+### ResolveMCP (MCP Server)
+
+ResolveMCP exposes registered models as Model Context Protocol tools so AI models (Claude, Cursor, etc.) can query and mutate your database directly:
+
+```go
+import "github.com/bitechdev/ResolveSpec/pkg/resolvemcp"
+
+// Create handler
+handler := resolvemcp.NewHandlerWithGORM(db)
+
+// Register models — must be done BEFORE Build()
+handler.RegisterModel("public", "users", &User{})
+handler.RegisterModel("public", "posts", &Post{})
+
+// Finalize: registers MCP tools and resources
+handler.Build()
+
+// Mount SSE transport on your existing router
+router := mux.NewRouter()
+resolvemcp.SetupMuxRoutes(router, handler, "http://localhost:8080")
+
+// MCP clients connect to:
+//   SSE stream:  GET  http://localhost:8080/mcp/sse
+//   Messages:    POST http://localhost:8080/mcp/message
+//
+// Auto-registered tools per model:
+//   read_public_users   — filter, sort, paginate, preload
+//   create_public_users — insert a new record
+//   update_public_users — update a record by ID
+//   delete_public_users — delete a record by ID

+**Key Features**:
+- Four tools per model: `read_`, `create_`, `update_`, `delete_`
+- Rich AI-readable descriptions: column names, types, primary key, nullable flags, and preloadable relations
+- Full query support: filters, sort, limit/offset, cursor pagination, column selection, preloads
+- HTTP/SSE transport compatible with Claude Desktop, Cursor, and any MCP client
+- Same Before/After lifecycle hooks as ResolveSpec
