How does an organization relate to a project?

The org owns the projects. An organization is the top-level account; projects, and on Atlas clusters, live inside it. An agent often lists orgs first to get the scope, then lists projects within the org it means to work in.

Why list organizations at all?

To scope and to confirm access. An agent working across multiple accounts needs the org id to target the right one, and listing is also a check that the connection reaches the accounts you expect. It is the first navigation step on a multi-org platform.

MCP servers that can list organizations

3 verified servers expose a tool that can list organizations

On the platforms an agent works against, an organization is the top of the hierarchy: the account that owns the projects, the databases, the billing. Listing organizations returns the ones the connection can reach, so an agent knows which accounts are in scope before it drills into a project.

These verified servers let an agent list the organizations it has access to.

Top pick

Supabase

Supabase (community)

Community

Connects agents to a Supabase project: run SQL, inspect schema, read logs, and manage edge functions.

databases2,710

Tool:

list_organizations

Supabase's list_organizations returns every organization the user belongs to, the top of the hierarchy above the account's projects.

Pick 2

Neon

Official

Neon's official MCP server lets agents create projects and branches, run SQL, and drive safe schema migrations on serverless Postgres.

databases606

Tool:

list_organizations

On Neon, list_organizations returns the organizations the account can reach, the scope an agent confirms before it lists or touches projects.

Pick 3

MongoDB

Official

MongoDB's official MCP server: query and manage databases, plus Atlas cluster administration.

databases1,039

Tool:

atlas-list-orgs

atlas-list-orgs lists the MongoDB Atlas organizations that projects and clusters hang off, the outermost grouping in the Atlas hierarchy.

What to know

An organization is the outermost container, and listing it is the first step when an agent works across more than one account. Above projects and databases sits the org, and the agent often needs its id to scope a list-projects call or to know which account a resource belongs to. The platforms here return the orgs the authenticated user is a member of: Supabase and Neon the organizations on the account, MongoDB Atlas the orgs that projects and clusters live under. It doubles as a scope check, a way to confirm the connection reaches the accounts you expect and no others.

Org membership rarely changes, so an agent that learns which organizations it can reach does not need to re-list every session. Holding that, and which org owns which project, lets it navigate straight to the right account instead of walking the hierarchy from the top each time.
