Overview

AI-generated overview

Remote MCP endpoint for Agent-Native Mail, an email client that lets an assistant prioritize email, draft replies and follow up.

What you can do
  • Prioritize and triage incoming email
  • Draft replies to messages
  • Follow up on conversations
  • Work inside an email client that also offers keyboard shortcuts and AI triage
When to use it
Useful when you want an assistant to help sort through a mailbox, draft responses and keep track of follow-ups from within an Agent-Native Mail account rather than a generic mail server.
Requirements
A remote MCP endpoint at mail.agent-native.com over streamable HTTP; OAuth sign-in is required. No environment variables or headers are declared.
Before you install
The server requires OAuth access to a mail account, so the assistant can read and act on email content; drafting replies and follow-ups may send or change data in the mailbox. The manifest lists no tools, so review the granted scopes before connecting.

Installation

In SourceWeft

  1. Open Agent-Native Mail in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/io.github.BuilderIO%2Fagent-native-mail/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

[Agent-Native: The agentic application framework]

Agent-Native

Agent-Native is an open-source TypeScript framework for building agents that pair autonomous work with a purpose-built UI. Define each capability once as an action: the agent uses it as a tool, and the UI calls it from code.

Quick start

bash
npx --yes @agent-native/core@latest create my-agent --standalone --template chat

Follow the getting started guide for a full intro to the framework.

Why build agents with UIs?

Coding agents work with more than a text box. Their environment provides context, tools, files, tests, and previews that make their capabilities and results visible.

Knowledge work needs that same kind of environment. A UI shows what an agent can do and gives people familiar ways to inspect, edit, approve, and share its work.

How Agent-Native works

  • Shared actions. The agent calls each capability as a tool, and the UI calls it from code. Both paths use the same validation, permissions, and implementation.
  • Shared data. Work done by the agent appears in the UI, and work done in the UI is available to the agent.
  • Shared application state. The agent receives relevant UI state, such as the current page, selected record, or active view.

The agent does not click through the UI. It works through the same action layer as the UI.

Example: a shared action

Create actions/hello.ts:

ts
import { defineAction } from "@agent-native/core/action";import { z } from "zod";
// One action powers every app surface: UI, agent, HTTP, MCP, A2A, and CLI.export default defineAction({  description: "Return a friendly greeting.",  schema: z.object({    name: z.string().default("world").describe("Name to greet"),  }),  http: { method: "GET" },  run: async ({ name }) => {    return { message: `Hello, ${name}!` };  },});

The agent receives hello as a tool. React calls the same function with useActionQuery("hello", { name: "Alex" }). Agent-Native also exposes it through HTTP, MCP, A2A, and the CLI.

Included

  • Agent chat: Let people delegate work, ask questions, and review results in the same UI.
  • Authentication and permissions: Control who can access and change shared work.
  • Skills and memory: Give agents reusable expertise and persistent context.
  • Automations: Run agent work on schedules or events.
  • Agent teams: Delegate work to specialist agents in the same workspace or across connected agents.
  • PostgreSQL backend: Use PostgreSQL in production and PGlite for local development on any Nitro-compatible host.

Example: edit a running app visually

Use /visual-edit in Claude Code to edit a running app on a canvas instead of prompting for each small UI nudge. Compare live pages together, then ask Claude to apply the chosen edits to your source. For example:

text
/visual-edit the onboarding flow, plus home at every breakpoint

Review the onboarding screens alongside Home at desktop, tablet, and mobile sizes, adjust a button's color or spacing directly, then ask Claude to apply the pending edits to your source. See the Visual Edit guide for the full walkthrough and sharing details.

Bring your LLM, SQL database, tools, and infrastructure. Everything you build stays yours.
