Claude and Cowork
Regular Claude and Cowork use the hosted MCP connector. In Claude’s connector settings, add a custom connector with the URL above and complete OAuth in the browser. Your plan and organisation settings must allow custom connectors; an administrator may need to enable access. Ask the connected assistant to callget_status and report the active account
and its readiness without making changes. Follow Manage ads
for buying, selling, and reporting workflows.
The apostra-developer plugin is for Codex and Claude Code. Its installation
commands run in those coding tools, not in regular Claude or Cowork. Use the
developer quickstart when you want to build software.
Existing connections
If you already use a v2 Buyer or Seller connector, add v3 as a separate connection while checking your workflow. Selecting v3 in these docs does not change a client configuration or grant additional permissions. A plugin that already supplies the endpoint does not need a second manually added connector. The server can close a connection after 30 minutes or during a deploy. Reuse the existing MCP session when reconnecting. Do not design long-running work around one open tool call. If a call is interrupted, its response may be lost even when the operation was accepted. Re-read state and follow that tool’s idempotency contract before retrying.

Review host-specific setup, credential handling, connection lifetime, and
stable v2 connector behavior.
