What is vision-mcp AGENTS.md?

Project instructions for vision-mcp, a tool that lets text-only coding agents use images through a command-line program and MCP server. It covers the project structure, commands, user flows, and constraints.

Use it when developing vision-mcp, especially for its clipboard-based image input, image-to-text chat handling, configuration, commands, and tests.

It gives an agent clear rules for changing and testing the project without adding unrelated features or exposing API keys.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00427	$0.00427
Opus 5.5	$0.00171	$0.00171
Sonnet 5.5	$0.00085	$0.00085
Haiku 4.5	$0.00043	$0.00043

Security

Grade A, and why

vision-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 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.

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.

What it actually says

vision

给纯文本模型补视觉。引擎是 Node CLI vision，MCP / Skill / dsh 插件都 spawn 它。

结构

bin/vision.js        # 入口：vision add|see|install|mcp|...
lib/                 # config / engine / install / mcp / cli
dsh/                 # DeepSeek Harness 插件：工具 + 聊天框图片拦截
skills/vision-see/   # 教 agent 何时看图、如何 添加/删除/切换/启用/关闭
tests/               # node --test，不打真实视觉 API

配置只住 ~/.vision-mcp/config.json
视觉请求走 OpenAI-compatible /v1/chat/completions
默认图源是系统剪贴板
stdout：CLI 结果或 MCP JSON-RPC；日志打 stderr
dsh 聊天框附图：插件在 llm/stream 把图转成文字再交给当前文本模型；会话里仍显示原图
不写 Python。安装用 npm

用户路径

npm i -g github:hal666/vision-mcp
vision install

然后在 agent 里说「添加」给 model + apikey，或直接：

vision add <model> <apikey>

Agent 输入框：/vision add /vision delete /vision switch /vision enable /vision disable /vision see

终端：vision add 等同，没有 /。

命令

npm install
npm test
node bin/vision.js doctor

改完必须跑 npm test 和 node bin/vision.js doctor。

约束

不删用户数据、不改系统配置、不装无关全局包
不写 Playwright / HTML / 网页抓取
换规范先改本文件，再改代码

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.
