Most marketing MCP servers are read-only because the alternative is frightening — an agent that can quietly change a budget. Splitting run_operation from run_write_operation makes the dangerous path explicit and puts an approval in front of it, which is what makes campaign creation and budget changes reasonable to enable at all. The meta-tool design is the other reason this works in practice: a thousand operations as a thousand tool definitions would not fit in a session, so the model searches for what it needs instead.
A hosted MCP server across a marketing stack — paid media, analytics, organic social, e-commerce, CRM and messaging — reached at one endpoint. It does not register a tool per platform operation. Eight meta-tools let the client search a registry of more than a thousand operations at runtime, so the catalogue can grow without the tool list growing with it.
- find_operations — search the registry by what you are trying to do, rather than by knowing the API
- get_operation_inputs — the input schema for the operation you picked
- run_operation and run_write_operation — reads and writes are separate tools, and the write path is where approval is enforced
- list_connections — which platform accounts are actually authenticated right now
- upload_media, read_file and get_file_url — get creative assets in, and get generated files back out
- Paid media across Google Ads, Meta Ads, TikTok, LinkedIn, Microsoft, Reddit, Pinterest, Snapchat, Amazon and DV360; analytics through GA4, BigQuery, Search Console and Merchant Center; organic social, Shopify, HubSpot, Klaviyo, WhatsApp and Slack
