google-play-analytics-mcp: Instructions file for Codex

AGENTS.md

google-play-analytics-mcp AGENTS.md is an instructions file for Codex, OpenCode from desunit/google-play-analytics-mcp. It costs 991 tokens per session, scanned A, original, MIT.

Repository instructions for an MCP server that reads Google Play Console bulk CSV reports from a Google Cloud Storage bucket and exposes analytics tools. Google Play Console is Google's dashboard for publishing and measuring Android apps.

In plain words
What is it for?
Understanding the repository, adding a new analytics report family, and testing changes.
Why use it?
They give coding agents the project rules, structure, and testing guidance needed to make safe changes without committing secrets or business data.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is desunit/google-play-analytics-mcp's own configuration. It tells Codex and OpenCode how to work on google-play-analytics-mcp itself, so it is not a mod to install elsewhere.

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.

Security

Grade A, and why

google-play-analytics-mcp AGENTS.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 1mo 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.

Guidance for AI agents (and humans) working in this repository. CLAUDE.md is a symlink to this file.

What this is

An MCP server (server.py + gp_client.py) that reads Google Play Console bulk CSV reports from a developer's Cloud Storage bucket (pubsite_prod_rev_*) and exposes them as analytics tools. Python 3.11+, stdlib + mcp, google-auth, requests. No build step; run server.py over stdio.

  • gp_client.py — auth (service-account → Storage token), bucket list/download with caching, BOM-aware decode, CSV parse, the FAMILIES spec, and aggregation helpers.
  • server.py — the FastMCP tool surface. Tools shape fetch_family() output into compact aggregated responses.

Hard rules

  1. Never commit secrets or business data. The service-account key (google-play.json / *-service-account*.json), apps.json, and the .cache/+reports/ report data are all gitignored. Before any commit, run git status and confirm none are staged. This repo is public.
  2. No org-specific values in committed code. The reports bucket, the service-account, and app aliases are supplied at runtime via env vars (GOOGLE_PLAY_REPORTS_BUCKET, GOOGLE_PLAY_SA_JSON, GOOGLE_PLAY_APP_ALIASES) or gitignored local files — never hardcoded.
  3. Read-only. The service account uses devstorage.read_only. This server must never write to the bucket or to Play Console. Don't add write scopes or mutating tools.
  4. Be honest about coverage. Google discontinued some bulk reports (retained_installers, buyers_7d after 2021-06; ratings_v2 was 2022–2023 only). Keep the desc fields and README coverage table accurate; flag historical-only families rather than implying live data.
  5. Never serve an unvalidated cache. Play rewrites the current month's file daily, so a cache keyed on filename alone silently returns a truncated month. download_object() revalidates against the object's bucket-side updated/size plus the on-disk byte length on every read; keep it that way. Any new fetch path must go through it, not a bare _request().
  6. Every response must carry coverage. fetch_family() computes data_through / days_present / missing_dates and warns on days missing inside the range; _meta() in server.py passes it through. Without it a caller comparing two windows can unknowingly compare 7 days against 4 and read a reporting hole as a real decline. Don't drop it to save tokens.

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.
