Light MCP Plugin for Claude Code

A Claude Code plugin marketplace that connects Claude Code to Light's financial platform via MCP.

Once installed, Claude Code can query your bills, vendors, cards, expenses, ledger accounts, and more — directly from your terminal.

Full setup guide: Connect your AI assistant to Light

Prerequisites

• A Light account with MCP enabled (see Connect your AI assistant to Light)
• Claude Code installed

Setup

1. Generate a Light MCP token

1. Open Settings > Profile in Light
2. Scroll to MCP Tokens
3. Click Add, enter a name (e.g. Claude Code), and click Create
4. Copy the token (starts with lmcp_) — it won't be shown again

2. Set the token as an environment variable

Add this to your shell profile (~/.zshrc, ~/.bashrc, etc.):

export LIGHT_MCP_TOKEN="lmcp_paste_your_token_here"

Then reload your shell:

source ~/.zshrc  # or ~/.bashrc

3. Install the plugin

In Claude Code, run:

/plugin marketplace add light-space/light-mcp
/plugin install light-mcp@light-mcp

Restart Claude Code. Light tools will appear in the tool list.

Verify

Ask Claude Code:

"What Light tools do you have available?"

If the connection is working, it will list the available Light tools.
