Sync Postgres Subsets with the MCP Server

Cline runs the `get_shape` tool to pull live Postgres data directly into your VS Code environment. Setting the offset to -1 forces an initial sync, giving the agent absolute certainty about the current database state before it writes a single line of code. You stop manually exporting SQL dumps for context. The agent connects to the HTTP Sync API, reads the exact table structures, and immediately starts building your application logic based on reality.

Create Active Shape Snapshots

Firing the `post_shape` tool allows Cline to define strict data boundaries for whatever feature it is building. If you ask for a live chat component, the agent requests a subset snapshot of just the messages table. This targeted approach prevents context bloat. By isolating only the necessary Postgres records, the agent writes the React hooks, tests the integration, and shows you the working diff without getting distracted by unrelated schema details.

End-to-End Reactive Development

Because `get_shape` and `post_shape` operate directly inside your editor, Cline acts as a full-stack developer. It fetches the sync shape, creates the necessary frontend files, and stages the commit in one continuous motion. You get actual working features instead of just boilerplate. The MCP connection ensures the agent understands the real-time data flow, resulting in accurate API implementations that work on the first try.

Common questions about ElectricSQL (Sync Engine) MCP in Cline

Click the MCP Servers icon in the Cline sidebar. You can add the Streamable HTTP transport URL under the Remote Servers tab, or edit your `cline_mcp_settings.json` file manually.

The agent instantly pulls the required Postgres shapes to understand your data model. It then writes the code, builds the components, and verifies the logic against the live database state.

Yes. Access to real subset snapshots means the agent generates integration tests based on actual database shapes, rather than guessing your schema structure.

It requests specific boundaries using the POST method. This keeps the payload small and ensures VS Code does not crash from massive data dumps.

Your database records never leave your local machine. The server processes the HTTP Sync API traffic entirely within your environment, ensuring your subset snapshots remain isolated from the broader internet.
