+# Yield.xyz AgentKit — Base plugin
+
+Discover and manage on-chain yield opportunities across 80+ networks. Find and compare yields, check balances and rewards, and build transactions for staking, lending, vaults, restaking, and liquidity pools.
+
+## What it ships
+
+| Component | Detail |
+|---|---|
+| Skill | `yield-xyz-agentkit` — routing logic, validator selection, transaction ordering, and safety checks |
+| MCP server | `yield-xyz-agentkit` → `https://mcp.yield.xyz/mcp` (Streamable HTTP) |
+
+No commands, agents, hooks, or LSP servers.
+
+## Install
+
+Grok Build:
+
+```bash
+grok plugin install stakekit/agentkit#plugins/yield-xyz-agentkit --trust
+```
+
+Claude Code:
+
+```bash
+/plugin marketplace add stakekit/agentkit
+/plugin install yield-xyz-agentkit@agentkit
+```
+
+## Configuration
+
+The MCP server works without configuration — discovery and diligence tools are open. For authenticated use, supply your own Yield.xyz API key as an `x-api-key` header:
+
+```json
+{
+  "mcpServers": {
+    "yield-xyz-agentkit": {
+      "type": "http",
+      "url": "https://mcp.yield.xyz/mcp",
+      "headers": { "x-api-key": "<your key>" }
+    }
+  }
+}
+```
+
+Get a key at [dashboard.yield.xyz](https://dashboard.yield.xyz).
+
+## Custody
+
+The plugin never holds keys or signs. It constructs **unsigned** transactions that your own wallet signs and broadcasts. `submit_hash` accepts an already-broadcast transaction hash for tracking only.
+
+Yield.xyz is SOC 2 compliant — [trust.yield.xyz](https://trust.yield.xyz).
+
+## Connectors
+
+Signing and execution connectors build on this plugin: `yield-xyz-agentkit-privy`, `yield-xyz-agentkit-moonpay`, and `yield-xyz-agentkit-robinhood`. See [`plugins/README.md`](../README.md).
