Unl

Unl is the product by Unlimitless (unlimitless.ai).

Unl, your why agent. The infra agent for your fleet.

Your other agents do the work; Unl makes sure they work from what you decided, and why. Connect it once to Claude, ChatGPT, Cursor, Claude Code or any MCP client, and each agent is served the decisions that bear on its task, with the reason each was made, before it acts. Free to start.

Connect

One URL, every surface.

https://api.unlimitless.ai/mcp

Add it wherever your tool takes an MCP server. You'll be asked to sign in; that sign-in is the connection. Nothing to pay at the door, and no API key to paste.

Claude Code

As a plugin, from this repo's marketplace:

/plugin install unl --marketplace neilmortimer-kar/unl-connector

Or as a plain MCP server:

claude mcp add --transport http unl https://api.unlimitless.ai/mcp

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per project):

{ "mcpServers": { "unl": { "url": "https://api.unlimitless.ai/mcp" } } }

Anything else

Any client that speaks MCP over streamable HTTP works with the same URL.

What this repo is

Unl's manifests and listing packaging. Not the product.

path	what it is
`server.json`	MCP Registry entry
`plugin.json`, `mcp.json`	the Agent Plugins 1.0 package (one folder, every host that reads the open format)
`skills/unl/SKILL.md`	the Unl agent itself, its jobs and rules, as an Agent Skill
`.mcp.json`	server config for the Claude and Cursor manifests
`.claude-plugin/plugin.json`	Claude plugin manifest
`.claude-plugin/marketplace.json`	self-hosted Claude Code marketplace
`.cursor-plugin/plugin.json`	Cursor plugin manifest
`assets/logo.png`	the Unl mark

Unl's behaviour is served from the connection, not shipped here, so it's the same on every surface, and it improves without you reinstalling anything. The skill only tells the host's own model how to work as Unl, so the agent runs on the AI you already use.

Unlimitless-Inc/unl, the main repository
@unlimitless/ai-sdk on npm

Trust

Nothing is written without your word.
Your reasoning stays yours. Unl holds what you give it and never reaches into your model, your files, or your other tools.
Disconnect whenever you like, from the portal.
