Claude Desktop

Claude Desktop can use Plushcap as a remote custom connector. Anthropic's documented remote-connector interface supports OAuth but does not expose a setting for an arbitrary Bearer header.

Connect with OAuth

For an individual Free, Pro, or Max account:

1. Open Customize → Connectors.
2. Select the plus button, then Add custom connector.
3. Name the connector Plushcap and enter:

text https://mcp.plushcap.com/mcp

1. Select Add, then Connect.
2. Complete the Plushcap authorization flow in your browser.

For Team and Enterprise organizations, an Owner must first add the custom web connector from Organization settings → Connectors. Members can then connect their own Plushcap account.

Bearer-token limitation

Plushcap accepts API keys as Bearer tokens, but Claude Desktop's documented remote-connector UI does not accept custom request headers. Do not paste an API key into Claude. For persistent API-key authentication, use Claude Code, Codex CLI, or another header-capable client.

Verify

Enable Plushcap for the conversation from the Connectors menu and ask:

Use Plushcap to find recent company engineering posts about AI agents.

If connection fails, confirm the endpoint is public, includes /mcp, and that your organization permits custom connectors.
