io.github.userdefault13/cron402-mcpv1.1.1Calendar & Time

Schedule webhook calls, pay per run in USDC on Base via x402. Ten tools, built for small models.

The current version, v1.1.1, was published to the official MCP registry on 2026-09-07. It is distributed as cron402-mcp on npm, filed under Calendar & Time by this index, and declares 4 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

In-path gate · all MCP tools

Using cron402 in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Trust verdict · v1 advisory · method
NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

That verdict was true at screening time (snapshot 2026-09-08).

Contracts can change after screening, with no version bump. The gate pins cron402’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Environment variables
CRON402_PRIVATE_KEY
secret

Agent wallet private key (0x…). Fund with USDC on Base mainnet or Sepolia. Without it the server starts read-only: the free tools still work.

CRON402_NETWORK

CAIP-2 network id. Default eip155:8453 (Base mainnet); use eip155:84532 for Sepolia.

CRON402_API_URL

cron402 API base URL. Defaults to the production Worker.

CRON402_STATE_DIR

Directory where created job ids are remembered so list_crons can recover them. Defaults to ~/.cron402.
