Can I use Reddit as a CLI?

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

Can I expose Reddit through MCP?

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

Where are Reddit credentials stored?

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

Can I deny write access for Reddit MCP tools?

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

Reddit CLI for AI Agents

Use the Reddit CLI from KosmoKrator to call Reddit tools headlessly, return JSON, inspect schemas, and automate workflows from coding agents, scripts, and CI.

Reddit CLI Setup

Reddit can be configured headlessly with `kosmokrator integrations:configure reddit`.

Install, configure, and verify

# 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 reddit --set access_token="$REDDIT_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmokrator integrations:doctor reddit --json
kosmokrator integrations:status --json

Credentials

Authentication type: Manual OAuth token oauth2_manual_token. Configure credentials once, then reuse the same stored profile from scripts, coding CLIs, Lua, and MCP.

Key	Env var	Type	Required	Label
`access_token`	`REDDIT_ACCESS_TOKEN`	Secret `secret`	yes	Access Token
`url`	`REDDIT_URL`	URL `url`	no	API Base URL

Command Patterns

The generic command is stable across every integration. The provider shortcut is shorter for humans.

Generic CLI call

kosmo integrations:call reddit.reddit_create_comment '{"parent":"example_parent","text":"example_text"}' --json

Provider shortcut

kosmo integrations:reddit reddit_create_comment '{"parent":"example_parent","text":"example_text"}' --json

Discovery

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

Discovery commands

kosmo integrations:docs reddit --json
kosmo integrations:docs reddit.reddit_create_comment --json
kosmo integrations:schema reddit.reddit_create_comment --json
kosmo integrations:search "Reddit" --json
kosmo integrations:list --json

Automation Contexts

The same configured command surface works in these environments. The command does not change unless the host wrapper, credentials, or permissions change.

CI Run integration calls from CI jobs with JSON output, explicit credentials, and predictable exit status. Cron Jobs Schedule repeatable integration workflows from cron while keeping credentials in KosmoKrator config. Shell Scripts Call integration functions from shell scripts with stable JSON input and output. Headless Automation Use KosmoKrator as a non-interactive integration runtime for local automations and wrappers. Coding Agents Let coding agents discover schemas and execute integration functions through CLI commands or MCP.

Every function below can be called headlessly. Commands are highlighted, copyable, and scroll horizontally when payloads are long.
