What is etracker-mcp CLAUDE.md?

A set of Claude Code instructions for developing and running an etracker MCP server, a service that exposes etracker reporting data to an AI assistant.

Use it when working on this Node.js and TypeScript server, including local development, builds, container images, and Helm deployments.

It keeps project structure, installation, development, build, production, Docker, and Kubernetes deployment guidance in one place.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01148	$0.01148
Opus 5.5	$0.00459	$0.00459
Sonnet 5.5	$0.00230	$0.00230
Haiku 4.5	$0.00115	$0.00115

Security

Grade A, and why

etracker-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project structure

etracker-mcp/          # repo root — Node.js/TypeScript MCP server
  src/
    index.ts           # Express app, /mcp (stateless) + /health endpoints
    auth.ts            # authMiddleware — X-Auth-Token + X-Api-Key headers
    ratelimit.ts       # Three-layer bucket rate limiter (burst / global / per-partner)
    cache.ts           # In-memory TTL cache (5 min), cache keys scoped per token
    analytics-api.ts   # etracker Reporting API client (BASE_URL: ws.etracker.com/api/v7)

Commands

# Install
npm install

# Dev (tsx, hot-reload via node --import tsx/esm)
npm run dev

# Build
npm run build        # tsc → dist/

# Production
npm start            # node --env-file=.env dist/index.js

# Docker
docker build -t etracker-mcp .
docker run -p 3000:3000 -e PARTNER_API_KEYS='{"key":"partner-a"}' etracker-mcp

# Helm
helm install etracker-mcp ./helm -f my-values.yaml

Environment variables

Variable	Required	Description
`PARTNER_API_KEYS`	yes	JSON object: `{"<key>":"<partner-id>"}` — generate keys with `openssl rand -hex 32`
`PORT`	no	HTTP port (default: 3000)
`ETRACKER_REPORT_PAGEVIEWS`	no	Override default pageviews report ID (default: `EATime`)
`ETRACKER_REPORT_CONVERSIONS`	no	Override default conversions report ID (default: `EAConversions`)
`ETRACKER_REPORT_AD`	no	Override default ad report ID (default: `EAMarketing`)

Copy .env.example to .env for local development. The etracker token is not stored in env — partners pass it per request via X-Api-Key.

Authentication model

Every request to /mcp requires two headers:

X-Auth-Token — MCP server access key (validated against PARTNER_API_KEYS, resolves to a partnerId used for rate limiting)
X-Api-Key — etracker account token (forwarded to the etracker API as X-ET-Token; never stored server-side)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
