Temway MCP Server

Let your AI assistant design beautiful emails & layouts — in your Temway workspace.

A Model Context Protocol server that turns Claude, ChatGPT, Cursor and friends into a visual email & layout authoring studio.

Getting Started · Clients · Tools · Temway

Temway is a visual builder for emails and layouts. This MCP server exposes your Temway workspace to any MCP-compatible AI client: the model reads your brand tokens, drafts a promo / newsletter / welcome email, previews it, publishes it, and even sends a test — all through natural language. No code, no drag-and-drop, no copy-pasting HTML.

It is a hosted remote MCP server. You point your client at a URL with an API key (or OAuth for web clients) — there is nothing to install, build, or run locally. The server speaks the MCP Streamable HTTP transport.

🔒 No source here? Correct. This is the public onboarding repo for the

Temway MCP server. The server is operated by Temway and runs at

https://mcp.temway.com/mcp. This repo holds client configuration, tool

reference, and connectivity helpers. Report issues / request tools in

How it works

Your AI client (Claude / ChatGPT / Cursor / Desktop)

└─ MCP over HTTPS → https://mcp.temway.com/mcp Authorization: Bearer tmw_live_… ← API key (or OAuth token for web connectors) └─ Temway public API → your workspace

The model authenticates per-request, then drives your workspace through brand-aware templates, block mutations, layout artwork, live previews, and publishing.

Getting started

1. Get an API key

API keys are minted by a team admin in the Temway dashboard. The key:

• starts with tmw_live_…
• is bound to one workspace
• carries scopes (emails:read, emails:write, layouts:read, layouts:write) that gate which tools succeed

Store it securely — it's shown once.

2. Point your client at the server

The endpoint and a ready-to-paste config for each client are in examples/. The short version:

# Claude Code

claude mcp add --transport http temway https://mcp.temway.com/mcp \ --header "Authorization: Bearer tmw_live_xxxxxxxxxxxxxxxx"

That's it. The workspace is derived from the key.

3. Ask your assistant

*"Create a promo email for our summer sale, 25% off, brand colors, a big CTA

button, preview it, then publish it."*

The model will get_branding → create_email → apply_template → update_block → preview_email_web → publish_email for you.

Configure your client

The Temway server speaks the Streamable HTTP transport. Pick your client:

Authentication

Two credential types — both resolve onto the same workspace context:

• `tmw_live_…` API keys — for desktop & programmatic clients (Claude Code, Claude Desktop, Cursor, scripts). Sent as Authorization: Bearer tmw_live_…. The workspace is derived from the key. Scope-bound.
• OAuth 2.1 — for hosted web connectors (claude.ai, ChatGPT) that reject static keys. No header to paste — the user signs in and picks a workspace on the consent screen; the connector receives its own short-lived token (PKCE / S256). Just enter the URL https://mcp.temway.com/mcp.

Tools

The server exposes 58 tools across five groups. Reads need a *:read scope; mutations need *:write.

Discovery & context — brand tokens, schemas, catalogs

Emails — author, mutate, preview, publish, send

Layouts — free-form pixel-perfect artwork canvas

Note: layouts rasterize to a single PNG when embedded in an email (text

not selectable). Author readable/clickable content as email blocks instead.

Concurrency locks — prevent clobbering on shared resources

acquire_* / get_*_lock_status / refresh_*_lock / release_*_lock / force_release_*_lock for both email and layout resources.

Block/element mutations are not atomic — never fire two on the same resource in parallel. Acquire the edit-lock first on shared resources.

Search & fetch

A typical authoring flow

get_branding

→ create_email { name: "Spring sale" } → apply_template { template: "promo" } # brand-aware starter → update_block / add_block # tweak copy, CTA, colors → preview_email_web # fast preview (preferred) → publish_email # renders + marks published → test_send_email { to: "me@example.com" } # optional real send

Environment variables

The hosted endpoint is fully managed — most users never touch env vars. They only matter if you self-host or run the stdio transport.

Connectivity check

Verify the endpoint is reachable from your network before wiring up a client:

node scripts/healthcheck.mjs

→ OK 200 OK (926ms)

→ ✓ Temway MCP endpoint is reachable.

(npx temway-mcp-healthcheck once published, or npm run healthcheck.)

Self-hosting

This repo does not contain server source. If you need to run the server yourself (on-prem, air-gapped, custom auth), contact hi@temway.com or open an issue.

FAQ

Is this open source?

The server is operated by Temway (source currently private). This repo is the public integration surface: client configs, tool reference, and helpers, published under the MIT license so you can copy configs freely.

Do I need to install Node / npm / anything?

No. The hosted remote transport means your client connects over HTTPS by URL — nothing runs locally. The optional healthcheck.mjs needs Node ≥ 18.17.

Which client should I use?

For local/CLI work: Claude Code or Cursor. For no-install browser use: claude.ai or ChatGPT with the OAuth connector. All configs are in examples/.

How are my emails protected from the model?

Credentials are scope-bound per key (*:read / *:write). Reads never mutate; every mutation is explicit. Narrow scopes to a read-only key for safe browsing.
