Can I use Crossref as a CLI?

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

Can I expose Crossref through MCP?

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

Where are Crossref credentials stored?

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

Can I deny write access for Crossref MCP tools?

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

Crossref CLI for AI Agents

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

Crossref CLI Setup

Crossref can be configured headlessly with `kosmokrator integrations:configure crossref`.

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 crossref --enable --read allow --write ask --json
kosmokrator integrations:doctor crossref --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 crossref.crossref_list_works '{}' --json

Provider shortcut

kosmo integrations:crossref crossref_list_works '{}' --json

Discovery

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

Discovery commands

kosmo integrations:docs crossref --json
kosmo integrations:docs crossref.crossref_list_works --json
kosmo integrations:schema crossref.crossref_list_works --json
kosmo integrations:search "Crossref" --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.

Permissions

Headless calls still follow the integration read/write permission policy. Configure read/write defaults with integrations:configure. Add --force only for trusted automation that should bypass that policy.
