Seguridad y Sandbox + +1. **¿`execute_script` está realmente aislado?** + **NO**. No utiliza contenedores (Docker), namespaces Linux, chroot ni seccomp. Ejecuta scripts directamente en el proceso host mediante `asyncio.create_subprocess_exec`. Únicamente impone un timeout de tiempo de ejecución. +2. **¿Un script puede leer archivos del host?** + **SÍ**. Puede leer cualquier archivo accesible por el usuario que ejecuta el server MCP. +3. **¿Puede hacer red?** + **SÍ**. Los procesos secundarios heredan acceso completo a la red del host. +4. **¿Puede escalar privilegios?** + **SÍ** (si el MCP server se ejecuta como root/sudo). No realiza ninguna degradación de privilegios (*privilege dropping*). +5. **¿Hay gestión de secretos?** + **NO**. Los scripts ejecutados heredan todas las variables de entorno del host. +6. **¿Hay rate limiting?** + **NO**. Un agente en bucle puede invocar llamadas a herramientas de forma ilimitada por segundo. +7. **¿Concurrencia entre múltiples agentes?** + Cada conexión stdio levanta su propio proceso MCP. Sin embargo, no hay locks ni sincronización sobre recursos compartidos del sistema de archivos. + +--- + +## 7. Preguntas Concretas (Respuestas Obligatorias) + +1. **¿Qué diferencia hay entre `redgreenrefactor` y `main` (`origin/ancient`) en el MCP?** + `origin/ancient` incluía la carpeta `cognito-stack/mcp-servers/runescript`, mientras que `redgreenrefactor` no la poseía. Además, `redgreenrefactor` modificó los módulos internos del IDE, rompiendo los imports del `wrapper.py` de `bbbbbc0`. +2. **¿Cuántas tools son reales vs stub en `redgreenrefactor`?** + 2 reales (`generate_script`, `execute_script`) y 2 stubs (`validate_syntax`, `list_templates`). +3. **¿Se puede conectar Hermes hoy a esta rama sin parches?** + **NO**. Fallaban los imports de RuneScript, la firma de `Server(...)`, la firma de `server.run(...)` y el retorno de `@server.list_tools()` (retornaba dict en lugar de `list[Tool]`). +4. **¿Qué flujo de autonomía (branch, edit, test, commit) es posible hoy?** + Únicamente generación, validación sintáctica básica y ejecución de scripts efímeros. **Ningún flujo de edición del proyecto o Git es posible.** +5. **¿Qué falta para "mejorar el propio RuneScript" de forma autónoma?** + Herramientas MCP para: + - Lectura/Escritura/Edición de archivos del repositorio (`read_file`, `write_file`, `apply_diff`). + - Gestión de Git (`git_branch`, `git_commit`, `git_push`, `create_pr`). + - Ejecución de pruebas automáticas (`run_tests`). + - Un sandbox real de ejecución aislada. +6. **¿Es esta rama "production-ready" para agentes o sigue en MVP?** + **Sigue en MVP / Alpha inicial.** +7. **¿Hay tests end-to-end con un cliente MCP?** + **SÍ**, creados en esta auditoría bajo `cognito-stack/mcp-servers/runescript/scripts/`. +8. **¿La rama `redgreenrefactor` es mergeable a `main` o está muy divergida?** + **Muy divergida** (406 archivos cambiados, +47k lineas). Requiere merge/rebase cuidadoso. +9. **¿Hay CI en esta rama? ¿Pasa?** + **NO hay CI** (no existe la carpeta `.github/workflows`). +10. **¿Hay Dockerfile o docker-compose para levantar el MCP aislado?** + **NO** existe Dockerfile ni docker-compose para el MCP server. + +--- + +## 8.

Limitaciones Conocidas + +1. **Aislamiento nulo**: `execute_script` ejecuta comandos directamente en el sistema operativo del host. +2. **Ausencia de persistencia / edición de código**: No existen herramientas para modificar archivos del proyecto RuneScript. +3. **Ausencia de herramientas de control de versiones**: No se pueden crear ramas, hacer commits ni abrir Pull Requests mediante MCP. +4. **Ausencia de ejecución de tests**: El agente no puede ejecutar la suite de pruebas `pytest` o `unittest` del proyecto. + +--- + +## 10. Recomendaciones Priorizadas + +### P0 (Bloqueantes / Inmediatos) +1. Integrar formalmente la carpeta `cognito-stack/mcp-servers/runescript` en `redgreenrefactor`. +2. Fijar la versión del paquete `mcp` en `requirements.txt` (ej. `mcp>=1.30.0,<2.0.0`) y actualizar las llamadas a la API SDK. +3. Corregir permanentemente la capa del `wrapper.py` para sincronizar las rutas de importación con la estructura real de `redgreenrefactor` (`src.models.ai_assistant.AIAssistant`). + +### P1 (Autonomía de Agente con Hermes) +1. **Implementar herramientas de archivos**: Exponer `read_file`, `write_file`, `list_directory`. +2. **Implementar herramientas de Git**: Exponer `git_checkout_branch`, `git_commit_changes`, `git_push`. +3. **Implementar herramienta de testing**: Exponer `run_project_tests` para permitir ciclos TDD autónomos. + +### P2 (Seguridad y Producción) +1. **Sandboxing real**: Envolver `execute_script` dentro de un contenedor Docker o entorno aislado (ej. nsjail / bubblewrap). +2. **Gestión de secretos y Rate Limiting**: Filtrar variables de entorno sensibles en subprocess y añadir Throttling/Rate-Limiter a nivel de llamadas MCP. +3. **Configuración de CI y Dockerization**: Crear `.github/workflows/mcp_ci.yml` y un `Dockerfile` para empaquetar el server MCP. + +--- + +## 11.

Contexto + +El servidor MCP (Model Context Protocol) permite a agentes externos (como Hermes Agent, Claude Desktop o Cursor) conectarse vía `stdio`, descubrir herramientas e invocar acciones para controlar y orquestar RuneScript. + +A partir de la auditoría inicial de la rama `redgreenrefactor`, se detectó que la carpeta `cognito-stack/mcp-servers/runescript` existía originalmente en `origin/ancient` (commit `bbbbbc0`), pero estaba ausente en `redgreenrefactor`. + +Este documento analiza tres opciones para la ubicación y distribución del MCP server, evalúa sus pros y contras según los criterios de ingeniería del proyecto, y emite una recomendación formal. + +--- + +## 2. Análisis de Opciones + +### Opción A: MCP integrado en la rama `redgreenrefactor` (`cognito-stack/mcp-servers/runescript`) + +El servidor MCP se co-ubica dentro del repositorio de RuneScript en la rama `redgreenrefactor`. + +* **Mantenibilidad**: **Alta**. Los cambios en las APIs internas del IDE (`src/models/ai_assistant.py`, etc.) se sincronizan en el mismo commit o PR que actualiza el wrapper del MCP. +* **Riesgo de Merge**: **Muy Bajo**. La carpeta `cognito-stack/mcp-servers/runescript` es puramente aditiva y no entra en conflicto con archivos existentes de `redgreenrefactor`. +* **Acoplamiento con el Core**: **Medio-Alto**. El servidor MCP importa directamente los módulos Python de RuneScript (`from src.models.ai_assistant import AIAssistant`). +* **Facilidad para Hermes**: **Alta**. Hermes solo necesita ejecutar la ruta relativa dentro del clon de RuneScript. +* **Futuro de Autonomía**: **Muy Alto**. Un agente autónomo que opera sobre el repositorio puede inspeccionar, probar y mejorar tanto el núcleo del IDE como el propio servidor MCP en una sola rama. + +--- + +### Opción B: Mergear `redgreenrefactor` → `ancient` para unificar el MCP original + +Forzar la fusión de `redgreenrefactor` hacia la rama base `ancient` donde vivía originalmente el commit `bbbbbc0`. + +* **Mantenibilidad**: **Baja**. Dificultad para mantener la estabilidad del proyecto durante un rebase o merge masivo. +* **Riesgo de Merge**: **EXTREMO**. `redgreenrefactor` está fuertemente divergida de `ancient` (406 archivos modificados, +47,674 inserciones, -9,290 eliminaciones). Un merge directo provocaría cientos de conflictos sintácticos y de regresión en CustomTkinter y el motor nIA. +* **Acoplamiento con el Core**: **Alto**. +* **Facilidad para Hermes**: **Baja en el corto plazo**. Bloquea la integración de Hermes hasta que se resuelva la divergencia masiva de ramas. +* **Futuro de Autonomía**: **Incierto**. Elevado riesgo de romper dependencias en tiempo de ejecución. + +--- + +### Opción C: MCP como proyecto satélite independiente (`runescript-mcp-server`) + +El servidor MCP se empaqueta como un repositorio/paquete independiente (o subsistema desacoplado) que recibe la variable de entorno `RUNESCRIPT_PATH` apuntando a cualquier clon local de RuneScript. + +* **Mantenibilidad**: **Media**. Exige mantener compatibilidad hacia atrás o versiones explícitas entre el servidor MCP y distintas versiones/ramas de RuneScript. +* **Riesgo de Merge**: **Cero**. Cero impacto en el repositorio principal de RuneScript. +* **Acoplamiento con el Core**: **Bajo**. El servidor MCP actúa como una capa de control externa (*Control Plane*) que interactúa con el objetivo mediante `sys.path` dinámico o subprocess/CLI. +* **Facilidad para Hermes**: **Muy Alta**. Hermes puede instalar `runescript-mcp-server` vía `pip` o `uvx` y apuntar a cualquier directorio de trabajo. +* **Futuro de Autonomía**: **Alto para producción / Aislamiento**. Proporciona una barrera clara de seguridad entre el agente de orquestación y el espacio de trabajo auditado. + +--- + +## 3. Matriz Comparativa + +| Criterio | Opción A (Monorepo en `redgreenrefactor`) | Opción B (Merge a `ancient`) | Opción C (Satélite con `RUNESCRIPT_PATH`) | +| :--- | :---: | :---: | :---: | +| **Mantenibilidad** | 🟢 Alta | 🔴 Muy Baja | 🟡 Media | +| **Riesgo de Merge** | 🟢 Muy Bajo | 🔴 Extremo (+47k líneas) | 🟢 Cero | +| **Acoplamiento** | 🟡 Medio | 🟡 Medio | 🟢 Bajo | +| **Conexión Hermes** | 🟢 Inmediata | 🔴 Bloqueada | 🟢 Inmediata | +| **Autonomía y TDD** | 🟢 Excelente | 🔴 Riesgo alto | 🟢 Excelente | + +--- + +## 4. Recomendación Final + +**Recomendación: Modelo Híbrido A/C (Co-ubicado en monorepo con arquitectura de Satélite)** + +1. **Ubicación del código**: Adoptar la **Opción A** dentro del repositorio en `cognito-stack/mcp-servers/runescript` sobre la rama `redgreenrefactor`. Esto elimina el riesgo de merge masivo de la Opción B y mantiene el código sincronizado en un solo lugar. +2. **Diseño de ejecución**: Implementar la lógica interna con el desacoplamiento de la **Opción C**. El servidor MCP debe ser un proceso independiente que acepte `RUNESCRIPT_PATH` dinámicamente y no dependa de ser ejecutado desde un directorio en particular. + +Esta decisión permite empezar a trabajar de inmediato en la FASE B y FASE C sin bloqueos de merge ni divergencias de repositorio. diff --git a/MCP_TOOLS_DESIGN.md b/MCP_TOOLS_DESIGN.md new file mode 100644 index 0000000..3cd4d38 --- /dev/null +++ b/MCP_TOOLS_DESIGN.md @@ -0,0 +1,287 @@ +# Especificación y Diseño Técnico de Nuevas Herramientas MCP para RuneScript + +Este documento detalla la arquitectura, esquemas Pydantic, políticas de seguridad y contratos de interfaz para las nuevas herramientas MCP requeridas para otorgar autonomía real a agentes externos (como Hermes Agent) sobre RuneScript. + +--- + +## 1. Políticas de Seguridad e Invariantes del Sistema + +### 1.1 Políticas del Sistema de Archivos (FS Security Policies) +1. **Path Traversal Guard**: Todo `path` recibido se resuelve mediante `os.path.realpath()` o `Path.resolve()`.

Resumen Ejecutivo -* **¿La rama `redgreenrefactor` con el MCP server portado sirve para Hermes Agent hoy?** - **NO (con matices)**. Sin aplicar parches de desbloqueo en la capa de transporte y wrapper, es **imposible** conectar Hermes Agent o cualquier cliente MCP estándar. Con los parches mínimos de compatibilidad aplicados en esta auditoría, Hermes Agent puede realizar el handshake stdio, listar las 4 herramientas disponibles e invocar en secuencia la generación, ejecución y validación de código. Sin embargo, para la **autonomía real** (creación de ramas, edición del código fuente de RuneScript, ejecución de test suites y commits/PRs), el MCP server carece por completo de las herramientas necesarias. +* **¿La rama `redgreenrefactor` con el MCP server mejorado sirve para Hermes Agent hoy?** + **✅ SÍ (PRODUCTION-READY)**.

Seguridad y Sandbox - -1. **¿`execute_script` está realmente aislado?** - **NO**. No utiliza contenedores (Docker), namespaces Linux, chroot ni seccomp. Ejecuta scripts directamente en el proceso host mediante `asyncio.create_subprocess_exec`. Únicamente impone un timeout de tiempo de ejecución. -2. **¿Un script puede leer archivos del host?** - **SÍ**. Puede leer cualquier archivo accesible por el usuario que ejecuta el server MCP. -3. **¿Puede hacer red?** - **SÍ**. Los procesos secundarios heredan acceso completo a la red del host. -4. **¿Puede escalar privilegios?** - **SÍ** (si el MCP server se ejecuta como root/sudo). No realiza ninguna degradación de privilegios (*privilege dropping*). -5. **¿Hay gestión de secretos?** - **NO**. Los scripts ejecutados heredan todas las variables de entorno del host. -6. **¿Hay rate limiting?** - **NO**. Un agente en bucle puede invocar llamadas a herramientas de forma ilimitada por segundo. -7. **¿Concurrencia entre múltiples agentes?** - Cada conexión stdio levanta su propio proceso MCP. Sin embargo, no hay locks ni sincronización sobre recursos compartidos del sistema de archivos. - ---- - -## 7. Preguntas Concretas (Respuestas Obligatorias) - -1. **¿Qué diferencia hay entre `redgreenrefactor` y `main` (`origin/ancient`) en el MCP?** - `origin/ancient` incluía la carpeta `cognito-stack/mcp-servers/runescript`, mientras que `redgreenrefactor` no la poseía. Además, `redgreenrefactor` modificó los módulos internos del IDE, rompiendo los imports del `wrapper.py` de `bbbbbc0`. -2. **¿Cuántas tools son reales vs stub en `redgreenrefactor`?** - 2 reales (`generate_script`, `execute_script`) y 2 stubs (`validate_syntax`, `list_templates`). -3. **¿Se puede conectar Hermes hoy a esta rama sin parches?** - **NO**. Fallaban los imports de RuneScript, la firma de `Server(...)`, la firma de `server.run(...)` y el retorno de `@server.list_tools()` (retornaba dict en lugar de `list[Tool]`). -4. **¿Qué flujo de autonomía (branch, edit, test, commit) es posible hoy?** - Únicamente generación, validación sintáctica básica y ejecución de scripts efímeros. **Ningún flujo de edición del proyecto o Git es posible.** -5. **¿Qué falta para "mejorar el propio RuneScript" de forma autónoma?** - Herramientas MCP para: - - Lectura/Escritura/Edición de archivos del repositorio (`read_file`, `write_file`, `apply_diff`). - - Gestión de Git (`git_branch`, `git_commit`, `git_push`, `create_pr`). - - Ejecución de pruebas automáticas (`run_tests`). - - Un sandbox real de ejecución aislada. -6. **¿Es esta rama "production-ready" para agentes o sigue en MVP?** - **Sigue en MVP / Alpha inicial.** -7. **¿Hay tests end-to-end con un cliente MCP?** - **SÍ**, creados en esta auditoría bajo `cognito-stack/mcp-servers/runescript/scripts/`. -8. **¿La rama `redgreenrefactor` es mergeable a `main` o está muy divergida?** - **Muy divergida** (406 archivos cambiados, +47k lineas). Requiere merge/rebase cuidadoso. -9. **¿Hay CI en esta rama? ¿Pasa?** - **NO hay CI** (no existe la carpeta `.github/workflows`). -10. **¿Hay Dockerfile o docker-compose para levantar el MCP aislado?** - **NO** existe Dockerfile ni docker-compose para el MCP server. - ---- - -## 8.

Recomendaciones Priorizadas - -### P0 (Bloqueantes / Inmediatos) -1. Integrar formalmente la carpeta `cognito-stack/mcp-servers/runescript` en `redgreenrefactor`. -2. Fijar la versión del paquete `mcp` en `requirements.txt` (ej. `mcp>=1.30.0,<2.0.0`) y actualizar las llamadas a la API SDK. -3. Corregir permanentemente la capa del `wrapper.py` para sincronizar las rutas de importación con la estructura real de `redgreenrefactor` (`src.models.ai_assistant.AIAssistant`). - -### P1 (Autonomía de Agente con Hermes) -1. **Implementar herramientas de archivos**: Exponer `read_file`, `write_file`, `list_directory`. -2. **Implementar herramientas de Git**: Exponer `git_checkout_branch`, `git_commit_changes`, `git_push`. -3. **Implementar herramienta de testing**: Exponer `run_project_tests` para permitir ciclos TDD autónomos. +## 4. Arquitectura de Seguridad y Sandboxing -### P2 (Seguridad y Producción) -1. **Sandboxing real**: Envolver `execute_script` dentro de un contenedor Docker o entorno aislado (ej. nsjail / bubblewrap). -2. **Gestión de secretos y Rate Limiting**: Filtrar variables de entorno sensibles en subprocess y añadir Throttling/Rate-Limiter a nivel de llamadas MCP. -3. **Configuración de CI y Dockerization**: Crear `.github/workflows/mcp_ci.yml` y un `Dockerfile` para empaquetar el server MCP. +1. **Perfil `untrusted` (`execute_script`)**: + - `--network=none`, `--read-only`, `--cap-drop=ALL`, `--user=10001:10001`, `--tmpfs /tmp:rw,noexec,nosuid,size=64m`, `--memory=256m`, `--cpus=1`, `--pids-limit=64`. +2. **Perfil `trusted-tests` (`run_tests`)**: + - Monta `RUNESCRIPT_PATH` como `:ro`, `--tmpfs /tmp:rw,exec,nosuid,size=256m`, `PYTHONDONTWRITEBYTECODE=1`, `pytest --cache-dir=/tmp/.pytest_cache`. +3. **Resguardo contra Path Traversal**: + - Todos los paths se resuelven contra `RUNESCRIPT_PATH` mediante `os.path.realpath()`. Cualquier intento de salir del repositorio lanza `PermissionError`. +4. **Respaldos Automáticos**: + - Modificar o sobrescribir archivos mediante `fs_write_file` o `fs_apply_diff` genera automáticamente una copia pre-escritura en `.nia/backups/`. +5. **Rate Limiting y Rotación de Logs**: + - Rate limiter de ventana deslizante configurado por defecto en 60 llamadas/minuto por tool (`RUNESCRIPT_MCP_RATE_LIMIT`). + - Logging con `RotatingFileHandler` (10MB por archivo, 5 respaldos). --- -## 11.
