Tools & capabilities
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.
Replicate tools 16
list_modelsList all public models available on Replicate, paginated via cursor; returns owner, name, description, run count, and latest version id for each model.modelFetch metadata for a specific Replicate model by owner and name, including description, visibility, run count, latest version, and GitHub URL.model_versionsList all published versions of a Replicate model by owner and name; returns version ids, creation timestamps, and input/output schema for each version.model_versionFetch full metadata for a specific Replicate model version by owner, name, and version_id, including the complete input/output OpenAPI schema and Cog version.search_modelsSearch public Replicate models by keyword query; returns matching models with owner, name, description, and run count.collectionsList all curated Replicate model collections (e.g. "text-to-image", "speech-to-text"); returns collection slug, name, and description.collectionFetch models belonging to a specific Replicate collection by slug (e.g. "text-to-image"); returns the collection description and a list of model objects.create_predictionStart a Replicate model run by submitting a version id and input object; returns a prediction id and status that can be polled with the prediction tool until output is ready.predictionPoll the status and retrieve output for a Replicate prediction by id; returns status (starting/processing/succeeded/failed/canceled), output URLs, and logs.list_predictionsList your recent Replicate predictions in reverse chronological order, paginated via cursor; returns prediction id, model version, status, and creation timestamp.cancel_predictionCancel a prediction.list_deploymentsList your Replicate model deployments (dedicated, auto-scaled endpoints), paginated via cursor; returns owner, name, current model version, and scaling config.- +4 more on the listing page
