Avalara AvaTax MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Avalara AvaTax and the rest of your systems. It gives your agent 487 Avalara AvaTax actions (267 reads, 152 writes and 68 that wait for a confirmation) and holds the Avalara AvaTax credential itself, so the agent never does. It paces Avalara AvaTax's limits and records every call.

Questions

The Avalara AvaTax MCP server, answered.

Is there an Avalara AvaTax MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 487 Avalara AvaTax actions across definitions, items, companies and transactions, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Avalara AvaTax.

What do I need to connect Avalara AvaTax?

AvaTax account ID (the 10-digit number in the AvaTax portal under Settings > License and API keys), or an AvaTax… and AvaTax license key (Settings > License and API keys > Generate license key), or the password when account_id is a…. Plus your host. The free call account { op: "connections.requirements", service: "avalara_avatax" } lists exactly what to paste.

Can an AI agent delete or change things in Avalara AvaTax?

Only if its key allows it, and only with an explicit confirmation. 68 Avalara AvaTax actions are destructive, including delete a single item, delete a customer record and delete a single user. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Avalara AvaTax API limit?

actionlake paces every call to the limits in the Avalara AvaTax service file: 100 calls a second per connection. Repeated reads are answered from cache (264 Avalara AvaTax actions can be), which never reaches Avalara AvaTax.

What does an Avalara AvaTax action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (487 Avalara AvaTax actions page). Cache hits, searches, dry runs and calls Avalara AvaTax refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Avalara AvaTax API does it cover?

The Avalara AvaTax (sales tax, VAT and GST calculation, transactions, exemption certificates, filings) API AvaTax REST v2 v2 (Swagger 2.0, 497 operations) at rest.avatax.com by default, or the base URL set when you connect. It is built from Avalara AvaTax's documentation as read on 22 October 2026. 487 actions in 52 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Avalara AvaTax data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Avalara AvaTax credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
