Circulus Map - air route calculation with projected map

Use this skill when the task is about aviation route planning, map projections, airport lookup, ETOPS, or generating shareable SVG route maps through a local Circulus Map setup.

Quick start

• Before using tools, make sure the local app is running with npm run dev and the MCP worker is running with npm run mcp:dev.
• Expect the local MCP endpoint at http://127.0.0.1:8788/mcp.
• For simple requests, call map.solve_query with shorthand input like JFK-LHR or 800nm@DEN.
• For advanced requests, build a MapSpecV1 object and call map.solve_spec.
• Use map.search_locations before solving when the user is unsure about codes or city names.
• Use map.get_airport when you need a single airport record with coordinates and runway metadata.
• Use map.render_svg only after the route/spec is stable.

Tool selection

• map.search_locations: best first step for ambiguous airport/city input.
• map.solve_query: fastest path for route-only requests and simple range rings.
• map.solve_spec: use when the user cares about projection, ETOPS, labels, markers, or multiple paths.
• map.list_scenarios: use when the user asks for examples or wants a starting point.
• map.render_svg: use for final export-ready output, not exploration.

Resources

• Read circulus://mapspec/schema before authoring a non-trivial MapSpecV1.
• Read circulus://projection/guide for projection choices.
• Read circulus://scenario/catalog and circulus://api/examples when you need examples quickly.

• For quick query and spec-writing guidance, read references/mapspec.md.
• For sample payloads, inspect assets/examples when bundled with this skill package.

Guardrails

• Stay within the MCP tool surface; do not invent unsupported write operations.
• Do not ask the MCP server to proxy arbitrary URLs or tile providers.
• Prefer map.solve_query over map.solve_spec unless explicit control is needed.
• If the local MCP server is unreachable, help the user restore the local app and worker before retrying tool calls.
