# subagenttools.com — the Tool primitive

> The Tool primitive: the 8 real tools of the Managed Agents agent_toolset_20260401 from tools.md — a smaller, different surface than subagentcode.com's 21-tool Claude Code AgentTool enum.

## API
- GET /api/agent-tools — list all cataloged Managed Agents tools
- GET /api/changes — newest-first change feed (?cursor=&limit=) for polling agents
- POST /mcp — Streamable-HTTP MCP endpoint (initialize / tools/list / tools/call get_agent_tools); server card at /.well-known/mcp/server-card.json

## Grounding
Catalogs the real agent_toolset_20260401 (bash/read/write/edit/glob/grep/web_fetch/web_search) — deliberately NOT conflated with Claude Code's larger built-in tool set.
