Comprehensive Model Context Protocol server for managing Home Assistant through AI assistants.
Nothing to run from here
Cosine Astro is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Astrology: natal charts, transits, synastry, retrogrades, profections. Computed offline.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user cosine-astro-mcp '--' npx -y cosine-astro-mcp
# 2 — ask your agent for something these tools do
# natal_chart, transits, synastry and 3 more
Cosine Astro costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Cosine Astro as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user cosine-astro-mcp '--' npx -y cosine-astro-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
6 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Cast a tropical natal (birth) chart: the ten planets with sign, degree, house and retrograde flag; Ascendant and Midheaven; twelve house cusps (Placidus by default); major aspects with orbs and applying/separating; and the dominant element and modality. Works without a birth time (no angles or…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| date | string | yes | Birth date (local calendar date), YYYY-MM-DD |
| time | string | no | — |
| timezone | string | no | — |
| latitude | number | no | Birthplace latitude in degrees, north positive |
| longitude | number | no | Birthplace longitude in degrees, east positive (New York is about -74.0) |
| city | string | no | — |
| house_system | string | no | House system. Placidus (default) falls back to whole-sign inside the polar circles, where it has no solution. |
Planet positions for a date and time (default: now), and, given a natal chart, the major aspects the transiting planets make to the natal planets, Ascendant and Midheaven within an orb (default 2°), with the natal house each transiting planet is passing through.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| date | string | no | Date of the transits, YYYY-MM-DD. Omit for the current moment. |
| time | string | no | Local time of the transits, HH:MM (default 12:00 when a date is given) |
| timezone | string | no | IANA time zone for the transit date and output times (default: the natal chart's zone, else UTC) |
| natal | object | no | The natal chart to compare against. Omit to get only the planets' positions. |
| max_orb | number | no | Largest orb in degrees for transit-to-natal aspects (default 2) |
Compare two natal charts: the major aspects between person A's planets (and Ascendant) and person B's, with orbs (conjunction/opposition 6°, square/trine 5°, sextile 3°), where each person's planets fall in the other's houses, and a simple descriptive tally (not a compatibility score).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| person_a | object | yes | First person's birth data |
| person_b | object | yes | Second person's birth data |
Mercury retrograde periods overlapping a date range (default: the next 12 months): pre-shadow start, station retrograde, station direct and post-shadow end (to about a minute, in UTC and a chosen time zone), with the degrees and signs of the two stations.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| start_date | string | no | Start of the range, YYYY-MM-DD (default: today) |
| end_date | string | no | End of the range, inclusive, YYYY-MM-DD (default: one year after the start). At most 30 years. |
| timezone | string | no | IANA time zone for the range and the local times in the output (default UTC) |
Hellenistic annual profection for an age or a date: the profected house (whole-sign, counted from the Ascendant; from the Sun's sign if the birth time is unknown), its sign, the lord of the year (traditional ruler, with the modern co-ruler) and where that lord sits in the natal chart, plus the…
| Parameter | Type | Required | Notes |
|---|---|---|---|
| age | integer | no | Age in completed years. Takes precedence over on_date. |
| on_date | string | no | Date to find the profection year for, YYYY-MM-DD (default: today in the birth time zone) |
The Moon's phase at a moment (default: now): phase name, illuminated fraction, Sun–Moon angle, days since new moon, the Moon's and Sun's signs, and the next new, first-quarter, full and last-quarter moons.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| date | string | no | Date, YYYY-MM-DD. Omit for the current moment. |
| time | string | no | Local time, HH:MM (default 12:00 when a date is given) |

Release 0.1.0 · scanned 18 Oct 2026
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Implementation sourceread
Package metadataread
Live transportnot available
Tools were statically extracted from the published source (6 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.1.0. Pin a release below and the command asks for exactly that one.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Cosine Astro can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
