如何在 Cline 上设置
要将此服务器与 Cline 一起使用，您需要编辑 Claude 桌面应用程序的配置文件：
在以下路径中创建或编辑配置文件：
~/Library/Application Support/Claude/claude_desktop_config.json添加以下内容（或者将其添加到现有的 mcpServers 对象中，如果已经存在）：
{ "mcpServers": { "arithmetic": { "command": "node", "args": ["/Users/y_nakasaka/Documents/Cline/MCP/arithmetic-server/src/index.js"], "disabled": false, "autoApprove": [] } } }重启 Claude 桌面应用程序
使用示例
您可以使用以下提示调用 Cline 中的算术工具：
“将 5 加 3。”
“从 10 中减去 7。”
“将 6 乘以 8。”
“用 20 除以 4。”

TDQS
D1/5.0
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Tool has no description.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness1/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Tool has no description.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness1/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Tool has no description.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters1/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Tool has no description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose1/5
Does the description clearly state what the tool does and how it differs from similar tools?
Tool has no description.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines1/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Tool has no description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

C2.2/5.0
Scored across 4 tools
Disambiguation5/5
Each tool has a clearly distinct mathematical operation: addition, division, multiplication, and subtraction. There is no overlap in purpose, and an agent can easily distinguish between them based on their names alone.
Naming Consistency5/5
All tool names follow a consistent pattern of simple, lowercase verbs that directly describe the arithmetic operation. There are no deviations in style or convention across the set.
Tool Count5/5
With 4 tools covering the basic arithmetic operations, the count is well-scoped and appropriate for a server focused on simple calculations. Each tool earns its place without redundancy or gaps in this limited domain.
Completeness5/5
For a basic arithmetic server, the tool set is complete, covering all fundamental operations: addition, subtraction, multiplication, and division. There are no obvious gaps, and agents can perform essential calculations without dead ends.
