100pro Token Risk

100pro Token Risk Screen — MCP server

Pre-trade risk screening for EVM token contracts and Solana SPL mints, exposed as a remote MCP tool. Honeypot/tax/owner flags, LP-lock state, mint & freeze authority, transfer fee/hook, holder concentration, liquidity depth, wash-trade signals — ending in a one-line Verdict.

• Endpoint: https://x402.rendraputra.dev/mcp (MCP streamable HTTP, JSON-RPC 2.0)
• Tool: token_risk_screen (token, chain) — read-only, up to 5 comma-separated addresses per call
• Chains: base, ethereum, bsc, polygon, arbitrum, solana
• Price: $0.10 USDC per single token, $0.25 for a 2-5 token batch, on Base, paid with x402 v2 — no account, no API key, no subscription. An unpaid call answers HTTP 402 with the payment challenge; pay it and retry. Free metadata: /llms.txt, /openapi.json, /.well-known/x402.

Use it as a remote MCP server (no install)

{

"mcpServers": { "100pro-token-risk": { "type": "http", "url": "https://x402.rendraputra.dev/mcp" } } }

Use it through this stdio bridge

Some clients only speak stdio. This tiny proxy forwards initialize, tools/list and tools/call to the remote endpoint (stdlib only, no dependencies):

{

"mcpServers": { "100pro-token-risk": { "command": "python3", "args": ["/absolute/path/to/100pro_mcp.py"] } } }

or straight from the repo, if you use uv:

{

"mcpServers": { "100pro-token-risk": { "command": "uvx", "args": ["--from", "git+https://github.com/rndrpp/100pro-mcp", "100pro-mcp"] } } }

What a call returns

A markdown report per token, e.g.:

## 0x8335…2913 (base)

Verdict: PASS — no blocking risk signal found. ...

If the call is unpaid the server answers with the x402 payment challenge (HTTP 402). Pay $0.10 USDC (single token) or $0.25 (2-5 token batch) on Base to the payTo in the challenge and retry; the response carries a PAYMENT-RESPONSE receipt naming the settled transaction.

Why paying beats a free scanner

Free scanners are the product being sold elsewhere: rate-limited, delay-baiting, or an upsell funnel. This one is a single priced call with a fail-closed guarantee — the report is generated and returned only after the USDC transfer is confirmed on Base, and every settle attempt is logged with the on-chain verdict.

Repo layout

• 100pro_mcp.py — repo-root entry point (python3 100pro_mcp.py, and the file container checkers execute after cloning); it bootstraps pro100/bridge.py.
• pro100/bridge.py — the actual stdio bridge: answers initialize / tools/list locally (so introspection needs no network) and forwards tools/call to the hosted endpoint.
• pyproject.toml — packages pro100, console script 100pro-mcp (so uvx --from git+https://github.com/rndrpp/100pro-mcp 100pro-mcp works).

Python 3.9+, standard library only — nothing to install for the plain-script path.
