Data offered docs-verified: PostGIS database connection via MCP
Formats llm-inferred: MCP stdio
Access docs-verified: Open source under the ISC licence; requires your own PostgreSQL database with the PostGIS extension and connection credentials (DB_URL_n, or legacy DB_HOST/DB_NAME/DB_USER/DB_PASSWORD).

Use cases llm-inferred: Let an AI assistant query consultancy PostGIS tables (site boundaries, drainage assets, constraint layers) through natural-language prompts · Map consultancy-specific table names via domain-aliases.json so natural-language table selection picks the right layer · Connect several project databases at once (DB_URL_1, DB_URL_2, DB_URL_3) to compare datasets across sites
Audience llm-inferred: GIS analysts · drainage engineers · hydrologists · civils engineers

Constraints llm-inferred: Provides a connection only; no datasets are bundled, so data must already exist in your PostGIS database · Requires Node.js v14 or higher and a PostgreSQL instance with PostGIS · Credentials are supplied via .env or MCP env variables; the legacy single-database DB_PASSWORD form is only a fallback · Tool names and the set of spatial operations exposed are not documented, and the metadata lists no tools · No UK-specific data or coverage is described · The docs do not state whether queries are read-only · No version, release or maintenance information is given beyond the listed dependency versions
