Can I use DeepL as a CLI?

Yes. KosmoKrator exposes a DeepL CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose DeepL through MCP?

Yes. The KosmoKrator MCP gateway can expose selected DeepL tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are DeepL credentials stored?

DeepL credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for DeepL MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Connect DeepL to Vercel AI SDK

Use KosmoKrator as a local integration gateway for Vercel AI SDK agents and scripts.

Create an MCP client that starts or connects to the KosmoKrator gateway for the selected integration. The gateway is local, scoped to this integration, and starts with --write=deny so Vercel AI SDK can inspect read-capable tools without receiving write access by default.

DeepL MCP Config for Vercel AI SDK

Prefer CLI JSON calls when a workflow only needs one deterministic integration operation.

{
  "mcpServers": {
    "kosmokrator-deepl": {
      "type": "stdio",
      "command": "kosmo",
      "args": [
        "mcp:serve",
        "--integration=deepl",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

kosmokrator mcp:serve --integration=deepl --write=deny

Why Use KosmoKrator Here

Scoped tools

Expose only DeepL instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.

DeepL Tools Visible to Vercel AI SDK

MCP tool	Source function	Type	Description
`integration__deepl__deepl_translate_text`	`deepl.deepl_translate_text`	Write	Translate text using DeepL. Supports automatic source language detection or explicit source language specification. Returns translated text with detected source language.
`integration__deepl__deepl_list_languages`	`deepl.deepl_list_languages`	Read	List languages supported by DeepL. Returns language codes and names. Filter by type to get only source or target languages.
`integration__deepl__deepl_get_usage`	`deepl.deepl_get_usage`	Read	Get current DeepL API usage. Returns the number of characters translated and the character limit for the current billing period.
`integration__deepl__deepl_list_glossaries`	`deepl.deepl_list_glossaries`	Read	List all glossaries in your DeepL account. Returns glossary IDs, names, language pairs, and entry counts.
`integration__deepl__deepl_get_glossary`	`deepl.deepl_get_glossary`	Read	Get details of a specific DeepL glossary by ID. Returns glossary name, source/target languages, entry count, and creation timestamp.
`integration__deepl__deepl_create_glossary`	`deepl.deepl_create_glossary`	Write	Create a new DeepL glossary. Glossaries define custom translations for specific terms. Entries are tab-separated pairs (source\ttarget), one per line.
