Connect Claude web

Use Claude's custom connector to review your schedule and prepare publications from a conversation. Your Claude account or organization must allow custom connectors.

Add the connector

1. Open Claude's Customize → Connectors, or Settings → Connectors in interfaces that use that label.
2. Choose Add custom connector, name it OpenPost, and enter:

https://app.openpo.st/mcp

3. Add the connector and complete OpenPost's browser sign-in. Leave optional client credentials empty; OpenPost supports dynamic registration.
4. Choose read-only access for reviews, or full access to create and publish. Enable OpenPost in the conversation's connector controls.

Check the connection

Ask, “List my OpenPost workspaces,” then name one and ask for its scheduled publications. For a first write, request an unpublished draft and inspect it in OpenPost.

If it does not connect

An organization owner may need to add or allow the connector first. Claude reaches remote servers from its cloud, so self-hosted OpenPost needs a public HTTPS URL. Reconnect from the connector settings if authorization expires.

Using another Claude client? See Claude Desktop or Claude Code.
