Frequently Asked Questions
How do I connect TaxJar to my app?
Use Weavz Hosted Connect for Custom authentication. Install the SDK, create a connection through the connect portal or API, then execute tools programmatically.
What tools does TaxJar support?
TaxJar supports 7 tools including Calculate Tax, Get Rates For Location, Validate Address, List Tax Categories, Create Order Transaction, and more.
Can I use TaxJar with AI agents?
Yes. Add TaxJar to an MCP server in Tool Mode or Code Mode. Code Mode provides 3 meta-tools with on-demand API discovery so agents can compose stateful workflows without loading every action schema up front.
How do I connect TaxJar to ChatGPT or Claude?
Open the Weavz connector setup, sign in, choose a workspace, and add TaxJar as an approved app. ChatGPT, Claude, and other remote MCP clients can then call the scoped TaxJar tools exposed by that workspace.
Does TaxJar work with Claude Code, Cursor, Codex, and local agents?

What can I ask an AI agent to do with TaxJar?
TaxJar exposes 7 tools, including Calculate Tax, Get Rates For Location, Validate Address, List Tax Categories, Create Order Transaction, and more. Use Weavz to keep credentials scoped, require approval for sensitive work, and audit what the agent did.
Can TaxJar be used in stateful agent workflows?
Yes. Agents can combine TaxJar tools with Filesystem, State KV, Human Gates, input partials, and other workspace integrations while keeping execution scoped to the selected workspace or end user.
