Common questions
Is Foundations Elements safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

Foundations Elements MCP
Public install package for the Foundations Elements remote MCP server.
- MCP URL: https://foundations.tensegrity.works/mcp
- Product / waitlist: https://tensegrity.company/elements
- Docs: https://foundations.tensegrity.works/docs
- Privacy: https://tensegrity.company/privacy
- Terms: https://tensegrity.company/terms
- Support: support@tensegrity.company
This repository is the free plugin / registry metadata. The Worker implementation stays private. Access to catalog tools requires a Foundations account (OAuth via https://auth.tensegrity.works).
Publisher (marketplaces): GitHub org Tensegrity-Systems. Canonical repo: https://github.com/Tensegrity-Systems/foundations-elements-mcp (GitLab remains a staging mirror).
What you get
Cursor / Agent plugin that points at the remote MCP endpoint, plus server.json for the official MCP Registry.
Tools include search, kind lists, and spec fetch (elements_search, elements_list, elements_get, and related). See server instructions after connect.
Install
Cursor
- Install this plugin from the Marketplace when published, or load the repo as a local plugin.
- Complete OAuth when Cursor prompts for Foundations sign-in.
- Request access at https://tensegrity.company/elements if you do not have an account.
mcp.json already points at:
https://foundations.tensegrity.works/mcpClaude
Add a custom connector with the same HTTPS URL, then sign in with OAuth. Directory listing will use this package’s branding and docs links.
VS Code / Copilot
Configure an HTTP MCP server with the URL above (after Official / GitHub MCP Registry publication).
Official MCP Registry
server.json declares a remote Streamable HTTP server. Preferred registry name (after domain ownership proof on tensegrity.works):
works.tensegrity/foundations-elementsPrivacy
Foundations account sign-in and MCP usage are covered by the company privacy policy:
https://tensegrity.company/privacy
This install package does not collect data on its own; it only points clients at the remote MCP URL. Support: support@tensegrity.company.
License
MIT for this install package. Foundations Elements content and API remain proprietary; see https://tensegrity.company/terms and https://foundations.tensegrity.works/terms.
Channel note
Paid HTTP (x402) lookups use GET /mcp/elements/search. That is a separate agent-catalog path, not this IDE MCP plugin.
