Cloudflare Workers AI MCP tools 4
list_modelsList the Cloudflare Workers AI models supported by this server. Use this tool to discover available model ids before calling chat_completion, embed_text, or generate_image — it returns the complete catalog of chat models, embedding models, and image models with their roles. This tool does not call the Cloudflare API and works without credentials.chat_completionRun an LLM chat completion using Cloudflare Workers AI. Use this tool when you need direct LLM inference with an explicit message list (system/user/assistant roles) — for example summarization, translation, Q&A, classification, or code generation. The request is sent to the Workers AI OpenAI-compatible endpoint and the full assistant reply is returned as a single text block together with the model id and finish reason. No streaming is performed. Requires CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN environment variables; costs are billed to your Cloudflare account (free tier available).embed_textGenerate numerical vector embeddings for one or more text inputs using Cloudflare Workers AI. Use this tool when you need semantic vector representations of text — for example similarity search, clustering, deduplication, or retrieval-augmented generation. Returns one embedding array (384-dimensional for BGE small, 768 for BGE base) per input text, in the same order as the inputs. Embeddings are generated by the native Workers AI endpoint and are deterministic for identical inputs. Requires CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN environment variables.generate_imageGenerate an image from a text prompt using Cloudflare Workers AI (Flux 1 Schnell). Use this tool when the user asks for a picture, illustration, concept art, or visual asset — e.g. logos, scene descriptions, thumbnails, or design mockups. The image is generated by the Flux 1 Schnell model on Workers AI and returned as a base64-encoded string; decode it to obtain the image file (PNG or JPEG depending on the model output). Generation is asynchronous and typically takes a few seconds. Note: Cloudflare applies content moderation — prompts containing NSFW content are rejected with an error. Requires CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN environment variables.
