# Connect Metronome to Claude: Orchestrate Pricing & Contract Terms


If your team uses ChatGPT, check out our guide on [connecting Metronome to ChatGPT](https://truto.one/connect-metronome-to-chatgpt-manage-usage-customer-invoicing/) or explore our broader architectural overview on [connecting Metronome to AI Agents](https://truto.one/connect-metronome-to-ai-agents-automate-billing-approval-flows/).

If you need to connect Metronome to Claude to automate [usage-based billing operations](https://truto.one/connect-shiftcare-to-claude-sync-billing-payments-and-compliance/), orchestrate contract provisioning, query real-time spend breakdowns, or manage rate cards, you need a Model Context Protocol (MCP) server. This server acts as the translation layer between Claude's LLM function calls and Metronome's REST API. You can either build and maintain this infrastructure yourself, or use a managed [integration platform like Truto](https://truto.one/managed-mcp-for-claude-full-saas-api-access-without-security-headaches/) to dynamically generate a secure, authenticated MCP server URL.

Giving a Large Language Model (LLM) read and write access to a core financial infrastructure platform like Metronome is a severe engineering challenge. You have to handle token lifecycles securely, map dense, time-series data schemas to MCP tool definitions, and deal with strict financial data constraints. Every time Metronome updates a billing endpoint or introduces a new aggregation method, you must update your server code, redeploy, and validate the integration.

This guide breaks down exactly how to use Truto to generate a secure, managed MCP server for Metronome, connect it natively to Claude Desktop, and execute complex [RevOps and FinOps workflows](https://truto.one/connect-wix-to-claude-automate-blogs-bookings-and-messaging/) using natural language.

## The Engineering Reality of the Metronome API

A custom MCP server is a self-hosted integration layer. While the open MCP standard provides a predictable way for models to discover tools, the reality of implementing it against a specialized billing API is painful. Metronome is built to manage massive event streams, complex B2B contract negotiations, and usage-based accounting primitives. Its API reflects that complexity.

If you decide to build a custom Metronome MCP server, here are the specific integration challenges you will face:

**Idempotency and the 34-Day Ingestion Window**
When writing usage data to Metronome, you are required to handle idempotency with extreme precision. The `transaction_id` acts as a unique key for events, but Metronome strictly enforces a 34-day deduplication window. If an agent attempts to backdate an event outside this window or fails to generate a truly unique string for concurrent events, the payload drops. A custom MCP server must abstract this logic or provide strict validation constraints to the LLM to prevent silent revenue leakage.

**Time-Series Windowing and Pagination Constraints**
Extracting usage data or spend breakdowns from Metronome is not a standard CRUD list operation. You must query the data using specific time intervals (`window_size`), providing precise `starting_on` and `ending_before` timestamps. These timestamps often need to align with specific hour boundaries. If an LLM hallucinates an invalid ISO8601 string or requests an aggregation window that exceeds the endpoint's maximum allowed range, the API throws a 400 error. The MCP server must pre-process these temporal requests to ensure the LLM respects Metronome's strict time-series rules.

**Immutable Contract Structures and Rate Card Dependencies**
Contracts in Metronome are highly structured and often immutable depending on their state. You cannot simply "update" a finalized contract's core terms. Instead, you must issue an amendment that respects the original rate card dependencies, prepaid commits, and override rates. If Claude tries to apply an override rate for a product that does not exist on the base rate card, the request will fail. Your tool schemas must guide the LLM to first fetch the available rate schedule, map the correct `product_id`, and then format the amendment payload accurately.

## Generating the Metronome MCP Server

Instead of building a proxy server from scratch, handling token storage, and manually translating Metronome's OpenAPI spec into MCP JSON-RPC endpoints, you can use Truto to generate a managed MCP server.

Truto dynamically derives tool definitions from Metronome's API documentation, maintaining strict schema validations for query parameters and JSON body payloads. 

You can generate the MCP server URL through the Truto UI or programmatically via the API.

### Method 1: Via the Truto UI

1. Log into your Truto environment and navigate to the integrated accounts list.
2. Select your connected Metronome account.
3. Click the **MCP Servers** tab in the account view.
4. Click **Create MCP Server**.
5. Select your desired configuration (e.g., restrict methods to read-only, filter by specific tool tags, or set an expiration date).
6. Copy the generated MCP server URL (e.g., `https://api.truto.one/mcp/abc123xyz`).

### Method 2: Via the Truto API

For teams embedding AI capabilities into their own products, you can dynamically provision MCP servers on behalf of your users.

```typescript
// POST /integrated-account/:id/mcp
const response = await fetch('https://api.truto.one/integrated-account/METRONOME_ACCOUNT_ID/mcp', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_TRUTO_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    name: "RevOps Metronome MCP",
    config: {
      methods: ["read", "write"],
      tags: ["billing", "contracts"],
      require_api_token_auth: false
    },
    expires_at: "2026-12-31T23:59:59Z"
  })
});

const { url } = await response.json();
// Returns: https://api.truto.one/mcp/abc123xyz...
```

This generated URL contains a hashed token that authenticates the MCP connection directly to the specific Metronome tenant, mapping the API operations to MCP tools on the fly.

## Connecting the MCP Server to Claude

Once you have the Truto MCP server URL, you must register it with your Claude client. You can do this via the Claude Desktop user interface or by directly editing the configuration file.

### Method A: Via the Claude UI

If you are using a managed team environment or an application that supports UI-based connector setup:
1. Open your Claude settings.
2. Navigate to **Integrations** or **Connectors**.
3. Click **Add MCP Server**.
4. Paste the Truto MCP URL.
5. Click **Add**. Claude will perform an initialization handshake to retrieve the available Metronome tools.

### Method B: Via Manual Configuration File

For Claude Desktop, you can manually configure the server using Server-Sent Events (SSE).

1. Locate your `claude_desktop_config.json` file (typically in `~/Library/Application Support/Claude/` on macOS or `%APPDATA%\Claude\` on Windows).
2. Add the Truto MCP server URL using the `server-sse` transport:

```json
{
  "mcpServers": {
    "metronome-billing": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-sse",
        "https://api.truto.one/mcp/YOUR_GENERATED_TOKEN"
      ]
    }
  }
}
```

3. Restart Claude Desktop. You will now see the Metronome tools available in the interface.

## Security and Access Control

Giving an LLM access to billing infrastructure requires strict governance. Truto's managed MCP servers provide built-in access control primitives to restrict what the AI agent can see and do.

*   **Method Filtering:** By defining `config.methods: ["read"]`, you prevent Claude from executing state-changing operations (like voiding an invoice or amending a contract). The LLM will only see `get` and `list` operations in its tool directory.
*   **Tag Filtering:** You can restrict the server to specific operational domains. For example, setting `tags: ["invoices"]` limits the available tools to invoice endpoints, hiding contract creation or user management APIs.
*   **Time-to-Live (TTL):** The `expires_at` parameter allows you to create temporary access tokens. Once the timestamp passes, the server automatically rejects all connections, enforcing least-privilege access for temporary agent tasks.
*   **Secondary Authentication Layer:** By enabling `require_api_token_auth: true`, possession of the MCP URL is no longer sufficient. The connecting client must also provide a valid Truto API token in the Authorization header, preventing lateral movement if the URL is exposed in system logs.

## Hero Tools for Metronome

The following are the highest-leverage Metronome MCP tools. Exposing these tools gives Claude deep analytical and orchestration capabilities over your billing pipeline.

### Ingest Usage Events
`create_a_metronome_ingest`

Usage ingestion is the core of Metronome. This tool accepts an array of events (up to 100 per request) containing a `transaction_id`, `customer_id`, `event_type`, and `timestamp`. Claude can use this to backfill metered usage or construct test events during sandbox deployments.

> "Send a usage event for customer `cust_123` with event type `api_call`. Set the timestamp to the current time, and include a property `bytes_processed` with a value of 1048576."

### Retrieve Aggregated Usage Data
`get_single_metronome_usage_by_id`

Fetches batched usage data aggregated across customers and billable metrics within specific time windows. This is critical for building AI-driven spend alerts or calculating unbilled revenue mid-cycle.

> "Retrieve the hourly usage data for the `compute_seconds` billable metric across all customers for the last 24 hours."

### Create a New Contract
`create_a_metronome_contracts_create`

Provisions a new contract defining a customer's products, pricing, discounts, access duration, and billing configuration. Claude must provide the `customer_id` and the `starting_at` timestamp. This tool allows RevOps agents to seamlessly convert natural language terms into formalized billing contracts.

> "Draft a new contract for customer `cust_890` starting on the 1st of next month, linking it to the standard enterprise rate card."

### List Customer Balances
`list_all_metronome_customer_balances_lists`

Provides real-time visibility into a customer's prepaid funds and promotional credits (commits and credits). This enables Claude to instantly answer questions about remaining burn down or whether a customer has sufficient credits for an upgrade.

> "Check the current prepaid commit balance for customer `cust_456` and tell me if they are at risk of overage this month."

### Add Rates to a Rate Card
`create_a_metronome_rate_cards_add_rate`

Attaches new pricing data to an existing rate card. Claude can use this to update tier definitions, modify prorated values, or set commit rates for specific products.

> "Add a new tier to the basic rate card: charge $0.05 per API call for the first 10,000 calls, and $0.02 for any volume beyond that."

### List Invoice Spend Breakdowns
`list_all_metronome_invoices_spend_breakdowns`

Retrieves granular spend breakdowns grouped by custom dimensions (like region, user, or project). This allows Claude to generate highly specific cost analysis reports directly from billing source truth.

> "Pull the spend breakdown for customer `cust_777` for the previous billing cycle, grouped by their internal team dimension."

## Workflows in Action

When Claude is connected to Metronome via MCP, it can chain these tools together to execute complex operational workflows that normally require a human to cross-reference dashboards.

### Scenario 1: Proactive Overage Resolution

A FinOps manager asks Claude to check on a key enterprise account that is nearing the end of its billing cycle.

> "Look up customer EdgeCorp's current prepaid commit balance. If they have used more than 90% of their commit, check their daily spend breakdown for the last 7 days and summarize what product is driving the usage spike."

**Execution Steps:**
1. Claude calls `list_all_metronome_customers` filtering by the name "EdgeCorp" to resolve the `customer_id`.
2. Claude calls `list_all_metronome_customer_balances_lists` using the retrieved `customer_id` to evaluate the remaining ledger balance against the total commit amount.
3. Detecting the balance is below 10%, Claude calculates the time bounds for the last 7 days and calls `list_all_metronome_invoices_spend_breakdowns`.
4. Claude aggregates the returned line items, identifies the product ID associated with the highest spend velocity, and formats a summary report for the user.

```mermaid
sequenceDiagram
    participant User as User
    participant Claude as Claude Desktop
    participant MCP as Truto MCP Server
    participant Metronome as Metronome API
    User->>Claude: "Check EdgeCorp's commit balance..."
    Claude->>MCP: Call list_all_metronome_customers (name: EdgeCorp)
    MCP->>Metronome: GET /customers?name=EdgeCorp
    Metronome-->>MCP: Customer Data
    MCP-->>Claude: Result: cust_123
    Claude->>MCP: Call list_all_metronome_customer_balances_lists (cust_123)
    MCP->>Metronome: GET /customers/cust_123/balances
    Metronome-->>MCP: Balance Data (8% remaining)
    MCP-->>Claude: Result: 8% remaining
    Claude->>MCP: Call list_all_metronome_invoices_spend_breakdowns (cust_123, last 7 days)
    MCP->>Metronome: GET /customers/cust_123/invoices/spend_breakdowns
    Metronome-->>MCP: Spend Data
    MCP-->>Claude: Result: High compute_seconds usage
    Claude-->>User: "EdgeCorp has 8% commit remaining. The spike is driven by compute_seconds."
```

### Scenario 2: Zero-Touch Contract Provisioning

A RevOps engineer asks Claude to construct a new agreement based on a finalized sales conversation.

> "Draft a new contract for customer 'Acme Inc'. Start the contract on the first of next month. Use the standard rate card, but add a custom credit for $500 to their account to offset onboarding costs."

**Execution Steps:**
1. Claude calls `list_all_metronome_customers` to find the `customer_id` for "Acme Inc".
2. Claude calculates the ISO8601 timestamp for the first day of the upcoming month.
3. Claude calls `list_all_metronome_rate_cards_lists` to find the `rate_card_id` matching "standard".
4. Claude calls `create_a_metronome_contracts_create` passing the `customer_id`, the calculated `starting_at` date, and the `rate_card_id` to initialize the contract.
5. Claude calls `create_a_metronome_customer_credits_create` passing the `customer_id`, the $500 value, and the access schedule to finalize the onboarding allowance.

## Handling Metronome Rate Limits

When designing AI agents that query dense billing data, rate limiting is a primary architectural concern. Metronome enforces strict rate limits to protect its real-time event ingestion and aggregation engines.

It is critical to understand that **Truto does not automatically retry, throttle, or apply backoff on rate limit errors.**

When Metronome returns an HTTP 429 Too Many Requests response, Truto passes that error directly back to Claude via the MCP protocol. To aid in programmatic backoff, Truto normalizes the upstream rate limit information into standardized HTTP headers per the IETF specification:

*   `ratelimit-limit`: The maximum number of requests allowed in the current window.
*   `ratelimit-remaining`: The number of requests remaining in the current window.
*   `ratelimit-reset`: The time at which the rate limit window resets.

The caller (the AI agent framework, LangGraph orchestrator, or Claude natively) is entirely responsible for detecting the error, parsing these headers, and implementing a retry/backoff strategy (e.g., exponential backoff with jitter) before re-invoking the tool.

## Orchestrate Your Billing Operations

Building a custom integration to manage complex financial data requires extensive maintenance. Between handling timestamp constraints, managing rate card dependencies, and securing tokens, maintaining a bespoke MCP server drains engineering resources.

By leveraging Truto's managed MCP architecture, you instantly equip Claude with comprehensive, schema-validated tools for Metronome. Your AI agents can securely navigate the Metronome API out of the box, allowing your team to focus on building intelligent operational workflows rather than fighting billing infrastructure.
