Gemini How It Works
Your AI agent pulls time entries from Clockify for the billing period , every tracked hour, which client, which case, which task (research, drafting, court appearance, consultation), and the duration.
It calculates totals per client: 14.5 hours on the Santos divorce at $250/hr = $3,625. It writes an itemized summary to Google Sheets: date, task description, duration, rate, and subtotal per line item.
Then it drafts a Gmail to each client with the billing summary attached as a formatted table. 'Dear Ms. Santos, please find attached your billing statement for June 2026.
Total: $3,625 for 14.5 hours across 8 billable activities. Payment is due within 30 days.' The attorney reviews the draft, clicks send.
No spreadsheet wrestling. No forgotten billable entries.
MCP Server Orchestration: 3 MCP Servers, one intelligent agent
Connect Clockify, Google Sheets and Gmail MCP servers so your AI agent reads your tracked billable hours per client and case, builds a detailed billing summary in Google Sheets, and emails the summary to each client. Attorneys who lose revenue to unbilled hours and forget to send invoices on time get a billing pipeline that runs from one conversation.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 4,700+ MCP servers and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across every tool, in one conversation. That's what this infrastructure 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 every platform.
Contextual Reasoning
Every 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 MCP servers once, and your agent handles the rest. Every time, without intervention.
Made for
exactly this
Your AI agent taps into the entire Vinkius MCP catalog to handle these for you. You describe what you need. It does the rest.

Frequently Asked Questions About This MCP Server Orchestration
Which MCP servers do I need for this workflow?
Three: Clockify, Google Sheets and Brevo. 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 that supports the Model Context Protocol works , Claude Desktop, Cursor, Windsurf, Cline and others. Connect the MCP servers and paste a prompt.
Does this replace my legal billing software?
For straightforward hourly billing, this workflow handles the time-to-invoice pipeline. For trust accounting, retainer management, and LEDES billing, dedicated legal billing software may be necessary. This workflow covers the most common scenario: tracking hours and sending statements.
Can I bill multiple rates on the same case?
If different team members track time in Clockify at different rates, the agent reads the user who logged each entry and applies their rate. Specify rates in your prompt: 'Partner at $350/hr, associate at $200/hr, paralegal at $100/hr.'
Is client data handled securely?
MCP servers authenticate through API keys. Your agent only sees Clockify workspaces, Google Sheets and Brevo accounts you have granted access to. Vinkius does not store your data.
Can I generate invoices for all clients at once?
Ask the agent to 'build billing summaries for all clients in June and draft an email for each.' It processes every client in one pass , 5 clients billed in under 3 minutes.
