elendirna

AI-friendly knowledge vault — elf CLI + MCP server, distributed as a prebuilt binary via npm (no Rust toolchain required).

Install

# one-off, no install
npx -y elendirna --help

# or install globally (the `elendirna` command)
npm i -g elendirna
elendirna --help

The npm package bundles prebuilt elf binaries for all supported platforms and a thin Node launcher that selects the right one at run time. No postinstall script, and no network access at install or run time.

Supported platforms: linux / macOS / Windows × x64 / arm64. Linux builds target glibc ≥ 2.35 (Ubuntu 22.04 baseline); musl/Alpine is not yet shipped — use cargo install eln-cli there.

MCP server

# print a Claude Desktop / .claude/mcp.json snippet for stdio transport
elendirna serve

When launched through this npm wrapper, the snippet's command is the stable elendirna (on PATH after a global install) rather than a node_modules path. For an npx-only setup, use:

{ "mcpServers": { "elendirna": {
  "command": "npx",
  "args": ["-y", "elendirna", "serve", "--mcp", "--transport", "stdio", "--vault", "/path/to/vault"]
} } }
