# Moniary > Moniary is Czech accounting software for small companies and sole traders (OSVČ): received and issued invoices, AI document extraction, bank transactions and payment matching, VAT filings and income tax. Its public API and the `moniary` command line let scripts and AI agents do the same work as the app, as the key's user in one workspace. ## Ways to connect - **MCP server:** `https://moniary.com/api/mcp` (Streamable HTTP). Sign in with a Moniary account over OAuth and pick the workspaces to share; no API key needed. Best for chat clients and agents that speak MCP. Tools cover invoices, issued invoices, payments, bank transactions, contacts, tags and VAT previews; settings, deletes and sending payment orders stay in the app. - **API:** every action is called as `POST https://moniary.com/api/v1/actions/` with `Authorization: Bearer ` and a JSON body; the result is in `data`. Documents upload through `POST https://moniary.com/api/v1/uploads`. - **CLI:** `npx @moniary/cli login`, then `moniary actions`, `moniary run ` and `moniary upload `. Prefer read-only API keys, and ask the user before actions that issue, send or pay (API access `confirm`). ## Docs - [API](https://moniary.com/docs/api.md): Connect your own scripts, systems and AI agents to Moniary. - [CLI](https://moniary.com/docs/cli.md): Install the moniary command, sign in through your browser and work with Moniary from the terminal, scripts, CI and AI agents. - [API keys and sign-in](https://moniary.com/docs/api-klice.md): Create an API key, choose its access, sign in the CLI and revoke keys you no longer need. - [Actions](https://moniary.com/docs/api-akce.md): Find an action, read its input schema and run it.
