Scry MCP server

scry-mcp

A keyless, custody-free MCP server that bridges AI agents to Scry — Solana wallet intelligence paid per request via x402.

It holds no private keys and never moves funds. Free discovery tools are proxied directly; for paid evidence it hands the agent the exact x402 endpoint URL and price, and the agent settles the USDC payment with its own wallet against the Scry HTTPS API.

Tools

What agents can ask

Scry is most useful when an agent already knows the research object and needs a bounded evidence route rather than a generic score:

coverage, provenance, freshness, and caveats.

• Solana wallet forensics: resolve the full one-wallet evidence dossier with

upstream funders, hop depth, and freshness before payment.

• Solana wallet source of funds: find the funding-lineage route and inspect

spending on individual wallet dossiers.

• Pump.fun wallet cohort risk: select the cohort-screening route before

Example prompts:

Check whether this Solana wallet is covered by Scry before I approve a paid dossier.

Find the Scry route for tracing who funded a Solana wallet. Show the exact price,
input object, and caveats, but do not pay.

Resolve the Scry Pump.fun wallet-cohort evidence route and explain what it is not for.

Install (Claude Desktop / Cursor / any MCP client)

{
  "mcpServers": {
    "scry": { "command": "npx", "args": ["-y", "scry-mcp"] }
  }
}

Requires Node.js >= 20. No API keys, no account, no wallet configuration for the free tools. To actually pay for evidence, your agent needs its own x402 payment layer (for example an x402 client wallet); this bridge only tells it where and how much.

Security posture

are settled by the agent's own wallet directly against the Scry HTTPS API.

• No custody, no secrets: the server never holds keys or funds; paid calls

(32-44 chars) and are URL-encoded; ambiguous product ids are rejected with a candidate list instead of silently resolving to the wrong (priced) endpoint.

• Strict input validation: wallet and mint arguments must be base58

(scry.solanahub.de); there is no way to point this server at another host.

• Read-only: all three tools are GET-only against one fixed host

(the official @modelcontextprotocol/sdk), no install scripts.

• Small and auditable: a single ~250-line file, one direct dependency

Why keyless

Scry's paid API is already hardened and settles x402 payments directly to its own receiver. This bridge deliberately does not re-implement that or custody funds — it exposes the free surfaces and brokers the paid ones, which keeps it zero-secret and safe to run anywhere.
