After checkout succeeds, refresh the entitlement cached by your local installation to unlock Pro immediately. Choose any of these:

1. Press Open Synapse
2. OR Open the local Synapse Dashboard and press Refresh in the User tab.
3. OR Run in your terminal:

   npx @myelixlabs/synapse-mcp auth refresh

   Copy

Download the public launcher directly if you do not want to use npm or the shell installer. Choose the file for your OS, save it as synapse-mcp (or synapse-mcp.exe on Windows), and put it on your PATH.

Synapse MCP runs locally, but installation and authentication need access to these servers:

• synapse-mcp.dev — web sign-in, dashboard, and device approval.
• api.synapse-mcp.dev — device auth and licence renewal API.
• downloads.synapse-mcp.dev — launcher and runtime downloads.

For offline usage or usage behind a corporate firewall, contact us for details about allow-listing, mirrored downloads, and managed deployment options.
