CRITICAL FIX - Database Parameter (graphiti_core):
- Fixed graphiti_core/driver/neo4j_driver.py execute_query method
- database_ parameter was incorrectly added to params dict instead of kwargs
- Now correctly passed as keyword argument to Neo4j driver
- Impact: All queries now execute in configured database (not default 'neo4j')
- Root cause: Violated Neo4j Python driver API contract
Technical Details:
Previous code (BROKEN):
params.setdefault('database_', self._database) # Wrong - in params dict
result = await self.client.execute_query(cypher_query_, parameters_=params, **kwargs)
Fixed code (CORRECT):
kwargs.setdefault('database_', self._database) # Correct - in kwargs
result = await self.client.execute_query(cypher_query_, parameters_=params, **kwargs)
FIX - Index Creation Error Handling (MCP server):
- Added graceful handling for Neo4j IF NOT EXISTS bug
- Prevents MCP server crash when indices already exist
- Logs warning instead of failing initialization
- Handles EquivalentSchemaRuleAlreadyExists error gracefully
Files Modified:
- graphiti_core/driver/neo4j_driver.py (3 lines changed)
- mcp_server/src/graphiti_mcp_server.py (12 lines added error handling)
- mcp_server/pyproject.toml (version bump to 1.0.5)
Testing:
- Python syntax validation: PASSED
- Ruff formatting: PASSED
- Ruff linting: PASSED
Closes issues with:
- Data being stored in wrong Neo4j database
- MCP server crashing on startup with EquivalentSchemaRuleAlreadyExists
- NEO4J_DATABASE environment variable being ignored
