Side-by-side MCP evidence comparison
Evidence field	Atlan Data CatalogWatchlist candidate	Google MCP Toolbox for DatabasesMCP100 Selected
Task fit
Best for	Atlan customers who want governed catalog search, lineage, SQL/context and metadata curation under existing Atlan permissions.	Schema exploration and database-aware coding in development environments Connecting one MCP layer to supported Google Cloud and third-party databases Defining structured, parameterized database tools with integrated authentication and observability
Not ideal for	Organizations without clearly governed Atlan roles/personas or that cannot expose catalog metadata to an external AI client.	Unrestricted natural-language SQL against production data Teams unwilling to operate and secure a local or hosted Toolbox process
Avoid when	Do not use an over-privileged service-account/persona when a narrower user role can satisfy the workflow.	The configured database user can modify production data or schema beyond the approved task Sensitive query results cannot be sent to the AI client Credentials would be committed in tools.yaml or MCP configuration

Client coverage note	Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server.
Access and data
Authentication	Publisher supports authenticated tenant access via OAuth and supported API/service tokens.	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	Atlan plan/entitlement and AI-provider costs apply.	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	Inherits Atlan persona/role/domain permissions; service-account tokens are tied to a defined persona according to publisher docs.	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	Atlan states MCP retrieval is real-time without an intermediate MCP cache and that MCP itself does not send customer data to an LLM; the connected AI client/provider still receives whatever tool results the user sends into that conversation.	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	Promising signal, but it ranks below the current Selected/Watchlist admission cohort on maturity, uniqueness, publisher trust, security clarity, or MCP-native evidence.	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	Sensitive enterprise metadata and any authorized curation writes remain the key governance concerns.	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.
