mcp-astrology

출생 정보를 받아 서양 점성술 네이탈 차트(행성별 별자리·하우스, ASC·MC 텍스트 + 차트 PNG)를 반환하는 MCP 서버. "내 네이탈 차트 그려줘"라고 하면 차트 휠 이미지를 돌려준다.

구조·네이밍·PNG·설치 규약은 STANDARD.md를 따른다. mcp-qr skeleton 복제본.


계산 / 렌더

  • 계산: celestine — Swiss Ephemeris / JPL Horizons 대조 검증된 천체력.

  • 렌더: @astrodraw/astrochart(SVG) → jsdom으로 헤드리스 구동 → sharp로 PNG 변환.

  • 결정론적: 같은 입력 → 같은 차트.

IANA 존을 주면 해당 출생 시각의 DST를 반영해 오프셋을 산출한다.

  1. 구조화 텍스트 — 행성별 별자리·도수·하우스(역행 R 표시), ASC·MC

  2. 네이탈 차트 PNG (1080×1080)

TDQS

A3.7/5.0
Behavior3/5

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

No annotations are provided, so the description must disclose behavioral traits. It states what the tool calculates and returns but omits details like ephemeris used, precision, or whether network access is required. It is adequate but not comprehensive.

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?

The description is a single, clear sentence that front-loads the core purpose. It is efficient but could benefit from slightly more structure, such as separating input and output details.

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

Completeness4/5

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

Given the absence of output schema and siblings, the description adequately covers inputs, computation, and outputs (text and PNG). It is complete enough for an agent to understand and use the tool correctly.

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 description coverage is 100%, meaning the schema already documents all parameters. The description adds no additional meaning beyond the schema descriptions, so the baseline score of 3 is appropriate.

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 calculates a Western astrology natal chart from birth information, specifying inputs and outputs. It uses a specific verb ('calculate') and resource ('natal chart'), and distinguishes the tool's purpose without needing sibling differentiation.

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

Usage Guidelines3/5

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

The description implies usage for natal chart calculation but does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives. No siblings are provided, so the need is reduced, but the dimension expects some guidance.

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

A3.7/5.0
Disambiguation5/5

Only one tool exists, so no ambiguity. The description clearly defines its purpose.

Naming Consistency5/5

With a single tool, naming is inherently consistent.

Tool Count3/5

One tool for an astrology server feels thin; users typically expect multiple tools for different astrology functions.

Completeness2/5

Only natal chart calculation is available; missing common astrology features like transits, synastry, or progressions.
