The analyze_github_newrelic_gaps tool lets your MCP client — such as GitHub Copilot, Claude, or Cursor — read your local project files and audit your repository for missing or misconfigured New Relic instrumentation. Ask your AI assistant "Are we missing any New Relic instrumentation in this project?" and the tool scans your repository automatically.
What it checks
The tool audits four areas of your repository:
- New Relic config file: Verifies whether a valid configuration file containing an entity name exists in the repository root, and whether the entity name exactly matches the reporting entity name in New Relic.
- APM agent: Verifies whether the service actively reports data to New Relic APM and whether supported APM dependencies (Python only) are installed and linked to the repository via a
BUILT_FROMrelationship. - Browser agent: Detects whether the New Relic Browser monitoring snippet is properly embedded in your project's HTML files or page templates.
- Change Tracking: Checks whether the New Relic Change Tracking GitHub Action (
newrelic/deployment-marker-action) is included in your CI/CD workflows under.github/workflows/*.yml.
Gap states
Each monitored area reports one of four states:
| State | Meaning |
|---|---|
| Not Implemented | No instrumentation found in the repository. |
| Implemented & Working | Found and correctly configured to report to New Relic. |
| Implemented & Broken | Found instrumentation, but no matching entity name detected in New Relic, suggesting a configuration or linkage mismatch. |
| Dismissed | Previously dismissed with a dismissed label on the corresponding GitHub Issue and suppressed from repeat alerting. |
Get started
Follow these steps to enable gap analysis in your repository:
- Install the New Relic GitHub App from the GitHub Marketplace and opt in to gap analysis during setup.
- Link your APM entities to the repository by specifying
NEW_RELIC_METADATA_REPOSITORY_URLor addingrepository.urlin your New Relic config to establish aBUILT_FROMrelationship. - Ensure your MCP client has access to the New Relic MCP server. This tool requires OAuth authentication and isn't available with an API key.
Limitations
Keep the following constraints in mind when using this tool:
- Supports single-service repositories only, not monorepos with multiple services.
- Supports GitHub.com repositories only when using Autopilot.
- Detects APM instrumentation for Python only.
- Checks for the Change Tracking GitHub Action only and does not detect other deployment marker methods.
- Does not analyze Terraform, Helm, Kubernetes manifests, or mobile SDKs.
- Varies by AI model and harness.
