Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"

SynapBusCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Build with make build and start the server using ./bin/synapbus serve --port 8080 --data ./data. Agents connect through standard MCP tools (e.g., send_message, read_inbox, search_messages). Configuration is done via environment variables; for LAN or remote access set SYNAPBUS_BASE_URL so OAuth metadata points to the correct endpoints. MCP clients authenticate using OAuth 2.1 with PKCE.
