LegalZoom
Business formation and legal servicesIndependent review. IonBin has no partnership with LegalZoom and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Online business formation, compliance filings and legal services. LegalZoom's connector lets supported AI assistants compare entity types, find attorney consultations and prepare documents, with sign-in required for account actions. Not legal advice.
IonBin provides general information and software comparisons, not tax, legal, accounting or financial advice. Tax and legal rules vary by situation and jurisdiction; consult a qualified professional (CPA, enrolled agent or attorney) before acting.
AI tools can make mistakes. Verify every figure against the original documents and official IRS or state guidance before filing or signing.
Redact Social Security numbers, account numbers and EINs before uploading documents to any AI assistant, and check its data-retention settings. Upload originals only to the filing or signing software.
Requirements vary by state. File through official sources such as the USPTO trademark search and your state’s Secretary of State site.

LLC packages

AI connector
Each AI client gets its own versioned set of tools, so a capability in one client may be missing in another. Authorization does not override plan, jurisdiction or service requirements. source ↗
How to use it with AI
How LegalZoom connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | Not documented LegalZoom has an official MCP server and Claude (incl. Claude Code) supports MCP, but LegalZoom's docs don't name this pairing. Auth setup may differ. LegalZoom MCP docs ↗Claude (incl. Claude Code) MCP docs ↗ | No documented route | Confirmed Claude Code with the Claude in Chrome extension (Chrome, Edge and other Chromium browsers) Claude (incl. Claude Code) browser docs ↗ | Confirmed Export from LegalZoom, then works on the files in your project; chat accepts attachments Claude (incl. Claude Code) docs ↗ |
| OpenAI Codex | Not documented LegalZoom has an official MCP server and OpenAI Codex supports MCP, but LegalZoom's docs don't name this pairing. Auth setup may differ. LegalZoom MCP docs ↗OpenAI Codex MCP docs ↗ | No documented route | Confirmed Only in the ChatGPT desktop app; not in the Codex CLI or IDE extension OpenAI Codex browser docs ↗ | Confirmed Export from LegalZoom, then works on local repositories OpenAI Codex docs ↗ |
| Google Antigravity | Not documented LegalZoom has an official MCP server and Google Antigravity supports MCP, but LegalZoom's docs don't name this pairing. Auth setup may differ. LegalZoom MCP docs ↗Google Antigravity MCP docs ↗ | No documented route | Confirmed Browser subagent via /browser, documented as an Antigravity App feature; the IDE has separate browser docs Google Antigravity browser docs ↗ | Confirmed Export from LegalZoom, then works on local projects and worktrees Google Antigravity docs ↗ |
Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
