How to integrate Lokalise MCP with Hermes

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows. This guide explains the easiest and most robust way to connect your Lokalise account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Lokalise with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Lokalise

Ask your agent to connect to Lokalise, or simply request any Lokalise-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Lokalise connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Lokalise or request any Lokalise-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Lokalise MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Lokalise account. It provides structured and secure access to your localization projects, branches, languages, keys, translations, and audit logs, so your agent can explore projects, manage keys, review translations, update localized content, and inspect team activity on your behalf.

  • Project and branch discovery: Have your agent list available localization projects and their branches so you can quickly find the content you need.
  • Language and translation review: Instruct your agent to check configured project languages and find translations by language, review state, task, or quality issue.
  • Translation updates: Let the agent revise translated content and update its review or status flags within a project or branch.
  • Localization key management: Direct your agent to search, create, update, or permanently delete localization keys, including their translations, metadata, review flags, and custom statuses.
  • Team activity auditing: Have your agent retrieve recent team audit events so you can inspect changes and localization activity.

Way Forward

With Lokalise connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

FAQ

Frequently asked questions

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

Yes, you can. Hermes 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 Lokalise tools.

Yes, absolutely. You can configure which Lokalise 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.

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 Lokalise data and credentials are handled as safely as possible.
