402cron — Claude Code MCP server for scheduled HTTP calls
402cron schedules signed requests to an HTTPS endpoint and retries timeouts or unreachable hosts. An agent can manage scheduled tasks through its MCP server.
claude mcp add --transport http 402cron https://402cron.com/mcpWhat 402cron does
Use 402cron to create scheduled requests to an HTTPS destination. Each delivery carries an HMAC-SHA256 signature, so your receiver can validate it; deliveries are at least once, and the same delivery ID can appear again. Your handler should therefore recognise repeats. Tasks can pause after repeated failures and be resumed with a request.
Management requires a token provided after an x402 purchase, paid in USDC on Base. The MCP tools get_pricing, get_docs and get_service_status work without that token; payment happens separately over HTTP. Destinations must use https://. Cron schedules use UTC and have a one-minute minimum interval. A delivery response must arrive within 2 seconds; timeouts and unreachable hosts are retried, while 4xx and 5xx responses are not.
The repository includes Node.js and Python receiver examples, plus a client example that buys a trial and creates a schedule. Credits count delivery attempts rather than dollars, so failed attempts affect the balance too. That matters when estimating how many deliveries a purchased pack will cover.
What it helps with
- schedule HTTP requests to an HTTPS endpoint
- verify incoming requests with their signatures
- retry delivery after timeouts or an unreachable host
- detect repeated deliveries by delivery ID
- pause and resume tasks after repeated errors
Example prompts for the agent
- Connect the 402cron MCP server and show me the available pricing.
- Create a scheduled task that sends data to my HTTPS endpoint.
- Explain how my receiver should verify a delivery signature and handle duplicates.
