Common questions

Is Samva MCP safe?

It passed 1 of 1 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 –, and the latest version (1.0.0) reached the registry 2 months ago.

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 in developer mode.

What can I use instead?

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

@samva/better-auth — Better Auth email callbacks powered by Samva.
@samva/email-sdk — Provider-owned Samva community adapter for Email SDK.

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.
