revenium-mcp 0.2.2

Model Context Protocol (MCP) server for Revenium API monitoring, analytics, and AI spending management

Revenium MCP Server

Connect AI agents to Revenium for cost tracking, alerting, and usage-based billing

Once you've connected your AI applications to Revenium using any of the supported middleware libraries or via direct API integration, this MCP server allows agents to directly interact with your Revenium account. Connect Claude, OpenAI, or any MCP-compatible AI assistant to Revenium to configure AI cost alerts & tracking as well as usage-based billing for AI products.

Features

AI Cost Tracking & Alerting - Never Be Surprised by Unexpected AI Costs Again

• Ask AI agents to set up AI cost alerts to avoid unexpected costs
• Ask AI agents to track their own costs with Revenium as they carry out actions within your application
• Ask Revenium to calculate AI cost & usage trends over time and set up alerts to immediately send slack or email notifications when anomalies occur
• Quickly investigate the reasons for AI cost spikes. Identify abnormal changes in spending by agent, API key, product, customer, and more.
• Use AI agents to integrate Revenium metering into your applications if not using Revenium's pre-built SDKs

Usage-based Billing & Chargebacks (Optional)

If or when you're ready to turn AI costs into AI revenue, the Revenium MCP will be there to help quickly make the transition.

• Ask your agent to manage all elements of usage-based billing & cost chargebacks
• Use agents to manage products, customers, subscriptions, and subscriber credentials

Profile-Based Tool Selection

The MCP provides the appropriate tools for each use case depending on your chosen startup profile:

• Starter Profile (7 tools): Cost monitoring, alerts, analytics, AI metering integration
• Business Profile (15 tools): All Starter tools plus product management, customer management, subscriptions, billing

Getting Started

For Claude Code Users (Recommended)

1. Install uv:

   pip install uv
   

2. Add to Claude Code:

   claude mcp add revenium \
     -e REVENIUM_API_KEY=hak_your_api_key_here \
     -- uvx revenium-mcp
   

Done! Claude Code will manage the configuration.

For Local Development/Testing

1. Install uv:

   pip install uv
   

2. Create .env file:

   cat > .env << EOF
   REVENIUM_API_KEY=hak_your_api_key_here
   TOOL_PROFILE=starter
   EOF
   

3. Run the server:

   uvx revenium-mcp
   

See Installation for Cursor, Augment, and other integrations.

MCP Specification

Implements Model Context Protocol version 2025-06-18.

• Framework: FastMCP 2.10+
• Transport: stdio
• Protocol: JSON-RPC 2.0

Requirements

Prerequisites

• Python 3.11+ with pip
• Your Revenium API key (get one at ai.revenium.io)
• Optional: uv/uvx for easier installation

System Requirements

• Operating System: macOS, Linux, Windows (with WSL)
• Network: Internet connection for API communication
• MCP Client: Claude Code, Cursor, Augment IDE, or any MCP-compatible client

What Gets Tracked

When you use this MCP server, the following data flows between your AI assistant and Revenium:

Data Sent to Revenium

• API requests for cost analytics and queries
• Alert configuration requests (thresholds, notifications)
• Customer/product management operations (when using Business profile)
• Transaction lookup queries

Data Retrieved from Revenium

• AI usage metrics and costs (grouped by provider, model, customer, etc.)
• Alert status and notification configurations
• Product/subscription information (Business profile)
• Analytics data and cost trends
• Anomaly detection results

Data NOT Collected

• ❌ Your AI assistant's conversations or prompts
• ❌ Prompt content (unless you explicitly submit transactions for metering)
• ❌ Personal data beyond what you configure in Revenium
• ❌ File contents or local data

Privacy & Security

• All communication uses your Revenium API key for authentication
• Data is transmitted securely over HTTPS
• API keys are never logged or exposed in tool responses
• Data handling is subject to Revenium's privacy policy

AI Query Routing (Optional Feature)

The MCP server includes an optional AI-powered query routing feature for natural language interpretation. This feature is disabled by default and is not required for normal operation.

What It Does

When enabled, the server can use OpenAI's API to interpret natural language queries and route them to appropriate tools. This is an experimental feature that adds intelligent query understanding.

Self-Metering

When AI routing is enabled, the MCP server automatically tracks its own OpenAI usage back to your Revenium account:

• Uses revenium-middleware-openai to meter its own API calls
• Creates transactions visible in your Revenium dashboard
• Provides full transparency into the MCP server's operational costs

Enabling AI Routing

AI routing is disabled by default. To enable it, add to your .env file:

# .env
REVENIUM_API_KEY=hak_your_api_key_here
OPENAI_API_KEY=sk-your_openai_key_here
AI_ROUTING_ENABLED=true
AI_MODEL_NAME=gpt-3.5-turbo  # Optional: default model

Then run:

uvx revenium-mcp

Note: Without AI routing enabled, the MCP operates normally using direct tool calls. No OpenAI API key or additional costs are required.

Environment Configuration

The MCP server uses environment variables for configuration. The method you use depends on your setup:

Setup	Method	When to Use
Claude Code	-e flag in claude mcp add	Integrating with Claude Code (most common)
Cursor/Augment	JSON config "env": {...}	Integrating with Cursor or Augment IDE
Local testing	.env file	Testing the server directly from command line

Important: Don't mix methods. Choose the one that matches your use case:

• If using Claude Code, you only need the -e flag (no .env file or export needed)
• If testing locally, use a .env file (no export needed)
• Never use export - it's session-specific and gets lost when you close the terminal

Installation

Install Python Package

Option 1: Installation with uvx (Recommended for local testing)

# Install uv if you don't have it
pip install uv

# Create .env file
cat > .env << EOF
REVENIUM_API_KEY=hak_your_api_key_here
TOOL_PROFILE=starter
EOF

# Run the server (automatically loads .env)
uvx revenium-mcp

Option 2: Package Installation in Virtual Environment

# Create and activate virtual environment
python -m venv revenium-mcp-env
source revenium-mcp-env/bin/activate  # On Windows: revenium-mcp-env\Scripts\activate

# Install package
pip install revenium-mcp

# Create .env file for configuration
cat > .env << EOF
REVENIUM_API_KEY=hak_your_api_key_here
TOOL_PROFILE=starter
EOF

# Run the server (automatically loads .env from current directory)
python -m revenium_mcp_server

Note: The .env file should be in the directory where you run the server. Never commit .env to version control.

Choose Your Profile & Start the Server

The MCP server supports two profiles to match your use case:

Profile	Tools	Target Users	Use Cases
Starter (default)	7 tools	Cost monitoring & alerts	Cost analysis, AI transaction metering
Business	15 tools	Full platform	Product & subscription management, usage-based billing, comprehensive analytics

The server uses the Starter profile by default. To use the Business profile, set the TOOL_PROFILE environment variable:

With uvx and .env file:

# Starter Profile (7 tools) - Cost monitoring, alerts, AI metering integration (default)
cat > .env << EOF
REVENIUM_API_KEY=hak_your_api_key_here
TOOL_PROFILE=starter
EOF
uvx revenium-mcp

# Business Profile (15 tools) - Usage-based billing & AI Analytics
cat > .env << EOF
REVENIUM_API_KEY=hak_your_api_key_here
TOOL_PROFILE=business
EOF
uvx revenium-mcp

For Claude Code

Choose one of the following integration methods. Both use the Starter profile by default. To use the Business profile, add -e TOOL_PROFILE=business to the command:

Option 1: Installation with uvx

# Install uv if you don't have it
pip install uv

# Starter profile (default)
claude mcp add revenium \
  -e REVENIUM_API_KEY=hak_your_api_key_here \
  -- uvx revenium-mcp

# Business profile (for advanced features)

2. System environment variables
3. Automatically loaded values from Revenium's API

Use the system_diagnostics tool to see exactly which values are being used from each source.

Common Issues

Issue: MCP server not appearing in AI assistant Solution: Verify installation with uvx revenium-mcp --version and check MCP client configuration

Issue: Authentication errors Solution: Verify API key based on your setup:

For local development (.env file):

# Check if .env exists and contains your key
cat .env | grep REVENIUM_API_KEY

# Verify the server can load it (run from project directory)
python -c "import os; from dotenv import load_dotenv; load_dotenv(); print('API Key:', os.getenv('REVENIUM_API_KEY', 'NOT FOUND')[:20] + '...')"

For Claude Code:

claude mcp list  # Verify configuration includes API key

For Cursor/Augment: Check your MCP JSON config file includes REVENIUM_API_KEY in the env section.

For any setup: Use the system_diagnostics tool to see exactly which configuration values are being used.

Issue: Tools not working as expected Solution: Check you're using the correct profile (Starter vs Business) for your use case
