MCP

Give your agent TaxJar tools

Every TaxJar 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 TaxJar 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": "taxjar",
      },
    },
  },
)

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// e.g. run Calculate Sales Tax:
const result = await mcp.callTool({
  name: "taxjar-calculate-sales-tax",
  arguments: {
    exemptionType: "Exemption Type",
    fromCountry: "From Country",
  },
})

API PROXY

Call the TaxJar API directly

For an endpoint with no pre-built tool, the Connect proxy forwards your request to the TaxJar API with the connected user's credentials attached. You store no tokens and write no refresh logic.

const resp = await pd.proxy.get({
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  accountId: "apn_xxxxxxx",
  url: "https://api.taxjar.com/v2/categories",
})

// Any allowed TaxJar endpoint works here. Pipedream attaches the
// connected account's credentials to the outgoing request.

SDK

Run TaxJar actions from your backend

Connect a user's TaxJar account once, then run Calculate Sales Tax on their behalf from your own code — TypeScript, Python, or plain HTTP.

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: "taxjar-calculate-sales-tax",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    taxjar: { authProvisionId: "apn_xxxxxxx" },
    exemptionType: "Exemption Type",
    fromCountry: "From Country",
  },
})

EVENTS

TaxJar triggers

Event sources your backend can deploy for users and receive through a webhook.

No TaxJar triggers are available yet.

MULTI-APP

Use TaxJar with other popular apps

Most products don't stop at one integration. Pair TaxJar with the other apps your users rely on, and ship use cases that span both.
