At a glance
- Runs where
- On their server. What you send to it goes to them.
- What you need
- Nothing: it answered without a login
- Tools
- 5 tools
- Its own safety labels
- 0 read-only, 5 with no label
- Memory it takes
- About 1,300 tokens of your AI's memory, just for its tool descriptions
Tokens are an estimate: the characters in its tool names, descriptions and inputs, divided by 4. The exact number depends on your AI model. Safety labels are what the server says about itself. From our latest test, 9 Nov 2026.
Is study-mcp server safe?
- None of the hidden-instruction wordings we know were found in its 5 tool descriptions.
- 0 of its 5 tools are labeled read-only; the others may change or send things.
- Overall it scored 83/100 on 9 Nov 2026.
A test can only see what the server shows from outside, not what it does with your data behind the scenes. Connect servers from makers you trust.
What this test does not check
- Its source code and packages.
- What a tool quietly does behind the scenes, such as writing a file or calling another service.
- Instructions hidden inside live tool answers. We only look for those in tool descriptions.
- Hidden instructions worded in a way our list doesn't know yet.
- Tools that could change something. Those are read, never run.

Known security advisories
It lists no public code, so there is nothing to look up in GitHub Security Advisories or OSV.dev. QAmcp tests how a server behaves. It does not scan source code.
What it can do
5 tools, in the server's own words.
balance_equation化学方程式配平：输入未配平的化学方程式（反应物=生成物，用 = 或 → 连接，物质间用 + 连接），自动用线性代数（齐次线性方程组整数解）求出最简整数系数，返回配平后的方程式、各物质系数与原子守恒校验。示例："Fe+O2=Fe3O4"、"C2H6+O2=CO2+H2O"、"KMnO4=K2MnO4+MnO2+O2"、…
element_lookup元素周期表查询（118 种元素全量本地数据）：按中文名（如 氧、铁、金）、元素符号（如 O、Fe、Au，大小写不敏感）或原子序数（1-118）查询，返回原子序数、符号、中文名、相对原子质量、族/周期、元素类别与常见化合价。不传 query 时返回全部 118 种元素。数据为本地 SQLite，无需联网。
chemistry_calc化学式摩尔质量计算：输入化学式（如 H2SO4、Ca(OH)2、Fe2(SO4)3、CuSO4·5H2O），返回摩尔质量（g/mol）、各元素的原子个数、质量贡献与质量分数（%）。支持括号嵌套与结晶水合物（用 · 连接）。放射性元素无标准原子量时会提示。
physics_calc中学物理公式计算器（力学+电学）：传入已知物理量，自动匹配公式求未知量。覆盖公式族：牛顿第二定律 F=ma（F力N/m质量kg/a加速度m/s²）、重力 G=mg（g默认9.8N/kg，可传g=10）、压强 p=F/S（Pa/N/m²）、欧姆定律 I=U/R（A/V/Ω）、电功 W=UIt（J/V/A/s）、电功率 …
math_solve中小学数学求解器，支持五类问题（结果尽量给出分数/根式精确形式+小数近似）：① kind='quadratic' 一元二次方程求根：传 expr 如 "x²-5x+6=0"、"2x^2+3x-2=0"，或系数 a,b,c（ax²+bx+c=0），返回判别式 Δ 分析（两实根/重根/无实根）与精确根、复数根提示；② k…
