Can I use Mastodon as a CLI?

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

Can I expose Mastodon through MCP?

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

Where are Mastodon credentials stored?

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

Can I deny write access for Mastodon MCP tools?

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

Mastodon MCP Gateway

Expose Mastodon to MCP clients with `kosmokrator mcp:serve --integration=mastodon`.

If the client has never used KosmoKrator before, install it first, then register this integration as a stdio MCP server. The gateway exposes only the selected integration in the example below.

curl -fsSL https://raw.githubusercontent.com/OpenCompanyApp/kosmokrator/main/install.sh | bash

kosmokrator mcp:gateway:install --integration=mastodon --write=deny --json

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