77 Trust /100
Trust breakdown (7 categories)

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 Security89
Transport & Reachability100
Schema Quality & AI Usability69
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 27675 tokens (~232/item across 119 items; 105 tools + 14 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
  • Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage86
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 51% of tool parameters carry a description.Partial
  • Structured output schemas are declared (96% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 105 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 107 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
Install

How do I install the AstroWay Core astrology MCP server?

AstroWay Core astrology is a hosted endpoint at https://mcp.astroway.info/mcp/core, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 105 exposed · ~26,779 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
astroway_account_status ~73

Check current API key status: tier, credit balance, rate limits, monthly cycle reset. Run this BEFORE invoking expensive endpoints (Tier 4+ at 100+ credits, Tier 6/7 at 500-5000 credits) to confirm the user has budget. Returns plain-text human-readable summary.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

astroway_agent_tools ~405

Tool definitions for an agent framework, generated from the live OpenAPI document, so the schema a model fills is the schema the endpoint validates. `format=openai` (default) returns `{ type, function }` objects you can spread straight into a chat completion; `format=anthropic` returns `{ name, description, input_schema }`. The objects carry nothing of ours: how to call each tool lives in a separate `executors` map keyed by tool name, because an unexpected key inside a vendor tool object is a 400 at their end. [Group: Agent Platform] [Endpoint: GET /v1/agent/tools] [Cost: see your plan — endpoint not in the public credit manifest]

NameTypeReqDescription
fieldsstring–Compact mode: comma-separated dotted paths to keep, relative to `data`, e.g. "planets.name,planets.longitude,houses.cusp". Omit for the whole response.
formatstring–Which vendor contract the tool objects follow. `openai` returns `{ type, function }`, `anthropic` returns `{ name, description, input_schema }`.
limitinteger–How many tools to return. The ceiling is the OpenAI limit of 128 functions per request; models degrade well before it. Anything left out is counted in `totalMatched`.
precisioninteger–Compact mode: round fractional numbers to this many decimals. Longitudes carry 14 by default; 2 is finer than any chart is drawn.
qstring–Free-text filter applied within the selection, matched against path, summary, description and group.
selectstring–What to hand over: `starter` (the curated set, the default), `all`, `group:<tag>` such as `group:Vedic`, or `paths:/chart,/synastry` for an explicit list. An unknown path is named in `notes` rather t…

astroway_geo_acg_best_places ~289

Rank cities against the astrocartography lines of a chart for one of the 19 life categories. Distance to a line is computed from the body hour angle and altitude rather than against a discretised polyline, so it is exact: the distance to a horizon line IS the altitude in degrees of arc, and a meridian line offset is the hour angle times cos(latitude). Supportive and challenging totals are returned separately with every contributing line and its distance, so a strong-but-turbulent city is distinguishable from an average one. Bundled GeoNames set of 34,028 places above 15,000 people. [Group: Astro-Geography] [Endpoint: POST /v1/acg/best-places] [Cost: 50 credits (Tier 3)]

Common questions

What is the AstroWay Core astrology MCP server?

AstroWay Core astrology is an MCP server listed in the public MCP registry as info.astroway/core. Natal charts, planets, houses, aspects, dignities, rendering and the calendar. This page covers its hosted endpoint (https://mcp.astroway.info/mcp/core).

Is the AstroWay Core astrology MCP server safe to use?

AstroWay Core astrology scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the AstroWay Core astrology MCP server expose?

AstroWay Core astrology exposes 105 tools: astroway_account_status, astroway_cost_estimate, astroway_geo_acg, astroway_geo_acg_best_places, astroway_geo_acg_by_category, and 100 more. Their descriptions and schemas cost roughly 26,779 tokens of context every time the server is loaded.

Does the AstroWay Core astrology MCP server require authentication?

Yes. AstroWay Core astrology asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the AstroWay Core astrology MCP server still maintained?
