v1.4.0

Added

• Read-only query tools (Phase 1): query_sql, query_influxql, list_tables, describe_table, and investigate_database, each enforcing read-only access at the tool boundary
  • New QuerySafetyService validates queries against an allow list (SELECT, SHOW, EXPLAIN, WITH for SQL; SELECT, SHOW for InfluxQL) and rejects write/DDL statements before they reach InfluxDB
  • Row limit enforcement: default 1000 rows, hard max 5000, applied consistently across query paths including outer-query limits on wrapped queries
  • Query routing options forwarded through to the underlying query execution (e.g. per-request timeout, query parameters)
  • New TelemetryService logs tool-boundary events (request id, query id, duration, row count, truncation, success/error code) to a local telemetry file
• Enterprise/Core Retention Policy Support: Added database retention policy configuration for Core/Enterprise instances via update_database tool
  • New method updateDatabaseCoreEnterprise() in DatabaseManagementService for PUT /api/v3/configure/database
  • Support for retentionPeriod parameter on Core/Enterprise (sent as retention_period, a humantime duration string such as "60d")
  • Warning when unsupported parameters (maxTables, maxColumnsPerTable) are provided for Core/Enterprise
  • Enhanced tool description to indicate Core/Enterprise support for retention configuration

Fixed

• Query routing options (timeout, parameters) are now forwarded correctly instead of being dropped
• Outer query limits are now enforced on wrapped/nested queries, not just top-level queries

Enhanced

• Tool Availability: Updated update_database from "Cloud Dedicated only" to "All versions"
  • Cloud Dedicated: supports maxTables, maxColumnsPerTable, retentionPeriod
  • Core/Enterprise: supports retentionPeriod only
• Documentation: Added retention policy examples for Enterprise and common retention period reference table
