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 | $0.02567 | $0.02567 |
| Opus 5.5 | $0.01027 | $0.01027 |
| Sonnet 5.5 | $0.00513 | $0.00513 |
| Haiku 4.5 | $0.00257 | $0.00257 |
Grade A, and why
jlink_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.
How it starts
The opening of the file, as written. The whole thing — 341 lines — stays where its author put it; the contents beside it link to each section on GitHub.
JLink MCP - AI Agent 开发指南
项目概述 / Project Overview
JLink MCP 是一个基于 Model Context Protocol (MCP) 的 J-Link 调试器服务器，允许 AI 助手通过标准化接口与 J-Link 硬件调试器交互。
核心功能：
- 设备连接管理（SWD/JTAG）
- 内存读写操作
- Flash 编程（擦除/烧录/校验）
- 调试控制（暂停/运行/单步/断点）
- SVD 寄存器解析
- RTT 实时数据传输
- GDB Server 支持

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.
- 1mo ago First seen · 341 lines · 2,567 tokens per session scan A bb9f7f880d7f
jlink_mcp AGENTS.md is an instructions file published in the GitHub repository cyj0920/jlink_mcp (39 stars, last pushed 6mo ago), licensed MIT. It adds 2,567 tokens to every session, about $0.0103 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
