Summary
A straightforward CSV parser that handles the messy work of delimiter detection and header inference, then hands you back clean JSON arrays. It runs as a remote service over SSE and uses x402 micropayments, so you're paying per conversion rather than running your own parser. Reach for this when you're building workflows that ingest CSVs from external sources and need consistent JSON output without maintaining parsing logic. The GitHub repo shows TypeScript source but light documentation, so expect to test against your specific CSV formats. Good fit for automation pipelines where you'd rather delegate parsing to an API than bundle a library.

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
{
"mcpServers": {
"csv-to-json": {
"url": "https://csv-to-json.api.klymax402.com/mcp"
