  • Build full Maya birth charts with Haab date, Long Count, Calendar Round, Lord of the Night, Year Bearer and Cruz Maya
  • Convert between Gregorian dates and Long Count, and score compatibility between two birth dates
  • Look up reference lists and profiles for the twenty Tzolkin day signs, twenty trecenas and nineteen Haab periods
  • Compute Aztec tonalpohualli day signs, daily energy and trecenas, and browse Aztec day sign and trecena references
When to use it
Useful when building or answering questions for Mayan zodiac apps, nawal readings, daily energy feeds, editorial calendars, matchmaking features or Mexica calendar reference pages that need consistent, pre-composed readings.
Requirements
A remote MCP endpoint at roxyapi.com over streamable HTTP. Requires a RoxyAPI key sent in the X-API-Key header, obtained from a RoxyAPI account.
Before you install
The API key is a secret sent in the X-API-Key header; keep it out of logs and shared configs. All tools are read-only lookups and calculations, but requests and the dates you submit go to the third-party RoxyAPI service. Access depends on a paid or account-based API key.

Installation

In SourceWeft

  1. Open Mesoamerican Astrology MCP Server by RoxyAPI in the dashboard and add it to a workspace.
  2. Connect X-API-Key credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.roxyapi%2Fmesoamerican-astrology/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

post_mesoamerican_astrology_mayan_chart

Generate a Mayan chart - Tzolkin, Haab and Long Count calculator API

post_mesoamerican_astrology_mayan_long_count_convert

Convert a Maya Long Count - Long Count calendar converter API

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.

Mayan energy of the day: the Tzolkin day sign, its coefficient and its trecena for today or for any date you name, with a composed reading. Content is fixed for a given date and rolls over at midnight UTC, so a daily feed can cache it safely and an editorial calendar can be filled weeks ahead. Built for daily energy widgets, nawal of the day feeds and chatbot answers about what today carries.

One call fills a monthly grid that would otherwise take a request per day, and the answer is fixed for any month that has already begun. Built for calendar widgets, editorial planners and any app that shows a month of Maya dates at once.

post_mesoamerican_astrology_mayan_compatibility

Mayan nawal compatibility - Tzolkin pair analysis API

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.
