Ex-Linktree CRM lead open-sources Orbit: 130 MCP tools for Claude to gate marketing emails
CleanPucks · reddit · 2026-08-21
A developer with ten years of CRM/lifecycle experience at Linktree, Depop, Deliveroo and Trainline open-sourced Orbit, an MCP extension for Claude with 130 tools, 80 skills and 91 long-form guides.
The standout is the render gate: give it email HTML and it renders at 640px and 390px in a real browser engine, then measures what source can't show — computed contrast, tap targets under 44px, single-word last lines, and byte size vs Gmail's clipping limit. The author's own README example fails on his own brand indigo: white on #6366F1 at 13px is 4.47:1, three hundredths short of AA — a finding he deliberately left in.
Out of the box you also get a Gmail client simulator, calculators (cohort retention, sample size, RFM, LTV/payback), WCAG/dark-mode/GDPR lint, an MJML pipeline, and integrations with Braze, Iterable, Klaviyo, Mailchimp, Customer.io and SFMC. 80 downloads, 10 regular users.
