What changed

Adds Cloudflare Workers AI as a model provider for Dify — serverless inference over Cloudflare's open-model catalog (Llama 3.3 70B FP8, Llama 3.1 8B, Llama 4 Scout 17B, Qwen 2.5 Coder 32B, DeepSeek R1 Distill Qwen 32B) with a generous free tier.

• OpenAI-compatible endpoint (/client/v4/accounts/{account_id}/ai/v1) — full chat, streaming, and tool calls verified
• Dedicated Account ID credential field — no manual endpoint URL or raw model IDs (unlike the generic OpenAI-compatible provider)
• Pre-filled model catalog with pricing
• Tested live on Dify Community Edition: 5/5 models respond, tool calls flow through the agent pipeline correctly

Risk level

• Low risk
• Medium risk
• High risk

Required checks

• I have read and followed the Marketplace submission requirements.
• I have read and comply with the Plugin Developer Agreement.
• I tested this plugin on Dify Community Edition and Dify Cloud, or documented any limitation below.
• The package contains only files needed at runtime.
• The package does not contain secrets, local credentials, .env files, .git directories, virtual environments, caches, logs, or IDE files.
• The package does not contain executables or bundled binaries, or I explained why they are required below.
• The plugin README includes setup steps, usage instructions, required APIs or credentials, connection requirements, and the source repository link.
• The plugin includes PRIVACY.md or a hosted privacy policy, and manifest.yaml references it.
• All user-facing text is primarily in English, with any localized README files following the i18n guidance.

Testing notes

• Tested on Dify Community Edition (Docker) with FORCE_VERIFYING_SIGNATURE=false for the unsigned community package.
• Verified: Llama 3.3 70B FP8, Infire Llama 3.1 8B, Llama 4 Scout, Qwen 2.5 Coder 32B, DeepSeek R1 Distill — all respond correctly; Llama 3.3 tool calls reach Dify's agent pipeline (finish_reason: tool_calls).
• Note: @cf/meta/llama-3.1-8b-instruct is deprecated upstream (2026-05) — replaced with @cf/meta/infire-llama-3.1-8b-instruct.

Security and privacy notes

None. This plugin only sends chat completion requests to the Cloudflare Workers AI API using the account's own API token (CLOUDFLARE_API_TOKEN + CLOUDFLARE_ACCOUNT_ID). It does not execute code, access local files, or fetch arbitrary URLs. See PRIVACY.md for the privacy policy.

Local validation

• uv run pytest — 2 tests passed (endpoint URL construction, Account ID requirement)
• Installed the .difypkg on Dify Community Edition (Docker, FORCE_VERIFYING_SIGNATURE=false) — provider listed as Ready
• All 5 models responded live: @cf/meta/llama-3.3-70b-instruct-fp8-fast, @cf/meta/infire-llama-3.1-8b-instruct, @cf/meta/llama-4-scout-17b-16e-instruct, @cf/qwen/qwen2.5-coder-32b-instruct, @cf/deepseek-ai/deepseek-r1-distill-qwen-32b
• Tool calls verified: Llama 3.3 70B and Llama 4 Scout returned finish_reason: tool_calls (code interpreter), and Dify's agent_thought displayed the executed tool result

Updated the PR to match the current marketplace validator: it now contains exactly one file — puspoaditya/cloudflare_workers_ai.difypkg (the validator requires a single .difypkg change per PR; source, README, and privacy policy are all inside the package).

The pre-check runs are waiting for approval (action_required) — could you approve them so the checks can run? Thanks!

[puspoaditya]

Fixed all pre-check findings: manifest now includes privacy, repo, contact (and recommended meta.minimum_dify_version); PR body now has the required Security and privacy notes and Local validation sections; the .difypkg was rebuilt and re-uploaded. Could you approve the re-run? Thanks!
