## What It Does

AgentBase is an open registry of agent instruction files: system prompts, skills, workflows, domain packs, safety filters, and orchestration patterns. This MCP server wraps the registry's HTTP endpoints and exposes them as structured MCP tools.

## Tools

| Tool | Description |
|------|-------------|
| `search_registry` | Search instruction files by keyword, domain, or type |
| `get_file` | Retrieve a specific instruction file by ID |
| `list_categories` | List all available categories and domains |
| `get_featured` | Get featured/top-rated instruction files |

## Install

```json
{
  "mcpServers": {
    "agentbase": {
      "command": "npx",
      "args": ["-y", "@agentbase1/mcp-server"]
    }
  }
}
```

## Use Cases

- AI agents that need to load domain-specific instructions at runtime
- Claude Code workflows that pull skills from a shared registry
- Teams sharing system prompts and workflows across agents
- Safety filter retrieval for production AI deployments
