@depegprotocol/mcp-server

Model Context Protocol server for the DEPEG protocol on Solana. Exposes 11 tools that let any MCP-compatible AI agent (Claude Desktop, Cursor, Cline, Continue, Solana Agent Kit-based agents, custom autonomous agents, …) interact with DEPEG: discover pools, query positions, compute pending rewards, swap USDC ↔ stablecoin, stake, claim, unstake, buy boosters, and launch new pools.

DEPEG wraps pump.fun memecoins with a 1:1 USDC-backed stablecoin per coin. Pump.fun trade fees flow into the USDC vault as yield. Holders stake stablecoins for lock-boosted rewards; boosters amplify the multiplier for 7 days.

Install

npm install -g @depegprotocol/mcp-server

Or run on-demand via npx:

npx -y @depegprotocol/mcp-server

Tools

Tool	Purpose	Wallet required?
depeg_find_pool	Look up a pool by coinMint — returns Config + StakingPool + every derived PDA.	No
depeg_list_pools	Enumerate every DEPEG pool on the chosen cluster.	No
depeg_get_user_positions	All StakePositions + UserPoolState for (coinMint, owner).	No
depeg_get_pending_rewards	Client-side pending-reward calc for a specific position. Applies active booster.	No
depeg_swap_usdc_to_stablecoin	Deposit USDC, receive stablecoin 1:1.	Yes
depeg_swap_stablecoin_to_usdc	Burn stablecoin, withdraw USDC 1:1.	Yes
depeg_stake	Stake stablecoin for a LockPeriod (1d, 3d, 7d, 14d, 30d, 90d, 180d, 365d).	Yes
depeg_claim_rewards	Settle + transfer pending rewards on a position.	Yes
depeg_unstake	Withdraw principal + claim, after locked_until.	Yes
depeg_buy_booster	Pay SOL for a 7-day reward multiplier (tier 0..5 → 1.25× / 1.5× / 1.75× / 2× / 2.5× / 3×).	Yes
depeg_launch_pool	Wrap a pump.fun coin as a DEPEG pool (atomic; co-signed by platform admin).	Yes

Read-only tools work without a wallet — you can run the server with just an RPC URL to expose query-only tools to your agent.

Configuration

All via environment variables:

Env var	Default	Purpose
DEPEG_RPC_URL	public mainnet/devnet	Solana RPC endpoint
DEPEG_CLUSTER	mainnet	mainnet or devnet
DEPEG_USDC_MINT	—	Override the USDC mint pubkey
DEPEG_WALLET_SECRET	—	Base58 secret key (write tools require this)
DEPEG_WALLET_PATH	—	Path to a Solana keypair JSON file (alternative)

Add to your MCP host

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "depeg": {
      "command": "npx",
      "args": ["-y", "@depegprotocol/mcp-server"],
      "env": {
        "DEPEG_CLUSTER": "mainnet",
        "DEPEG_RPC_URL": "https://your-rpc-endpoint",
        "DEPEG_WALLET_SECRET": "<base58 secret key>"
      }
    }
  }
}

Cursor / Cline / Continue

Same shape, in each host's MCP server config. The server speaks JSON-RPC over stdio.

Programmatic (TypeScript)

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";

const client = new Client({ name: "my-agent", version: "0.1.0" }, { capabilities: {} });
await client.connect(new StdioClientTransport({
  command: "npx",
  args: ["-y", "@depegprotocol/mcp-server"],
  env: { DEPEG_RPC_URL: process.env.RPC_URL!, DEPEG_WALLET_SECRET: process.env.WALLET_SECRET! },
}));

const pools = await client.callTool({ name: "depeg_list_pools", arguments: {} });

Example agent prompts

Once connected, an agent can drive the protocol with natural-language instructions:

"Find me the DEPEG pool with the highest stake count, then stake 10 stablecoin for 30 days in it."

→ agent calls depeg_list_pools → ranks by totalStakedAmount → calls depeg_stake with lockPeriod: "oneMonth" against the winner.

"Check if my position #1738 has any pending rewards, and if it's more than 0.1 stablecoin, claim it."

→ depeg_get_pending_rewards → conditional depeg_claim_rewards.

"For coin {mint}, deploy a DEPEG pool with vault_bps=4000, staking_bps=4000, and a 5 USDC seed."

→ depeg_launch_pool. (The tx will need PLATFORM_ADMIN co-signature — in production agents should route through depeg.app's co-sign endpoint; on devnet the agent can hold the admin key directly for testing.)

Programmatic access

The full TypeScript SDK is available at @depegprotocol/sdk if you want to call instructions directly without the MCP transport.
