Juhe Exchange Rates MCP Server

一个提供实时全球货币汇率查询功能的模型上下文协议（Model Context Protocol）服务器。该服务器使大型语言模型（LLMs）能够获取实时货币汇率情况。

Components

Tools

服务器实现了一个工具:

  • query_exchange_rates: 根据货币的三位字母代码查询两者之间的兑换汇率

    • 需要传入 "from_code"（货币的三位字母货币代码）作为必须的字符串参数。

    • 需要传入 "to_code"（货币的三位字母货币代码）作为必须的字符串参数。

async def query_exchange_rates(
    from_code: str = Field(description="您希望转换的货币的三位字母货币代码。如：CNY"),
    to_code : str = Field(description="您希望转换为目标货币的三位字母货币代码。如：USD")
) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]:

Install

This server requires Python 3.10 or higher. Install dependencies using uv (recommended) or pip

Using uv (recommended)

When using uv no specific installation is needed. We will use uvx to directly run jexchange-mcp-server.

uvx jexchange-mcp-server

Using PIP

Alternatively you can install jexchange-mcp-server via pip:

pip install jexchange-mcp-server

After installation, you can run it as a script using:

python -m jexchange_mcp_server

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description bears full burden. It only says 'query' implying read-only but does not disclose whether it is real-time, requires internet, or error handling.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, no wasted words, directly to the point.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool is simple with 2 params, no output schema. Description covers purpose and parameters, but lacks details on return format or constraints.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% so baseline is 3. The description adds no new meaning beyond what the schema already provides for the parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool queries exchange rates between two currencies using three-letter codes, which is a specific verb+resource and distinguishes from any potential siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use or not use this tool, no prerequisites or alternatives mentioned despite being a simple query tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3.4/5.0
Disambiguation5/5

With only one tool, there is no possibility of confusion or overlap between tools. The single tool's purpose is clearly defined.

Naming Consistency5/5

The tool name 'query_exchange_rates' follows a clear verb_noun pattern. Although there is only one tool, the convention is consistent and descriptive.

Tool Count3/5

A single tool is borderline for an exchange rates server. While basic queries are covered, the lack of additional tools for listing currencies or performing conversions makes the set feel minimal for the domain.

Completeness2/5

The tool only supports querying an exchange rate between two currencies. Notably missing are operations to list supported currencies, fetch all rates, or convert amounts, which are standard for exchange rate services.
