FAQs on using Merge's Datadog MCP server

What is a Datadog MCP server?

It’s a server that exposes data and functionality from Datadog through tools. Your agents can use these tools to update dashboards, cancel a scheduled downtime, fetch APM services, and more.

How can I use the Datadog MCP server?

Here are just a few use cases (these use cases can also apply to other observability MCP servers):

Incident detection and triage: Your agent can monitor Datadog alerts and service health, and if an incident occurs, automatically open an incident with a short triage summary. For example, when an API latency monitor fires, it can pull affected endpoints, recent deploys, and related logs or traces
Alert noise reduction and routing: Your agent can detect duplicate or flapping alerts and recommend better thresholds or routing. For instance, it can route low-severity alerts to Slack while reserving paging for sustained issues
Root cause investigation across signals: Your agent can correlate metrics, logs, and traces to build a timeline from an alert. For example, when error rates spike, it can surface the services, regions, and log patterns most strongly associated with the issue
SLO and reliability reporting: Your agent can track SLO performance and generate regular summaries. For example, it can report weekly SLO attainment, error budget burn, and the incidents that had the biggest impact
Deployment health monitoring: Your agent can watch key metrics during deploys and flag regressions. For example, if a canary release increases 5xx errors, it can notify the on-call engineer with supporting charts and traces
Cost and usage optimization: Your agent can spot unexpected growth in logs, metrics, or APM usage. For example, it can identify a noisy service driving up log volume and suggest sampling or exclusion rules

What makes Merge Agent Handler’s Datadog MCP server better than alternative Datadog MCP servers?

Merge Agent Handler differentiates itself at the platform layer:

Enterprise-grade security and DLP: All tool inputs and outputs are scanned by a security gateway with configurable data-loss-prevention rules, allowing sensitive data to be blocked, redacted, or logged based on policy
Real-time observability and auditability: Every tool call to Datadog’s MCP server is logged with a fully-searchable audit trail, enabling teams to monitor, debug, and review agent behavior across production environments
Managed authentication and permissions: Agent Handler handles credential storage, dynamic authorization flows, and shared vs. individual authentication without requiring custom infrastructure
Evaluation suite: Pressure test the Datadog connector with automated evaluations to ensure high-quality, consistent tool call performance

Can I set custom security rules for Datadog tool calls in Merge Agent Handler?

Yes, Merge Agent Handler supports custom security rules through its Security Gateway and Data Loss Protection (DLP) system. These rules can inspect both tool inputs and outputs and automatically block, redact, or mask sensitive data before it is returned to the agent.

Here are just a few examples:

API keys and tokens: Block any tool calls that attempt to include API keys, authentication tokens, or credentials in Datadog monitor configurations, dashboard annotations, or incident notes
Internal service identifiers: Redact sensitive internal service names or infrastructure identifiers from Datadog query results, so agents only see masked versions (e.g., prod-*-db) when retrieving metrics or logs
Customer data in logs: Prevent agents from creating or updating Datadog log queries that expose customer PII, email addresses, or account numbers by blocking tool calls containing these patterns
Social security numbers: Block any tool calls that attempt to include SSNs in Datadog incident descriptions, dashboard text, or monitor messages before they're written to your observability platform
External alert destinations: Block tool calls that attempt to configure Datadog monitors or incidents with webhook destinations outside your organization's approved domains
Credit card numbers: Automatically block any attempts to log or query credit card information through Datadog's logging or APM tools

How can I start using Merge Agent Handler’s Datadog MCP server?

You can follow these steps:

1. Create your Agent Handler account. Sign up for a free account here.

2. Create a Tool Pack. Navigate to "Tool Packs" in the left sidebar and click "Create New Tool Pack." Give it a descriptive name (e.g., "Datadog Monitoring Pack").

3. Add the Datadog connector. Browse the available connectors and add Datadog to your Tool Pack.

4. Configure authentication. Choose your authentication method:

Individual authentication: Each user connects their own Datadog account
Shared authentication: Use one set of organization-level credentials for all users

5. Select specific tools.Choose which Datadog tools you want to make available to your agent, or enable all tools by default.

6. Register a User. Navigate to "Registered Users" in the sidebar and create a new registered user. This represents the identity that will perform actions through your agent.

7. Save your Tool Pack. Review and save all your Tool Pack settings.

8. Connect to your agent or IDE. Copy the MCP entry URL from your Tool Pack settings and add it to your IDE's MCP configuration file (e.g., mcp.json for Cursor or the MCP settings for Windsurf/Claude Desktop). Include your API key in the authorization header. After restarting your IDE or agent, you'll have access to all the Datadog tools you configured.
