3. Claude Desktop bridge (optional)

If remote connectors are not on your plan, use the local bridge file in GitHub: mcp/stacksignal-bridge.mjs. It speaks MCP over stdio and forwards to the live /mcp endpoint, so all 7 tools stay in sync (scan_website, analyze_gaps, find_connect, bulk_scan, draft_pitch, list_signals, list_capabilities).
