Locus Payment Skill

Locus connects AI agents to crypto wallets via MCP. Tools are dynamic — each user gets different tools based on their permission group.

Setup (Agent-Guided)

When the user asks to set up Locus, use payments, or anything payment-related — check if Locus is configured and walk them through setup interactively:

Step 1: Check if mcporter is installed

command -v mcporter || npm i -g mcporter

Step 2: Check if Locus is already configured

mcporter config get locus 2>/dev/null

If configured, skip to Usage. If the user wants to reconfigure, run:

mcporter config remove locus

Step 3: Ask the user for their API key

Tell them:

> You'll need a Locus API key to connect your wallet. Get one at https://app.paywithlocus.com — each key is tied to your wallet and permission group. Paste it here when you're ready.

Wait for the user to provide their key. It should start with locus_. If it doesn't, warn them and confirm before proceeding.

Step 4: Configure mcporter

mcporter config add locus \
  --url "https://mcp.paywithlocus.com/mcp" \
  --header "Authorization=Bearer <API_KEY>" \
  --scope home

Step 5: Verify the connection

mcporter list locus

If tools appear, setup is complete — tell the user they're ready. If it fails, ask them to double-check their API key and try again.

Alternative: Script-based setup

Users can also run the setup script directly from the Clawdbot workspace root:

bash skills/locus/scripts/setup.sh

Usage

Always discover available tools first:

mcporter list locus --schema

This returns all tools the user's permission group allows. Tools vary per user — do not assume which tools exist. Use the schema output to understand parameters.

Call any discovered tool:

mcporter call locus.<tool_name> param1=value1 param2=value2

For array/object parameters:

mcporter call locus.<tool_name> --args '{"key": "value"}'

Email → Payment Flow

1. Scan inbox for payment-related emails (invoices, bills, splits, reimbursements)
2. Identify actionable items with amounts, recipients, and context
3. Summarize findings to user
4. On user approval, execute payments via available tools
5. Always confirm with user before sending any payment

Safety Rules

• Never send payments without explicit user confirmation
• Always show: recipient, token, amount, and memo before executing
• Check available balance before attempting payments
• Double-check recipient addresses — typos mean lost funds
• Confirm large payments (>$100) with extra care
