Prepare X posts with Claude.

Custom connectors run from Anthropic's cloud, so they only work with a server that is reachable on the internet (not localhost). Plans: Free (one custom connector), Pro, Max, Team and Enterprise.

Pro, Max or Free:

1. Open Customize > Connectors (claude.ai/customize/connectors). Older guides and some Desktop builds call it Settings > Connectors.
2. Choose Add custom connector (+).
3. Paste https://heyeveryone.ai/mcp.
4. Leave Advanced settings alone. Claude picks the right client registration for heyeveryone on its own ("Use Claude's published identity").
5. Click Add, then Connect. heyeveryone opens: sign in, tick the workspaces Claude may use, and click Connect.
6. In a chat, turn the connector on from the tools menu. Try the Plan my week or What needs me prompt.

Team or Enterprise:

1. An Owner adds the connector once for the organization: Organization settings > Connectors > Add > Custom > Web, then paste the URL.
2. Each member then clicks Connect under Customize > Connectors. Everyone signs in with their own heyeveryone account.

Good to know:

• The OAuth callback Claude uses is https://claude.ai/api/mcp/auth_callback.
• A personal access token only works through the Request headers beta, which few organizations have: header Authorization, value Bearer hey_pat_.... It can't be combined with OAuth. To change it, remove and re-add the connector.
• Claude Desktop uses the same connectors for remote servers. Anthropic's docs describe no way to put a remote URL in claude_desktop_config.json. - The community bridge `mcp-remote` works but isn't needed: "command": "npx", "args": ["mcp-remote", "https://heyeveryone.ai/mcp"].
