Flux (AO & Arweave)
Enables developers to run, create, and test AO (Arweave's compute layer) code using natural language commands without needing deep technical knowledge of the underlying systems.
Integrates with Arweave and AO ecosystems to enable developers to run, create, and test AO code and blueprints using natural language commands without requiring deep technical knowledge of the underlying systems.
What it does
- Run AO code with natural language commands
- Create custom AO blueprints using plain English
- Test AO processes and handlers automatically
- Generate complex AO handlers from descriptions
- Integrate with existing AI development tools

About Flux (AO & Arweave)
Flux (AO & Arweave) is a community-built MCP server published by asrvd that provides AI assistants with tools and capabilities via the Model Context Protocol. Flux (AO & Arweave) lets developers easily run, create, and test AO code using natural language—no deep technical skills It is categorized under developer tools.
How to install
You can install Flux (AO & Arweave) in your AI client of choice. Use the install panel on this page to get one-click setup for Cursor, Claude Desktop, VS Code, and other MCP-compatible clients. This server supports remote connections over HTTP, so no local installation is required.
License
Flux (AO & Arweave) is released under the MIT license. This is a permissive open-source license, meaning you can freely use, modify, and distribute the software.

Features Implemented
- Run AO code using just natural language
- Create and run custom AO code/blueprints completely using natural language
- Integrates with your existing AI dev tools like Cursor, Windsurf, Claude, and anything that supports MCP tool calling
- Can test out all the code it pushes to an process
- Can create and test complex handlers
Features to be implemented
- Inetgration with AO ecosystem tools
- Better code generation capabilities by adding more context about AO
Tech stack
- AO
- Arweave
- MCP typescript sdk
- Typescript
- Node.js
Installation
There are currently two ways to install and use Flux, right now it has been tested significantly only on Cursor so we will be showing how to install FLux in Cursor -
-
Local Setup - For users who want everything to be present locally, no remote servers involved
- Make sure you have latest stable version of NODE.js installed - Node.js download
- Open Cursor and go to Settings > Cursor Settings > MCP > Add new MCP tool
- Paste this code in the file
"mcpServers": { "flux": { "command": "npx", "args": ["-y", "flux-ao@latest"], } } - if you did everything correctly you will be able to see the flux MCP loaded with all the tools, and its ready to be used in Cursor (PS: You might have to reload the MCP multiple times or restart Cursor)!

-
Remote Setup - For users who want to use Flux without installing anything locally
- Open Cursor and go to Settings > Cursor Settings > MCP > Add new MCP tool
- Paste this code in the file
"mcpServers": { "flux": { "url": "https://flux-2esw.onrender.com/sse", } } - if you did everything correctly you will be able to see the flux MCP loaded with all the tools, and its ready to be used in Cursor (PS: You might have to reload the MCP multiple times or restart Cursor)!

Usage
We would suggest you add the llms.txt for AO docs in cursor first and use it as a context before you start using the MCP server. If you don't know how to do it, checkoout this documentation on how to add docs to cursor.
The more context you give to cursor, the more acurate the responses will be.
Now add these custom rules in your Cursor project to make sure Cursor doesn't hallucinate or give wrong responses. You can add these rules in the Settings > Cursor Settings > Rules > Add new rule.
For adding json capabilities ONLY IF NEEDED, you need to add a line "local json = require("json")" on top of file. BUT DONT USE IT UNLESS NEEDED. SIMPLE THINGS CAN BE DONE USING AO PROCESS STATE
Always use Send instead of msg.reply
Always make sure a handler is sending out a response/reply (using Send) and send it as data as well instaed of just returning using tags
Never add any tags by yourself, always add tags when needed or instructed by user, also {"Action":"Eval"} tag is for running lua in an ao process and {"Action" : "action_name"} is for running a handler
Never add the "Type" tag to anything, thats reserved for internal ao specifications
Always use Handler.utils whever possible when creating a handler, for example --
Handlers.add(
"pingpong",
Handlers.utils.hasMatchingTag("Action", "Ping"),
function (msg)
Handlers.utils.reply("Pong")(msg) -- or use Send() here
end
)
Now you can start using the Flux MCP server in Cursor Agents.
