Why people use ElectricSQL (Sync Engine)
ElectricSQL (Sync Engine) for Real-time Postgres Data Streaming
This Connector fixes that by creating a live bridge. Your agent stays connected to your Postgres tables. When you ask a question, it already knows the current state because it has been streaming those updates in the background. You get the right answer the first time.
What Vinkius changes
You get a live, filtered feed of your Postgres data directly into your agent's context.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about ElectricSQL.
The practical details behind the request, access and result.
How can I connect my Postgres database to Claude?
You can connect your Postgres database by using this Connector to bridge the data. It allows your agent to see your database tables as a live feed of information.
Can I see live updates from my database in my AI agent?
Yes, this Connector supports live updates. It keeps your agent informed of changes in your Postgres database in real-time so you always have the latest data.
Does ElectricSQL (Sync Engine) support complex SQL filters?
Yes, it handles complex filtering. You can use the sync engine to pull specific subsets of data based on multiple conditions without hitting URL limits.
How do I sync specific rows from Postgres to my AI client?
You define specific data shapes, which are just subsets of your tables. The Connector then pulls only those rows into your agent's context for you.
Can I use ElectricSQL (Sync Engine) for real-time monitoring?
That is one of its primary uses. It allows your agent to watch for changes in your database and notify you immediately when something happens.
What is a data shape in ElectricSQL?
A data shape is a specific subset of your database table. It lets you choose exactly which rows and columns the agent should see, keeping the context clean and relevant.
How do I perform an initial sync of a database table?
Use the get_shape capability 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 capability. 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.
