Tseha

Serves your design system and coding standards to coding agents, so they stop guessing.

Tseha is a hosted, remote MCP server. Point your coding agent at it and the agent reads your real component APIs, design tokens and coding standards instead of inventing them.

• Website: https://tseha.io
• Documentation: https://tseha.io/docs
• MCP endpoint: https://tseha.io/mcp (Streamable HTTP)
• Official MCP Registry name: io.tseha/tseha

This repository holds the published server.json manifest and the connection documentation. Tseha itself is a hosted commercial service and its source is not open; there is nothing to install or build here.

Quick start

Add a .mcp.json to the root of your repository:

{
  "mcpServers": {
    "tseha": {
      "url": "https://tseha.io/mcp"
    }
  }
}

That is the whole configuration. On first connection the agent opens an OAuth sign-in in your browser. Approve it once and the agent is connected.

Other clients

Client	Where the config lives
Claude Code	.mcp.json in the project root, or claude mcp add --transport http tseha https://tseha.io/mcp
Cursor	.cursor/mcp.json (per project) or ~/.cursor/mcp.json (global)
VS Code / GitHub Copilot, and any other MCP client	point at https://tseha.io/mcp over the HTTP transport

Cursor plugin

This repository is also packaged as a Cursor plugin (.cursor-plugin/plugin.json plus mcp.json), so Cursor can install the connection for you instead of you editing a config file. Install it from Cursor Settings -> Plugins, or add the repository by hand from https://cursor.directory/plugins.

Authentication

OAuth 2.1 with PKCE (S256). There is no API key to paste. Tseha publishes the standard discovery documents — /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource (RFC 9728) — and supports both Dynamic Client Registration and Client ID Metadata Documents, so compliant clients configure themselves.

The issued token is scoped to your organization and your role. The MCP surface is read-only for every role. Writes happen only in the Tseha admin panel.

Tools

All nine tools are read-only. Every tool except list_projects takes a project_id, which list_projects returns.

Tool	What it returns
list_projects	The projects in your organization, each with id, name and framework. Call this first — the id is required by every other tool.
list_packages	The component packages assigned to a project, with version, and which one is active.
list_components	Every UI component in the project's design system: name, source package, import path, intended use.
get_component	The full spec for one component: import path, props schema, usage example, anti-patterns, when-to-use notes, Figma spec, dependencies.
search_components	Components ranked by description, for finding one by need rather than by name.
get_style	Style metadata for a design token collection.
get_style_tokens	Design tokens by category: color, typography, spacing, radius, shadow, blur, or all.
get_standards	Your organization's development standards, by section (global, react, nextjs, …).
get_component_updates	What changed between the installed version of a component and the current one.
