About Abacus MCP Server

Abacus MCP Server is an MCP server published by iflow-mcp in the Developer Tools category: aBACUS, an open-source DFT-based simulation platform, is supported by an MCP server that provides a structured communication interface for submitting, managing, and executing tasks.

Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

Install

From source
git clone https://github.com/iflow-mcp/abacus-mcp-server

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

结构优化

我有个钙钛矿结构需要优化几何并计算带隙。

能带结构

计算石墨烯沿Γ-M-K-Γ路径的能带结构。

故障排除

我的ABACUS计算不收敛,SCF一直振荡,帮我看看。

使用指南

基本工作流

  1. 准备赝势文件到 pseudos/ 目录
  2. 在MCP客户端中描述你的计算需求
  3. 服务器会自动设置参数并运行计算
  4. 查看结果和建议

常用计算类型

硅能带结构计算

计算硅晶体的能带结构,晶格常数5.43 Å,沿Γ-X-L-Γ路径。

钙钛矿结构优化

优化BaTiO3几何结构并计算电子性质。

收敛问题诊断

我的MoS2计算不收敛,SCF在-150.5和-150.8 Ry间振荡,用的ecutwfc=80 Ry。

PyABACUS工作流

用PyABACUS分析原子轨道重叠,需要LCAO计算和重叠矩阵。

基本工作流

  1. 创建结构
# 使用create_structure工具创建原子结构
structure = create_structure(
    formula_or_data="Si2",
    input_format="formula",
    crystalstructure="diamond",
    a=5.43
)
  1. 验证输入
# 验证计算参数
validation = validate_input(
    input_params={
        "ecutwfc": 100,
        "scf_thr": 1e-6,
        "basis_type": "pw"
    },
    structure_dict=structure["data"]
)
  1. 运行计算
# 执行SCF计算
scf_result = run_scf(
    structure_dict=structure["data"],
    input_params={
        "ecutwfc": 100,
        "scf_thr": 1e-6
    },
    kpoints_definition={
        "mode": "Monkhorst-Pack",
        "size": [4, 4, 4]
    },
    pseudo_potential_map={"Si": "Si.UPF"}
)
  1. 分析结果
# 查看计算结果和建议
print(scf_result["data"]["interpretation"])
print(scf_result["data"]["recommendations"])

Questions

About Abacus MCP Server

How do I install Abacus MCP Server?

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is Abacus MCP Server safe to use with an AI agent?

Its trust score is 51 out of 100 (fair). It passes 4 of the 6 static security checks run so far; the failures are listed above. It has no ConduID identity yet, so agent calls to it are not receipted.

Is Abacus MCP Server still maintained?

The last commit was 9 months ago. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
