Side-by-side MCP evidence comparison
Evidence field	Prisma Postgres MCPWatchlist candidate	Supabase MCPMCP100 Selected
Task fit
Best for	Managing Prisma Postgres workspaces and databases from an AI client in controlled environments Teams that can require explicit review for database/object-store changes	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	Production accounts where the AI client should not create/delete managed resources Organizations that require a read-only database assistant	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 workspace contains production buckets/databases without separate safeguards Users might approve irreversible bucket deletion without independent confirmation	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
Authentication	Hosted HTTP server authenticates through Prisma Console on first use and grants access to the workspace the user selects.	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.
Cost	Prisma Postgres / object-store plan and usage pricing applies.	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.
Permissions	Permissions follow the authenticated Prisma workspace/account. Tools include resource creation and access-key management, not just read operations.	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 handling	Can read workspace/database metadata and manage Prisma Postgres databases and object-store resources, including permanent bucket deletion.	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	OAuth and hosted management simplify setup The same tool surface can create resources, generate access keys, and permanently delete object storage	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 context	High. Permanent deletion, database creation, and credential generation are consequential. Require explicit human confirmation and separation from production where possible.	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.
