How do I install Datadog?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Datadog need an API key?

No required environment variable is listed on this record.

What transport does Datadog use?

Datadog runs locally over stdio.

When was Datadog last checked?

Last checked 2026-10-28. LLM-optimized MCP server for Datadog APM, logs, and metrics. Delivers structured, token-efficient trace and log insights designed specifically for AI-driven debugging—not just raw Datadog data.

Datadog MCP-Server

Datadog Trace Diagnostic MCP Server

An MCP (Model Context Protocol) server that lets AI assistants like Claude query Datadog APM for error traces, search logs, and generate actionable debugging workflows.

Why This MCP Is Unique

Enhanced Log Summarizer

Groups similar logs → 1 compact entry
Uses advanced pattern normalization:
- <UUID>, <TS>, <IP>, <HEX>, <ID>
Adds temporal metadata (firstOccurrence, lastOccurrence)
Executes server‑side → fewer tokens, more context for LLMs

Trace Analyzer for AI Reasoning

Generates actionable diagnostic workflows
Aggregates errors per service (ServiceErrorView)
Auto-correlates logs + traces
Extracts executable test scenarios
Parses stack traces into actionable structures
Detects distributed errors automatically

Quick Install

Requirements: Java 21+, Maven 3.8+

curl -fsSL https://raw.githubusercontent.com/waabox/datadog-mcp-server/main/install.sh | bash

The installer will:

Download the stable release JAR from GitHub Releases
Copy it to ~/.claude/apps/mcp/ (removing older versions)
Register waabox-datadog-mcp as a user-scoped MCP server in ~/.claude.json
Ask for your Datadog API keys (optional; on upgrade, existing keys are kept)

  "totalDurationMs": 1240
}

Workflow: From Trace to Unit Test

1. User: "Extract scenario from trace abc123 in order-service"

2. Claude analyzes the trace and responds:
   "Based on the trace, here's what happened:

   Entry Point: POST /api/orders with body {"product_id": "123", "quantity": 5}

   Execution Flow:
   1. api-gateway → POST /api/orders (1240ms)
   2. order-service → OrderController.createOrder (1100ms)
   3. order-service → SELECT * FROM products WHERE id = ? (45ms)
   4. order-service → OrderService.validateStock ❌ (12ms)

   Error: InsufficientStockException at OrderService.java:142
   Message: 'Not enough stock: requested 5, available 2'

   Where is the order-service codebase? I can look at the code and suggest a unit test."

3. User provides codebase path

4. Claude reads the code and proposes:
   "@Test
   void whenValidatingStock_givenQuantityExceedsAvailable_shouldThrowException() {
       // Given
       Product product = new Product("123", "Test Product", 2);
       OrderRequest request = new OrderRequest("123", 5);

       // When / Then
       InsufficientStockException ex = assertThrows(
           InsufficientStockException.class,
           () -> orderService.validateStock(request, product)
       );

       assertEquals("Not enough stock: requested 5, available 2", ex.getMessage());
   }"

4. Search Logs (`log.search_logs`)

Search for logs with various filters and optional pattern summarization.

Natural Language Prompts:

"Search ERROR logs in payment-service from the last hour"

"Find all logs mentioning 'timeout' in order-service today"

"Show me WARNING and ERROR logs in api-gateway between 2pm and 4pm"

"Summarize the log patterns in notification-service from yesterday"

  },
  "degraded": true,
  "signals": ["error rate 0.17% -> 2.83%"],
  "notes": []
}

7. APM Top Resources (`apm.top_resources`)

Rank a service's resources (endpoints) by errors, error rate, latency, or traffic.

Natural Language Prompts:

"What are the top failing endpoints in payment-service over the last hour?"

"Which checkout-service endpoints get the most traffic?"

Parameters:

param	type	required	default	notes
`service`	string	yes
`env`	string	no	`DATADOG_ENV_DEFAULT`
`from`	ISO-8601	yes
`to`	ISO-8601	yes
`operation`	string	no	detected (BR-3)

  "operationSource": "detected",
  "window": {"from": "...", "to": "..."},
  "sortBy": "errors",
  "count": 1,
  "resources": [
    {"resource": "post_/api/checkout", "hits": 4200, "errors": 310, "errorRate": 7.38,
     "latencyP50": 120.0, "latencyP95": 850.0, "latencyP99": 2100.0}
  ],
  "notes": []
}

The API key and application key need the timeseries_query permission in addition to the current APM and logs read permissions.

Resource names in apm.top_resources come from trace metrics, where Datadog normalizes tag values: lowercase, with spaces and braces replaced by _. For example, GET /presales/{eventCode}/validate is returned as get_/presales/_eventcode_/validate. Translate it back before using it in span or log searches.

Common Workflows

Debugging a Production Incident

1. "List error traces for payment-service from the last 30 minutes"
   → Identifies recent errors and their trace IDs

2. "Inspect trace abc123 in payment-service from the last hour"
   → Gets full diagnostic with spans, logs, and workflow

3. "Correlate logs for trace abc123 in payment-service"
   → Shows all logs associated with this specific request

Investigating Intermittent Errors

1. "Search ERROR logs in order-service from today, summarize patterns"
   → Groups similar errors to identify patterns

2. "List error traces for order-service from the last 6 hours with limit 50"
   → Gets more traces to analyze the pattern

3. "Inspect trace xyz789 in order-service"
   → Deep dive into a specific occurrence

Cross-Service Error Analysis

1. "Inspect trace abc123 in api-gateway from the last hour"
   → Shows all services involved in the distributed trace

2. "Search ERROR logs in downstream-service with query 'trace_id:abc123'"
   → Finds related errors in downstream services

Datadog Permissions Required

Endpoint	Permission
`POST /api/v2/spans/events/search`	`apm_read`
`GET /api/v1/trace/{traceId}`	`apm_read`
`POST /api/v2/logs/events/search`	`logs_read_data`
`POST /api/v2/query/scalar`	`timeseries_query`

Creating Your Datadog Keys

You need two keys from Datadog: an API Key and an Application Key.

Step 1: Get Your API Key

Log in to Datadog
Go to Organization Settings (bottom-left menu)
Navigate to ACCESS → API Keys
Click + New Key
Give it a name (e.g., MCP Server)
Copy the key value (32-character hex string like abcd1234abcd1234abcd1234abcd1234)

Note: The API Key is different from the Key ID. Copy the actual key value, not the UUID.

Step 2: Get Your Application Key

In Organization Settings, go to ACCESS → Application Keys
Click + New Key
Give it a name (e.g., MCP Server)
Important: Configure the required scopes:
- apm_read - Read APM traces and spans
- logs_read_data - Read log data
- timeseries_query - Query APM trace metrics (apm.service_health, apm.top_resources)
Copy the key value (40-character string like abcd1234abcd1234abcd1234abcd1234abcd1234)

Note: Copy the actual key value from the KEY column, not the Key ID.

Step 3: Configure Environment Variables

Set these in your MCP configuration:

Variable	Description	Example
`DATADOG_API_KEY`	Your API Key (32 chars)	`abcd1234abcd1234abcd1234abcd1234`
`DATADOG_APP_KEY`	Your Application Key (40 chars)	`abcd1234abcd1234abcd1234abcd1234abcd1234`
`DATADOG_SITE`	Your Datadog site (optional)	`datadoghq.com`

Installation

Build from Source

git clone https://github.com/waabox/datadog-mcp-server.git
cd datadog-mcp-server
mvn clean package

The JAR appears in:

target/datadog-mcp-server-1.3.0.jar

MCP Configuration (Claude Code)

Add this to your ~/.claude.json:

{
  "mcpServers": {
    "waabox-datadog-mcp": {
      "command": "java",
      "args": ["-jar", "/Users/YOUR_USER/.claude/apps/mcp/datadog-mcp-server.jar"],
      "env": {
        "DATADOG_API_KEY": "your-api-key-here",
        "DATADOG_APP_KEY": "your-app-key-here",
        "DATADOG_SITE": "datadoghq.com"
      }
    }
  }
}

Replace YOUR_USER with your username and update the keys with your actual Datadog credentials.

Docker Setup

You can run the MCP server as a Docker container, which removes the need for a local Java installation.

1. Build the image

git clone https://github.com/waabox/datadog-mcp-server.git
cd datadog-mcp-server
docker build -t datadog-mcp-server .

2. Configure Claude Code

{
  "mcpServers": {
    "waabox-datadog-mcp": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--env", "DATADOG_API_KEY=your-api-key-here",
        "--env", "DATADOG_APP_KEY=your-app-key-here",
        "--env", "DATADOG_SITE=datadoghq.com",
        "datadog-mcp-server"
      ]
    }
  }
}

Replace the key values with your actual Datadog credentials.

Rebuilding after updates
