Many MCP projects begin with an existing API and a simple request: expose one backend capability to an LLM client. The quickest route is to wrap an endpoint as a tool and connect it to Claude or another MCP host. Users can then ask for data in natural language instead of navigating a fixed interface. This creates a production boundary because the model, rather than application code, chooses which operation to call. At Fullinfo, more than 1 million company profiles are served through a GraphQL backend on AWS AppSync. Users previously searched a portal and worked with the results using deterministic flows. With MCP, a user can ask, “Find SaaS companies in Germany with 50-200 employees,” and receive structured records in the conversation. The wrapper was straightforward in TypeScript and Go, but defining the model’s authority required more work. What Changes With MCP Governance? Existing API controls still apply, but they no longer cover the full decision path. A change to a tool name, description, or schema can affect which operation the model invokes. A generic GraphQL tool may expose too much capability, while a read-only tool may still perform a mutation. Prompt logs may also fail to show which tool was selected or which resources were accessed. Official MCP guidance covers confused deputy attacks, token passthrough, SSRF, and session hijacking. Backend teams must also manage risks created by their own tool definitions. Retrieved content can influence tool selection, while broad parameters can allow requests the product interface never supported. Governance, therefore, …
