+
+## Project Overview
+- Purpose: Guillotina core framework and official contrib addons.
+- Main stack: Python async API server (ASGI), PostgreSQL, optional Redis.
+- Key paths:
+  - `guillotina/` core framework and contrib packages
+  - `guillotina/tests/` test suite
+  - `docs/source/` documentation
+
+## Development Commands
+- Setup (local venv expected at repo root):
+  - `python3 -m venv .venv`
+  - `source .venv/bin/activate`
+  - `pip install -r requirements.txt`
+  - `pip install -r contrib-requirements.txt`
+  - `pip install -e '.[test]'`
+- Run local server:
+  - `g` (uses `config.yaml` by default)
+- Run tests:
+  - `.venv/bin/pytest guillotina/tests`
+  - Targeted: `.venv/bin/pytest guillotina/tests/<path>`
+
+## Validation
+- For contrib changes, run focused tests under the touched contrib test folder.
+- For API/service changes, verify status codes and response payload contracts.
+- Keep docs updated under `docs/source/contrib/` when adding contrib features.
+
+## Deployment Notes
+- This repo is a framework/library; no direct client deployment from this repo by default.
+- Build/release lifecycle should follow package versioning (`VERSION`, `CHANGELOG.rst`).
+
+## Constraints / Gotchas
+- Keep compatibility with repository formatting (`black` line length 110).
+- Avoid wrapper layers when task explicitly requires low-level protocol primitives.
+- Never commit credentials or local environment files.
+
+## Task Closeout Notes
+- Update `CHANGELOG.rst` for notable changes.
+- Record branch name, commit hash, validation output, and task evidence in Ops Tracker.
+

 7.0.7 (unreleased)
 ------------------
 
+- REAKING CHANGE: Drop support for Python 3.8 and 3.9. Guillotina is
+  now tested and supported on Python 3.10, 3.11, and 3.12.
+  [nilbacardit26]
+- Add `guillotina.contrib.mcp` with low-level MCP server integration
+  (`mcp.server.lowlevel`), tool registry utility, MCP services,
+  cache invalidation subscribers, and tests/docs coverage.
+- Optimize MCP `list_children` tool to prefer catalog queries and
+  fallback to `async_items` when catalog is unavailable.
+- Upgrade the pytest stack so the CI test environment stays compatible
+  with the optional MCP SDK and its AnyIO pytest plugin on Python 3.10+.
+  [finalchaz, nilbacardit26]
 - Docs: Update documentation and configuration settings
 - Chore: Update sphinx-guillotina-theme version to 1.0.9

+# MCP
+
+`guillotina.contrib.mcp` provides a low-level MCP integration layer built on
+the official `mcp.server.lowlevel` primitives (no FastMCP wrapper).
+
+## Installation
+
+```bash
+pip install "guillotina[mcp]"
+```
+
+## Configuration
+
+```yaml
+applications:
+  - guillotina
+  - guillotina.contrib.mcp
+
+mcp:
+  enabled: true
+  server_name: guillotina-mcp
+  default_child_limit: 50
+```
+
+## Runtime endpoints
+
+- `GET /@mcp`: registry metadata and registered tools.
+- `GET /@mcp/tools`: tool list and schemas.
+- `POST /@mcp/tools/invoke`: executes one tool with payload
+  `{ "tool": "<name>", "arguments": { ... } }`.
+- `GET /@mcp/server/status`: validates low-level SDK availability.
+
+## Built-in tools
+
+- `resolve_path`: resolve a path and return basic metadata.
+- `list_children`: list child resources from a folder-like resource.
+- `serialize_resource`: execute Guillotina serialization adapters.
+- `notify_modified`: emit an `ObjectModifiedEvent`.
+
+The tool registry is implemented as a Guillotina utility and cache invalidation
+is handled by subscribers on object add/modify/remove events.
+
+`list_children` prefers catalog-backed lookup when a catalog utility is
+available and falls back to `async_items()` iteration when it is not.
