Universal DB MCP — 17 Databases, Read-Only Default

Main

• Use read-only mode first: validate schema access and Text2SQL accuracy before enabling any write permissions.

• Pick your transport based on deployment: stdio for local MCP hosts; Streamable HTTP/SSE when you need remote connections (Dify, services).

• For large schemas, rely on caching and batch schema retrieval; README includes a table showing 25x–100x improvements as table counts grow.

Source-backed notes

• README claims “17 database support” and lists MySQL/PostgreSQL/Redis/Oracle/SQL Server/MongoDB/SQLite plus additional vendors.
• README states read-only is the default and describes permission modes for write operations.
• README shows two startup modes (stdio/http) and multiple access methods (MCP stdio, SSE, Streamable HTTP, REST API).

FAQ

• Is write access enabled by default?: No — README says read-only is the default and write permissions must be explicitly enabled.
• Which transport should I choose?: Use stdio for local Claude Desktop/Cursor; use Streamable HTTP/SSE for remote deployments.
• How does it handle large schemas?: README documents schema caching and batch retrieval, with a performance table up to 100x improvements.
