audience_audit
Purpose
Audit existing Meta custom audiences, their usage, targeting fields, and auction overlap without claiming audience discovery.
Use when
- list or inspect custom audiences
- which ad sets use an audience
- lookalike or exclusion review
- audience overlap
Do not use
- interest, geography, or age/gender discovery
- live audience mutation without approval
- claims about audience size without tool evidence
Required inputs
- ad_account_id
Required evidence
- audience identity and subtype
- size and status when returned
- adsets using it
- targeting fields
- auction overlap evidence
- missing data
Output
Use the output contract audience_finding_v1. Keep facts, hypotheses, missing data, and the decision separate.
Hard rules
- Current MCP has no interest, geography, or age/gender discovery tool.
- Do not infer audience composition from names.
- Before a destructive audience change, collect usage and downstream impact.
- Audience creation remains a draft path.
