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 | $0.01539 | $0.01539 |
| Opus 5 | $0.00770 | $0.00770 |
| Sonnet 5 | $0.00308 | $0.00308 |
| Haiku 4.5 | $0.00154 | $0.00154 |
Grade A, and why
espresso-mcp copilot-instructions.md scanned grade A with 1 finding 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 5d 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.

GitHub Copilot Instructions for espresso-mcp
Project Overview
This repository contains espresso-mcp, an MCP (Model Context Protocol) server for the Android Espresso testing framework. The project enables AI assistants to interact with Android devices and emulators through a standardized protocol, providing automated testing capabilities and device control.
Key Technologies
- Python 3.10+ - Core language
- FastMCP - MCP server framework
- uv - Modern Python package and project manager
- ruff - Fast Python linter and formatter
- pytest - Testing framework
- ADB (Android Debug Bridge) - Android device communication
Architecture
The project follows a clean MCP server architecture:
src/espresso_mcp/server.py- Main MCP server implementation with tools and resourcessrc/espresso_mcp/__init__.py- Package initializationtests/- Test suite using pytestpyproject.toml- Project configuration and dependenciesuv.lock- Locked dependency versions
MCP Tools Available
- Android emulator management (list, start, kill)
- Device interaction (tap, swipe, button presses)
- Text input and manipulation
- Screenshot and screen recording
- Device status and information
Development Setup
Prerequisites
- Python 3.10 or higher
- Android SDK tools (adb, emulator) for full functionality
- uv package manager
Initial Setup
# Clone and navigate to repository
git clone <repository-url>
cd espresso-mcp
# Install dependencies
uv sync --all-extras --dev
# Run the server
uv run espresso-mcp
# Or run in development mode
uv run mcp dev src/espresso_mcp/server.py
Code Style and Standards
Linting and Formatting
- Use ruff for linting and code formatting
- Configuration in
pyproject.tomlwith line length of 100 characters - Target Python 3.10+ features
- Run linting:
uv run ruff check - Fix auto-fixable issues:
uv run ruff check --fix
Code Conventions
- Follow PEP 8 style guidelines
- Use type hints for all function parameters and return values
- Document all MCP tools with clear docstrings
- Use descriptive variable and function names
- Keep functions focused and single-purpose
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.
