Best for
  • PostgreSQL developers needing deep performance analysis and index tuning
  • DBAs who need read-only access and health checks in production
  • Teams that want AI assistants to help with database optimization and monitoring
  • Teams already using ClickHouse who want AI assistants to access data directly.
  • Scenarios requiring fast, read-only data queries and schema exploration.
Not for
  • Users needing full write access but wanting safety controls (restricted mode is read-only)
  • Users of non-PostgreSQL databases
  • Users needing real-time monitoring or alerting (this tool is analytical)
  • Scenarios requiring write access to the database without explicit opt-in.
  • Production environments with stringent security requirements that avoid default permission settings.
Required permissions
  • Database connection credentials (connection URI)
  • Read-write or read-only database access (depending on access mode)
  • Optional: permission to load extensions (pg_stat_statements, hypopg)
  • Optional: OpenAI API key for experimental LLM index tuning
  • Requires read-only access to ClickHouse database (default).
  • Optional: write access via CLICKHOUSE_ALLOW_WRITE_ACCESS.
  • Optional: destructive operations via CLICKHOUSE_ALLOW_DROP.
Risks and side effects
  • Unrestricted mode can allow SQL that might damage or delete data
  • SQL parsing may not prevent all bypasses of read-only restrictions if unsafe procedural languages are enabled
  • Connection credentials may be stored in plaintext in MCP client configuration
  • Index tuning search may consume significant database resources
  • If write access is enabled, AI might make unintended modifications.
  • If DROP access is enabled, data deletion could occur accidentally.
  • Credentials may be exposed via environment variables.
