What you can do with Weblate in Claude and ChatGPT

For software teams who translate their projects in Weblate.

Check how complete each language is

The AI reads translation statistics for a project, a component or one language, with strings translated, needing edit and percentages.

Find strings that still need translating

The AI searches strings with Weblate's query syntax, for example by state, and shows source, target, context and failing checks.

Review suggestions and accept good ones

The AI lists suggested translations waiting for review, newest first, and applies the ones you choose to their strings.

Changes data

See who changed which translations

The AI reads the activity log for a project, component or language, with the user, action, time and changed text. It can filter by user or time range.

Translate a string, suggest a translation or comment

The AI sets the translation of one string, proposes a translation for review, or adds a comment to a string.

Changes data

Fill missing translations automatically

The AI runs automatic translation from other components or from machine translation. In suggest mode it only adds suggestions for review.

How do I connect Weblate?

Before you connect

The login page asks for your Weblate API token.

Optional: Instance address.

Create a token in Weblate: your profile (user menu) → Settings → API access; it starts with wlu_ (a project token, wlp_, limits the connection to one project). The token acts with your permissions, so a dedicated user makes its activity easy to track. The instance must be a public https:// address without a path. Your token is used only to call the Weblate API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Weblate and this URL, then click Add:
https://weblate.usefulapi.io/mcp
Claude opens the login page: enter your Weblate API token.
In a chat, click + → Connectors and turn on Weblate.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name Weblate and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://weblate.usefulapi.io/mcp
ChatGPT opens the login page: enter your Weblate API token.
In Plugins, install Weblate, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http weblate https://weblate.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "weblate": {
      "url": "https://weblate.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "weblate": {
      "type": "http",
      "url": "https://weblate.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add weblate --url https://weblate.usefulapi.io/mcp

codex mcp login weblate

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://weblate.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: the login page asks for your Weblate API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper API token	$9/mo · $90/yr	10,000 tool calls / month
Pro+per API token	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Weblate server only. Ask your AI to run weblate_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with weblate_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with weblate_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Changes data · 6

Update a translationweblate_update_translation
WRITE: set the translation of one string (replaces the current target). `target` is the list of plural forms. `state` is required (Weblate rejects a partial update without both): 0 untranslated with an empty target, 10 needs editing, 20 translated or 30 approved (approval needs the review workflow and permission). The number of plural forms must match the language. Changes are committed to the repository by Weblate's normal schedule.
Add a suggestionweblate_add_suggestion
WRITE: propose a translation for one string; normally a reviewer accepts it later, but the author's automatic upvote (or an existing identical suggestion) can reach the project's auto-accept threshold and apply it at once. Needs the Add suggestion permission and suggestions enabled (Weblate 2026.8+).
Accept a suggestionweblate_accept_suggestion
WRITE: apply a suggestion to its string (replaces the current translation). `approve` also marks it approved (review workflow and permission needed). Weblate 2026.8+.
Add a string commentweblate_add_unit_comment
WRITE: add a comment to one string (Markdown, @username mentions notify users). `scope` is global (all languages), translation (this language) or report (a source-string issue report; needs the review workflow). Weblate 5.12+.
Run a repository operationweblate_repository_operation
WRITE: commit (write pending translations into the local repository), pull (merge upstream changes) or push (publish committed changes to the remote repository) for a project or one component. Push changes the remote repository. reset and cleanup are not offered.
Run automatic translationweblate_autotranslate
WRITE: fill a translation automatically from other components (auto_source others, default) or from machine translation (mt, needs engines). `mode` suggest only adds suggestions (default), translate writes translations, fuzzy marks them needing edit. `q` limits it to strings matching a search (default state:<translated, the strings that are not translated yet); threshold is the minimum match score (default 80). Use background to schedule a task instead of waiting.

Your usefulapi plan · 4

Usage status (free-tier meter)weblate_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featureweblate_request_feature
Tell usefulapi that the user needs something the Weblate tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+weblate_upgrade
Get a paid plan for Weblate (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptionweblate_cancel_subscription
Cancel the caller's Weblate Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run weblate_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Weblate in Claude or ChatGPT?

Check how complete each language is. Find strings that still need translating. Review suggestions and accept good ones. See who changed which translations. Translate a string, suggest a translation or comment. Fill missing translations automatically. See what you can do for the details.

Is this an official Weblate product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Weblate. The server calls the Weblate API with your own Weblate access, so it sees only the data that your account can see.

Can I connect Weblate to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Weblate API token. See Before you connect for where to find it.

Do I put my Weblate key or an Authorization header in the client config?

No. 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: the login page asks for your Weblate API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Weblate credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Weblate API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Weblate.

Can the AI change my Weblate data?

Yes, if you approve it. 6 of the 23 Weblate tools can create or change data. The other 17 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Weblate server only. Cancel any time: your paid plan then runs to the end of the paid period. Run weblate_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run weblate_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run weblate_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Weblate tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with weblate_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
