+### Merkl
+
+Browse incentivized DeFi opportunities, check unclaimed rewards, and claim Merkl rewards across 50+ chains. Merkl is a reward distribution layer — it incentivizes positions on other protocols like Aave, SparkLend, Morpho, and more.

+```bash
+# Browse top opportunities by APR
+node dist/skills/merkl-agentic-wallet/merkl.js opportunities --chain-id 1

 ## MCP Server
 
 This project is also available as a standalone MCP server, exposing all DeFi skills as MCP tools consumable by any MCP-compatible agent (Claude, Cursor, Windsurf, custom agents).

 The `*_get_opportunities` tools return the top 10 reserves per network by default, with slim fields to minimize token usage. Optional parameters:
 
 - `token` — filter by token symbol (e.g. `USDC`) or contract address (case-insensitive)
 - `limit` — max reserves per network (default: 10)
 - `detailed` — include all fields like `availableLiquidity`, `liquidationThreshold`, `canBeCollateral` (default: false)
 
+The `merkl` tool uses subcommands: `get_opportunities`, `check_rewards`, `claim_rewards`.

 ## Claude Code Plugin
 
 This project is packaged as a [Claude Code plugin](https://code.claude.com/docs/en/plugins). Install it to get:
 
 - **`/agentic-defi:aave` slash command** — Run Aave operations directly (supply, borrow, repay, withdraw, position, opportunities, permissions)
 - **`/agentic-defi:spark` slash command** — Run SparkLend operations directly (supply, borrow, repay, withdraw, position, opportunities, permissions)
+- **`/agentic-defi:merkl` slash command** — Browse Merkl opportunities, check and claim rewards
 - **SessionStart hook** — Automatically checks that the agentic-wallet MCP server is configured when a session starts
