Vedic Astrology and Kundli MCP Server by RoxyAPI

Find KP sublord changes

post_vedic_astrology_kp_sublord_changes

Read-only

Track when planets cross KP sublord boundaries (1-249 divisions) for precise Krishnamurti Paddhati event timing. Returns exact timestamps when a planet transitions between sublords, essential for prashna kundali analysis and dasha predictions. Use this to find favorable windows when benefic sublords are active. Supports Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn tracking over any date range.

Input Schema

TableJSON Schema

Name	Required	Description	Default
`planet`	Yes	Planet to track (case-insensitive). Valid values: Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn
`compact`	No	Set true for the same data in a compact shape: arrays of same-shaped objects arrive columnar as {"__cols":[names],"__rows":[[values]]}. Lossless, typically 40 to 52 percent fewer tokens.
`endDate`	Yes	End date for sublord change search (YYYY-MM-DD format)
`ayanamsa`	No	Ayanamsa system for sidereal conversion. "kp-newcomb" uses the KP-Newcomb dynamic formula, the most common choice for KP astrology. "kp-old" uses the Krishnamurti original table from KP Reader-1 with constant precession rate. "lahiri" uses Lahiri/Chitrapaksha ayanamsa, matching most traditional Vedic software. "raman" uses the B.V. Raman ayanamsa from Hindu Predictive Astrology, a recognised traditional school that sits about 1.45 degrees below Lahiri. Defaults to "kp-newcomb".	kp-newcomb
`nodeType`	No	Lunar node convention. "mean" is the smoothed average node, which always moves retrograde; "true" is the osculating node, which tracks the real perturbed node, oscillates up to about 1.5 degrees either side of the mean on a 173-day cycle, and can briefly turn direct. Neither is more correct and they almost always fall in the same sign. Applies to the Rahu and Ketu positions. Mean is the traditional Vedic default and what printed panchangs use; the choice can move a KP sub-lord in narrow boundary cases, where a span can be as small as 0.5 degrees. Defaults to "mean".	mean
`timezone`	No	IANA name (e.g. "America/New_York", "Europe/London") OR decimal hours from UTC. IANA resolved to the DST-correct offset for startDate. Output times are converted to this timezone. Defaults to 0 (UTC).
`startDate`	Yes	Start date for sublord change search (YYYY-MM-DD format)

TDQS

A4.3/5.0

Behavior4/5

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

With annotations already providing readOnlyHint=true and destructiveHint=false, the description adds value by specifying the output (exact timestamps), the supported planets, and the sublord division range (1-249). It does not contradict annotations and adds useful behavioral context beyond the safety profile.

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?

The description is four sentences, front-loaded with the core action, and each sentence adds information: core functionality, output type, use cases, and supported planets. There is no redundancy or wasted words. It is appropriately sized for the tool's complexity.

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?

Given the tool has 7 parameters and no output schema, the description explains the purpose and use cases but does not detail the output structure (e.g., list of events with planet, timestamp, sublord). It vaguely says 'returns exact timestamps'. For a tool with many parameters and no output schema, the description should provide more specifics about the return format to be fully complete.

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

Parameters4/5

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

Schema coverage is 100% with parameter descriptions already present. The description adds conceptual meaning like 'KP sublord boundaries (1-249 divisions)' and explains the purpose of the tool, which helps an agent understand the parameters' role beyond the schema. It does not duplicate but enhances understanding.

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 tracks when planets cross KP sublord boundaries (1-249 divisions) and returns exact timestamps. It specifies the resource (sublord changes) and action (track/find), and distinguishes from siblings like post_vedic_astrology_kp_planets or post_vedic_astrology_kp_rasi_changes by mentioning 'sublord boundaries' and 'prashna kundali analysis and dasha predictions'.

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

Usage Guidelines4/5

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

The description gives a clear use case: 'Use this to find favorable windows when benefic sublords are active.' It implies the tool is for event timing over a date range but does not explicitly compare to siblings like post_vedic_astrology_kp_planets_interval. The context is clear but lacks explicit exclusions or alternatives.

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

A3.6/5.0

Disambiguation3/5

Many tools have overlapping concepts (multiple dasha levels, monthly variants, aspects, transit), but detailed descriptions clarify each one's distinct purpose. Still, a few pairs like planetary_positions vs birth_chart or aspects_monthly vs aspects_lunar could confuse an agent initially.

Naming Consistency5/5

All tools follow a strict get_vedic_astrology_* or post_vedic_astrology_* prefix with snake_case resource names. The pattern is predictable and uniformly applied, including the hierarchical dasha drill-downs, making it easy to infer tool families.

Tool Count1/5

With 50 tools, the server is extremely heavy. Many are monthly, interval, or sub-level variants that could be parameterized or consolidated, making the set feel bloated and difficult to navigate for an agent.

Completeness5/5

The tool set covers nearly the entire Vedic astrology domain: reference data (nakshatras, rashis, yoga glossary), core charts (birth, navamsa, divisional), dasha hierarchy, transits, compatibility, doshas, panchang, KP system, and advanced calculations like Shadbala and Ashtakavarga. No significant gaps are apparent.
