Synter- Open source MCP server to manage ads across 7 platforms

Managing multiple ad platforms from your own server is a sensible, niche play for teams worried about vendor lock-in and auditability. The GitHub landing in the screenshot doesn't show the repo contents, so the value hinges on whether the project includes reliable connectors, auth flows (OAuth/token refresh), rate‑limit/backoff handling and unified reporting — without those, it reads like another integration skeleton rather than a drop‑in solution.
