Melso MCP

Hosted MCP server for Melso, an AI tax and bookkeeping service for the self-employed and small companies in Spain. An AI client can read and record expenses, prepare invoice drafts, check the tax calendar and returns (such as modelo 303 and 130), and work with contacts, bank movements and documents for one authorized company. Approving, filing and paying taxes stay in the Melso app.

Most tools need a plan that includes them (Melso Pro is shown at EUR 490 billed yearly, EUR 40.83/mo); without one you can read your records and save case draftsDocs ↗
