Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account LincolnProtocol-com for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Lincoln gives an AI assistant its own private balance on Robinhood Chain, letting it check funds, quote, send, swap, withdraw and deposit ETH, USDG and token-st

What you can do: Check the agent wallet's private balance, address, status and activity history, and list available pools and spending policy limits. Request quotes for transfers and trades, then send, swap, withdraw or deposit ETH, USDG and tokenized stocks using a quote identifier rather than raw amounts. Proofs are generated locally and submitted by a relayer so the wallet does not appear on chain.
When to use it: Use it when an assistant needs to hold and move funds or tokenized stocks on Robinhood Chain privately, for example paying for services or rebalancing a small agent balance. Not needed if the assistant only reads public chain data.
Requirements: Runs locally via npx (Node.js) over stdio. Requires an agent wallet created with the Lincoln CLI and the LINCOLN_PASSPHRASE secret to unlock it; LINCOLN_HOME optionally sets the wallet directory (default ~/.lincoln). Network access to Robinhood Chain and the relayer is needed.

Before you install

The passphrase unlocks a wallet holding real funds, so treat it as a secret and keep only what the agent needs in the balance. Spending limits come from a local policy file enforced by this software, not by the contracts, so they can be bypassed if the software or file is tampered with. Send, swap, withdraw and deposit move money and are irreversible; review quotes before approving. Proofs and transactions go to a third-party relayer.

Installation

In SourceWeft

Open Lincoln in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@lincolnprotocol/mcp

MCP server that gives an AI agent its own private balance on Robinhood Chain through Lincoln. It can hold ETH, dollars and tokenized stocks, and send, swap and withdraw them. Proofs are generated on your machine and a relayer submits them, so the agent's wallet never appears on chain.

Tools: lincoln_balance, lincoln_address, lincoln_pools, lincoln_policy, lincoln_activity, lincoln_status, lincoln_quote, and lincoln_send / lincoln_swap / lincoln_withdraw / lincoln_deposit, which take a quoteId, never raw amounts.

Spends are checked against ~/.lincoln/policy.json (per-transaction, daily and approval limits). Those limits are enforced by this software, not by the contracts, so keep only what the agent needs in its balance.
