Notsy FacturacióN
Emit Mexican CFDI 4.0 invoices and resolve SAT catalog keys from your AI agent when you run a Mexico-facing product or freelance billing.
Overview
Notsy Facturación MCP is an Operate-phase MCP server that lets AI agents emit CFDI 4.0 invoices and resolve SAT keys for Mexican businesses via Notsy’s permissioned API.
What is this MCP server?
- Streamable-HTTP MCP at mcp.notsy.com.mx with Bearer API key auth
- Emits CFDIs 4.0 compliant with Mexican tax requirements
- Resolves SAT claves and catalog lookups for agent-driven facturación
- API keys are scoped with permissions per business account
- Developer portal at facturacion.notsy.com.mx for key generation
- Server version 1.0.0
- 1 streamable-HTTP remote (mcp.notsy.com.mx/mcp)
- CFDI 4.0 emission and SAT key resolution per registry description
What problem does it solve?
Your agent can build the product but every Mexican invoice still forces you out of the IDE into the SAT-aligned billing UI and manual clave lookups.
Who is it for?
Mexico-based indie SaaS, ecommerce, or service founders who already use Notsy and want agent-driven CFDI issuance under API-key permissions.
Skip if: Builders outside Mexico, teams that only need US/EU payments, or anyone not ready to manage SAT CFDI compliance and Notsy account setup.
What do I get? / Deliverables
With a Notsy Bearer API key configured on the MCP remote, your agent can trigger permitted facturación and SAT resolution flows from the same session where you handle support and ops.
- Agent-callable CFDI 4.0 emission within API-key permissions
- SAT catalog/clave resolution through the Notsy MCP remote
- Documented v1.0.0 server wiring for ongoing operate-phase billing

Electronic invoicing and SAT compliance are ongoing production operations for Mexican builders, not one-off launch tasks—Operate is the canonical shelf. Iterate covers recurring billing, catalog key fixes, and permissioned API adjustments as your business rules evolve after ship.
How it compares
CFDI/SAT billing MCP integration, not a generic Stripe skill or local tax spreadsheet.
