# Cursor

> What init writes for Cursor, and how hooks, MCP, and rules fit together.

`stacktaste init` or `stacktaste agents add cursor` writes three things under `.cursor/`.

## Files

| File | Role |
| --- | --- |
| `.cursor/mcp.json` | Starts `stacktaste mcp` on stdio |
| `.cursor/hooks.json` | sessionStart, beforeSubmitPrompt, afterFileEdit, stop, preToolUse |
| `.cursor/rules/stacktaste.mdc` | Always-apply ranked taste. Regenerated on pull, sync, and review |

## Hooks

| Event | Output |
| --- | --- |
| `sessionStart`, `beforeSubmitPrompt`, `afterFileEdit` | Ranked `additional_context` |
| `stop` | Harvests “do not use X” into a proposed item |
| `preToolUse` | `allow`, or `deny` when a blocking policy needle matches |

Hooks stay quiet. JSON on stdout only.

## MCP

See [MCP overview](/mcp/overview). Cursor calls `taste_context` when it needs an explicit slice.

## Dashboard

`/app/agents` → Cursor tab is live. Other tabs say Coming soon.
