Build and run a business from your AI assistant, with hosting, payments, email and more built in.
Overview
Spark's remote MCP server lets an assistant plan, build, preview and publish small business sites and apps with hosting, payments, email and marketing built in.
- What you can do
- Plan and create projects: plan a new project one question at a time, then create it and start the first build
- Inspect projects: list projects with addresses and unpublished changes, read one project's pages, internal tools, setup progress and pending questions, and review recent publishes and requests
- Send requests and follow them: send a request about a project, a page or an internal tool with up to five files, follow the turn, answer Spark's questions or approvals, and stop a build
- Check and publish: view a preview screen at desktop or phone width, then publish the newest version
- Account and plan: see which account is signed in, its organizations, and remaining build credits
- When to use it
- Useful when you want an assistant to help you stand up and iterate on a small business site or app — booking pages, customer accounts, Stripe payments, customer email and marketing — without leaving the chat, and to check and publish the result.
- Requirements
- A remote server at mcp.spark.site using streamable HTTP with OAuth sign-in; no API key. A Spark account on any plan is needed, and payments or a custom domain require a paid plan. Building consumes the plan's build credits.
Installation
In SourceWeft
- Open Spark 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/io.github.PlusDocs%2Fspark/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.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Spark MCP
Build and run a business from your AI assistant with Spark: sites and apps with hosting, customer accounts, payments, email and marketing built into the platform. This is the official plugin for Spark's remote MCP server, for ChatGPT, Claude, Claude Code, Cursor, Codex and any other MCP client.
What Spark is
Spark is a platform for building and running a business. You describe what you want, and Spark designs it, writes the code and publishes it. A project is the whole business, and what it needs to run is built into the platform:
- Hosting on a
spark.siteaddress or your own domain. - Customer accounts: sign-in for your customers, and what each one has bought.
- Payments through Stripe: one-off sales and subscriptions, paid out to you.
- Email to your customers.
- Marketing: a marketing plan for the business and the content to go with it.
- Internal tools for running it, such as customer and payments dashboards, which Spark builds and changes like the site.
Through this server, your assistant works in a project's chat the way you would in Spark. It sends your requests, follows Spark while it works, brings Spark's questions and approvals back to you, looks at the preview and publishes.
What to expect.
- A change usually takes a few minutes, and a new project's first build about ten. The assistant waits for Spark and reports what it is doing meanwhile.
- Spark asks before some actions, such as deleting data. Your assistant shows you the question, and nothing happens until you answer.
- Messages your assistant sends appear in the project's chat in Spark, marked as sent from that assistant, so you can carry on in either place.
- Building uses the Build credits of your Spark plan, as it does in Spark.
Requirements
A Spark account, on any plan. The Free plan includes one-time credits for building, and you can publish on a spark.site address. Taking payments and using your own domain need a paid plan. See pricing.
You don't need an API key: you sign in with your Spark account the first time you use the server.
Install
ChatGPT. Open Plugins, select +, then Add custom MCP server. Name it Spark, enter https://mcp.spark.site as the server URL with OAuth authentication, and create it. In a chat, type @ and pick Spark. See OpenAI's guide.
Claude (claude.ai, desktop and mobile). Go to Customize → Connectors, select + Add, then Add custom connector. Name it Spark, enter https://mcp.spark.site, and select Continue, then Add. In a chat, turn it on under + → Connectors. On Team and Enterprise plans, an Owner adds it under Organization settings → Connectors and each member selects Connect. See Spark's guide.
Claude Code. Install the plugin, which adds the MCP server and the build-with-spark skill:
Then ask for a change, or run /spark:build-with-spark add a pricing page to my Harbor Tours site. To add only the MCP server: claude mcp add --transport http spark https://mcp.spark.site
Codex. Add this repository as a plugin marketplace, then install Spark.
Cursor and any other MCP client. Add the server to the client's MCP config:
On first use, the client opens Spark's sign-in. Sign in to Spark if you aren't already, then choose Connect.
Tools
In clients that support MCP Apps, such as Claude and ChatGPT, a project shows as a card. The card follows Spark while it works, shows its questions with their choices, and has Publish, Stop and Open in Spark. In Claude, after a change, it shows a picture of the part of the site that changed. Other clients get the same results as text.
Example prompts
- "Plan a new Spark project with me: a booking site for my pottery classes that takes payments."
- "What is Spark working on in my Harbor Tours project?"
- "Ask Spark to add a pricing page with our three class packages, then check it on a phone."
- "Ask Spark to email my customers about the new spring classes."
- "Send Spark this menu and ask it to put it on the home page: https://example.com/menu.pdf"
- "Publish Harbor Tours."
Notes
- Tools run as the Spark account that signed in, in that account's organizations.
- Clients may ask you to confirm each request that changes a project, and each publish.
- To disconnect an assistant, open Account settings in Spark and go to Connected assistants.
- Spark hosts the server. This plugin runs no local code.
