altalandi-mcp

An MCP server that exposes Altalandi — native-Icelandic refinement with a meaning-preservation check — as a tool any MCP client (Claude Code, etc.) can call. stdio transport.

Use it in Claude Code

Add to your MCP config (.mcp.json in the project, or your Claude Code config):

{
  "mcpServers": {
    "altalandi": {
      "command": "npx",
      "args": ["-y", "altalandi-mcp"],
      "env": { "ALTALANDI_API_KEY": "rtv_..." }
    }
  }
}

Mint a key at https://altalandi.is/portal. Then ask Claude to use the refine_icelandic tool.

The tool

refine_icelandic({ text, domain?, register?, sourceLang? }) → the native Icelandic text, a 0–100 nativeness score, and whether meaning was preserved.

• domain: general | marketing | data-analysis | childrens-fiction
• register: formal | neutral | warm
• sourceLang: auto | en | is

Meaning guarantee: on Icelandic input where the rewrite can't be verified to preserve meaning, the tool returns the original unchanged and flags it — never a silent change.
