Trusted reads

Source context and safety travel with every result.

Your data stays unchanged

Tools read entitled data and, when enabled, construct custom lineup drafts. MCP cannot publish, change account data, place wagers, or enter contests.

Provenance travels with the answer

Historical results identify their immutable snapshot. Duck responses identify the actual run, source freshness, eligibility, warnings, and generation mode.

Observed and projected stay distinct

Historical NFL results are labeled as observed evidence. Duck salary, projection, value, and ownership fields remain clearly identified as published projections.

Access follows your account

MCP approval is account-specific. Premium and admin-only data remains entitlement-aware, and revoking access takes effect on the next request.
