Installation

Quick Install with Smithery

To install or deploy via Smithery, see the official docs: Deployments, Project Configuration, and smithery.yaml Reference.

To install New Relic MCP for Claude Desktop automatically via Smithery:

npx @smithery/cli install @cloudbring/newrelic-mcp --client claude

Smithery CLI (recommended)

We recommend the Smithery CLI for local development, inspection, and deployment flows. Benefits:

• Unified dev/build/deploy workflow, client‑agnostic
• Dev server with hot‑reload and playground (optional tunnel)
• Build bundles for stdio or shttp transports
• Inspect a server interactively; run with supplied config
• Simple install per client

Examples:

# Hot‑reload dev server
npx @smithery/cli dev src/server.ts --port 8181 --no-open

# Build production bundle (shttp transport)
npx @smithery/cli build src/server.ts --out .smithery/index.cjs --transport shttp

# Inspect a published server
npx @smithery/cli inspect @cloudbring/newrelic-mcp

# Run with config (env via JSON)
npx @smithery/cli run @cloudbring/newrelic-mcp --config '{"NEW_RELIC_API_KEY":"...","NEW_RELIC_ACCOUNT_ID":"...","NEW_RELIC_REGION":"US"}'

# Install into a specific client
npx @smithery/cli install newrelic-mcp --client claude

# Open playground
npx @smithery/cli playground --port 3001

Notes:

• This repo includes a minimal smithery.yaml with runtime: "typescript" to align with TypeScript‑first deployments.
• See the CLI reference for all commands and flags: smithery-ai/cli.

Troubleshooting

If you're having trouble connecting:

1. Verify your API key is valid:

   For US region:

   curl -X POST https://api.newrelic.com/graphql \
     -H 'Content-Type: application/json' \
     -H 'API-Key: YOUR_API_KEY' \
     -d '{"query":"{ actor { user { email } } }"}'

   For EU region:

   curl -X POST https://api.eu.newrelic.com/graphql \
     -H 'Content-Type: application/json' \
     -H 'API-Key: YOUR_API_KEY' \
     -d '{"query":"{ actor { user { email } } }"}'

2. Check that your Account ID is correct

3. Ensure your API key has the necessary permissions

4. Check the MCP client logs for detailed error messages

If you receive permission errors:

1. Verify your API key has the required permissions:

   • For NRQL queries: NRQL query permission
   • For APM data: APM read permissions
   • For alerts: Alerts read/write permissions

2. Create a new API key with broader permissions if needed

| Project | Status | Transport(s) | Deployments | APM Apps | Metrics | Alerts | Synthetics | Notes | |---------|--------|---------------|-------------|----------|---------|--------|-----------|-------| | This project (newrelic-mcp) | Active | NerdGraph + REST v2 | Create/List/Delete | List (NerdGraph + REST) | Host names + timeslices (REST) | Policies + Incidents (NG + REST) | List/Create (browser) | Comprehensive tests and docs |

Planned enhancements (based on REST v2 catalog and user demand):

• Alerts: violations and conditions management via REST where available
• Metrics: broader app‑level metrics endpoints (names/data) beyond per‑host
• Additional REST coverage: labels, key transactions, mobile apps (prioritized by feedback)
