Meta Ads MCP

Get campaigns for a Meta Ads account with optional filtering.

Note: By default, the Meta API returns a subset of available fields. 
Other fields like 'effective_status', 'special_ad_categories', 
'lifetime_budget', 'spend_cap', 'budget_remaining', 'promoted_object', 
'source_campaign_id', etc., might be available but require specifying them
in the API call (currently not exposed by this tool's parameters).

Args:
    account_id: Meta Ads account ID (format: act_XXXXXXXXX)
    access_token: Meta API access token (optional - will use cached token if not provided)
    limit: Maximum number of campaigns to return (default: 10)
    status_filter: Filter by effective status (e.g., 'ACTIVE', 'PAUSED', 'ARCHIVED').
                   Maps to the 'effective_status' API parameter, which expects an array
                   (this function handles the required JSON formatting). Leave empty for all statuses.
    objective_filter: Filter by campaign objective(s). Can be a single objective string or a list of objectives.
                     Valid objectives: 'OUTCOME_AWARENESS', 'OUTCOME_TRAFFIC', 'OUTCOME_ENGAGEMENT',
                     'OUTCOME_LEADS', 'OUTCOME_SALES', 'OUTCOME_APP_PROMOTION'.
                     Examples: 'OUTCOME_LEADS' or ['OUTCOME_LEADS', 'OUTCOME_SALES'].
                     Leave empty for all objectives.
