Distribute and govern Synter

Owners and Primary Owners manage organization plugins in Organization settings → Plugins. Cowork and Skills must both be enabled.

GitHub marketplace distribution

Prepare a private or internal GitHub marketplace repository for organization syncing. Public repositories are not accepted directly for organization marketplaces, so mirror the reviewed Synter plugin folder into the managed repository and reference it with a relative path.
Open Organization settings → Plugins, click Add plugin, choose GitHub, and enter the managed repository as owner/repo. Alternatively, use Add plugins → Upload a file for a reviewed ZIP under 50 MB.
Set Synter to Installed by default, Available for install, Not available, or Required. Enterprise admins can override access by group.
Verify the plugin's hosted connector endpoint and decide which users may access production Synter organizations and ad accounts.

Organization-managed behaviorMembers cannot edit organization-managed plugins. Installed by default plugins may be uninstalled; Required plugins cannot be removed. Available plugins appear in the catalog for self-service installation.

Connector governance

The plugin's connector is a public-internet hosted remote MCP at https://mcp.syntermedia.ai, which is reachable from Anthropic's cloud. Govern who can use custom connectors and plugins under your Claude organization policy, and separately govern which Synter organizations and ad accounts each API key can access.

Require keys to be entered in the protected plugin configuration or, for MCP clients that support custom headers, the X-Synter-Key header—never prompts. Standalone Claude Custom Connector UI cannot set that header.
Test with read-only reporting first and verify returned organization and account IDs.
Document budget, tracking, and live-change approval policy.
Re-check installation preferences after marketplace sync failures.

See Anthropic's Manage plugins for your organization for current admin steps and limits.
