Flux AI & MCP
On this page
Flux AI is the shared AI layer of the FluxWP packages. OpenRouter and Anthropic keys, the model catalogue and prices, prompt caching, a tool registry, usage logs, billing and spending limits live here once; Flux Chat, Flux Mail, Flux Social, Flux Lang, Flux Studio and the rest call it instead of talking to AI providers themselves. Authorised users also get a streaming AI chat in the admin that can use those tools.
Features
Hub for other plugins
flxai_chat() / flxai_complete() with tools, streaming, prompt caching (Claude) and model fallback; flxai_ready(), flxai_model_for(), flxai_budget_status().
Connected systems: each plugin with status, model, 30-day requests, tokens, cost, errors and last use; on/off per system; per-plugin model in Settings.
Tools: every tool registered through flxai_tools or Flux SEO, with source, reads/writes, approval flag, capability, 30-day calls and average time; on/off per tool.
Images in answers: widget /mermaid blocks rendered to PNG through Gotenberg or Imagick.
Image and video generation for Flux Studio through fal.ai, EvoLink, OpenAI, Gemini and OpenRouter (flxai_media_submit).
Costs and limits
Overview: daily, weekly and monthly spend against limits, cost, requests, tokens (input, output, from cache), total time split into model vs tools, errors; daily charts for 7 to 180 days, per plugin.
Billing: month by month with cache savings, per provider, per plugin and per model, CSV download.
Logs: every model request and tool call (where, who, model or tool, tokens, cache, duration, cost); content stored masked (e-mail, phone, IBAN, keys) and kept 30 days by default.
Spending limit action: block or only warn, with a warning percentage.
Shared chat
The AI button in the admin opens a docked or floating chat with chat history, search, model picker, suggestions for the current page and streaming answers.
Changes need the user’s approval in the chat; stop at any time; edit a message or go back to an earlier point.
The chat keeps running across page loads.
