Tool access becomes a business decision.
MCP makes internal tools, workflows and external capabilities available through a common interface. As agents reach more systems, the business must determine which identity, delegated scope and policy apply to each action.
Frozion’s Tool Call Resolver/Router presents internal tools, workflows and connected external MCP endpoints to the LLM. Parameters can be populated over multiple model turns before invocation. Tool choice, input resolution and permission to execute remain separate decisions; external MCP calls receive policy checks before and after execution.
