Connections Glossary

Audience: engineers, designers, and agents writing integration code, plans, or product copy on the Apps v2 substrate.

Source: the accepted vocabulary table from the PAP-13211 plan. Treat these definitions as product law when translating old Connections v1, plugin, skill, MCP, and gateway language onto Apps v2.

Canonical Vocabulary

Term	Definition	It is NOT
App	Catalog entry for an external or first-party system: metadata, supported transports, auth modes, and action catalog. The unit of the store.	A running thing; a plugin.
AppDefinition	Versioned, data-only authoring record for an App: identity, copy, supported methods, ownership options, fields, and setup guidance.	A company connection or executable plugin.
Connection	A configured, credentialed instance of an app for this company, possibly per-user account. Carries status and health.	A plugin install; an MCP server config file.
uid	Stable company-scoped connection address in {namespace}/{slug} form.	A database UUID or display name.
Ownership	Who supplies and controls the OAuth client: platform-shared, platform-provisioned, customer, or DCR.	Connection kind or credential ownership.
Subject	The app/workspace or Paperclip user on whose behalf a credential is requested.	The calling agent.
Grant	Credential-bearing authorization for one connection subject and provider tenant.	A profile, rule, or permission bypass.
Trigger	Provider-origin event definition that starts governed Paperclip work.	An unauthenticated webhook handler.
Connector service	Paperclip-operated relay for managed OAuth callbacks, credential custody, and webhook intake at connect.paperclip.ing.	Paperclip ID or the per-company broker.
Action / Tool	One invokable capability of a connection, risk-classified and quarantined when new or changed.	A free-form shell command or permission grant.
Profile	Curated allowlist of actions bound to a scope such as company, project, agent, routine, or issue.	A permission system of its own.
Rule	Allow, ask-first, or block per action. Ask-first lands in the Review queue.	A profile or catalog entry.
Gateway	Named inbound MCP endpoint exposing curated connections/tools to external clients under a scoped bearer token. Reuses profiles and rules.	A new permission model.
Plugin	Code extension package: workers, UI, migrations. May declare apps/providers and provision skills. Packaging, not governance.	An integration per se.
Skill	Instructions an agent follows. May use connections; must not own tokens.	A token store.
MCP	A wire protocol; one transport apps may support.	A product category.
Broker	The run-time service that turns a stored credential plus a grant into a short-lived, downscoped, attributed token.	A vault or a permission model.

Apps v2 Object Mapping

Vocabulary term	Apps v2 object or surface
App	tool_applications, provider gallery cards, app detail metadata.
AppDefinition	Catalog registry source used to author and seed Apps and setup methods.
Connection	tool_connections, connection detail status/health, setup/configure flows.
Grant	connection_grants, provider tenant and subject-specific credential refs.
Action / Tool	Catalog entries discovered from MCP/OpenAPI/vendor wrappers.
Profile	Access profiles and bindings.
Rule	Policy rules such as allow, ask-first, block, rate limit, and trust rules.
Gateway	Inbound MCP gateway sessions and scoped client tokens.
Plugin	Extension packaging that may declare apps but does not bypass governance.
Skill	Agent instruction package that calls governed connections through Paperclip.
MCP	Transport option for apps and gateways.
Broker	Credential resolver/token broker path over company_secrets.

Translation Rules

• MCP is a transport, not the information architecture.
• A plugin may bundle an app, but governance always flows through the connection, profile, rule, broker, and audit model.
• A skill may use Slack, Google Drive, Ramp, or another vendor, but the durable credential belongs in company_secrets and is reached through a connection.
• Inbound clients use scoped Paperclip auth; outbound vendor calls use the Apps v2 connection governance stack.
