Tools & capabilities
Postlint MCP Server tools 3
check_postCheck a social post against one platform's real character limit and report whether it fits. Returns the counted length, the limit, and what drove the count (URLs billed at a fixed width, non-Latin characters billed double, emoji sequences collapsed to one grapheme). Use this before publishing anything with a hard limit — the counting rules are per-platform and are not text.length.check_post_allCheck one post against every platform at once and get a row per platform: counted length, limit, and whether it fits. Use this when deciding where a draft can go as-is. The per-platform arithmetic is included only for the platforms it fails, to keep the response small — call check_post for a single platform's full breakdown.platform_limitsList the platforms this server knows, with each one's limit, the unit it is measured in, why that unit is not a plain character count, and the source the number came from. Use it to explain a result or to see what is covered.
Synter Ads tools 56
list_campaignsList campaigns for ONE ad platform across all 16 ad platforms. `platform` is required -- this tool does not aggregate across platforms. Returns campaign name, status, budget, and performance metrics. 100% Free to Read ($0.00 / 0 credits — works out-of-the-box with zero configuration or API key; live write execution starts on the $20/month Solo plan).create_search_campaignCreate a Google Ads Search campaign with an ad group, responsive search ad, and keywords — all in one atomic request. Supports `dry_run: true` ($0.00 / 0 credits, zero credentials required) to preview payload and policy checks. Live execution passes the server-side Agent Shield safety gate (daily spend caps, paused-on-create default, human approval mode, and immutable workspace audit log) on the $20/month Solo plan ($20.00 included monthly credits, 0% ad-spend markup). IMPORTANT — creative floor: supply 11-15 headlines (15 recommended, max 30 chars each) and 4 descriptions (max 90 chars each), echoing your target keywords across at least 5 headlines. The API accepts as few as 3 headlines / 2 descriptions, but ads built near that minimum score 'Poor' on Google Ad Strength, get throttled in the auction, and may be rejected by the platform — treat 11 headlines / 4 descriptions as the real minimum. Fewer than 3 headlines or fewer than 2 descriptions will cause the campaign to be rejected before any API call is made.create_display_campaignCreate a Google Ads Display campaign with responsive display ads. Supports image uploads from URLs, `dry_run: true` ($0.00 / 0 credits, zero credentials required), and server-side safety gates (daily spend caps, paused-on-create default, approval mode, and audit log).create_pmax_campaignCreate a Google Ads Performance Max campaign. Requires images, headlines, descriptions, and a business name. Supports `dry_run: true` ($0.00 / 0 credits, zero credentials required) and server-side safety gates (daily spend caps, paused-on-create default, approval mode, and audit log).pause_campaignPause a campaign by ID across all 16 connected ad platforms. Supports `dry_run: true` ($0.00 / 0 credits, zero credentials required). Live execution is audited in the workspace audit log ($0.05 / 2 credits on Solo $20/mo plan).update_campaign_budgetUpdate the daily budget for a campaign across all 16 connected ad platforms. Supports `dry_run: true` ($0.00 / 0 credits, zero credentials required). Live execution passes the server-side Agent Shield safety gate (daily spend ceiling, max 2x budget-change multiplier, approval mode, and immutable audit log).get_performanceGet performance metrics (impressions, clicks, spend, conversions, ROAS) for campaigns across any of the 16 ad platforms. Free read-only tool ($0.00 / 0 credits).get_daily_spendGet daily spend breakdown for ONE ad platform across any of the 16 ad platforms. `platform` is required -- this tool does not aggregate across platforms. Free read-only tool ($0.00 / 0 credits).pacing_reportReturn a deterministic budget-pacing snapshot for the current workspace across every connected ad platform and the overall portfolio (month-to-date spend, today's spend, expected spend to date, pacing percent, projected end-of-period spend, on_track/underspending/overspending/critical status, and off-pace warnings). Free read-only tool ($0.00 / 0 credits).user_budget_pacing_reportReturn a deterministic per-user/trader budget ownership and pacing snapshot from saved workspace assignments (target budget, actual spend, expected spend, projected spend, variance, and pacing status). Free read-only tool ($0.00 / 0 credits).optimize_budgetRecommend a cross-channel budget allocation across connected ad platforms using diminishing-returns modeling.
