listing.about

Connects an assistant to Smartling, a translation management and localization platform. It is meant for working with translation projects, jobs, files and strings in your Smartling account.

It runs as a hosted streamable HTTP endpoint at https://mcp.smartling.com/mcp. Users sign in with OAuth, so no API key needs to be pasted into the client. The tool list is not published ahead of sign-in.

listing.can

  • Work with Smartling translation projects
  • Manage translation jobs
  • Handle content files in Smartling
  • Look up and work with translatable strings

listing.tools

listing.notools.oauth

listing.prompts

  • List my Smartling projects

  • Show the open translation jobs in my Smartling account

  • Find the strings in my project that still need translation

  • Check the status of the files in my latest Smartling job

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport http smartling https://mcp.smartling.com/mcp
  1. Start Claude Code, type /mcp, pick smartling and choose Authenticate. A browser window opens for the Smartling sign-in.

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

Claude Desktop

  1. Open Settings → Connectors and click Add custom connector.
  2. Name it Smartling and paste this URL:
https://mcp.smartling.com/mcp
  1. Click Add, then Connect, and sign in when Smartling 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

  1. Open the connector form on claude.ai. This button fills in the name and URL for you:
  1. Check that the URL reads https://mcp.smartling.com/mcp and click Add.
  2. Click Connect and sign in when Smartling asks.

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

ChatGPT

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

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

Cursor

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

mcp.json
{
  "mcpServers": {
    "smartling": {
      "url": "https://mcp.smartling.com/mcp"
    }
  }
}

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

VS Code

Or from a terminal:

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

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

.vscode/mcp.json
{
  "servers": {
    "smartling": {
      "type": "http",
      "url": "https://mcp.smartling.com/mcp"
    }
  }
}

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

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "smartling": {
      "serverUrl": "https://mcp.smartling.com/mcp"
    }
  }
}
  1. 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 smartling --url https://mcp.smartling.com/mcp
codex mcp login smartling

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

config.toml
[mcp_servers.smartling]
url = "https://mcp.smartling.com/mcp"

Gemini CLI

gemini mcp add --transport http smartling https://mcp.smartling.com/mcp

Then, inside Gemini CLI, run /mcp auth smartling 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": {
    "smartling": {
      "type": "http",
      "url": "https://mcp.smartling.com/mcp"
    }
  }
}

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.smartling.com/mcp.

listing.faq

Can I paste mcp.tc/i/smartling into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://mcp.smartling.com/mcp, so your client talks to Smartling 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 Smartling need an API key or a sign-in?

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

Is Smartling a remote or a local server?

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

What can Smartling do?

You can work with Smartling translation projects, manage translation jobs and handle content files in Smartling.

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 Smartling'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.
