Can I use Splitwise as a CLI?

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

Can I expose Splitwise through MCP?

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

Where are Splitwise credentials stored?

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

Can I deny write access for Splitwise MCP tools?

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

Splitwise CLI for AI Agents

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

Splitwise CLI Setup

Splitwise can be configured headlessly with `kosmokrator integrations:configure splitwise`.

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 splitwise --set access_token="$SPLITWISE_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmokrator integrations:doctor splitwise --json
kosmokrator integrations:status --json

Credentials

Authentication type: Bearer token bearer_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`	`SPLITWISE_ACCESS_TOKEN`	Secret `secret`	yes	Access Token
`url`	`SPLITWISE_URL`	URL `url`	no	API URL

Command Patterns

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

Generic CLI call

kosmo integrations:call splitwise.splitwise_list_expenses '{"group_id":1,"friend_id":1,"dated_after":"example_dated_after","dated_before":"example_dated_before","limit":1,"offset":1}' --json

Provider shortcut

kosmo integrations:splitwise splitwise_list_expenses '{"group_id":1,"friend_id":1,"dated_after":"example_dated_after","dated_before":"example_dated_before","limit":1,"offset":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 splitwise --json
kosmo integrations:docs splitwise.splitwise_list_expenses --json
kosmo integrations:schema splitwise.splitwise_list_expenses --json
kosmo integrations:search "Splitwise" --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.

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.
