AAI Gateway MCP Server
io.github.gybob/aai-gateway
Unified MCP & Skill management gateway that reduces context tokens by 99% and auto-discovers tools across AI agents.
What is the AAI Gateway MCP server?
AAI Gateway is a unified management gateway for Agent Apps (MCP servers and Skill packages) that abstracts multiple tools under a single interface. It dramatically reduces context token bloat by loading tool summaries on-demand instead of injecting full schemas, and enables agents to auto-discover and install new capabilities without manual configuration or restarts.
AAI Gateway solves three core problems: context bloat (99% token savings by using summaries instead of full schemas), tool discovery (agents can search for and auto-install tools via natural language), and configuration duplication (import once, share across all AI agents). It works with Claude Code, Codex, OpenCode, and OpenClaw.
How to install AAI Gateway
Copy-paste configuration for popular MCP clients.

Use cases
- Search for and auto-install new MCP servers or skill packages using natural language without manual configuration
- Reduce context token usage by 99% by loading tool summaries on-demand instead of injecting full schemas into every conversation
- Share imported tools and configurations across multiple AI agents (Claude Code, Codex, OpenCode) without duplicating setup
- Enable agents to discover and use locally-installed Agent Apps (Claude Code, Codex, OpenCode) automatically
- Execute specific tools within imported Agent Apps through a unified interface
AAI Gateway MCP server FAQ
AAI Gateway is a unified management gateway for Agent Apps (MCP servers and Skill packages). It abstracts multiple tools under a single interface, reduces context token bloat by 99%, and enables agents to auto-discover and install new capabilities without manual configuration.
AAI Gateway reduces context tokens by approximately 99% compared to traditional approaches. Instead of injecting 50+ full tool schemas (≈7,500 tokens), each Agent App needs fewer than 50 tokens for a summary, with details loaded on demand.
Run: `claude mcp add --scope user --transport stdio aai-gateway -- npx -y aai-gateway`
Run: `codex mcp add aai-gateway -- npx -y aai-gateway`
Yes, AAI Gateway is open-source and free to use. It's available on npm as `aai-gateway`.
Yes. Create an `aai.json` descriptor file and submit a PR to `src/discovery/descriptors/`. Your Agent App will be auto-discovered when users' local environments meet the specified conditions.

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 plugins install openclaw-aai-gateway-plugin
Once installed, just tell your Agent what you want to do.
Built-in Tools

Architecture

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
