RLC and per-worker RNT reports: docs and MCP tools

16/09/2026

Two TGSS report endpoints that already existed under /api/v4/seg-social had no page in this documentation. They do now:

• Contribution Settlement Receipt (RLC) — GET /report-rlc: the receipt of a contribution account code for a settlement type and a range of periods, as a PDF.
• Nominal List of Workers (RNT) for a worker — GET /report-rnt-for-nss: the RNT filtered by a worker's affiliation number, as a PDF.

Both pages list the full catalogue of liquidType values (L00, L02, L03, L13, L90…), the numAutorizado parameter for certificates with several RED authorised users and, for the RLC, the controlDate control date the RED System requires for L03 settlements.

The public MCP server (api.saltra.es/api/v4/mcp, version 1.0.3) adds the two mirror tools: tgss_report_rlc and tgss_report_rnt_for_nss, with the same field names as the pages.

Nothing changes in the REST API: these endpoints were already available.
