Integration · Synter

One MCP, 14 ad platforms.

Synter is the AI Agent Operator for Ads. A single hosted MCP server connects to 14 paid platforms with direct API connections and full execution.

Synter is the unification path for multi-platform paid media. Direct API connections (not middleware), 100+ tools across the surface, and full execution capabilities (not just reporting). Coverage includes Google, Meta, TikTok, LinkedIn, Reddit, Pinterest, Snapchat, Microsoft, X, Amazon DSP, Taboola, Spotify, Trade Desk, and StackAdapt. The strongest path when paid media spans more than three platforms and unified workflow matters.

Community MCP14 platforms in one connection. OAuth managed in the Synter dashboard.

What you can do via MCP

Example prompts the agent runs.

  • “Pull yesterday's spend across all 14 platforms grouped by channel.”

    Calls Synter's cross-platform reporting tool, aggregates spend per channel, and returns the rollup with per-platform breakdowns the agent can drill into.

  • “Find creative fatigue across Meta, TikTok, and Pinterest, anything with frequency above 3 or CTR drop above 30% week-over-week.”

    Queries insights across the named platforms via their respective Synter tools, joins by creative_id, surfaces the at-risk creatives with their pre-and-post fatigue performance.

  • “Sync my CRM customer list to lookalike audiences on Meta, Google, and LinkedIn.”

    Pushes the customer list to each platform via Synter's audience-sync tools, creates 1% lookalikes from the matched audiences, returns the audience IDs and estimated reach per platform.

  • “Create a search campaign in Google plus a video campaign in TikTok with the same audience targeting.”

    Creates both campaigns via Synter's per-platform create-campaign tools, applies the unified targeting via the audience-sync layer, returns campaign IDs and the cross-platform launch summary.

  • “Compare ROAS for the Q4 holiday campaign across Google PMax, Meta Advantage+, and TikTok Smart Performance.”

    Pulls campaign-level ROAS for the named campaigns across the three platforms, normalizes attribution windows, returns a side-by-side ROAS comparison with statistical caveats.

# Synter hosted MCP, called via the agent runtime
mcp.synter.get_cross_platform_spend({
  date_range: "yesterday",
  platforms: "all",  // or ["google", "meta", "tiktok", "linkedin"]
  group_by: "platform"
})

# Returns spend totals per platform plus a unified channel breakdown
# the agent can drill into for any specific platform.
One command sample showing how the agent talks to Synter. The MCP exposes the platform's primitives as tools; the agent translates the prompt into the right call.

Discrepancy auto-flagged when last-click and MMM differ by 15 percentage points or more.
Cross-platform attribution returned by Synter. TikTok's MMM share is 22% while last-click reads 8%; the agent flags the discrepancy and proposes shifting more budget to TikTok with an MMM-led measurement plan.

Six platforms, one dashboard. The agent normalized metrics across platforms; conversion definitions and attribution windows are unified at the Synter layer so the comparison is meaningful.

CLI alternative

Per-platform REST APIs, managed via the Synter dashboard.

Synter exposes per-platform REST API access through the dashboard for non-MCP workflows. For AI-driven multi-platform paid-media work the MCP is the primary interface; the dashboard fills in for OAuth handshakes, billing, and any platform-specific capability not yet exposed via MCP.
