Connect Boundr and your agent gets 7 tools, among them find_boundaries_at_point, get_boundary_bbox, get_boundary_by_code. It answers at https://mcp.boundr.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
UK administrative boundary data from OS Boundary Line: name search, point lookup, GeoJSON geometries
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
find_boundaries_at_point | Find all UK administrative boundaries that geographically contain a coordinate point. Use this to answer "what county/borough/ward is this location in?" for a latitude/longitude. Returns lightweight metadata only — no geometry. If you need Inputs: lat, lng, boundary_types |
get_boundary_bbox | Get the bounding box and centroid for a boundary by its ONS census code. Returns min_lat, max_lat, min_lng, max_lng, centroid_lat, centroid_lng. Pass the bbox values directly to Knotsure's sightings_in_bbox() or geographic_summary(). Much c Inputs: code |
get_boundary_by_code | Look up metadata for a single UK boundary by its ONS census code. No geometry. Use this when you already have a census code (e.g. from search_boundaries_by_name() or find_boundaries_at_point()) and need structured metadata such as area size Inputs: code |
get_boundary_geojson_by_code | Fetch the full GeoJSON geometry for a UK boundary by its ONS census code. Returns a GeoJSON Feature object (WGS-84 / EPSG:4326) suitable for rendering on a map or performing geometric analysis. The geometry can be large — county and ceremon Inputs: code |
get_boundary_geojson_simplified | Fetch simplified GeoJSON for a boundary by its ONS census code. Safe to embed directly in generated HTML map files. At the default tolerance (0.0001°) a constituency polygon shrinks from ~4,000 vertices to ~200–400 with no visible differenc Inputs: code, tolerance |
list_boundary_type_codes | Returns every valid UK boundary type code mapped to its human-readable label. Call this before using any tool that accepts a `boundary_type` or `boundary_types` argument so you know which codes are legal. Passing an unlisted code to another |
search_boundaries_by_name | Search for UK administrative boundaries by name (case-insensitive partial match). Use this to discover boundaries when you have a place name but not a code. Returns lightweight metadata only — no geometry. If you need to display or analyse Inputs: name, boundary_type |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.boundr.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.danielinniss. Endpoint host: mcp.boundr.dev. ARD identifier: urn:air:io.github.danielinniss:mcp:boundr.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
