 Status: completed
 
 DoD:
 
-- `mcp-server` exposes a single MCP HTTP endpoint
-- initialize and initialized lifecycle work with session handling
-- tools are listed and called through MCP JSON-RPC methods
-- published tool catalog refreshes without service restart
-- MCP integration tests cover initialize, list, call and refresh flow
+- GraphQL operation can be created, tested and published
+- variables mapping and `response_path` work in runtime
+- GraphQL `errors` are translated into runtime failures
+- published GraphQL tool is callable through MCP
+- integration tests cover admin-api, runtime and MCP GraphQL scenarios
