Bring your own agent

Every Dezfil runs an MCP server. Connect Claude Code, Codex, Cursor or another MCP client, and your agent reads and builds your maps, data and workflows, with your account's rights.

Claude Code
$ claude mcp add --transport http dezfil 'http://localhost:3000/api/mcp' --header 'Authorization: Bearer ${DEZFIL_API_TOKEN}'

Connect your database

Dezfil reads a table as a snapshot you can refresh later, filters it on the database, and puts every row in its place. Nothing is written back.

Publish maps in seconds

Publish gives a map a link anyone can open, with no account. Embed gives the code for a web page. Your later edits reach readers on their next load.

trees.csv82,064 rows
Import

CSV, GeoJSON, Shapefiles, a link, Overture Maps, OpenStreetMap or a PostGIS database.

SELECT zone, sum(pickups) …pickups
Query and style

SQL with DuckDB's spatial functions. Points, arcs, hex bins, 3D buildings, flows and time. Basemap, widgets and an editable legend.

Run all2 steps
Keep it running

Workflows chain tools such as Filter rows and Spatial join. Run all repeats the chain when the data changes.

Start your instance

Two commands on any machine with Docker. Your maps and data stay on your machine, in one volume.

  1. 1
    Pull the image
    $docker pull ghcr.io/dezfil/dezfil
