[frontier] Inconsistent tool schemas across MCP servers confuse agents and cause schema collisions

Deploy an MCP Gateway that normalizes tool schemas using JSON Schema transformations, enforces semantic versioning for tools, and filters exposed tools based on agent persona authorization.

Journey Context:
As teams adopt MCP servers from different vendors \(Stripe, Slack, internal\), agents face inconsistent naming \(get\_user vs fetchUser\) and breaking schema changes. Naive aggregation exposes hundreds of tools, causing confusion. The emerging pattern is an API Gateway for MCP: middleware that aggregates servers, normalizes naming via transformation rules, versions tools to prevent breaking changes, and filters tools based on agent authorization levels. This prevents agents from seeing tools they shouldn't use or being confused by similar-sounding tools.
