  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Common questions

### What is the Hacienda Costa Rica MCP server?

Hacienda Costa Rica is an MCP server listed in the public MCP registry as io.github.jmnzcn/mcp-hacienda-cr. Hacienda de Costa Rica: tipo de cambio, contribuyentes, códigos CABYS con IVA y exoneraciones. This page covers its npm package (mcp-hacienda-cr).

### Is the Hacienda Costa Rica MCP server safe to use?

Hacienda Costa Rica scores 65 out of 100 on VerifyMCP. We recorded 1 known advisory against it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Hacienda Costa Rica MCP server expose?

Hacienda Costa Rica exposes 5 tools: tipo_de_cambio, consultar_contribuyente, buscar_cabys, obtener_cabys, consultar_exoneracion. Their descriptions and schemas cost roughly 364 tokens of context every time the server is loaded.

### Is the Hacienda Costa Rica MCP server still maintained?

Hacienda Costa Rica is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Hacienda Costa Rica MCP server under?

Hacienda Costa Rica declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Hacienda Costa Rica MCP server?

VerifyMCP ran 15 checks on Hacienda Costa Rica, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Hacienda Costa Rica: Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
