## Common questions

### What is the Lincoln MCP server?

Lincoln is an MCP server listed in the public MCP registry as io.github.LincolnProtocol-com/lincoln. Private balance on Robinhood Chain for AI agents: send, swap and withdraw ETH, USDG and stocks. This page covers its npm package (@lincolnprotocol/mcp).

### Is the Lincoln MCP server safe to use?

Lincoln scores 72 out of 100 on VerifyMCP. We recorded 7 known advisories against it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Lincoln MCP server expose?

Lincoln exposes 11 tools: lincoln_balance, lincoln_address, lincoln_pools, lincoln_policy, lincoln_activity, and 6 more. Their descriptions and schemas cost roughly 799 tokens of context every time the server is loaded.

### Is the Lincoln MCP server still maintained?

Lincoln is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Lincoln MCP server under?

Lincoln declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
