Field-by-field comparison

Compare the evidence before choosing an MCP.

Each signal stays separate, missing facts remain visible, and the column order follows your selection.

Task fit
Best for
  • High-volume analytical database exploration and query workflows for ClickHouse deployments.
  • Inspecting one Supabase project's schema, logs, advisors, and docs
  • Development environments using project-scoped read-only access
  • Teams that understand database and deployment consequences
Not ideal for
  • Teams outside the publisher ecosystem or without least-privilege credentials
  • Production database administration by an unattended agent
  • Users needing only public Supabase documentation
  • Organizations unable to grant Supabase OAuth access to an MCP client
Avoid when
  • The connected identity is broader than the task requires
  • Tool calls cannot be reviewed before consequential mutations
  • The server would be left organization-wide rather than project-scoped
  • Write-capable SQL, migrations, functions, branches, or storage changes cannot be human-approved
  • Production secrets or customer records could be returned to the model

Access and data
AuthenticationThe official server uses configured ClickHouse connection credentials and supports secure deployment settings.Hosted MCP uses browser OAuth and grants organization access to the MCP client. Project scope, read-only mode, and feature groups are encoded in URL query parameters. Enterprise-managed authentication is GA for eligible Team and Enterprise organizations. Access remains scoped to each user's existing Supabase role and permissions.
CostThe MCP integration has no separately verified MCP100 price conclusion. Publisher subscriptions, API usage, compute, storage, and AI-client charges may apply.The MCP server is open source; normal Supabase plan, database, branch, Edge Function, storage, and usage charges apply. Branching and some storage operations require a paid plan.
PermissionsThe configured ClickHouse user's grants and RBAC define the authoritative accessible schemas and queries. MCP-side general writes require CLICKHOUSE_ALLOW_WRITE_ACCESS, and DROP, TRUNCATE, DELETE, and similar destructive operations require the additional CLICKHOUSE_ALLOW_DROP control.Without project_ref the hosted server can access all projects in the authorized organization. With project_ref it is limited to one project. read_only=true uses a read-only Postgres user for SQL and disables listed mutation tools. Feature groups can further narrow exposed tools.
Data handlingAuthorized service data and tool results pass through the MCP server to the connected AI client. Review the publisher and client data policies before using sensitive data & databases information.Enabled tools may return schemas, table data from executed queries, logs, security/performance advisors, project metadata, publishable keys, types, and Edge Function source. Hosted mode sends tool requests through Supabase's MCP service.
Limitations
Tradeoffs
  • Queries can expose large or sensitive datasets and consume cluster capacity even when writes are disabled.
  • Project scoping removes account-level tools but materially reduces blast radius.
  • Read-only mode disables mutations but also removes migration, deployment, branch, and storage configuration workflows.
  • Branching and some storage capabilities require paid plans; the server is pre-1.0 and may change.
Risk contextMCP-side write and destructive opt-ins are safety controls, not the primary security boundary. Queries can expose large or sensitive datasets and consume cluster capacity. Use a narrowly privileged ClickHouse identity, least-privilege grants/RBAC, narrowly enabled tools, and explicit confirmation for mutations even when destructive controls are disabled.Unscoped or write-enabled access can affect every project in an organization, execute SQL, apply migrations, deploy functions, or manage branches. Always set project_ref and read_only=true first, minimize feature groups, and avoid production data.
