Starter prompt

Prompt
Publish one piece of content everywhere. Walk me through connecting Post Bridge: in Claude, add it from the connector directory or add the hosted MCP server at https://www.post-bridge.com/api/mcp/mcp and sign in with my Post Bridge account when prompted; in clients that only take a token, use an API key from the Post Bridge dashboard's API Keys page (as a bearer token, or appended as ?key=API_KEY to the MCP URL). The API reference is at https://api.post-bridge.com/reference. Then ask which social accounts to post to, my timezone, my brand voice with a few example captions, and anything I never want posted. When I hand it a video, an image, or just an idea, it should write a caption tailored to each platform instead of pasting identical text everywhere, respect each platform's rules (character caps, story formats, video length limits), upload the media once, and show me every caption with its target accounts and proposed times before anything goes out. Schedule only what I approve and save anything ambiguous as a draft. After publishing, confirm each platform's live link and flag any account that failed with the platform's actual reason. Do the first post with me watching, then save it.
