Binance MCP Server

顺势指标

indicator_cci
Read-only

Calculates CCI from Binance futures K-lines to reveal overbought and oversold conditions. Returns a stable series normalized by typical price, enabling analysis for any symbol and interval.

Instructions

直连版:拉取 K 线后计算 CCI,返回稳定序列(以典型价离差归一,可正可负)。

Behavior3/5

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

annotations 已具备 readOnlyHint=true 和 openWorldHint=true,安全画像无需描述额外承担。描述补充了有价值的行为:该工具会自行拉取 K 线数据('直连版',暗示每次调用有网络数据成本),并说明输出序列经过典型价离差归一、可正可负,这对输出解读有帮助。但'直连版'与'稳定序列'均为未定义术语,行为信息整体有仍显单薄。

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

Conciseness4/5

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

全文一句,简短且关键信息(计算对象、计算方式、输出特性)靠前集中,无明显冗余。'直连版'和'稳定序列'两个术语富有信息量但仍需解释,既保持压缩的评价则不算5。

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?

存在 output schema 和 input 枚举/默认值,承担了返回结构与合法取值的一部分职责,因此描述不必解释返回值字段。但对一个需要 symbol/interval/period/limit 的调用,描述中的参数说明缺失如 period 对计算的影响、limit 对序列长度的行为,'直连版'的语义也未澄清,中等复杂二元完整度仅达基本线。

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

Parameters2/5

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

schema 的参数描述覆盖率为 0%,描述必须补偿,但描述几乎未涉及参数。'拉取K线'间接指向 symbol 与 interval,却完全没有说明 period 的含义(只能凭默认值20和CCI常识硬推),limit 更是完全未提及。对 0% 覆盖率的 schema 来说,这是明显的补偿缺口。

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

Purpose4/5

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

描述明确说明了动作(拉取K线后计算CCI)和结果(返回归一化、可正可负的稳定序列),并交代了计算口径(以典型价离差归一),不是对工具名的简单复述。但未与同组大量 indicator_* 兄弟工具做任何区分,依赖工具名自身传达'这是CCI指标',因此不足5分。

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?

描述只说明了工具做什么(拉K线算CCI),没有给出任何'何时用本工具而非替代品'的指引。面对 indicator_multi、indicator_macd_rsi、indicator_bb_rsi 等复合工具,以及十余个单指标工具,描述未说明何时应选 CCI、何时应选其他指标或复合工具。'直连版'一词似乎暗示存在非直连版本,但没有解释其适用取舍,属于不完整或无用的指引。

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