Server-provided instructions

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

eurc402 provides EURC-priced, EU-sovereign compliance data for agents. `validate_eu_vat` is FREE (official VIES, all 27 EU member states). `lookup_eu_company` detects a company's jurisdiction for free and returns how to fetch the FULL normalized record (name, status, legal form + ELF code, address, officers across 10 EU registers) via the paid x402 endpoint — payable per call in EURC or USDC on Base, no signup.

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 eurc402-mcp https://eurc402.com/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 eurc402-mcp --url https://eurc402.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable eurc402-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "eurc402-mcp": {
      "url": "https://eurc402.com/mcp"
    }
  }

Cline

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

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 eurc402-mcp https://eurc402.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
