Q: Is Stack Overflow a remote or a local server?

Remote. Stack Overflow hosts it at https://mcp.stackoverflow.com, and it speaks Streamable HTTP. There's nothing to install.

listing.about

Connects an assistant to Stack Overflow's knowledge base. It can search technical questions and answers and retrieve full threads, including accepted solutions and comments, so answers are grounded in community-verified content.

It runs as a hosted streamable HTTP endpoint at mcp.stackoverflow.com. Users sign in with a Stack Overflow account through OAuth. The README says the beta server is limited to 100 calls per day per user.

Claude Code

Run this in a terminal, in your project folder:

claude mcp add --transport http stack-overflow https://mcp.stackoverflow.com

Start Claude Code, type /mcp, pick stack-overflow and choose Authenticate. A browser window opens for the Stack Overflow sign-in.

Add --scope user to make it available in every project, not just this one.

Claude Desktop

Open Settings → Connectors and click Add custom connector.
Name it Stack Overflow and paste this URL:

https://mcp.stackoverflow.com

Click Add, then Connect, and sign in when Stack Overflow asks.

Claude Desktop's JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

claude.ai

Open the connector form on claude.ai. This button fills in the name and URL for you:

Add to claude.ai a11y.new_tab

Check that the URL reads https://mcp.stackoverflow.com and click Add.
Click Connect and sign in when Stack Overflow asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

ChatGPT

On chatgpt.com, open Settings → Security and login and turn on Developer mode.
Go to chatgpt.com/plugins and click + to create an app for a remote MCP server.
Paste https://mcp.stackoverflow.com as the server URL and choose OAuth. ChatGPT sends you to Stack Overflow to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

Cursor

Add to Cursor a11y.new_tab

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json

{
  "mcpServers": {
    "stack-overflow": {
      "url": "https://mcp.stackoverflow.com"
    }
  }
}

Cursor shows Needs login next to the server. Click it to sign in.

VS Code

Install in VS Code a11y.new_tab

Or from a terminal:

code --add-mcp '{"name":"stack-overflow","type":"http","url":"https://mcp.stackoverflow.com"}'

Or commit it to the repo in .vscode/mcp.json:

.vscode/mcp.json

{
  "servers": {
    "stack-overflow": {
      "type": "http",
      "url": "https://mcp.stackoverflow.com"
    }
  }
}

VS Code asks you to sign in the first time the server starts.

Devin Desktop

Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):

mcp_config.json

{
  "mcpServers": {
    "stack-overflow": {
      "serverUrl": "https://mcp.stackoverflow.com"
    }
  }
}

Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add stack-overflow --url https://mcp.stackoverflow.com
codex mcp login stack-overflow

Or edit ~/.codex/config.toml directly:

config.toml

[mcp_servers.stack-overflow]
url = "https://mcp.stackoverflow.com"

Gemini CLI

gemini mcp add --transport http stack-overflow https://mcp.stackoverflow.com

Then, inside Gemini CLI, run /mcp auth stack-overflow to sign in.

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI's settings file.

{
  "mcpServers": {
    "stack-overflow": {
      "type": "http",
      "url": "https://mcp.stackoverflow.com"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://mcp.stackoverflow.com.

listing.faq

Can I paste mcp.tc/i/stack-overflow into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://mcp.stackoverflow.com, so your client talks to Stack Overflow directly. The sign-in token only works there anyway. The quick link is for sharing: it opens this page, with setup steps for every client.

Does Stack Overflow need an API key or a sign-in?

Yes, you need a Stack Overflow account. The first time your client connects, it opens Stack Overflow's sign-in page. The token goes straight to the server's own URL, never through mcp.tc.

Is Stack Overflow a remote or a local server?

Remote. Stack Overflow hosts it at https://mcp.stackoverflow.com, and it speaks Streamable HTTP. There's nothing to install.

What can Stack Overflow do?

You can search Stack Overflow technical questions and answers, retrieve full threads with accepted solutions and comments and ground coding answers in community-verified content.

Which clients can use it?

Any client that supports remote MCP servers: Claude Code, Claude Desktop, claude.ai, ChatGPT in developer mode, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. The setup steps cover each one.

Who wrote this page?

mcp.tc's robot read Stack Overflow's own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can't confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
