Can I use Hacker News as a CLI?

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

Can I expose Hacker News through MCP?

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

Where are Hacker News credentials stored?

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

Can I deny write access for Hacker News MCP tools?

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

Hacker News CLI for AI Agents

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

Hacker News CLI Setup

Hacker News can be configured headlessly with `kosmokrator integrations:configure hackernews`.

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 hackernews --enable --read allow --write ask --json
kosmokrator integrations:doctor hackernews --json
kosmokrator integrations:status --json

Credentials

Authentication type: No credentials none. Configure credentials once, then reuse the same stored profile from scripts, coding CLIs, Lua, and MCP.

No credentials are required.

Command Patterns

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

Generic CLI call

kosmo integrations:call hackernews.hackernews_get_item '{"id":1}' --json

Provider shortcut

kosmo integrations:hackernews hackernews_get_item '{"id":1}' --json

Discovery

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

Discovery commands

kosmo integrations:docs hackernews --json
kosmo integrations:docs hackernews.hackernews_get_item --json
kosmo integrations:schema hackernews.hackernews_get_item --json
kosmo integrations:search "Hacker News" --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.

CLI Functions

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