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 | $0.04729 | $0.04729 |
| Opus 5.5 | $0.01892 | $0.01892 |
| Sonnet 5.5 | $0.00946 | $0.00946 |
| Haiku 4.5 | $0.00473 | $0.00473 |
Grade C, and why
flipper-mcp AGENTS.md scanned grade C with 2 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.

AGENTS.md — Flipper MCP Server
This file provides all context an AI agent (or human developer) needs to pick up this project and continue implementation from any machine.
1. Project Overview
flipper-mcp is a Rust-based MCP (Model Context Protocol) server that runs directly on the Flipper Zero's WiFi Dev Board v1 (ESP32-S2). It exposes all default Flipper Zero applications as MCP tools over HTTP, allowing AI agents (Claude, etc.) to programmatically control a Flipper Zero over the network.
This is distinct from existing projects (e.g., busse/flipperzero-mcp) which run on a host computer. This server runs on the hardware itself.

REMOTE ACCESS:

(any machine) (outbound) (WiFi Board) (main MCU)
Data flow: MCP JSON-RPC requests arrive over HTTP at the ESP32-S2. The firmware translates them into Flipper Zero CLI commands sent over UART at 115200 baud. Responses are parsed and returned as structured JSON.
Remote access: The ESP32-S2 initiates an outbound WebSocket connection to a relay server. The relay accepts MCP HTTP requests from clients and forwards them through the WebSocket tunnel. This solves NAT traversal and unknown-IP scenarios.
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.

flipper-mcp AGENTS.md is an instructions file published in the GitHub repository roostercoopllc/flipper-mcp (31 stars, last pushed 8mo ago), licensed MIT. It adds 4,729 tokens to every session, about $0.0189 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
