AAI Gateway: Unified MCP & Skill Management, Shared Across AI Agents, 99% Context Token Savings

---

What Is It

AAI = Agent App Interface

AAI Gateway is the interaction gateway for Agent Apps.

What is an Agent App? An Agent App is a collection of capabilities that an Agent can use. For example:

• An MCP Server is an Agent App — it provides a set of tools
• A Skill package is an Agent App — it provides one or more skills

In AAI Gateway, they are abstracted as Agent Apps under unified management. Import once, and all AI Agents can use them immediately.

What Problems Does It Solve

Context Bloat

Traditional: 10 MCPs × 5 tools = 50 full schemas ≈ 7,500 tokens injected into every conversation.

AAI Gateway: each Agent App needs only fewer than 50 tokens for a summary, with details loaded on demand. 99% token savings.

Finding Tools Is Hard

Traditional: search GitHub → read READMEs → copy JSON configs → debug connections → restart Agent.

AAI Gateway: tell your Agent "use AAI to search for xxx" — auto-searches, installs, ready to use.

"Use AAI to search for a browser automation tool"

→ Search → finds Playwright MCP → Agent summarizes a one-line Agent App summary → install → ready to use, no restart needed

"Use AAI to search for a PPT creation skill"

→ Search → finds PPT Skill → uses skill description as Agent App summary → install → ready to use, no restart needed

Duplicate Config

Configure the same thing in Claude Code, Codex, and OpenCode separately? Import once through AAI Gateway, all Agents share instantly.

Quick Start (30 Seconds)

Claude Code:

claude mcp add --scope user --transport stdio aai-gateway -- npx -y aai-gateway

Codex:

codex mcp add aai-gateway -- npx -y aai-gateway

OpenCode — add to ~/.config/opencode/opencode.json:

{
  "mcp": {
    "aai-gateway": {
      "type": "local",
      "command": ["npx", "-y", "aai-gateway"],
      "enabled": true
    }
  }
}

OpenClaw:

openclaw plugins install openclaw-aai-gateway-plugin

Once installed, just tell your Agent what you want to do.

Built-in Tools

Tool	Description
search:discover	Search and install new tools with natural language
mcp:import	Import an MCP Server as an Agent App
skill:import	Import a Skill package as an Agent App
listAllAaiApps	List all registered Agent Apps
enableApp / disableApp	Enable or disable an Agent App per Agent
removeApp	Remove an Agent App
aai:exec	Execute a specific tool within an Agent App

Each imported Agent App generates an app_<app-id> tool that returns the full operation guide and tool list when called.

Preset Agent Apps (auto-discovered when locally installed)

App ID	Name	Description
claude	Claude Code	AI coding assistant for code editing, analysis, and development
codex	Codex	OpenAI-powered AI coding assistant
opencode	OpenCode	AI development assistant for editing files and running commands

Developers: Get Your Agent App Auto-Discovered

Create an aai.json descriptor and submit it to src/discovery/descriptors/. When a user's local environment meets the discovery.checks conditions, the Agent will auto-discover your Agent App.

{
  "schemaVersion": "2.0",
  "version": "1.0.0",
  "app": {
    "name": { "default": "My App" }
  },
  "discovery": {
    "checks": [
      { "kind": "command", "command": "my-app" }
    ]
  },
  "access": {
    "protocol": "mcp",
    "config": {
      "command": "my-app-mcp",
      "args": ["--stdio"]
    }
  },
  "exposure": {
    "summary": "Use when the user wants to do X."
  }
}

discovery.checks supports three check types: command (command exists), file (file exists), path (directory exists).

Supported protocols: mcp, skill, acp-agent
