Server details

Identifier: dev.samva/mcp
Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified
Published: Sep 16, 2026

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to samva.dev, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Authenticated Samva MCP server for email work: sending transactional email, templates, delivery events and signed webhooks, plus public docs discovery.

What you can do: Discover Samva public documentation, cookbooks and agent plugins
Find and work with email templates, including TSX template projects
Send transactional email and connect auth email flows
Handle delivery events and verify signed webhooks
Look up package integrations and runnable examples
When to use it: Useful when an assistant helps build or operate Samva email integrations — transactional sends, auth email callbacks, template rendering and publishing, or webhook verification — and needs the current docs and templates at hand.
Requirements: A remote streamable HTTP endpoint at mcp.samva.dev; OAuth authentication is required. No environment variables or headers are declared. The README's local monorepo workflow (Bun, Turborepo) applies to the open-source repository, not to connecting the hosted server.

Before you install

Access is tied to an authenticated Samva account via OAuth, so the assistant acts with that account's permissions. Sending email and handling delivery or webhook events affect real recipients and production flows; review any send or publish action before it runs. The README notes the 0.x SDK line (0.33) is the only maintained integration target.

Installation

In SourceWeft

Open Samva MCP in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.samva%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Samva

Open-source packages, examples, cookbooks, and agent plugins for integrating Samva into real applications.

Use these to send transactional email, connect auth email flows, work with templates, handle delivery events, and verify signed webhooks. 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: 0.33. Workspace packages require samva@^0.33.0 as a peer and test against 0.33.0. Examples use samva@^0.33.0; copyable external import maps pin [email protected].

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.

Cookbooks

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

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.
