Implements deterministic execution for approved, trace-derived macros without introducing an additional permission model. - Replays captured MCP calls in order with input and prior-step bindings. - Adds schema drift validation, dry-run, cancellation, timeouts, audit logging, and bounded sanitized run records. - Adds source-aware MCP configuration discovery and connection reuse. - Exposes execution and run inspection through agent-server RPC and the macro MCP server. - Routes non-replayable calls to agent-guided execution. Validated with focused macro, replay-host, RPC, and plugin tests, plus the full workspace build.

This pull request adds comprehensive support for Copilot macro management to the agent server and protocol. It introduces new API methods for listing, searching, inspecting, creating, validating, approving, disabling, deleting, and running macros, as well as retrieving macro run information. The implementation is integrated across the protocol, client, server, and test layers, and updates the macro manager to use a replay host.
Macro Management API Additions:
Added new types and API methods for macro management to the protocol, including
listMacros,searchMacros,inspectMacro,getMacroRequirements,createMacroFromTrace,validateMacro,approveMacro,disableMacro,deleteMacro,runMacro,cancelMacroRun, andgetMacroRunin both the client and server implementations. [1] [2] [3]Updated the protocol exports to include all new macro-related types, ensuring they are available for use throughout the codebase. [1] [2]
Server and Macro Manager Integration:
MacroManagerwith aMcpReplayHost, enabling macro replay and inspection features. [1] [2]Testing Enhancements:
Stub and Adapter Updates:
Dependency Updates:
McpReplayHostand related types in server and test files to support replay functionality. [1] [2] [3]
