SIGMAI
Secure local bridge between AI assistants and QGIS, with cartographic quality control.
SIGMAI lets AI assistants operate QGIS through a local, auditable command interface instead of screen automation. It ships a standards-compliant MCP server (JSON-RPC 2.0 over stdio) so Claude, Cursor, Codex and any other MCP client can connect; a consent layer where the user chooses between read-only, ask-every-time and allow-for-this-session, with output-folder sandboxing, per-session limits and an audit trail; and a cartographic engine that composes page-aware map layouts, fits the extent to the map frame, rounds the scale to the cartographic series, sizes the scale bar, computes the coordinate grid interval, builds a legend covering every visible layer, and then audits the result against an explicit rulebook whose findings tell the assistant what is wrong and how to fix it. The bridge binds to 127.0.0.1 only and requires a bearer token. Normal operation never exposes arbitrary Python execution; Developer Mode is explicit, warning-protected and disabled by default. SIGMAI runs on the Python bundled with QGIS/OSGeo4W. Developed by Luan da Silva Cortes Maciel as a research product associated with Herpeto Mantiqueira.
