Cursor

Cursor is Full tier. The Bash installer writes HTTP MCP, shared capture hooks, the skill suite, and a local Cursor plugin. Native PowerShell writes the MCP entry and installs skills. It does not stage the plugin or install shared hooks. Automatic recall injection is off. Set MEMORY_CRYSTAL_INJECT_RECALL to 1 or true to turn it on. Capture still runs when the Bash installer writes hooks.

Agent Instructions

Install Memory Crystal for Cursor. Run the Bash installer so MCP, hooks, skills, and the local plugin are all written. PowerShell configures MCP and skills. Follow the auth and backend prompts. Then run Developer: Reload Window and confirm memory-crystal is connected. Recall is a tool call unless MEMORY_CRYSTAL_INJECT_RECALL=true.

macOS/Linux/WSL:
curl -fsSL https://memorycrystal.ai/crystal | bash -s -- --targets cursor

Windows PowerShell (MCP and skills):
iwr https://memorycrystal.ai/install.ps1 -OutFile install.ps1; .\install.ps1 -Targets cursor

curl -fsSL https://memorycrystal.ai/crystal | bash -s -- --targets cursor

iwr https://memorycrystal.ai/install.ps1 -OutFile install.ps1
.\install.ps1 -Targets cursor

Add --backend local or -Backend local for local data storage. See Local-First Setup.

What the Bash installer writes

Piece	Path
HTTP MCP server `memory-crystal` with bearer header	`~/.cursor/mcp.json`
Shared capture hooks (`--host cursor`)	`~/.cursor/hooks.json`
Skill suite	`~/.cursor/skills`
Local plugin (MCP manifest, hooks, rules, skills)	`~/.cursor/plugins/local/memory-crystal`

The plugin version staged from this repo is 0.10.1. Cursor has no managed block in an agent instructions file because agentsFile is unset. The Bash hook installation still stages the shared ~/.memory-crystal/instructions.md support file. hooks.shells is bash. Native PowerShell updates mcp.json and skips hooks and plugin staging. Use the Bash installer when you want capture. The MCP entry:

{
  "mcpServers": {
    "memory-crystal": {
      "type": "http",
      "url": "https://api.memorycrystal.ai/mcp",
      "headers": {
        "Authorization": "Bearer your-api-key"
      }
    }
  }
}

A local backend uses http://127.0.0.1:3211/api/mcp with the same header shape.

After install

Reload the window (Developer: Reload Window) so Cursor picks up the plugin, MCP server, skills, and hooks. Confirm the memory-crystal server is connected before relying on tools. Hooks are host-attributed with --host cursor, so captures are not labelled with another host that shares ~/.memory-crystal/config.json.

Uninstall

curl -fsSL https://memorycrystal.ai/uninstall.sh | bash -s -- --targets cursor

That removes the MCP entry, ~/.cursor/hooks.json hook entries, the local plugin directory, and the Crystal skill directories. See Uninstall.
