AtlasYield

Independent judgment on DeFi vaults for agents: 16-factor Atlas Score with factor breakdown for 500+ vaults (Morpho, Aave, Pendle, Yearn, Beefy, Euler across Ethereum, Base, Arbitrum, Optimism, BNB), open blowup alerts, and route survival: whether a deposit can be exited at size today, measured by a real USDC round trip. NO_ROUTE returns blocking:true so the agent is told not to deposit. Read-only, keyless, no custody. npx -y @atlasyield/mcp

Documentation

@atlasyield/mcp

Read-only MCP server for the AtlasYield judgment layer. Six tools, no key, no custody, no execution: an agent asks for judgment and is told when a route is unsafe.

Tool	Answers
`get_vault_score`	Latest 16-factor Atlas Score for one vault (composite, label, 4 pillars, live APY/TVL).
`get_coverage`	What is scored right now: vault count, TVL, score spread, by protocol and chain.
`check_route_survival`	Can a deposit be exited at size, measured today? `blocking:true` means refuse.
`list_open_alerts`	Open blowup-monitor alerts from the published daily snapshot.
`explain_vault_score`	Why: all 16 factors by pillar (sub-score, weight, raw input, label) and the three weakest.
`compare_vaults`	2-8 vaults side by side, ranked by composite; unscored ones stay visible as `found:false`.

Data comes from the public API https://api.atlasyield.club/v1 and the published score history https://github.com/gveshk/atlasyield-score-history. Scored every 4 hours, snapshot published daily. Research and information, not investment advice.

Install

Claude Code:

claude mcp add atlasyield -- npx -y @atlasyield/mcp

Claude Desktop / Cursor / any stdio client (mcp.json or claude_desktop_config.json):

{
  "mcpServers": {
    "atlasyield": { "command": "npx", "args": ["-y", "@atlasyield/mcp"] }
  }
}

From a checkout: npm install && npm run build then use "command": "node", "args": ["<checkout>/dist/index.js"].

Try it

Is Morpho WETH on Base (0x09832347586e238841f49149c84d121bc2191c53) safe to enter at $10k?

The agent calls get_vault_score, then check_route_survival. A NO_ROUTE verdict comes back as blocking: true and a plain-English refusal.

Without an MCP client: npm run build && node scripts/smoke.mjs check_route_survival '{"chainId":8453,"address":"0x..."}' speaks raw JSON-RPC to the binary over stdio.

Environment

ATLAS_API_BASE — override the API base (default https://api.atlasyield.club/v1)
ATLAS_SNAPSHOT_BASE — override the score-history raw base

What this is not

No deposit, sign, or send tool exists here and none will be added. Execution, if offered, is a separate API with its own guards (recipient-safety, assertRouteValue) — never an MCP tool.
