Tseha MCP Server
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.
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:
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
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.
