Common questions

Is Samva MCP safe?

It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed today, and the latest version (1.1.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

In the same category: Inbox Zero, Agent-Native Chat, draw.io

Samva

Packages, examples, cookbooks, and agent plugins for building on Samva, the email and WhatsApp API.

Samva takes the routine customer emails off a small business: an AI assistant answers them and asks before it sends. Developers and agent builders build on the same platform. Use this repository to send transactional email, connect auth email flows, work with templates, receive replies and delivery events as signed webhooks, and give an agent its own mailbox. Ask questions about the code on DeepWiki.

Structure

  • packages/* — package integrations (@samva/*).
  • examples/* — complete, runnable example apps.
  • cookbooks/*.md — documentation-first, copy-pasteable recipes.
  • plugins/* — coding-agent plugins and public documentation.

While Samva is 0.x, the maintained integrations support only the current SDK minor: 0.35. Workspace packages require samva@^0.35.0 as a peer and test against 0.35.0. Examples use samva@^0.35.0; copyable external import maps pin samva@0.35.0.

Package integrations

Agent plugins

  • samva — OpenAI Codex and Cursor packaging for the canonical hosted MCP server and Samva agent skill.
  • Samva in ChatGPT — the published ChatGPT plugin is a separate listing from the Codex and Cursor package; the guide covers connecting one organization and a read-only first check.

Cookbooks

Integrations land as individual pull requests. See CONTRIBUTING.md to propose or build one.

Examples

  • astro-email — Astro Action and JSON endpoint on Cloudflare Workers.
  • better-auth-nextjs — Better Auth callbacks in a Next.js App Router application.
  • clerk-webhook — Clerk webhook verification and transactional email in Next.js.
  • effect-sdk — Email sends through the samva/effect SDK entrypoint.
  • email-sdk — Email SDK sends through the provider-owned Samva community adapter.
  • hono-cloudflare-workers — Hono Worker with a JSON email endpoint.
  • inbound-email-replies — receives an inbound reply, verifies the signed webhook, and answers in-thread.
  • mailbox-agent — an agent that follows a mailbox event stream and replies in approval mode, plus the same behavior as an @samva/mailbox webhook extension.
  • nextjs-transactional — App Router contact form plus /api/send route handler using the Samva SDK.
  • react-email-samva — React Email rendering and delivery through Samva.
  • supabase-auth-hook — Supabase Auth Send Email Hook implemented as an Edge Function.
  • sveltekit-transactional — SvelteKit form action and raw email endpoint.
  • tanstack-start-transactional — TanStack Start server function and server route.
  • tsx-template-samva — a defineTemplate email project: check, render, preview, and publish with the Samva CLI.

Contributing

Contributions are welcome — see CONTRIBUTING.md for local setup, package conventions, and how to propose a new integration. Maintainers use the Tegami release flow for package versions, changelogs, npm publication, tags, and GitHub Releases. GitHub Actions publishes; merging the Version Packages pull request is the human gate.
