-## HTTP / SSE Transport
+## HTTP Transports
 
-The `*server.SSEServer` returned by any of the helpers below implements `http.Handler`, so it works with every Go HTTP framework.
+`Config.BasePath` is required and used for all route registration.
+`Config.BaseURL` is optional — when empty it is detected from each request.
 
-### Gorilla Mux
+Two transports are supported: **SSE** (legacy, two-endpoint) and **Streamable HTTP** (recommended, single-endpoint).
+
+---
+
+### SSE Transport
+
+Two endpoints: `GET {BasePath}/sse` (subscribe) + `POST {BasePath}/message` (send).
+
+#### Gorilla Mux
 
 ```go
-resolvemcp.SetupMuxRoutes(r, handler, "http://localhost:8080")
+resolvemcp.SetupMuxRoutes(r, handler)
 ```
 
-Registers:
-
 | Route | Method | Description |
 |---|---|---|
-| `/mcp/sse` | GET | SSE connection — clients subscribe here |
-| `/mcp/message` | POST | JSON-RPC — clients send requests here |
-| `/mcp/*` | any | Full SSE server (convenience prefix) |
+| `{BasePath}/sse` | GET | SSE connection — clients subscribe here |
+| `{BasePath}/message` | POST | JSON-RPC — clients send requests here |
 
-### bunrouter
+#### bunrouter
 
 ```go
-resolvemcp.SetupBunRouterRoutes(router, handler, "http://localhost:8080", "/mcp")
+resolvemcp.SetupBunRouterRoutes(router, handler)
 ```
 
-Registers `GET /mcp/sse` and `POST /mcp/message` on the provided `*bunrouter.Router`.
-
-### Gin (or any `http.Handler`-compatible framework)
-
-Use `handler.SSEServer` to get a pre-bound `*server.SSEServer` and wrap it with the framework's adapter:
+#### Gin / net/http / Echo
 
 ```go
-sse := handler.SSEServer("http://localhost:8080", "/mcp")
+sse := handler.SSEServer()
 
-// Gin
-engine.Any("/mcp/*path", gin.WrapH(sse))
-
-// net/http
-http.Handle("/mcp/", http.StripPrefix("/mcp", sse))
-
-// Echo
-e.Any("/mcp/*", echo.WrapHandler(sse))
+engine.Any("/mcp/*path", gin.WrapH(sse))  // Gin
+http.Handle("/mcp/", sse)                  // net/http
+e.Any("/mcp/*", echo.WrapHandler(sse))     // Echo
 ```
 
+---
+
+### Streamable HTTP Transport
+
+Single endpoint at `{BasePath}`. Handles POST (client→server) and GET (server→client streaming). Preferred for new integrations.
+
+#### Gorilla Mux
+
+```go
+resolvemcp.SetupMuxStreamableHTTPRoutes(r, handler)
+```
+
+Mounts the handler at `{BasePath}` (all methods).
+
+#### bunrouter
+
+```go
+resolvemcp.SetupBunRouterStreamableHTTPRoutes(router, handler)
+```
+
+Registers GET, POST, DELETE on `{BasePath}`.
+
+#### Gin / net/http / Echo
+
+```go
+h := handler.StreamableHTTPServer()
+// or: h := resolvemcp.NewStreamableHTTPHandler(handler)
+
+engine.Any("/mcp", gin.WrapH(h))      // Gin
+http.Handle("/mcp", h)                 // net/http
+e.Any("/mcp", echo.WrapHandler(h))     // Echo
+```
+
+---
+
 ### Authentication
 
 Add middleware before the MCP routes. The handler itself has no auth layer.
 
 ---
 
+## Security
+
+`resolvemcp` integrates with the `security` package to provide per-entity access control, row-level security, and column-level security — the same system used by `resolvespec` and `restheadspec`.
+
+### Wiring security hooks
+
+```go
+import "github.com/bitechdev/ResolveSpec/pkg/security"
+
+securityList := security.NewSecurityList(mySecurityProvider)
+resolvemcp.RegisterSecurityHooks(handler, securityList)
+```
+
+Call `RegisterSecurityHooks` **once**, after creating the handler and before registering models. It installs these controls automatically:
+
+| Hook | Effect |
+|---|---|
+| `BeforeHandle` | Enforces per-entity operation rules (see below) |
+| `BeforeRead` | Loads RLS/CLS rules, then injects a user-scoped WHERE clause |
+| `AfterRead` | Masks/hides columns per column-security rules; writes audit log |
+| `BeforeUpdate` | Blocks update if `CanUpdate` is false |
+| `BeforeDelete` | Blocks delete if `CanDelete` is false |
+
+### Per-entity operation rules
+
+Use `RegisterModelWithRules` instead of `RegisterModel` to set access rules at registration time:
+
+```go
+import "github.com/bitechdev/ResolveSpec/pkg/modelregistry"
+
+// Read-only entity
+handler.RegisterModelWithRules("public", "audit_logs", &AuditLog{}, modelregistry.ModelRules{
+    CanRead:   true,
+    CanCreate: false,
+    CanUpdate: false,
+    CanDelete: false,
+})
+
+// Public read, authenticated write
+handler.RegisterModelWithRules("public", "products", &Product{}, modelregistry.ModelRules{
+    CanPublicRead: true,
+    CanRead:       true,
+    CanCreate:     true,
+    CanUpdate:     true,
+    CanDelete:     false,
+})
+```
+
+To update rules for an already-registered model:
+
+```go
+handler.SetModelRules("public", "users", modelregistry.ModelRules{
+    CanRead:   true,
+    CanCreate: true,
+    CanUpdate: true,
+    CanDelete: false,
+})
+```
+
+`RegisterModel` (no rules) registers with all-allowed defaults (`CanRead/Create/Update/Delete = true`).
+
+### ModelRules fields
+
+| Field | Default | Description |
+|---|---|---|
+| `CanPublicRead` | `false` | Allow unauthenticated reads |
+| `CanPublicCreate` | `false` | Allow unauthenticated creates |
+| `CanPublicUpdate` | `false` | Allow unauthenticated updates |
+| `CanPublicDelete` | `false` | Allow unauthenticated deletes |
+| `CanRead` | `true` | Allow authenticated reads |
+| `CanCreate` | `true` | Allow authenticated creates |
+| `CanUpdate` | `true` | Allow authenticated updates |
+| `CanDelete` | `true` | Allow authenticated deletes |
+| `SecurityDisabled` | `false` | Skip all security checks for this model |

+### Annotation Tool — `resolvespec_annotate`
+
+Store or retrieve freeform annotation records for any tool, model, or entity. Registered automatically on every handler.
+
+| Argument | Type | Description |
+|---|---|---|
+| `tool_name` | string (required) | Key to annotate — an MCP tool name (e.g. `read_public_users`), a model name (e.g. `public.users`), or any other identifier. |

 ### Resource — `{schema}.{entity}`
 
 Each model is also registered as an MCP resource with URI `schema.entity` (or just `entity` when schema is empty). Reading the resource returns up to 100 records as `application/json`.
