Connect Claude Code
Claude Code adds Hiasynth as a remote server and signs in with the same one-click flow as Claude. Best if you live in a terminal.
Add the server
Run this in the project where you want Hiasynth available:
claude mcp add --transport http hiasynth https://mcp.hiasynth.coSign in
Inside Claude Code, type /mcp, pick hiasynth and follow the sign-in link. The Hiasynth page opens in your browser: sign in, read the card, approve. It will note that the client runs on your own machine. That's exactly right.
The /mcp screen after signing in
Ask
Back in the terminal:
Describe who lives within three kilometres of Södermalm in Stockholm, and what the area is like by day.
Claude Code calls Hiasynth, and you get a demographic profile and a picture of the place, footfall and all, without leaving your shell.
Add --scope user to the command to have Hiasynth in every project. Answers need a subscription on your Hiasynth account; see Pricing.
Next, set it up for your job: a few lines of instructions turn your assistant into an expansion manager, an audience strategist or a location scout that works the same way every time. Stuck? Troubleshooting has the fix.
