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 CLI Setup

Mastodon can be configured headlessly with `kosmokrator integrations:configure mastodon`.

# Install KosmoKrator first if it is not available on PATH.
curl -fsSL https://raw.githubusercontent.com/OpenCompanyApp/kosmokrator/main/install.sh | bash

# Configure and verify this integration.
kosmokrator integrations:configure mastodon --set access_token="$MASTODON_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmokrator integrations:doctor mastodon --json
kosmokrator integrations:status --json

Credentials

Authentication type: Bearer token bearer_token. Configure credentials once, then use the same stored profile from scripts, coding CLIs, Lua code mode, and the MCP gateway.

Key	Env var	Type	Required	Label
`access_token`	`MASTODON_ACCESS_TOKEN`	Secret `secret`	yes	Access Token
`instance_url`	`MASTODON_INSTANCE_URL`	URL `url`	no	Instance URL

Call Mastodon Headlessly

Use the generic call form when another coding CLI or script needs a stable universal interface.

kosmo integrations:call mastodon.mastodon_list_statuses '{
  "timeline": "example_timeline",
  "limit": 1,
  "max_id": "example_max_id",
  "since_id": "example_since_id"
}' --json

Use the provider shortcut form for shorter human-facing commands.

kosmo integrations:mastodon mastodon_list_statuses '{
  "timeline": "example_timeline",
  "limit": 1,
  "max_id": "example_max_id",
  "since_id": "example_since_id"
}' --json

Agent Discovery Commands

These commands return structured output for coding agents that need to inspect capabilities before choosing a function.

kosmo integrations:docs mastodon --json
kosmo integrations:docs mastodon.mastodon_list_statuses --json
kosmo integrations:schema mastodon.mastodon_list_statuses --json
kosmo integrations:search "Mastodon" --json
kosmo integrations:list --json

All CLI Functions

Every function below can be called headlessly. The generic form is stable across all integrations; the provider shortcut is shorter but specific to Mastodon.
