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

droid-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 8d 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 — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.

droid-mcp

Android MCP SDK. Exposes phone capabilities (calendar, contacts, SMS, files, media, location, sensors, camera, NFC, intents, playback, screenshot, ML Kit vision, notification reply + watch, accessibility-driven UI control, custom IME typing, floating overlay, Shizuku shell-UID admin, libsu root-UID admin, etc.) via Model Context Protocol — 145 tools across 53 modules, compatible with on-device LLMs and desktop MCP clients.

Quick Reference

  • Language: Kotlin 2.1, Android SDK 28+, Gradle 8.12
  • Build: ./gradlew assembleDebug | Test: ./gradlew :droid-mcp-core:test
  • 53 modules, 145 tools, sample app with Compose UI. Tiers 1–3 are the core surface; Tiers 4–5 (shizuku, root) are opt-in power tools excluded from :droid-mcp-all. 0.10.0 adds three opt-in hardening modules (audit, tls, server-service) — also excluded from :droid-mcp-all (they pull Room/BouncyCastle/foreground-service deps).

Key Conventions

  • Every tool implements McpTool interface: name, description, parameters, suspend fun execute()
  • Every module has a provider object (e.g. CalendarTools) with all(context), requiredPermissions(), hasPermissions(context)
  • Limit params: (params["limit"] as? Number)?.toInt()?.coerceIn(1, 100) ?: 10
  • ContentResolver queries: use ?.use { cursor -> }, NO LIMIT/OFFSET in sortOrder (handle in cursor loop)
  • File access: sandboxed via PathValidator — external storage only
  • Tool calls run on Dispatchers.IO, never main thread
  • No fully qualified names inline — use proper imports

Don't

  • Don't add LIMIT or OFFSET to ContentResolver sortOrder strings — not supported on all devices
  • Don't request permissions from library code — apps handle their own permission UX
  • Don't use SmsManager.getDefault() — use version-checked context.getSystemService() on API 31+
  • Don't require media permissions for File API access on API 33+

Architecture

Multi-module Gradle project. Each phone API is an independent module depending only on :droid-mcp-core.

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.
