28-32: 🛠️ Refactor suggestion

Consider combining apt-get update and install in the same RUN instruction.

Separating apt-get update from apt-get install can lead to inconsistency issues if the Docker build cache is used, as you might end up installing packages from an outdated package list. While this change fixes the previous syntax, it introduces a potential problem.

-RUN apt-get update
-
-RUN apt-get install -y \
-  gcc \
-  libpq-dev
+RUN apt-get update && apt-get install -y \
+  gcc \
+  libpq-dev

88-105: Development section instructions look good.

The new development section provides clear steps for using a local build of the cognee library. The instructions are comprehensive and will improve the developer experience when working with local changes.

Consider these minor improvements:

-In order to use local cognee build, run in root of the cognee repo:

alembic/versions/8057ae7329c2_initial_migration.py (1)

1-27: Initial migration implementation looks correct.

The migration properly handles database creation and deletion using the sqlalchemy engine. The use of await_only correctly bridges the gap between the synchronous Alembic framework and asynchronous database operations.

Consider adding minimal error handling and logging for better diagnostics during migration:

 def upgrade() -> None:
     db_engine = get_relational_engine()
-    await_only(db_engine.create_database())
+    try:
+        await_only(db_engine.create_database())
+        print("Database created successfully")
+    except Exception as e:
+        print(f"Error creating database: {e}")
+        raise


 def downgrade() -> None:
     db_engine = get_relational_engine()
-    await_only(db_engine.delete_database())
+    try:
+        await_only(db_engine.delete_database())
+        print("Database deleted successfully")
+    except Exception as e:
+        print(f"Error deleting database: {e}")
+        raise

16-20: Potential inconsistency in revision dependencies

I noticed that both down_revision and depends_on are set to the same value "8057ae7329c2". Typically, down_revision is used to specify the previous revision in a linear migration path, while depends_on is used for non-linear dependencies. Having both set to the same value is redundant.

- down_revision: Union[str, None] = "8057ae7329c2"
- depends_on: Union[str, Sequence[str], None] = "8057ae7329c2"
+ down_revision: Union[str, None] = "8057ae7329c2"
+ depends_on: Union[str, Sequence[str], None] = None

27-28: Consider adding error handling for user deletion

The downgrade function should handle the case where the user doesn't exist.

def downgrade() -> None:
-    await_only(delete_user("default_user@example.com"))
+    try:
+        await_only(delete_user("default_user@example.com"))
+    except Exception as e:
+        if "UserNotFound" in str(e) or "User not found" in str(e):
+            # User might have been manually deleted, this is fine
+            pass
+        else:
+            # Re-raise other exceptions
+            raise

---

13-13: Consider using a constant for the default email

The default email "default_user@example.com" is used in the downgrade function but not defined as a constant, creating potential for inconsistency with the create_default_user function.

from cognee.modules.users.methods import create_default_user, delete_user
+
+# This should match the default in create_default_user
+DEFAULT_USER_EMAIL = "default_user@example.com"

# ...

def downgrade() -> None:
-    await_only(delete_user("default_user@example.com"))
+    await_only(delete_user(DEFAULT_USER_EMAIL))

cognee-mcp/entrypoint.sh (4)

3-3: The script uses set -e without set -o pipefail

While set -e ensures the script exits on error, it doesn't catch errors in pipelines. This could lead to silent failures in piped commands.

- set -e  # Exit on error
+ set -e      # Exit on error
+ set -o pipefail  # Exit on error in pipeline

---

16-24: Consider additional retries for database migrations

The script handles the case where the default user already exists but doesn't implement retries for other temporary database connection issues that might occur during migration.

Consider adding a retry mechanism for other transient errors:

- MIGRATION_OUTPUT=$(uv run alembic upgrade head 2>&1) || {
-     if [[ $MIGRATION_OUTPUT == *"UserAlreadyExists"* ]] || [[ $MIGRATION_OUTPUT == *"User default_user@example.com already exists"* ]]; then
-         echo "Warning: Default user already exists, continuing startup..."
-     else
-         echo "Migration failed with unexpected error:"
-         echo "$MIGRATION_OUTPUT"
-         exit 1
-     fi
- }
+ # Initialize retry counter
+ RETRY_COUNT=0
+ MAX_RETRIES=3
+ 
+ while [ $RETRY_COUNT -lt $MAX_RETRIES ]; do
+     MIGRATION_OUTPUT=$(uv run alembic upgrade head 2>&1) && break
+     
+     # Check for known acceptable errors
+     if [[ $MIGRATION_OUTPUT == *"UserAlreadyExists"* ]] || [[ $MIGRATION_OUTPUT == *"User default_user@example.com already exists"* ]]; then
+         echo "Warning: Default user already exists, continuing startup..."
+         break
+     # Check for connection errors that might be temporary
+     elif [[ $MIGRATION_OUTPUT == *"connection"* ]] || [[ $MIGRATION_OUTPUT == *"timeout"* ]]; then
+         RETRY_COUNT=$((RETRY_COUNT+1))
+         echo "Database connection issue. Retry $RETRY_COUNT of $MAX_RETRIES in 5 seconds..."
+         sleep 5
+     else
+         echo "Migration failed with unexpected error:"
+         echo "$MIGRATION_OUTPUT"
+         exit 1
+     fi
+ done
+ 
+ if [ $RETRY_COUNT -eq $MAX_RETRIES ]; then
+     echo "Failed to run migrations after $MAX_RETRIES retries. Last error:"
+     echo "$MIGRATION_OUTPUT"
+     exit 1
+ fi

31-41: Consider checking for required environment variables

The script doesn't validate if required environment variables are set before starting the application.

Add environment variable validation:

+ # Check for required environment variables
+ REQUIRED_VARS=("DATABASE_URL" "SECRET_KEY")
+ MISSING_VARS=false
+ 
+ for VAR in "${REQUIRED_VARS[@]}"; do
+     if [ -z "${!VAR}" ]; then
+         echo "Error: Required environment variable $VAR is not set"
+         MISSING_VARS=true
+     fi
+ done
+ 
+ if [ "$MISSING_VARS" = true ]; then
+     exit 1
+ fi
+
# Modified Gunicorn startup with error handling
if [ "$ENVIRONMENT" = "dev" ] || [ "$ENVIRONMENT" = "local" ]; then
    if [ "$DEBUG" = "true" ]; then

---

32-41: Redundant exec cognee call for production environment

The script has duplicate exec cognee statements for the production path.

if [ "$ENVIRONMENT" = "dev" ] || [ "$ENVIRONMENT" = "local" ]; then
    if [ "$DEBUG" = "true" ]; then
        echo "Waiting for the debugger to attach..."
        exec python -m debugpy --wait-for-client --listen 0.0.0.0:5678 -m cognee
    else
        exec cognee
    fi
else
-    exec cognee
+    # Production mode
+    exec cognee
fi

cognee-mcp/Dockerfile (3)

25-25: Multiple files copied to the same destination

The COPY command is copying multiple files to the same destination (./), which can be confusing and error-prone.

Split this into separate COPY commands for clarity:

- COPY ./cognee-mcp/pyproject.toml ./cognee-mcp/uv.lock ./cognee-mcp/entrypoint.sh ./
+ COPY ./cognee-mcp/pyproject.toml ./pyproject.toml
+ COPY ./cognee-mcp/uv.lock ./uv.lock
+ COPY ./cognee-mcp/entrypoint.sh ./entrypoint.sh

---

34-36: Consider using relative paths for Alembic configuration

The Alembic configuration is copied using absolute paths, which might cause issues if the directory structure changes.

- # Copy Alembic configuration
- COPY alembic.ini /app/alembic.ini
- COPY alembic/ /app/alembic
+ # Copy Alembic configuration
+ COPY alembic.ini ./alembic.ini
+ COPY alembic/ ./alembic

---

20-22: Consider using multi-stage build for system dependencies

The current Dockerfile installs system dependencies in the build stage, but these might also be needed in the final image.

To ensure consistency, consider installing the same dependencies in both stages:

# Install system dependencies
RUN apt-get update && apt-get install -y \
    gcc \
    libpq-dev

# ... (later in the file)

FROM python:3.12-slim-bookworm

WORKDIR /app
+
+# Install runtime dependencies
+RUN apt-get update && apt-get install -y \
+    libpq-dev \
+    && rm -rf /var/lib/apt/lists/*

COPY --from=uv /root/.local /root/.local
