Intlayer

name: Intlayer
description: Intlayer is an internationalisation (i18n) framework for modern web applications, providing one way to manage
  multilingual content across React, Next.js, Vue, Svelte, Solid, Nuxt and Astro. Beyond the open-source (Apache-2.0) framework
  it operates a hosted CMS API at back.intlayer.org secured with OAuth 2.0 client credentials, publishes an RFC 9727 API catalog,
  a machine-readable agent authentication guide (auth.md), and ships an official MCP server both hosted (mcp.intlayer.org)
  and as a stdio package (@intlayer/mcp), alongside extensive documentation written for agents as well as humans.

  description: Backend API for the hosted Intlayer CMS at back.intlayer.org — dictionaries, projects, organizations, environments
    and tags. Secured with OAuth 2.0 client_credentials (per-project access keys issued at app.intlayer.org); errors use a
    consistent JSON envelope. No OpenAPI is published — the surface is consumed through the first-party @intlayer/api SDK,
    the intlayer CLI, and the official MCP server, and documented for agents at intlayer.org/auth.md.

  note: 'Submitted via apis.io/add on 2026-08-26 and auto-published by the gate at rating 4 (minimal). Listed on the standing
    rule that a valid company with a real product gets a listing and the rating speaks for the rest. ORIGINAL FINDING (2026-08-26):
    apis[] was left empty because back.intlayer.org/apis.json, /.well-known/apis.json and /openapi.json all 404 and the llms.txt
    was read as mentioning no API. CORRECTED (2026-09-03 enrichment pass): Intlayer does have a real, reachable API surface
    the first pass missed. The llms.txt itself recommends the official MCP server (remote https://mcp.intlayer.org — anonymous
    tools/list returned 27 tools with schemas — and stdio npx -y @intlayer/mcp); intlayer.org serves a genuine RFC 9727 api-catalog
    linkset; back.intlayer.org serves RFC 8414 + RFC 9728 OAuth metadata whose agent_auth block points at a machine-readable
    agent auth guide (intlayer.org/auth.md) for the CMS API at back.intlayer.org/api/*. Still true: no OpenAPI/Swagger/GraphQL
    contract is published anywhere (probed again on all three hosts). A VulnerabilityDisclosure artifact briefly wired by
    the security-programs probe on 2026-09-03 was removed the same day: its evidence page (intlayer.org/vulnerability-disclosure)
    is the site''s SPA catch-all shell, not a disclosure page.'
