Install the MCP server

What is MCP Integration?

Model Context Protocol (MCP) is an open protocol that allows AI assistants to connect with external tools and data sources. NOFire AI’s MCP integration brings complete production Knowledge directly into your development environment. With MCP, you can: Shift-Left (Before Deployment):

Assess deployment risk before merging code
Analyze blast radius of your changes
Identify critical services affected by your work
Get deployment strategy recommendations

Production Knowledge (Anytime):

Query production environment in natural language
Understand service dependencies and relationships
See what changed recently in any service
Investigate production behavior and incidents
Onboard new engineers by making production knowledge accessible

No dashboard switching. No context loss. All from your IDE.

Supported IDEs

NOFire AI MCP integration works with:

Cursor

Full integration with AI-powered code editor

Claude Desktop

Direct integration with Anthropic’s Claude Desktop app

MCP-Compatible Tools

Any tool supporting Model Context Protocol

Prerequisites

Before you set up the MCP integration, make sure that you have:

NOFire AI Account

You need a NOFire AI account with connected infrastructure

Data Sources Connected

Connect your observability stack (Grafana, Prometheus, Datadog), or deploy the NOFire AI Kubernetes agent, to build the production mapSetup guide

MCP API Token

Generate an MCP-specific API token from your NOFire AI dashboardAPI token guide

MCP-Compatible IDE

Install Cursor, Claude Desktop, or another MCP-compatible tool

Installation

Cursor setup

Open Cursor Settings

There are two ways to configure MCP in Cursor:Option 1: Via Cursor Settings UI

Open Cursor Settings (Cmd/Ctrl + ,)
Search for “MCP” in the settings search bar
Look for “Model Context Protocol” section
Click “Edit in mcp.json” or “Configure”

Option 2: Edit Config File DirectlyNavigate to the MCP configuration file:

macOS: ~/.cursor/mcp.json
Linux: ~/.cursor/mcp.json
Windows: %APPDATA%\.cursor\mcp.json

If the file does not exist, create it.

Add NOFire AI Configuration

Add the following configuration to your mcp.json file:

{
  "mcpServers": {
    "NOFireAI": {
      "url": "https://mcp.nofire.ai/mcp",
      "transport": "http",
      "headers": {
        "Authorization": "Bearer your-mcp-api-key-here"
      }
    }
  }
}

If you already have other MCP servers configured, add NOFire AI to the existing mcpServers object:

{
  "mcpServers": {
    "existing-server": {
      "url": "...",
      "transport": "..."
    },
    "NOFireAI": {
      "url": "https://mcp.nofire.ai/mcp",
      "transport": "http",
      "headers": {
        "Authorization": "Bearer your-mcp-api-key-here"
      }
    }
  }
}

Important: Replace your-mcp-api-key-here with your actual MCP API token from the NOFire AI dashboard.Generate your API token →

Save and Restart Cursor

Save the mcp.json file
Completely quit Cursor (File → Quit or Cmd/Ctrl + Q)
Restart Cursor

A simple window reload is not enough - you must fully quit and restart Cursor for MCP changes to take effect.

Test that NOFire AI is connected

Cursor lists the MCP servers in its AI chat panel. Make sure that NOFire AI appears there.Test the connection:Ask Cursor:

Use NOFire AI to discover services in my cluster

Or:

What's the deployment risk for my current changes using NOFire AI?

Expected behavior:

Cursor will call NOFire AI MCP server
You will see results about your services or deployment risk
If there is an error, check the troubleshooting section below

Cursor settings tips

Check MCP Status

Look for the MCP icon in Cursor’s status bar (bottom of window)
Click it to see which MCP servers are active
NOFire AI should appear in the list with a green indicator

Enable Detailed Logging To debug connection issues, enable verbose logging in Cursor settings:

Open Settings → Advanced
Enable “Developer Mode” or “Debug Logging”
Check logs in Cursor’s developer console

Claude Desktop setup

Locate Claude Desktop Config File

Find and open Claude Desktop’s MCP configuration file:macOS:

# Open in default text editor
open ~/Library/Application\ Support/Claude/claude_desktop_config.json

# Or edit with nano
nano ~/Library/Application\ Support/Claude/claude_desktop_config.json

Windows:

# Open in Notepad
notepad %APPDATA%\Claude\claude_desktop_config.json

Linux:

# Open with your preferred editor
nano ~/.config/Claude/claude_desktop_config.json

If the file does not exist, create it with an empty JSON object:

{
  "mcpServers": {}
}

Add NOFire AI Configuration

Add NOFire AI to the mcpServers section:If starting fresh:

{
  "mcpServers": {
    "NOFireAI": {
      "url": "https://mcp.nofire.ai/mcp",
      "transport": "http",
      "headers": {
        "Authorization": "Bearer your-mcp-api-key-here"
      }
    }
  }
}

If you have existing servers:

{
  "mcpServers": {
    "existing-server": {
      "command": "...",
      "args": [...]
    },
    "NOFireAI": {
      "url": "https://mcp.nofire.ai/mcp",
      "transport": "http",
      "headers": {
        "Authorization": "Bearer your-mcp-api-key-here"
      }
    }
  }
}

Important: Replace your-mcp-api-key-here with your actual MCP API token.Generate your API token →

Check the JSON syntax

Before you save, make sure that the JSON is valid:

Check that all brackets {} and braces [] are closed
Make sure that there is a comma between properties, and none after the last one
All strings must be in double quotes ""

Use a JSON validator if needed:

# On macOS/Linux, validate with Python
python3 -m json.tool ~/Library/Application\ Support/Claude/claude_desktop_config.json

Save and Restart Claude Desktop

Save the configuration file
Completely quit Claude Desktop:
- macOS: Claude → Quit Claude (or Cmd + Q)
- Windows: File → Exit
- Linux: File → Quit
Restart Claude Desktop

Claude Desktop only reads the configuration file on startup. A full restart is required.

Test that NOFire AI is available

In a new conversation with Claude, you should see MCP tools available.Test the connection:Ask Claude:

Can you use NOFire AI to discover services in my cluster?

Or:

Using NOFire AI, what's the deployment risk for changes to payment-service?

Expected behavior:

Claude will indicate it is using NOFire AI tools
You will see results from your production environment
If there is an error, see troubleshooting below

Claude Desktop settings tips

Check MCP Status

Claude shows available tools at the bottom of the chat interface
Look for indicators that NOFire AI tools are loaded
If not visible, check the developer console for errors

Enable Developer Tools To debug issues:

Open Claude Desktop Settings
Look for “Developer” or “Advanced” options
Enable developer tools/console
Check for any MCP-related errors

File Permissions Make sure that the configuration file has the correct permissions:

# macOS/Linux - make sure you own the file
chmod 644 ~/Library/Application\ Support/Claude/claude_desktop_config.json

Security considerations

MCP keys are read-only by designMCP API tokens can only query and analyze data from NOFire AI. They cannot:

Modify your production infrastructure
Trigger deployments or rollbacks
Create or delete Kubernetes resources
Change system configurations
Execute commands in your clusters

Your production environment stays safe even if an MCP key is compromised. The Kubernetes agent that observes your infrastructure state runs separately with its own authentication.
