Every SaaS company is building its own agent integration and we're all going to pay for it

Been watching the MCP land rush and it's getting silly. Blockworks shipped a hosted server for their datasets, Notolens for brand protection, Genea for access control. One insurer launched a whole directory where every carrier lists its own server. Silverchair just ran a six-month pilot of a single shared endpoint across independent publishers instead of per-publisher integrations — honestly that's the direction that makes sense. Stacklok's 2026 report says 45% of software orgs already run MCP servers. The instinct is right. Agents need structured doors, not scraped pages. But here's what's been bugging me: every door is a separate integration to build, secure, version, and maintain. Every API change is an agent breakage waiting to happen. Every new tool in the stack starts the work again from zero. The industry is rebuilding the same connector dozens of times and calling it strategy. One integration per app scales linearly. One infrastructure layer scales once. If every tool you buy ships its own agent interface next year, who maintains the fifty doors in your stack?
