Feature & Specification Comparison

Specification	Cloudflare Workers AI MCP puspoaditya Conversational AI	Upfirst Conversational AI
Summary	Cloudflare Workers AI inference for AI agents: LLM chat completions (Llama 3.3 70B, Llama 3.1 8B, Llama 4 Scout, Qwen Coder 32B, DeepSeek R1 Distill), text embeddings (BGE small/base), and image generation (Flux 1 Schnell) — generous free tier, no infrastructure to run. npx -y @puspoaditya/cloudflare-workers-ai-mcp.	Upfirst is an AI receptionist for small businesses. It answers every call, takes messages, books appointments, transfers to the right person, and answers callers' questions about your business. This server puts that receptionist inside your AI client. Pull up the last week of calls, read the transcripts, and see where it fell short — then act on it without switching tabs: rewrite the greeting, add knowledge, create texting and transfer skills, restrict facts to business hours. Edits retrain the receptionist within minutes, so a fix you make in conversation lands on the next call. Account & agents — snapshot the whole account; read and update a receptionist's greeting, tone, speech rate, and call blocking Knowledge — read, add, edit, and delete the entries your receptionist answers from, with optional weekly schedules Skills — create and manage the actions it takes on a call: texting the caller, texting a scheduling link, transferring with fallback destinations Calls — filter and search call history, read AI summaries and captured data, pull full transcripts turn by turn Things to try "Review last week's calls and tell me what my receptionist couldn't answer." "Here's how my business runs — build the greeting, knowledge, and transfer rules to match." "This call went badly. Figure out why and fix the knowledge behind it." Connect over Streamable HTTP at https://mcp.upfirst.ai. Sign-in is OAuth 2.1 — no API keys to copy or store.
