SimpleLocalize MCP with Claude: Faster Multilingual App Releases
The short answer
Claude works with SimpleLocalize through the Model Context Protocol (MCP), a secure standard that lets Claude read and act inside the tool with permissions you set. Once connected, Claude can list languages, find localization keys, update translations and handle imports and exports from plain English requests, with your team approving important changes.
What is SimpleLocalize?
SimpleLocalize is a translation management platform. It stores localization keys, the translated text for each key, and the list of languages a project uses. Product teams, localization managers and developers use it to keep web and mobile apps consistent across markets. It also supports importing translation files and exporting them for use in builds and hosted environments, so teams can ship multilingual releases with less manual handling.
How Claude connects to SimpleLocalize through MCP
The Model Context Protocol (MCP) is an open standard that lets Claude securely use other software. Think of it as a universal adapter between Claude and a tool. It lets Claude read information and take actions, with access the organisation decides on in advance. SimpleLocalize offers an MCP server and a direct API, so Claude can reach your project through a supported route.
Once connected, Claude can typically list the languages in a project, search for localization keys, review existing translations, update specific entries and prepare file imports or exports. A product manager could ask in plain English for every key tagged as checkout to be reviewed for a new French wording, and Claude carries out the lookup and proposed edits.
Permissions and approvals keep people in charge. Access uses an API key with least-privilege settings, so Claude only touches what it is allowed to touch. We typically set approval steps for bulk changes, imports that overwrite live text and anything that affects a published language, and every action is logged so teams can review what happened.
What you can automate
Translating new interface text
When developers add new screens or buttons, Claude can identify the new localization keys and check which languages still lack translations. It can then prepare drafts for the translation team to review. This reduces the gap between a feature being built and it being ready for every market, which is especially helpful for teams releasing often.
Finding and fixing inconsistent wording
Localization managers often find that the same term is translated three different ways across a product. Claude can search keys by phrase or tag, group the variations and propose one consistent term. A reviewer approves the changes before they go live, keeping brand language steady across the app.
Preparing language rollouts
Before launching in a new market, a team needs to confirm the new language exists in the project, that its files are imported correctly and that coverage is high enough to publish. Claude can list the language, report missing translations by area and prepare the import, giving the launch lead a clear status update.
Keeping exports ready for release
Engineering teams need the latest translation files before each build. Claude can request an export for the chosen languages and check it against the expected key count, flagging any gaps. This helps catch missing text before it reaches users, rather than after a release has gone out.
Answering translation questions from support
Support staff often ask where a piece of on-screen text comes from and how it reads in another language. Claude can look up the matching key and its translations, then summarise them in plain language. This shortens investigation time and reduces the need to involve developers for simple wording questions.
An end-to-end workflow: Weekly release localization check
TriggerEvery Thursday afternoon, before the Friday release, or when a developer marks a feature ready for translation.
Claude lists all languages in the SimpleLocalize project and counts untranslated keys for each.
It identifies keys added or changed since the last release, using the project's recent activity.
Claude drafts translations for the gaps and flags any terms that conflict with the approved glossary.
The localization manager reviews and approves the drafts inside the approval step before anything is published.
Claude prepares the export for approved languages and posts a short summary to the release channel in Microsoft Teams, which the team already uses.
Claude records the export and changes in the audit log for the release record.
OutcomeReleases reach users with complete translations in every supported language, and the localization team spends less time chasing gaps. Results vary by project size and review process.
How we set it up
Free automation audit
We review how your team currently manages translations, releases and approvals, and identify the workflows worth automating with Claude and SimpleLocalize.
Secure API key connection
We set up access using a SimpleLocalize API key, scoped to the minimum permissions the workflow needs, and connect Claude through the MCP server or direct API.
Workflow design
We design the end-to-end process across SimpleLocalize and your other systems, such as Microsoft 365, your ticketing tool or your build pipeline, with clear approval points for consequential changes.
Testing on real cases
We test the workflow against past releases and real translation files, checking accuracy, approval routing and export completeness before anything goes live.
Launch, monitoring and training
We launch with audit logs and monitoring in place, then train your localization, product and engineering staff on how to use Claude safely and review its work.
Who benefits
- Localization manager
- Spots gaps and inconsistent terms quickly and keeps glossary decisions in one approval flow.
- Software developer
- Gets translation keys and exports handled without breaking focus on feature work.
- Product manager
- Checks language coverage before launch dates and avoids last-minute surprises.
- Support lead
- Answers wording questions from support tickets without waiting on engineering.
Security and control
- Least-privilege API key access, limited to the projects and actions each workflow needs.
- Human approval for bulk edits, overwrites of live text and changes to published languages.
- Full audit logs of every action Claude takes in SimpleLocalize, reviewable at any time.
- Regular review of permissions and API keys, with rotation when team members change roles.
- Clear rules on which content Claude may draft and which must always be written or signed off by a person.
For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can host the Claude workflow in their chosen region to meet internal data policies. Teams in India must consider the Digital Personal Data Protection Act, 2023, when translation content includes personal data, and we design access accordingly. Businesses in the Middle East, including the UAE and Saudi Arabia, must follow local data protection laws, and we select a hosting region to match those requirements. Hosting location is chosen during design to meet each client's obligations.

Frequently asked questions
What does the SimpleLocalize MCP server do?
The SimpleLocalize MCP server is a secure bridge that lets AI tools such as Claude work with your project. Through it, Claude can typically list languages, find localization keys, update translations, and handle file imports and exports, all from natural language requests. It acts only within the permissions you grant.
Is it secure to connect SimpleLocalize to Claude?
Security depends on how access is set up. Connections use an API key, which we scope to the least access each workflow needs. Important actions can require human approval, and every action is logged. We also review keys regularly and rotate them when staff change roles.
What can Claude actually do in SimpleLocalize?
Typically, Claude can list languages, search localization keys, review and update translations, and prepare imports or exports. It can also answer questions about where text appears and how it reads in other languages. Claude works within the permissions set for the connection and cannot exceed them.
How long does setup take?
Timing depends on the size of your project and how many workflows you want to automate. A focused single workflow is often connected and tested within a few weeks, while broader programmes take longer. Your free automation audit gives you a realistic timeline before any work begins.
Which plan or permissions do I need?
You need a SimpleLocalize account with an API key that has permission for the projects and actions you want Claude to use. The exact plan requirements depend on what your workflow needs, so we confirm access during the audit and set the key to the least permissions required.
