Automated data sync for Mastra AI

Integrate `get_shape` into your agent's toolset to pull fresh Postgres snapshots. It handles the initial sync with an offset of -1. Your workflows now base decisions on current database state. No more stale context during critical branching logic.

Conditional data subsets for Mastra AI

Use `post_shape` to request specific data subsets based on workflow triggers. It allows your agents to fetch precise records mid-execution. This keeps your agent's context window focused. It saves tokens and speeds up the decision process.

Reliable MCP Server tool execution

Mastra handles the tool calling through its native engine. You get built-in retry logic and error handling for every sync request. If a sync fails, the workflow catches it. You can define backup paths to ensure the agent stays functional.

Setup guide

Set up ElectricSQL (Sync Engine) MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All ElectricSQL (Sync Engine) tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "electricsql-sync-engine-mcp-client",
  servers: {
    "electricsql-sync-engine-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "ElectricSQL (Sync Engine) Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to ElectricSQL (Sync Engine) tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent ElectricSQL (Sync Engine) transactions"
);
console.log(result.text);

Common questions about ElectricSQL (Sync Engine) MCP in Mastra AI

Register the MCP client in your server configuration. The agent automatically detects `get_shape` and `post_shape` for use in your step definitions.

Yes, the tools are compatible with the built-in retry engine. If the sync request fails, the workflow can attempt a fetch again using exponential backoff.

You can wrap tool calls in approval requirements. This forces the agent to pause until you verify the shape request manually.

It excels at it. Each step can pull a different shape, allowing the agent to gather data progressively throughout the workflow.

The server acts as a gatekeeper. It only transmits the specific data subsets requested by the agent and does not expose the underlying schema structure.
