start a retention flow for a customer via AI?

Yes! Use the start_flow tool and provide the Flow ID, Customer ID, and Subscription ID. This will initialize the retention experience for that user immediately.

02

How do I see if a customer successfully stayed after a flow?

Run the get_flow_session query with the specific Session ID. It will return the outcome and status of the retention attempt.

03

Is it possible to update a subscription's status via AI?

Absolutely. Use the update_subscription tool by providing the Subscription ID and the new status to synchronize data between your systems and Upzelo.

04

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.

05

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.

06

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.

07

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.

08

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.

09

MCP tools not discovered

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

10

Agent not using tools

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

11

Timeout errors

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

12

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.
