How do I connect the LangChain MCP server to Claude?

The registry lists a hosted endpoint at https://modevc.com/api/mcp/chart-langchain-alternatives-downloads-share. Check the publisher's authentication and client requirements, then add the endpoint as a custom connector in Claude and complete any sign-in it requires.

In Claude Code, run:

claude mcp add --transport http langchain https://modevc.com/api/mcp/chart-langchain-alternatives-downloads-share

Does the LangChain MCP server work with ChatGPT?

A hosted endpoint is available at https://modevc.com/api/mcp/chart-langchain-alternatives-downloads-share. ChatGPT needs a compatible remote transport and authentication flow, and your account or workspace must allow custom MCP connections. Confirm those requirements with the publisher before connecting.

How do I add it to Cursor?

Start with this remote endpoint in .cursor/mcp.json in your project, or ~/.cursor/mcp.json for every project. Add any authentication fields required by the publisher:

{
  "mcpServers": {
    "langchain": {
      "url": "https://modevc.com/api/mcp/chart-langchain-alternatives-downloads-share"
    }
  }
}
