MCP changelog

The MCP schema version identifies the public tool catalog. Stenz may improve compatible descriptions and implementation details without creating a new version; tool, scope, risk, or contract changes are recorded here.

2026-07-20

Section titled “2026-07-20”
  • Published schema 2026-07-20 with 70 tools across 12 capability clusters.
  • Added scoped Flash catalogue and reservation reads plus confirmed publication, pricing, status, and reservation transitions.
  • Kept booking cancellation and payment refunds on their existing R3 approval paths; Flash reads omit storage/provider identifiers and mask client/payment data without the matching scopes.

2026-07-13

Section titled “2026-07-13”
  • Published schema 2026-07-13 with 61 tools across 10 studio capability clusters.
  • Added four explicit risk levels, per-tool OAuth scopes, read-only/destructive/open-world hints, confirmations, and in-app approvals.
  • Defined a full custom-connector catalog and a 60-tool Claude directory catalog that excludes deposit_refund.
  • Kept account credentials, artist deletion, input schemas, tokens, tenant policies, and internal function names outside the public catalog.

After a schema update, ChatGPT or Claude may still show a cached tool snapshot. Rescan tools or recreate the draft connector, then review any newly requested scope before accepting.
