What is the ElectricSQL MCP Server?
The ElectricSQL MCP Server routes AI agents like Claude, ChatGPT, and Cursor directly to ElectricSQL via 2 tools. Sync Postgres data to your AI agent in real-time using ElectricSQL's HTTP Sync API — fetch shapes, stream updates, and query subsets. Powered by Vinkius — your credentials stay on your side of the connection, every request is auditable. Connect in under 2 minutes.
Built-in capabilities (2)
Tools for your AI Agents to operate ElectricSQL
Ask your AI agent "Sync the 'public.items' table from the beginning using get_shape." and get the answer without opening a single dashboard. With 2 tools connected to real ElectricSQL data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by Vinkius — your credentials never touch the AI model, every request is auditable. Connect in under two minutes.
Why teams choose Vinkius
One subscription gives you the infrastructure to connect your AI agents to thousands of MCP servers — and deploy your own to the Vinkius Edge. Your credentials stay yours. Your data flows directly between your agent and the API. DLP blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade routing and governance, zero maintenance.

Get shape on ElectricSQL (Sync Engine)
Use offset=-1 for initial sync. Sync a shape of data out of Postgres via GET
Post shape on ElectricSQL (Sync Engine)
Sync a shape of data out of Postgres via POST (Subset Snapshots)
What the ElectricSQL (Sync Engine) MCP Server unlocks
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.
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.
How it works
1. Subscribe to this server
2. Provide your Electric Service URL (e.g., your local or cloud Electric endpoint)
3. Start querying your Postgres data directly from Claude, Cursor, or any MCP client
Who is this for?
- Developers — build AI-powered tools that need live access to application data without complex backend plumbing.
- Data Engineers — inspect and sync specific database 'shapes' for analysis or debugging via natural language.
- Product Teams — monitor real-time system state or user activity directly within the AI chat interface.
Frequently asked questions about the ElectricSQL (Sync Engine) MCP Server
How do I perform an initial sync of a database table?
Use the get_shape tool and set the offset parameter to -1. This triggers ElectricSQL to send the full initial snapshot of the specified table.
What should I do if my SQL WHERE clause is too long for a standard URL?
You should use the post_shape tool. It sends the filtering criteria in the request body, which prevents '414 Request-URI Too Long' errors when using complex logic.
Can the AI agent receive updates automatically when data changes in Postgres?
Yes! By setting the live parameter to true in get_shape, the agent can establish a long-polling connection to stream incremental changes as they happen.
