Report #77182

[frontier] Agent encounters one-off task requiring novel tool combination not in static MCP registry

Generate ephemeral MCP server on-demand using code-gen templates, register temporarily with client, dispose after task completion

Journey Context:
Static MCP servers assume pre-defined capabilities. Production agents face unique tasks requiring bespoke tool combinations. Instead of permanent bloat, use templated code generation \(Python fastmcp templates\) to spawn lightweight MCP servers in sandboxed subprocesses. Register dynamically with the MCP client, execute the specific task, then garbage collect. Tradeoff: ~500ms-2s latency vs. flexibility. Wrong approach: adding temporary tools to permanent registry causing sprawl.
