MCP server for AI-powered translation management in i18n projects, enabling automated locale detection, translation status checks, and sync via LangAPI.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
get_account_statusGet the current LangAPI account status: plan (free/pro), the monthly word allowance and how much of it remains this period, the credit balance, and when the allowance resets. Use this to check remaining words/credits before syncing translations.
get_translation_statusCompare source locale against target locales to identify missing/outdated keys and estimate translation costs.
list_local_localesScan project for locale files (JSON, ARB, .strings, .xcstrings, .stringsdict), detect i18n framework (next-intl, i18next, react-intl, flutter, ios-macos, generic), and return structured information about available translations.
sync_translationsAdd new languages or sync existing translations via LangAPI. The server compares each file's current content against its previous translation and only translates what's new or changed. Default is dry_run=true for preview.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
When Vitest UI server is listening, arbitrary file can be read and executed
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
4/4 tools missing one or more hints — get_account_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_translation_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_local_locales (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 0/4 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
3/4 tools referenced in tests (75%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 call in production code run through a shell (src/auth/browser.ts:16)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.25.1 (high), @modelcontextprotocol/sdk@1.25.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @langapi doesn't match GitHub owner tedyhub
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
