Details
From the project READMECrowdin MCP by usefulapi
Manage your Crowdin localization projects, strings, and translations from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Crowdin API token.
Live endpoint: https://crowdin.usefulapi.io/mcp · Homepage: https://usefulapi.io/crowdin
Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://crowdin.usefulapi.io/mcp. - Claude Code:
claude mcp add --transport http crowdin https://crowdin.usefulapi.io/mcp, then run/mcpto log in. - VS Code: Add to VS Code.
- Cursor and other clients: add the URL as a remote MCP server:
{
"mcpServers": {
"crowdin": {
"url": "https://crowdin.usefulapi.io/mcp"
}
}
}
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Crowdin credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/crowdin/
On first connect you'll paste your Crowdin API token. It's validated, stored per-user, and scoped to you.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
