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",
},
})# access_token: mint a short-lived token with the Connect SDK — see the MCP guide

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.# The path segment is the target URL, URL-safe base64 encoded:
# https://api.taxjar.com/v2/categories
curl "https://api.pipedream.com/v1/connect/{project_id}/proxy/aHR0cHM6Ly9hcGkudGF4amFyLmNvbS92Mi9jYXRlZ29yaWVz?external_user_id={external_user_id}&account_id=apn_xxxxxxx" \

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.

projectId: process.env.PIPEDREAM_PROJECT_ID!,
