What is analytics-mcp CLAUDE.md?

Project instructions for analytics-mcp, an open-source server that provides tools for reading data from services such as Google Analytics, Cloudflare, Vercel, and Google Search Console.

They help developers change adapters and tools safely, test real API response shapes, keep environment-specific code isolated, and avoid exposing credentials or customer identifiers.

They enforce boundaries around customer configuration, API response inspection, server design, and secret handling before structural changes are made.

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	$0.00637	$0.00637
Opus 5.5	$0.00255	$0.00255
Sonnet 5.5	$0.00127	$0.00127
Haiku 4.5	$0.00064	$0.00064

Security

Grade A, and why

analytics-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 2mo ago.

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.

How it starts

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — analytics-mcp

Open-source unified web-analytics MCP server (GA4 + Cloudflare + Vercel + GSC). Read SPEC.md before changing anything structural.

Non-negotiable rules

The org decoupling. No organization name, property id, zone id, domain or token appears in code, tests, fixtures or docs — ever. Business use is pure configuration (SITES_CONFIG + env). Fixtures use fictitious ids.
Probe before typing. No adapter or tool is typed against a guessed response shape. Run pnpm probe (F1+), read the capture in scratch/, type against that. This repo inherits the rule from PowerAutomate_mcp and it applies even to documented APIs — docs drift, captures don't.
The seam stays clean. createServer() imports nothing from Vercel/HTTP/stdio. Environment switching lives only in entry points (api/mcp.ts, src/index.ts, src/serve.ts) and sources/registry.ts. An environment if inside a tool is a bug, not a shortcut.
Secrets never transit tool output. list_sources reports presence (configured: true), never values. Upstream error bodies are truncated; auth headers are never echoed.

Conventions (inherited from PowerAutomate_mcp)

ESM (NodeNext), strict, single quotes, semicolons, printWidth 100.
One tool per file in src/tools/, exporting xSchema (zod) + handleX.
All tools read-only in v1; every handler routes through runTool.
pnpm verify = check + lint + format:check + test + gates. Run before calling any phase done.

Phase gates

pnpm gates builds and runs tests/gates/ against dist/ — small security + performance suites that grow per phase (see SPEC.md § Phase gates). They spawn the compiled server; they are excluded from pnpm test.

Scope

In v1: read-only analytics across the 4 sources, normalized query, raw escape hatch, OAuth 2.1 remote + stdio local. Out: writes of any kind, multi-tenant auth, the mcp-subprocess adapter (interface exists, no impl).

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.
