What we're building,
shipped, and shipping.

MCP server listings are open to every seller

Any seller on Sigrix can now list an MCP server. Upload your own as a Python package: we review every version and deliver it only to the people who bought it, free or at a one-time price from $5 to $49. A server already on npm or PyPI can be listed free, and its buyers get a ready configuration for their AI client.

• New MCP server listings — Open to every seller: a server on npm or PyPI, free, or your own Python package
• New Packages delivered by Sigrix — Upload a pure-Python wheel; every version is reviewed and reaches buyers only
• New One-block install — Buyers paste one block into Claude Code, Claude Desktop or Cursor

Open-source commitments and custom solution onboarding

The parts of Sigrix that other people build on are open source: eight projects under Apache-2.0 in one GitHub organisation, from the Postern protocol to the runner inside every bundle, published under three commitments. And if you have built an MCP server, agent or integration that no listing type fits, the Sigrix team will onboard it with you: tell us what you made, and a person follows up and sets up the listing.

Sigrix-delivered MCP servers and a rebuilt marketplace

Founding sellers can now sell their own MCP server through Sigrix: they upload the package, a moderator reads the code, and buyers add it to Claude Code, Claude Desktop or Cursor from the listing's page. The marketplace is rebuilt, a new page explains how buying works, and a listing you bought keeps its page open to you if its seller withdraws it. We also fixed checkout and payout setup, and improved accessibility and access checks across the site.

• New MCP servers Sigrix delivers — Founding sellers upload their own MCP server. A moderator reads the code before it goes live, and the listing's page shows buyers how to add it to Claude Code, Claude Desktop or Cursor.
• New How buying works — A new page walks through finding a listing, checking it before you pay, and what you own afterwards.
• New n8n workflows — Their own section under Products. Each lists the services it calls, the credentials you provide and what it costs to run, and comes with none of the seller's credentials.
• New Seller badges, explained — A new Badges page says what each badge means. Trusted is now earned automatically, by the rule stated there, instead of being granted by hand.
• New Save for later — Prompt, persona, skill and crew pages gained a Save heart, so you can keep a listing in Favorites.
• New Custom solutions — Built an MCP server, agent or integration that doesn't fit a listing type? A new page explains how to bring it to Sigrix.
• New Four more open-source projects — Bailey, Gatehouse, sigrix-launcher and sigrix-runtime join Postern, sigrix-mcp and mullion on the open-source page.
• Imp A rebuilt marketplace — Cleaner cards with a quick-add button. Newest sorts by the date a listing was created, and Popular by likes, ratings and sales.
• Imp Daily AI allowance on screen — Wherever you run a model on Sigrix's AI key while building a listing, the page shows how many of today's tokens you have left.
• Imp Review covers more edits — A live product's setup steps, disclosed services or shipped files, or a crew's inputs, now send it back to review when they change.
• Imp Accessibility and phones — We fixed text and controls that fell below AA contrast in either theme, kept keyboard focus inside dialogs, and made pages, long names and emails fit a phone.
• Imp Tighter access checks — A listing that isn't public, and what a buyer pays for, now reach only the people meant to see them, on pages and APIs alike.
• Fix Payout accounts open in your country — Stripe payout accounts were all opened in Poland, the platform's country, and Stripe can't change that later. Setup now asks for your country first.
• Fix The page after paying — Coming back from Stripe showed an error even though the purchase had gone through. It now shows your receipt.
• Fix Signing in at checkout — The Sign in link works for guests, a new account returns to checkout, and an item you just bought isn't offered back in your cart.
• Fix Withdrawn listings — If a seller withdraws a listing you bought, its page now stays open to you, as your download already did.
• Fix Editing a returned listing — Editing a rejected or returned listing no longer locks it partway through. It goes back to review when you submit.
• Fix Sort by on your listings — Recent, Top selling and Most viewed on your listings page now sort as they say.

Your skills now install straight into Claude Code

One command connects Claude Code to your Sigrix library. Every skill you own appears as an installable plugin, and seller updates arrive with `/plugin marketplace update` — no re-downloading files.

• New Claude Code plugin feed — Your library as a private plugin marketplace — one command, every owned skill installable
• New sigrix-free marketplace — Every free skill, installable with zero account — sellers credited and linked
• New Feed URL management — Create, regenerate, revoke in Settings; shown once, hashed at rest, dies instantly on revoke
• Imp Post-purchase & library install commands — Exact per-skill `/plugin install` commands on the skill page, library, and checkout confirmation

No Cookie Banner, a Rebuilt Account, and Selling From Your AI Assistant

Sigrix has removed Google Analytics, so there is no cookie banner to answer; visits are now counted anonymously on Sigrix's own side and deleted after 90 days. Your account gains an activity page, a favourites page, a plugins page and a purchases shelf you can search and sort, and a signed-in cart now follows you between sessions. Buying on a phone puts the buy button above the fold. Sellers see views and sales per listing, are told when a listing is picked or promoted, and can manage listings from an AI assistant through the Sigrix listings MCP server.

Open source page now lists all three projects

The open-source page now covers everything Sigrix publishes: the Postern protocol, the sigrix-mcp publishing server, and mullion, the image pipeline behind every upload on the platform. Each project names the PyPI package you install, and mullion's licence, Python version and release are read from the copy this site actually runs rather than typed by hand.

• New mullion on the open-source page — The image pipeline extracted out of Sigrix — open, fit, watermark, encode — with its repository, licence and module list.
• New Published packages section — The three distributions Sigrix publishes, each linking to its own PyPI page, so nobody has to guess a package name.
• Imp Live package facts — mullion's licence, Python requirement and version are read from the installed distribution rather than written into the page.
• Imp Resources menu names every project — The menu read "Postern protocol" while the page already carried more than Postern.
• Imp sigrix-mcp release pinned by commit — The step holding the package's PyPI upload rights tracked a moving branch; it now names a commit, with a test that fails if that changes.

Refunds You Can Request, Your Data on Demand, and the First Listings Running on Sigrix

Buyers can now request a refund on a marketplace order and are told what was decided. Everyone can download a copy of their own data, switch off every email that is not essential, and keep two accounts in one browser. MCP servers reach the rest of the marketplace, appearing on seller storefronts, in listing counts and in search. Listings carry a purchase count, a test verdict measured by the platform rather than claimed by the seller, and a plain statement of what a skill's declared tools can do. Sellers get told when something sells, a rename that moves the address everywhere, and a re-save that no longer takes an approved listing down. And in the lab, the first pipeline listings run on Sigrix itself for the founding cohort, with the seller composing the page the buyer runs from.

• New Request a refund on an order — Buyers open the order and ask for a refund, and the request goes to a queue rather than an inbox.
• New Refund decisions, both ways — Staff are told a request arrived, and the buyer is told what was decided.

Image Prompts Get a Page of Their Own, and a Review Now Needs a Purchase

Image generation prompts get a rebuilt page that hands the buyer a finished prompt, shows every sample render, and lets sellers watermark them, with Prompts now split into Text generation and Image generation shelves. A review can only be left by someone who bought the listing, any listing can be reported from its page, and MCP servers carry an automated connection test verdict buyers can see before they commit. Every listing type publishes through the same guided flow, with a preview step, tag suggestions drawn from the category vocabulary, and payout setup asked where the price is set. Plus a new Sigrix mark, one top bar and one wayfinder on every page, and Postern, an open specification for licensing and delivering a purchased agent.

• New Postern is public as of this release: the v0.1 specification, a reference implementation, an entitlement check endpoint, and a generic runner image that turns a licensed token into a running agent. Incubator bundles now carry a Postern identity with an owner half that is frozen, because handles move. Container delivery stays pipeline only for now, and the distributor status page is the place to check whether licensing and delivery are healthy. Crew publishing remains with founding sellers ahead of general availability. In the builder, buyer setup answers now bridge into the runnable crew run, routing chips are derived from the crew's own step three prompts rather than declared separately, and step five shows which prompts reference each variable.

Contacting a Seller Becomes a Thread, and Search Covers the Whole Catalogue

Contacting a seller is now a thread both sides can reply to, a low rating opens that thread instead of posting straight to a listing, and post purchase follow ups ask one question you can answer with a single tap. Search and filters cover the whole catalogue, the homepage is rebuilt around reviewed and recommended listings, and sellers get a suggested price band, a category picker that reads the description they typed, and decimal prices. Accounts now say whether you are buying, selling, or both. Plus Retell flows as a product type, versioned legal documents with an email when they change, and profile backgrounds for everyone.

Skills Install Straight into Claude Code, and Publishing Becomes a Conversation

Skills you buy now install into Claude Code from a private feed of everything you own, added with a single command, refreshed as you buy and revoked when you refund. A public free feed opens qualifying skills to anyone.
