Introduction

OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Crowdin with authentication management handled for you. You can execute actions on Crowdin via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.

Why use Composio?

Apart from a managed and hosted MCP server, you will get:

  • Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
  • Handling Large tool responses out of LLM context to minimize context rot.
  • Dynamic just-in-time access to 20,000 tools across 850+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.

How to install Crowdin with OpenClaw

Using Composio API Key and Setup Prompt

Copy the setup prompt from the OpenClaw dashboard
  • Run it in your OpenClaw chat interface.
  • Authenticate Crowdin from the dashboard
  • Go back to your OpenClaw interface and start asking questions.

Using OpenClaw/Composio Plugin

1. Install OpenClaw Composio plugin

bash
openclaw plugins install @composio/openclaw-plugin

2. Copy the API Key from dashboard.composio.dev

3. Setup OpenClaw Config

openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"

4. Restart OpenClaw

openclaw gateway restart

5. Go to your chat interface and start asking questions.

6. When prompted, authenticate the app and you're all set.

How It Works

The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.

If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.

What is the Crowdin MCP server, and what's possible with it?

The Crowdin MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Crowdin account. It provides structured and secure access to your localization projects, so your agent can manage branches, organize files, label content, automate webhooks, and orchestrate translation workflows on your behalf.

  • Branch and project management: Easily have your agent create, delete, or organize Crowdin projects and branches to streamline new releases or features.
  • Dynamic file handling: Let your agent add new files to projects, ensuring your translation assets are always up to date and properly organized by branch or directory.
  • Labeling and content categorization: Direct your agent to create, assign, or remove labels on resources and strings, helping you segment and track translation tasks with precision.
  • Workflow automation with webhooks: Automate your translation process by having the agent set up or remove webhooks for real-time notifications and integrations.
  • Resource cleanup and maintenance: Empower your agent to delete obsolete branches, labels, webhooks, or entire projects, keeping your Crowdin workspace clean and focused.

Conclusion

You've successfully integrated Crowdin with OpenClaw using Composio plugin. Now interact with Crowdin directly from your terminal, Web UI, or any messenger app using natural language commands.

Key benefits of this setup:

  • Seamless integration across TUI, Web UIs, and Messenger apps like Telegram, WhatsApp, Slack, etc.
  • Natural language commands for Crowdin operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 850+ apps for cross-app workflows
  • Programmatic tool calling for complex tool chaining

Next steps:

  • Try asking OpenClaw to perform various Crowdin operations
  • Explore cross-app workflows by connecting more toolkits like Calendar, Slack, Notion, etc.
  • Build complex automation scripts that leverage OpenClaw's 24/7 running capabilities

How to build Crowdin MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and Crowdin MCP?

With a standalone Crowdin MCP server, the agents and LLMs can only access a fixed set of Crowdin tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Crowdin and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with OpenClaw?

Yes, you can. OpenClaw fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Crowdin tools.

Can I manage the permissions and scopes for Crowdin while using Tool Router?

Yes, absolutely. You can configure which Crowdin scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Crowdin data and credentials are handled as safely as possible.
