Standard MCP

Standard MCP is an MCP server for The Standard Reserve on Robinhood Chain (chain id 4663). Anyone can connect and read markets: King of the Markets standings, token data, prices, leaderboards. With an MCP key, the same server also acts for an agent account: a contract you own, which your agent can trade from but never withdraw from.

The endpoint is https://www.standarmcp.dev/mcp. It speaks Streamable HTTP, for both the 2026-07-28 protocol and 2025-era clients.

Quickstart

1. Open the app → and connect your wallet. Sign the sign-in message (no transaction, no gas).
2. Set daily limits and the actions the agent may take, then create the account. One transaction.
3. Create an MCP key and paste the config for your client. The key is shown once.
4. Top up the account with USDG and a little ETH, then ask your agent: “What's my Standard balance?”

Clients

Replace <YOUR_KEY> with your MCP key. Without the header, the server lists only the read tools.

Agent tools

Listed only with a valid key. Tools that move funds simulate first, check your balance, today's limit and the allowed actions, then send one transaction from the agent key and wait for it. Errors come back as plain sentences the agent can relay.

Security model

Your agent account is an AgentAccount contract, a minimal clone created by the factory for your wallet. It has two roles. The owner (your wallet) can do anything: withdraw, change limits, switch actions on or off, replace the agent key, pause and resume, and make any call from the account. The agent key can only call typed trading functions.

• Every agent action pays out to the account itself. No function the agent can call takes a recipient.
• Swaps only route through Standard Reserve pools: the three stock pools, launchpad pools and the ETH/USDG pool. Any other pool is refused, so the agent can't trade into a pool someone set up to drain it.
• Trades must start or end in USDG or ETH, so the spending limits always apply.
• The only value the agent can move out is ETH to its own key for gas, capped per day.
• No admin, no upgrade path, no fee. The contracts are not audited.

Limits and actions

The contract measures the account's USDG and ETH (with WETH) before and after every agent action. Whatever went out counts against today's limit; if an action would pass it, the whole transaction reverts. Sales and withdrawn liquidity bring funds back and never use the allowance. Limits reset at 00:00 UTC.

Keys

There are two kinds of keys. MCP keys (smcp_live_…) let a client use the server for your account. We store only their SHA-256 hash; revoking one takes effect on the next request. The agent key is the Ethereum key that signs the agent's transactions. It is generated on our server and stored encrypted (AES-256-GCM); it never leaves the server and is never shown.

If a key leaks, the worst case is trading inside today's limits until you act. Revoke the MCP key, or pause the agent and replace the agent key from the dashboard: one setAgent transaction and the old key can no longer do anything.

Points and rewards

King of the Markets credits a trade's points to the wallet that signs it, which is your agent key. A trade scores for the team of the stock it routes through: SPCX for the USA, BABA for China, SKHY for Korea, WETH pairs for ETH. Tokens your agent launches are created by the account, which earns the creator's share of trading fees. USDG paid to the agent key can be swept into the account from the dashboard.

Run it yourself

The same tools run locally over stdio with your own agent key: create an account whose agent is a key you hold, then point your client at the stdio server. The key never leaves your machine.
