      summary: MCP endpoint for AI agents (Streamable HTTP)
      description: 'Model Context Protocol endpoint — Streamable HTTP transport, JSON-RPC 2.0 over POST. Exposes the same capabilities as this REST API as 5 MCP tools: validate_iban, batch_validate_iban, lookup_bic, check_compliance, lookup_ch_clearing. Flow: POST an `initialize` request, then `tools/list` and `tools/call` (include the returned Mcp-Session-Id header on follow-up calls). Also available as a stdio server via `npx -y ibanforge-mcp`. This path speaks MCP, not the REST conventions documented elsewhere in this spec.'
