Steps
1
Open Claude Desktop settings
Launch Claude Desktop. Click the ≡ menu (top-left) → Settings → Developer tab.
2
Edit the MCP configuration file
Click Edit Config. This opens claude_desktop_config.json in your default editor. If the file is empty, start with {}.
3
Add the SoftSignal server
Add the following inside the mcpServers object. Create the object if it doesn't exist yet.
{
"mcpServers": {
"softsignal": {
"type": "sse",
"url": "https://chat.getsoftsignal.com/sse"
}
}
}4
Save and restart Claude Desktop
Save the file and fully quit Claude Desktop, then reopen it.
5
Sign in when prompted
Claude Desktop will open a browser window asking for your subscriber email. Enter the email on your SoftSignal account. Check your inbox for a one-click sign-in link — no password needed.
6
Confirm the connection
Back in Claude Desktop, you should see SoftSignal listed under connected tools. Try asking: "What is managed money positioning in cotton right now?"
Troubleshooting
Sign-in link not arriving? Check your spam folder. The email comes from Firebase / [email protected].
Connection refused? Make sure you saved the config file and fully restarted Claude Desktop (quit from the menu bar, not just close the window).
Subscription not found? The email you enter must match your SoftSignal subscriber email exactly. Contact [email protected] if you're unsure which email is on file.
