IMPLEMENTATION
Call this tool
Connect a user's AWS account once, then configure and run DynamoDB - Update Item from your backend or agent.
import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "aws-dynamodb-update-item",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
aws: { authProvisionId: "apn_xxxxxxx" },
region: "AWS Region",
tableName: "Table Name",
},
})
console.log(result)curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \

const transport = new StreamableHTTPClientTransport(

},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({
name: "aws-dynamodb-update-item",
arguments: {
region: "AWS Region",
tableName: "Table Name",
},
