astroway_agent_toolsTool definitions for an agent framework, generated from the live OpenAPI document, so the schema a model fills is the schema the endpoint validates.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
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.

Description, as the server wrote it
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.

Latitudes where a fixed star and a planet are angular at the same moment, which is how Brady tabulates a paran: not a place, a latitude. Twelve event pairs per star and planet (rise, set, culminate, anticulminate, minus meridian against meridian, which is a shared right ascension rather than a paran). Each row carries the houses of the technique in plain form: which body does what, the latitude, and the meridian where it happens at this chart moment. Solved on hour angles rather than by intersecting map polylines, so the latitude is exact rather than quantised to the polyline step.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as core. Review it before you use it.

Anlyon alternative

83 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
