Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (post_mesoamerican_astrology_mayan_long_count_convert). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability76
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 6664 tokens (~370/item across 18 items; 18 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Tools include usage examples.Pass
Stability & Change Management53
- Stability observed for 16 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 18 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 18 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Mesoamerican Astrology MCP Server by RoxyAPI server?

{"date":"2012-12-21"} post_mesoamerican_astrology_mayan_chart Generate a Mayan chart - Tzolkin, Haab and Long Count calculator API ~702
Mayan astrology birth chart from one date: the Tzolkin day sign and coefficient, the Haab date, the full Long Count with its day count, the Calendar Round, the Lord of the Night, the Year Bearer of the Haab year and the five point Cruz Maya, each with composed readings. Built for nawal readings, birth chart features and multi domain spiritual apps that show a Mayan card beside a natal chart. Every school split in the domain is a typed parameter and comes back echoed, so the chart can be reproduced exactly.

{"date":"2012-12-21"} post_mesoamerican_astrology_mayan_compatibility Mayan nawal compatibility - Tzolkin pair analysis API ~555
Mayan compatibility between two birth dates, published as its parts rather than as a verdict: both nawals with their coefficients and trecenas, the five structural ties the pair either has or does not, the weight each tie carries, and a composite score built from them. Built for matchmaking features, relationship reports and compatibility widgets that need to show their working. The scoring weights are stated on every response so a caller can re-derive the number or replace it.

Maya Long Count converter that runs both ways: give it a Gregorian date and it returns the Long Count, give it a dotted Long Count and it returns the date. Every answer carries the Julian Day Number, the elapsed day count and the Calendar Round, and the correlation constant is a typed parameter so a value can be matched against any published inscription reading. Built for epigraphy tools, museum and education apps, and anything that has to place a Maya date on a civil calendar.
