📄 Description

Summary

  • Adds a dedicated landing page for the OAuth-authenticated remote MCP server hosted at api.smith.langchain.com/mcp (US) and eu.api.smith.langchain.com/mcp (EU). Covers OAuth 2.1 + dynamic client registration, quickstart configs for Claude Code and Cursor, the tool surface, and re-auth instructions.
  • Adds a deprecation <Warning> to the existing standalone-server page (langsmith-mcp-server.mdx) directing Cloud users to the new page. Notes explicitly that the Remote MCP is SaaS-only for now and that the standalone server remains the supported path for self-hosted LangSmith.
  • Wires the new page into the "Viewing & managing traces" section of the sidebar.

The standalone server's content (PyPI install, Docker, headers, etc.) is intentionally preserved on the existing page since it's still the supported option for self-hosted deployments.

Release Note

Documented the new OAuth-based LangSmith Remote MCP at api.smith.langchain.com/mcp and clarified that the standalone langsmith-mcp-server package is now the self-hosted-only path.

Test Plan

  • Preview the new langsmith-remote-mcp page in the docs build and confirm rendering of the <Note> and <Warning> callouts.
  • Verify the deprecation <Warning> on the standalone-server page renders and links resolve to the new page.
  • Confirm the new page appears in the sidebar under "Viewing & managing traces" → above the standalone-server page.
  • Verify the Claude Code config snippet works against api.smith.langchain.com/mcp (OAuth flow completes; tools surface as mcp__langsmith__*).
