What is the Metronome MCP Server?
Connect your Metronome account to any AI agent to streamline your usage-based billing and revenue operations through natural conversation.
What you can do
- Usage Ingestion & Querying — Send usage events and retrieve aggregated usage data across customers and metrics using
ingest_eventsandget_usage. - Customer Management — Create, list, and archive customers, or manage their billing configurations via
list_customersandcreate_customer. - Billing & Invoicing — Fetch, void, or regenerate invoices and track net balances with
list_invoicesandget_net_balance. - Contract Lifecycle — Create and edit contracts, manage rate cards, and track commits using
create_contractandlist_contracts. - Alerts & Monitoring — Set up notifications, alerts, and access audit logs for billing transparency.
How it works
- Subscribe to this server
- Enter your Metronome API Token
- Start managing your billing operations from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Finance Teams — reconcile usage data and manage invoices without manual exports.
- Product Managers — analyze feature usage and billing impact in real-time.
- Engineering Teams — verify event ingestion and monitor billing services directly from the terminal.

Why teams choose Vinkius for Metronome in OpenAI Agents SDK
The Metronome MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 31 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
Metronome for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Metronome MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I check the current net balance for a specific customer?
Yes! Use the get_net_balance tool with the specific customer_id to retrieve the real-time balance information.
How do I see usage broken down by specific dimensions?
You can use the get_usage_groups tool. It allows you to retrieve granular usage data for a specific customer and metric, broken down by your custom grouping dimensions.
Is it possible to list all invoices for a client to check their payment history?
Absolutely. Use the list_invoices tool and provide the customer_id to see a paginated list of all invoices associated with that account.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
