CONNECT APP
Build with Mailosaur
Mailosaur removes the frustration of testing everything a user might do. Test password resets, replies, two-factor logins, and more.

Give your agent Mailosaur tools
Every Mailosaur action is exposed as an MCP tool on Pipedream's remote server. Point a client at it with your end user's ID and Connect resolves that user's Mailosaur account for each tool call — you store no tokens.
// accessToken: mint a short-lived token with the Connect SDK — see the MCP guide
const transport = new StreamableHTTPClientTransport(
new URL("https://remote.mcp.pipedream.net/v3"),
{
requestInit: {
headers: {
Authorization: `Bearer ${accessToken}`,
"x-pd-project-id": "{project_id}",
"x-pd-environment": "production",
"x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
"x-pd-app-slug": "mailosaur",
},
},
},
)
const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)
const { tools } = await mcp.listTools()
// e.g. run Create and Send Email via Mailosaur:
const result = await mcp.callTool({

Run Mailosaur actions from your backend
Connect a user's Mailosaur account once, then run Create and Send Email via Mailosaur on their behalf from your own code — TypeScript, Python, or plain HTTP.

const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
