Publish a listing without leaving your editor

Most sellers write a listing in an AI client and then re-type it into our publish wizard. You can now skip the second half.

sigrix-mcp is an open-source MCP server that turns a seller API token into tools your client can call:

claude mcp add sigrix -e SIGRIX_SELLER_TOKEN=sgx_... -- uvx sigrix-mcp

Create your token in Settings — it is shown once, and the card shows you the exact configuration for Claude Desktop, Cursor and VS Code too. Then ask your client for a draft: it creates it, asks Sigrix what submit would refuse, fixes what it can and submits when you say so.

Three things it deliberately does not do. It does not publish — a submission is pending_review and a moderator decides, exactly as from the wizard. It does not carry rules of its own — when it tells you a draft is not ready, those are our words, quoted, so it cannot drift from what the wizard's own checklist says. And it does not read anything but your own listings: the token opens the listing routes and nothing else on your account.

The source is Apache-2.0 at github.com/sigrix-io/sigrix-mcp — read it before you paste a token into it. It is one of the projects on our open source page.
