What it does

Free, open-source skill, CLI, and MCP server for email platform migrations. It maps source exports to destination imports and flags the manual-review gaps — the segments and flows that don't translate cleanly — before your agent starts writing. The point is simple: your list and your flows are yours. Leaving should never be the thing that keeps you stuck.

Free, open source skill, CLI, and MCP server for planning email platform migrations. Check source exports, destination imports, and manual-review gaps before your agent writes.

mailexodus gives your agent the migration plan: what the source can export, what the destination can import, and which flows need human review. Not a checklist. A skill plus a prompt. reads from: klaviyo · customer.io · mailchimp · activecampaign · brevo · mailerlite · hubspot · 29 + more The category ships migration “tools” that are really checklists. Export this, rebuild that, good luck with the automations. mailexodus tells your agent what the source can export, what the destination can import, and how to map the portable objects between them. The parts that can be safely automated, are; the rest is flagged before anyone writes. A 40-item list and a weekend of copy-paste. Your flows get…from mailexodus.com

  Open sourcing my email sending startup2019 · ▲38

  Hi all, I've posted a few times here about Maildown, a startup that I've been trying to validate lately. Due to lack of time to focus on this, I've taken the decision to abandon the project as a startup, but to make it available as an open source solution instead. The (still very basic) github repository is here: https://github.com/chris104957/maildown Maildown now exists as a simple CLI wrapper for Amazon SES which bakes in Markdown and styling support, making it much easier to get transactional mails up and running in any project Thanks for looking, Chris

  MCPGod: Fine-grained control over MCP clients, servers, and tools2025 · github.com · ▲37

  Hey everyone, I've wanted an easy way to control which mcp server tools are available to clients. So for example, I might want a gmail server to only expose the read tool (but not send, delete etc). I figured if I create a cli for spawning mcp servers, I could intercept the stdin, stdout, stderr etc and modify what the clients see when they are making calls to list tools, resources, and prompts. Well it worked! In the initial version you can easily add a server to claude with a safe list of tools: npx -y mcpgod add @modelcontextprotocol/server-everything --client claude --tools=echo,add…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
