Connects Corenexis cloud utilities to your AI agent for PDF rendering, OCR, barcode generation, and mailbox verification.
claude mcp add --transport http corenexis-api https://api.corenexis.com/mcp/serverWhat CoreNexis API does
This remote HTTP server connects directly to https://api.corenexis.com/mcp/server. It exposes endpoints that transform Markdown or HTML into PDF files using a browser rendering engine. It also extracts text from scans or receipts through OCR.
Other bundled tools handle image compression, image hosting on a CDN, and barcode creation covering formats like QR, Code128, and EAN-13. Multi-page PDF text extraction runs as an asynchronous background job with separate status checks.
You must provide an account API key inside the x-api-key header before sending commands. Tool invocations draw against your personal plan quota, so missing API subscriptions will block execution immediately.
