Crypto Link Check MCP

An MCP server that checks crypto links for phishing lookalikes of wallets, exchanges, and dapps by comparing against a curated list of official domains to flag typosquats, punycode, and suspicious patterns.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Check crypto links for phishing before connecting a wallet. Read-only; never asks for keys.

Tools

2 advertised

check_crypto_link

Advertised by the server during the last successful anonymous check.

Advertised read-only

Free, read-only, no network fetch: before connecting a wallet or signing, check a URL/domain for crypto phishing signs (lookalike or typosquat of ~60 wallets/exchanges/dapps, punycode, free hosting, bait words). Returns verdict official | no_red_flags | caution | suspicious | dangerous, plus a link to the paid full check (0.005 USDC via x402: domain age, DNS, redirects, page scan for seed-phrase prompts).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http crypto-link-check-mcp-workers https://crypto-link-check.nextill-pos.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add crypto-link-check-mcp-workers --url https://crypto-link-check.nextill-pos.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable crypto-link-check-mcp-workers in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "crypto-link-check-mcp-workers": {
      "url": "https://crypto-link-check.nextill-pos.workers.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "crypto-link-check-mcp-workers": {
      "type": "streamableHttp",
      "url": "https://crypto-link-check.nextill-pos.workers.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start crypto-link-check-mcp-workers and inspect its tools.

VS Code configuration

{
  "servers": {
    "crypto-link-check-mcp-workers": {
      "type": "http",
      "url": "https://crypto-link-check.nextill-pos.workers.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http crypto-link-check-mcp-workers https://crypto-link-check.nextill-pos.workers.dev/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "crypto-link-check-mcp-workers": {
      "url": "https://crypto-link-check.nextill-pos.workers.dev/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "crypto-link-check-mcp-workers": {
      "serverUrl": "https://crypto-link-check.nextill-pos.workers.dev/mcp"
    }
  }
}
