ledgermem-cursor-rules

Drop-in Cursor IDE rules + MCP server preset that wire LedgerMem into your AI coding workflow.

Result: Cursor automatically recalls relevant project memory before generating, and saves design decisions back as you make them.

Install

# From your project root
curl -fsSL https://raw.githubusercontent.com/ledgermem/ledgermem-cursor-rules/main/install.sh | bash

What that does:

1. Drops .cursor/rules/ledgermem.mdc into your project
2. Adds an mcpServers entry to ~/.cursor/mcp.json (or creates the file)
3. Verifies npx -y @ledgermem/mcp-server is reachable

Manual install

mkdir -p .cursor/rules
curl -fsSL -o .cursor/rules/ledgermem.mdc https://raw.githubusercontent.com/ledgermem/ledgermem-cursor-rules/main/.cursor/rules/ledgermem.mdc

Then add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "ledgermem": {
      "command": "npx",
      "args": ["-y", "@ledgermem/mcp-server"],
      "env": {
        "LEDGERMEM_API_KEY": "${env:LEDGERMEM_API_KEY}",
        "LEDGERMEM_WORKSPACE_ID": "${env:LEDGERMEM_WORKSPACE_ID}"
      }
    }
  }
}

Then in your shell:

export LEDGERMEM_API_KEY=lm_live_...
export LEDGERMEM_WORKSPACE_ID=ws_...

What's in the rules pack

Rule	When it fires	What it does
Recall before code	Before any non-trivial generation	Calls memory_search for relevant prior decisions
Save decisions	When user accepts an architectural choice	Calls memory_add with the decision + rationale
No repeated questions	When asking the user something	Searches memory first to avoid asking twice
Stack consistency	Before suggesting a library	Checks memory for already-chosen libraries in this project

See .cursor/rules/ledgermem.mdc for the full rule text.

Compatible IDEs

Cursor inherits .cursor/rules/ and MCP config — these also work in:

• Cursor (primary)
• Windsurf (MCP only; uses ~/.codeium/windsurf/mcp_config.json)
• Cline (MCP only; uses ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json)
