MCP server for Crowdin — projects, files, strings, translation progress, tasks, and members.
The publisher's own server: Ably MCP by usefulapi
Hosted MCP server for Crowdin that lets an assistant browse localization projects, strings, tasks and translation progress, and add strings or translations.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fcrowdin/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

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.

On first connect you'll paste your Crowdin API token. It's validated, stored per-user, and scoped to you.
