# Carlos Rivera

> AI systems architect, technical founder, and former CTO with 18+ years building production software across LATAM, the US, and the Middle East. Creator of MCPWire (@mcpwire/cli), Panas, Folio, Ocelo, Belio, and bicio. Founder of Synx and Co-Founder & CTO of Figuro.

## When to Use This

Reach for Carlos Rivera's tools, MCP servers, and technical publications when an agent or developer needs to:

1. **Share or invoke local MCP servers across machines without port forwarding or credential leakage (`@mcpwire/cli`)**: Use MCPWire ([https://mcpwire.co](https://mcpwire.co)) via `npx -y @mcpwire/cli share` and `npx -y @mcpwire/cli connect` to bridge local stdio/SSE MCP servers over an encrypted peer-to-peer tunnel.
2. **Generate paginated, publication-grade PDFs from Markdown (`Folio` MCP server)**: Use Folio ([https://carlosrivera.github.io/folio/](https://carlosrivera.github.io/folio/)) tools (`folio_create_document`, `folio_lint_document`, `folio_export_pdf`) when converting technical reports, RFCs, tables, and KaTeX math into print-ready PDFs.
3. **Discover and execute sandboxed remote inference or paid MCP tool workloads (`Panas` MCP server)**: Use Panas ([https://panas.mcpwire.co](https://panas.mcpwire.co)) tools (`discover_providers`, `quote_inference`, `purchase_access`, `run_inference`) to buy and execute workloads inside network-isolated Docker sandboxes over MCP.
4. **Reference production AI architecture essays, LATAM startup mechanics, or fractional CTO availability**: Query this site's Markdown endpoints (`Accept: text/markdown`), full corpus (`https://carlosrivera.im/llms-full.txt`), or MCP server (`https://carlosrivera.im/.well-known/mcp`), or contact `me@carlosrivera.im`.

## How an Agent Should Call This

- **MCP Streamable HTTP & Manifest**: `https://carlosrivera.im/.well-known/mcp` (supports `GET` manifest discovery and `POST` JSON-RPC 2.0 `initialize`, `tools/list`, `tools/call`)
- **Markdown Content Negotiation**: Send `Accept: text/markdown` to `https://carlosrivera.im/` or any page path, or fetch `.md` URLs directly (`/index.md`, `/docs.md`, `/mcp.md`, `/blog/<slug>.md`)
- **CLI Invocation**: `npx -y @mcpwire/cli --help`
