New Relic MCP Server

A Model Context Protocol (MCP) server for querying New Relic logs using NRQL queries. This server enables Large Language Models (LLMs) like Claude to interact with your New Relic data.

Claude Code users: Also available as an installable plugin with slash commands, skills, and an investigation agent — no MCP server needed. Install with: /plugin marketplace add Ivlad003/plugins then /plugin install newrelic-observability@ivlad-plugins See Ivlad003/plugins for details.

Features

• Query New Relic logs and metrics using NRQL
• Detailed error logging
• Easy integration with Claude Desktop
• Human-readable output formatting
• Configurable New Relic account ID

Debugging

Viewing Logs

# On macOS/Linux
tail -f ~/Library/Logs/Claude/mcp-server-newrelic.log

# On Windows
type %APPDATA%\Claude\logs\mcp-server-newrelic.log

Testing with MCP Inspector

Test your server functionality using:

npx @modelcontextprotocol/inspector uv run newrelic_logs_server.py

Common Issues

1. Authentication Errors:

• Check if NEW_RELIC_API_KEY is set correctly
• Verify API key has correct permissions
• Ensure API key is valid

2. Query Errors:

• Verify NRQL syntax
• Check account ID in code matches your account
• Ensure queried data exists in the time range

3. Connection Issues:

• Check network connectivity
• Verify GraphQL endpoint is accessible
• Ensure no firewalls are blocking connections

Security Notes

• Never commit API keys to version control
• Use environment variables for sensitive data
• Keep dependencies updated
• Monitor query patterns and access logs

Development

Local Testing

1. Set environment variables:

export NEW_RELIC_API_KEY="your-api-key-here"

Setup Instructions

Prerequisites

• Python 3.10 or higher
• New Relic account and API key
• Claude Desktop application

Installation Steps

1. Install uv package manager:

# On macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# On Windows (PowerShell)
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

2. Create and setup project:

# Create directory
mkdir newrelic-mcp
cd newrelic-mcp

# Create virtual environment
uv venv

# Activate virtual environment
source .venv/bin/activate  # On Unix/macOS
.venv\Scripts\activate     # On Windows

# Install dependencies
uv pip install "mcp[cli]" httpx

3. Create server file newrelic_logs_server.py with the provided code.

4. Configure your environment variables:

# On Unix/macOS
export NEW_RELIC_API_KEY="your-api-key-here"
export NEW_RELIC_ACCOUNT_ID="your-account-id-here"

# On Windows (CMD)
set NEW_RELIC_API_KEY=your-api-key-here
set NEW_RELIC_ACCOUNT_ID=your-account-id-here

# On Windows (PowerShell)
$env:NEW_RELIC_API_KEY = "your-api-key-here"
$env:NEW_RELIC_ACCOUNT_ID = "your-account-id-here"

Claude Desktop Integration

Configure Claude Desktop by editing your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the following configuration:

{
    "mcpServers": {
        "newrelic": {
            "command": "uv",
            "args": [
                "--directory",
                "/absolute/path/to/newrelic-mcp",
                "run",
                "newrelic_logs_server.py"
            ],
            "env": {
                "NEW_RELIC_API_KEY": "your-api-key-here",
                "NEW_RELIC_ACCOUNT_ID": "your-account-id-here"
            }
        }
    }
}

Usage

Example NRQL Queries

1. Basic Transaction Query:

SELECT * FROM Transaction SINCE 1 hour ago

2. Error Analysis:

SELECT * FROM Transaction WHERE error IS TRUE SINCE 1 hour ago LIMIT 10

3. Performance Analysis:

SELECT average(duration) FROM Transaction FACET name ORDER BY average(duration) DESC LIMIT 5

Example Claude Prompts

You can ask Claude questions like:

• "Show me all transactions from the last hour"
• "Are there any errors in our application?"
• "What are our slowest endpoints?"

Troubleshooting Guide

1. Server Not Starting:

• Check Python version
• Verify all dependencies are installed
• Ensure virtual environment is activated

2. Query Not Working:

• Check logs for detailed error messages
• Verify NRQL syntax
• Ensure data exists in queried time range

3. Claude Not Connecting:

• Verify configuration file syntax
• Check paths are absolute
• Restart Claude Desktop
