Installation

Step 1: Install the binaries

# Via npm (recommended)
npm install -g @standardbeagle/agnt @standardbeagle/lci

# Via pip
pip install agnt lightning-code-index

# Via Go (lci only)
go install github.com/standardbeagle/lci/cmd/lci@latest

Step 2: Register MCP servers

Option A: Via slop-mcp (recommended if available)

mcp__plugin_slop-mcp_slop-mcp__manage_mcps
{ "action": "register", "name": "agnt", "command": "npx", "args": ["-y", "@standardbeagle/agnt", "mcp"], "scope": "user" }
{ "action": "register", "name": "lci", "command": "npx", "args": ["-y", "@standardbeagle/lci", "mcp"], "scope": "user" }

Option B: Add to .mcp.json

{
  "agnt": {
    "command": "npx",
    "args": ["-y", "@standardbeagle/agnt", "mcp"]
  },
  "lci": {
    "command": "npx",
    "args": ["-y", "@standardbeagle/lci", "mcp"]
  }
}

Step 3 (Optional): Install Claude Code plugins

The plugins provide commands, skills, and agents that help you use the MCP tools:

# Install the complete toolkit (recommended)
claude plugin add tools@standardbeagle-tools

# Or install individual plugins
claude plugin add agnt@standardbeagle-tools
claude plugin add lci@standardbeagle-tools
