Claude Desktop App with HTTP-with-SSE-transport?

[dforsber]

Configuring the MCP servers into Claude Desktop App currently only show how to add the stdio protocol versions.
==> How do I add MCP server using HTTP with SSE transport? Or is it not yet supported?

[dsp-ant]

This is not supported at the moment.

Here is a great workaround while we wait for official support: https://developers.cloudflare.com/agents/guides/remote-mcp-server/#connect-your-remote-mcp-server-to-claude-and-other-mcp-clients-via-a-local-proxy

[tadasant]

Remote MCP is now supported (for certain plans): https://support.anthropic.com/en/articles/11175166-about-custom-integrations-using-remote-mcp

[julien-c]

do you have it in the Claude Max plan? or is it also geographically-restricted?

Not really. It's quite different implementation. I would expect to be able to use local SSE too, with the regular MCP configuration, similar to other tools like Cursor or VSCode.

I just wrote a stdio to http sse gateway with example MCP server and client as well. The server exposes DuckDB database and allows Claude to run queries on it.

[shenli]

It works for me. Thanks!

[hasani114]

Is there any update on this? I am able to use this on LibreChat and Cursor now but it doesn't work on Claude Desktop app

[SamFold]

Are SSE Servers supported with Claude Desktop yet? If so, what does the configuration look like?

[QuantGeekDev]

I don't think they are unfortunately, I'm looking for the same

[dforsber]

Updated the README in the example stdio to HTTP SSE bridge:
https://github.com/boilingdata/mcp-server-and-gw

Shouldn't be too hard to convert to python if you prefer that. Naturally, you can run your server in Python if you like.

[dacay]

Could you please at least state whether this is on the roadmap or not?

I am working on a somewhat complex MCP server and currently, it only supports HTTP SSE due to some OS-level permission issues. If it was an Open Source project, I'd love to contribute as well :)

Claude Desktop App with SSEServerTransport, what does the configuration look like?

[QuantGeekDev]

Like nothing. Anthropic hasn't really added any of that stuff yet. Just the stdio tool calling. Hope it helps

I'm not sure if I'm shocked or that it is obvious for me.
I developed MCP server with the problematic SSE definition, feeling Anthropic didn't really got into supporting any remote MCP servers properly. I bumped into many issues and overcome them, just to find out Claude app doesn't even support this.
Since Claude app wasn't my go-to client, it is fine, but it feels lame.

This worked for me: https://developers.cloudflare.com/agents/guides/test-remote-mcp-server/#connect-your-remote-mcp-server-to-claude-desktop-via-a-local-proxy

[CyrilPeponnet]

⚠️ self promotion

We made Minibridge to support that use case for free and more https://github.com/acuvity/minibridge

[mzhadigerov]

any updates on this?

[adstastic]

It's working from Claude Code with FastMCP's SSE mode:

mcp.run(transport="sse", host="127.0.0.1", port=8000)

[pannous]

But how do you specify sse in claude_desktop_config.json ?

[renato-umeton]

Any update on this?

[pgangwani]

WHy is MCP creator so behind for this support?

[tadasant]

Remote MCP support in Claude is now documented here: https://support.anthropic.com/en/articles/11175166-about-custom-integrations-using-remote-mcp

[jiri-prokop-pb]

Yes, but it sucks. I would expect support similar to other tools where you can have local MCPs that run as servers.

As I mentioned here: https://github.com/orgs/modelcontextprotocol/discussions/16#discussioncomment-13035353

"Custom connectors" don't work on localhost with http, since Claude Desktop requires that the URL start with https. Could you please allow http on localhost so that people can easily run their own servers?

[eng-marani]

I'm facing the same exact issue.
I was looking to use Claude desktop to test my own MCP server running locally on Http (not https) but as far as i know the "command" parameter is mandatory, and i've found no way of adding my MCP server as local tools.
It seem that someone have succeed using a "local proxy", do anyone know how to setup one of these ?

Using ngrok should work. It is much easier to set up compared to a reverse proxy. That would require something like Nginx and configuration to use a self-signed certificate.

[kerryjiang]

Yes, same problem here. But According to Claude's doc, http is supported.
https://code.claude.com/docs/en/mcp

[DePasqualeOrg]

It's true, they have examples with http://localhost on that page, but it doesn't work in Claude Desktop. @bcherny, @ThariqS, any chance you could pass this on to someone to get this fixed?

[eng-marani]

In order to test your http MCP server using claude desktop, you need to use this configuration, that is unnecessary if you have the "pro" paied version, but mandatory with the free version, as far as the "command" keyword is mandatory.

Example of claude_desktop_config.json:

{
  "mcpServers": {
    "MyMCP-server": {
      "command": "npx",
      "args": ["mcp-remote", "http://localhost:3353/sse"]
    }
  }
}

Use your MCP url address with proper port as needed.
Hope this helps,
Paolo

[swiru95]

ok but what about kind of custom headers and auth requirements?

[DePasqualeOrg]

I created this package to bridge local MCP servers running on HTTP to stdio for Claude Desktop, which rejects URLs starting with http:// even on localhost.

https://github.com/DePasqualeOrg/mcp-http-stdio-bridge

You can use it like this in claude_desktop_config.json:

{
  "mcpServers": {
    "My Server": {
      "command": "npx",
      "args": ["-y", "@depasquale/mcp-http-stdio-bridge", "--url", "http://localhost:8080/mcp"]
    }
  }
}

[swiru95]

What if I need to provide headers, auth etc?:D
