VibeCart MCP

VibeCart provides a generic MCP server for AI agents to interact with a trusted commerce layer. It supports listing products, retrieving product details, and creating Stripe Checkout sessions with server-side price resolution. It also offers durable cart management via a Neon-backed backend, allowing agents to create, read, update, and cancel multi-item carts with idempotent operations and optimistic version checks.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

VibeCart exposes a compact trusted-catalog and multi-item checkout toolset for generic MCP clients; UCP-aware clients use /ucp/mcp for durable cart/order protocol capabilities.

vibecart.create_checkout — Create a hosted Stripe Checkout session
Advertised by the server during the last successful anonymous check.
Open-world

Creates a hosted checkout URL for one or more trusted merchant-catalog products. Legacy productId + quantity input remains supported; new integrations should use items[]. VibeCart resolves all prices server-side. This can contact Stripe but never charges by itself; the customer must complete Stripe Checkout.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http vibecart-mcp https://vibecart.vercel.app/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add vibecart-mcp --url https://vibecart.vercel.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable vibecart-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "vibecart-mcp": {
      "url": "https://vibecart.vercel.app/mcp"
    }

}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start vibecart-mcp and inspect its tools.
VS Code configuration

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http vibecart-mcp https://vibecart.vercel.app/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
