That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
@promptjang/mcp-server
Official local MCP server for PromptJang. It exposes bounded delivery and mailbox tools over stdio.
Targets and delivery:
list_targets,send_event,get_event,replay_event,get_usageAgent mailbox:
list_mailboxes,list_unread,get_message,claim_message,ack_message
The server never accepts a destination URL. send_event requires a registered target ID returned by list_targets.
MCP-originated items use the same $0.10 per 1,000 accepted-item price as the application API. Each newly accepted webhook event, mailbox message, or A2A handoff is billed once. Retries, reads, claims, acknowledgements, replays, rejected requests, and idempotent duplicates are free.
Mailbox consumers follow one bounded lifecycle: list unread messages, claim one for a five-minute lease, process it, then acknowledge it with the same API key.
Run
Requires Node.js 20 or later and a PromptJang API key.
