About ElectricSQL (Sync Engine) MCP Server
Connect your ElectricSQL sync engine to any AI agent to stream data directly from Postgres into your conversation context. This server leverages the Electric HTTP Sync API to fetch 'shapes' of data efficiently.
Cursor's Agent mode turns ElectricSQL (Sync Engine) into an in-editor superpower. Ask Cursor to generate code using live data from ElectricSQL (Sync Engine) and it fetches, processes, and writes. all in a single agentic loop. 2 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
What you can do
- Real-time Sync — Fetch data from Postgres tables with support for initial snapshots and incremental updates using log offsets.
- Shape Management — Define specific subsets of data (shapes) using SQL-like WHERE clauses and precise column selection.
- Live Streaming — Enable long-polling or Server-Sent Events (SSE) to keep your agent updated as data changes in the database.
- Complex Filtering — Use POST-based subset snapshots to handle complex WHERE clauses without hitting URL length limits.
- Pagination & Limits — Efficiently browse large datasets with built-in limit, offset_rows, and order_by support.
The ElectricSQL (Sync Engine) MCP Server exposes 2 tools through the Vinkius. Connect it to Cursor in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
