Overview

AI-generated overview

A remote MCP server offering paid, per-call crypto and financial data: transaction explanations, DeFi yields, token safety, SEC filings and OFAC screening.

What you can do
Checkpoint402 exposes six tools over a remote HTTP endpoint. A free list_services tool shows each data service with its price and inputs. Paid tools explain Base or Ethereum transactions in plain English, list top DeFi yields across many pools with risk tiers, score newly launched token pools with red flags, summarize recent SEC 8-K filings with plain-English item codes, and screen names or wallet addresses against the OFAC sanctions list.
When to use it
Useful when an assistant needs on-demand blockchain or financial-regulatory context: decoding a transaction, comparing DeFi yields, checking a new token for honeypot or liquidity risks, tracking company events from SEC filings, or screening a counterparty or wallet for sanctions.
Requirements
A remote MCP client connecting to the hosted endpoint; no local runtime, packages, accounts or API keys are declared. Paid tools require payment of USDC on Base via x402 per successful call; the free list_services tool needs no payment. Network access to the provider is required.
Before you install
Five of six tools charge per successful call in USDC on Base (from $0.03 to $0.10), so usage spends real money; errors are stated not to be charged. Queries, including names and wallet addresses sent for sanctions screening, go to a third party, and results draw on external data sources (DefiLlama, GeckoTerminal, SEC, OFAC) that may be delayed or incomplete. Treat outputs as informational, not financial or compliance advice.

Installation

In SourceWeft

  1. Open Checkpoint402 in the dashboard and add it to a workspace.
  2. 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/com.checkpoint402%2Fcheckpoint402/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
