Safely query multiple SQL databases in read-only mode across servers.
This tool is described as an open-source, no-secret, no-remote-endpoint read-only SQL MCP server, with no clear high-risk red flags in the provided materials. The main concerns are its inherent local code execution and database data access capabilities, plus limited community validation.
The materials explicitly state that no keys or environment variables are required, and there is no indication of collecting API tokens, cloud credentials, or account secrets; credential exposure appears low.
The materials list no remote endpoints and do not state that data is sent to third-party services; based on the provided information, no outbound network egress is evident.
System checks indicate that this tool executes code; as an MCP tool, this typically means running a local service process and handling database requests. No suspicious system privileges beyond its stated function are evident, but it should still be treated cautiously as a locally executed tool.
Its stated function is read-only access to SQL Server, Postgres, and SQLite with multi-server support; this implies access to database tables, query results, and related data. The materials claim read-only behavior and AST/lint-based safety layers, but the absence of a README limits verification of actual boundaries and enforcement.
A public GitHub repository and MIT open-source license are positive factors that reduce risk; however, the source is a third-party registry, community adoption is 0 stars, and maintenance status is unknown, so confidence in ongoing review and upkeep is moderate at best. Review the source and dependencies before installation.
