Report #57335

[frontier] MCP servers siloed and unable to share tool outputs dynamically

Compose MCP servers by chaining tool outputs: use the result of one server's tool as input to another's within a single client session, treating MCP as a graph rather than a flat tool registry.

Journey Context:
Early MCP adoption treats each server as an isolated tool provider. Frontier production patterns instead wire multiple MCP servers \(e.g., 'GitHub Server' → 'Code Analysis Server' → 'Slack Server'\) into a directed graph. The client extracts the JSON result from Tool A and maps it to parameters of Tool B before invocation. This avoids the 'N×M integration problem' and replaces brittle custom scripts with declarative server composition. Alternative 'super-servers' that bundle everything violate separation of concerns and create maintenance monoliths.
