Onboard Agency Clients Automatically Using MCP.
Your new client signed the contract 5 days ago and nobody has sent the onboarding questionnaire yet , the account manager forgot because they are juggling 3 other kickoffs and the client is already wondering if they made the right choice
Works with every AI agent you already use
…and any MCP-compatible client
Waiting for input…
Gemini How It Works
Your AI agent monitors HubSpot for deals that move to 'Closed Won.' When a deal closes, the agent reads the contact details and deal properties: client name, project scope, deal value, assigned AM, and start date.
Within minutes , not days , the agent triggers the onboarding sequence. Step 1: SendGrid sends a personalized welcome email from the AM with the agency's welcome template, the onboarding questionnaire link, and a request for brand guidelines, logins, and access credentials.
Step 2: The agent checks Calendly for the assigned AM's availability and includes a scheduling link for the kickoff call in the welcome email.
Step 3: If the client has not completed the questionnaire within 48 hours, SendGrid sends a gentle follow-up. The AM never forgets.
The client never waits. Onboarding time drops from 5-7 days (manual, AM-dependent) to same-day (automated, instant). The first impression is: 'We signed the contract 2 hours ago and they already sent the questionnaire.
This agency is organized.'
Connector Orchestration: 3 Connectors, one intelligent agent
Connect Calendly, HubSpot and SendGrid Connectors so your AI agent detects new client deals closed in HubSpot, sends the onboarding questionnaire and welcome sequence via SendGrid, and schedules the kickoff call through Calendly , without the account manager lifting a finger. Agencies where client onboarding is a 14-step manual checklist that depends entirely on the AM remembering to execute it , and every forgotten step delays the project start, erodes first impressions, and sets the tone for a relationship that begins with 'sorry for the delay' , get a zero-touch onboarding engine that triggers the moment the deal closes.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 5,800+ Connectors and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across all tools, in one conversation. That's what this connectivity layer was built for.
Cross-Platform Intelligence
Your agent doesn't just connect to tools. It understands the relationships between them. Data flows where it needs to go, automatically, with full context preserved across all platforms.
Contextual Reasoning
Each decision your agent makes considers the full picture. It reads CRM data, checks calendars, reviews conversation history, and acts on everything at once. Not step by step. All at once.
Productivity at Scale
What used to take 45 minutes across five different dashboards now takes one sentence. Your agent runs the entire workflow end to end while you focus on decisions that actually matter.
Zero-Config Reliability
No API keys to paste. No webhooks to configure. No YAML to debug. Connect your Connectors once, and your agent handles the rest. Each time, without intervention.
Made for

Frequently Asked Questions About This Connector Orchestration
Which Connectors do I need for this workflow?
Three: HubSpot, SendGrid and Calendly. Connect all three to your AI client before running any prompt from this page.
Does this work with Claude Desktop, Cursor or Windsurf?
Yes. Any AI client supporting the Model Context Protocol works , Claude Desktop, Cursor, Windsurf, Cline and others.
Can I customize the welcome email template?
Yes. The agent uses your SendGrid dynamic templates. Design the template in SendGrid and the agent populates it with client name, AM name, and project details from HubSpot.
Is my client data secure?
Connectors authenticate through API keys. HubSpot, SendGrid and Calendly data stays in your accounts. Vinkius does not store your client or email data.
