Client coverage note	Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server.
Access and data
Authentication	MariaDB database credentials; separately configured FastMCP authentication is available when exposing HTTP/SSE transports.	Authentication depends on the database source and can include database username/password, Google Cloud IAM, or other source-specific mechanisms. Use a dedicated read-only identity and secret manager or protected environment variables.
Cost	No separate MCP fee is documented. External embedding providers can have their own usage charges.	The Apache-licensed Toolbox and npm server have no documented MCP usage fee. Database services, Google Cloud resources, network transfer, observability backends, hosting, and the AI client may incur normal charges.
Permissions	Effective authority is the MariaDB database user's privileges. `MCP_READ_ONLY` is an application-level guard; the project recommends a dedicated least-privilege database user for true read-only protection.	Effective permissions come from each configured database identity and the enabled prebuilt or custom tools. Generic prebuilt sets can include schema discovery and execute_sql; custom tools can constrain statements, parameters, and accessible sources.
Data handling	Queries operate on the connected MariaDB database. Optional vector-store tools can send text to the configured embedding provider (OpenAI, Gemini, or local Hugging Face model depending on configuration).	The Toolbox process connects directly to configured databases and returns selected schemas, rows, query results, and errors to the MCP client. Credentials may be supplied through environment variables or configuration; integrated cloud authentication and OpenTelemetry are available.
Limitations
Tradeoffs	Shortlist evidence is sufficient for identity, setup and task value; authenticated runtime tool-schema measurement and exhaustive security certification remain out of scope.	Prebuilt tools are quick to adopt but may expose generic execute_sql capability; custom tools require more design but provide a narrower contract. The npx path is convenient but the publisher recommends binary or container installation for standard reliable deployments. Supporting many database engines increases configuration flexibility and operational complexity.
Risk context	The server includes database-creation and optional vector-store create/delete/insert tools. Mis-scoped database credentials can expose or modify production data.	Generic SQL tools can expose or mutate large amounts of data and retrieved database text can carry prompt-injection content. Prefer a non-production replica, read-only credentials, allow-listed custom parameterized tools, query limits, audit logs, and no secrets in config. This review does not claim MCP100 execution testing.
