Tools (Knowledge)
Tools are a Knowledge citizen — not a fifth nav pillar.
They are DataObjects (schema:tool / schema:tool_pack) aligned with the MCP Tool shape: name, description, inputSchema, optional annotations — plus Closure outputSchema (required for internal tools) and policy (permission, risk, pack). Execution stays in code registries or MCP tools/call.
In Closure
Knowledge → Tools — packs (left) · tools (center) · properties (right, including inputSchema).
| Pack | Purpose |
|---|---|
| Closure Agent | Default hosted agent tools |
| Platform build | Governed build-program tools |
| Closure MCP | IDE platform_* tools |
| Research | Web / Wikipedia / DuckDuckGo / HTTP fetch |
| Figma MCP (etc.) | Connected via Integrations → Tools |
Adding packs via Integrations
Connect Figma MCP or MCP Tool Packs under Integrations. On save, Closure discovers tools (tools/list or fixture) and the pack appears under Knowledge → Tools.
Workflow agent nodes bind tools with allowedTools (tool id strings). Empty allowlist = agent pack defaults — not the full platform build suite.
