MCP New Relic Server

A Model Context Protocol (MCP) server for querying New Relic errors and metrics. This server provides tools that Claude can use to monitor and analyze application performance and errors.

Features

• Error Querying: Query application errors with customizable time ranges and filters
• Custom NRQL Queries: Execute any NRQL query directly
• Performance Metrics: Query response times, throughput, error rates, and Apdex scores
• Easy Integration: Works seamlessly with Claude Desktop and other MCP clients

Installation

Option 1: NPM Package (Recommended)

Install globally via npm:

npm install -g mcp-new-relic

Or install locally in a project:

npm install mcp-new-relic

Option 2: Docker

Pull from Docker Hub:

docker pull kivanio/mcp-new-relic

Or build locally:

git clone https://github.com/kivanio/mcp-new-relic.git
cd mcp-new-relic
docker build -t mcp-new-relic .

Option 3: From Source

1. Clone the repository:

   git clone https://github.com/kivanio/mcp-new-relic.git
   cd mcp-new-relic

2. Install dependencies:

   npm install

3. Build the TypeScript code:

   npm run build

Configuration

1. Copy .env.example to .env:

   cp .env.example .env

2. Edit .env with your New Relic credentials:

   NEW_RELIC_API_KEY=your-api-key-here
   NEW_RELIC_ACCOUNT_ID=your-account-id-here
   NEW_RELIC_REGION=US # or EU

   To get your New Relic API key:

   • Log in to New Relic
   • Go to Account Settings → API Keys
   • Create a new User Key (not an Ingest Key)

Usage with Claude Desktop

Add the server to your Claude Desktop configuration. The configuration depends on how you installed the package:

If installed via NPM globally:

1. Open Claude Desktop settings
2. Go to the "Developer" tab
3. Add to your MCP servers configuration:

{
  "mcpServers": {
    "new-relic": {
      "command": "mcp-new-relic",
      "env": {
        "NEW_RELIC_API_KEY": "your-api-key",
        "NEW_RELIC_ACCOUNT_ID": "your-account-id",
        "NEW_RELIC_REGION": "US"
      }
    }
  }
}

If installed locally or from source:

{
  "mcpServers": {
    "new-relic": {
      "command": "node",
      "args": ["/path/to/mcp-new-relic/dist/index.js"],
      "env": {
        "NEW_RELIC_API_KEY": "your-api-key",
        "NEW_RELIC_ACCOUNT_ID": "your-account-id",
        "NEW_RELIC_REGION": "US"
      }
    }
  }
}

If using Docker:

{
  "mcpServers": {
    "new-relic": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--env-file",
        "/path/to/.env",
        "kivanio/mcp-new-relic"
      ]
    }
  }
}

Using environment file:

If you have a .env file configured, you can omit the env section:

{
  "mcpServers": {
    "new-relic": {
      "command": "mcp-new-relic"
    }
  }
}

Available Tools

1. query_errors

Query application errors from New Relic.

Parameters:

• timeRange (optional): Time range for the query (default: "4 hours ago")
  • Examples: "1 hour ago", "24 hours ago", "7 days ago"
• appName (optional): Application name pattern (default: "%kivanio%")
  • Supports SQL LIKE patterns
• limit (optional): Maximum number of error types to return (default: 20, max: 100)

Example usage in Claude:

Use the New Relic tool to check for errors in the last 24 hours

2. query_custom

Execute a custom NRQL query.

Parameters:

• query (required): The NRQL query to execute

Example usage in Claude:

Run this NRQL query: SELECT count(*) FROM Transaction WHERE appName = 'kivanio-production' SINCE 1 hour ago

3. query_metrics

Query application performance metrics.

Parameters:

• timeRange (optional): Time range for the query (default: "1 hour ago")
• appName (optional): Application name pattern (default: "%kivanio%")
• metrics (optional): Array of metrics to query (default: ["response_time", "throughput", "error_rate"])
  • Available metrics: "response_time", "throughput", "error_rate", "apdex"

Example usage in Claude:

Check the performance metrics for the last 6 hours

Development

Running in development mode:

npm run dev

Building:

npm run build

Troubleshooting

Common Issues

1. Authentication errors: Ensure your API key is valid and has the necessary permissions
2. No results returned: Check that your application name pattern matches your New Relic app names
3. Connection errors: Verify your region setting (US vs EU) matches your New Relic account

Debug Mode

To see detailed logs, run the server with debug output:

DEBUG=* node dist/index.js
