Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account Dyln01 for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

ChronoKey is a hosted, pay-per-call MCP server offering utility tools: timestamps, UUIDs, gas prices, domain WHOIS/DNS/SSL lookup, text extraction and keyed or,

What you can do: Get current time in a chosen timezone and generate batches of v4 or v7 UUIDs, with a free health check and a limited daily free tier for these two tools. Extract structured entities from unstructured text, including deep mode, verified extraction with confirmation, and variants that fetch the first URL found or return a grouped summary. Look up real-time EIP-1559 gas prices across several chains and get combined WHOIS, DNS and SSL certificate data for a domain. Store, recall and full-text search values under namespaced keys with optional TTL. Subscribe to a Pro plan and check the subscription status bound to the current session.
When to use it: Useful when an assistant needs small, common utilities on many runs — timestamps, UUIDs, entity extraction, domain intelligence, blockchain gas prices or simple persistent memory — without hosting anything locally, and when per-call micropayments or a small monthly subscription are acceptable.
Requirements: Remote Streamable HTTP endpoint; no local runtime, account or API key declared. Requests need the Accept header for JSON and event-stream and a JSON content type. Paid tools require x402 payment (USDC on Base, Polygon or Arbitrum) or MPP (pathUSD on Tempo); a Pro subscription costs $5 for 30 days. Network access required.

Before you install

Most tools cost money per call, and the subscribe tool charges $5 for 30 days; payment is settled through crypto payment protocols, so a wallet and signed payment authorizations are involved. The free tier covers only 10 calls per day per session for timestamp and uuid. Memory tools write and store data on a third-party hosted service, and extraction tools send your text to that service. Pro benefits are tied to the same MCP session.

Installation

In SourceWeft

Open ChronoKey in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Dyln01%2Fchronokey/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

What This Is

ChronoKey is a hosted MCP server that provides 15 utility tools AI agents need on nearly every run. Payment is handled via the x402 protocol (USDC on Base, Polygon, or Arbitrum) or MPP (pathUSD on Tempo). Any MCP-compatible client can connect and call the tools.

Endpoint

Transport: Streamable HTTP
Method: POST
Required header: Accept: application/json, text/event-stream
Content-Type: application/json

Pricing: First 10 calls per day per session free, then Pro subscription, then $0.001 USD.

uuid

Generates 1-100 UUIDs.

Input: { "count": 5, "version": "v7" }

count (optional): 1-100, defaults to 1
version (optional): "v4" (random) or "v7" (time-ordered), defaults to "v4"

Pricing: First 10 calls per day per session free, then Pro subscription, then $0.001 USD.
