Safe Block Lottos MCP for Base tickets and Base or Polygon jackpot reads.

VerifiedSTDIODesktop onlyFinanceSecurity & Monitoring

Overview

AI-generated overview

Reads Block Lottos lottery data on Base and Polygon and prepares one bounded Base ticket purchase in USDC, with wallet-signed confirmation.

What you can do
  • Read jackpot, stats, draw history and draw proofs for Base or Polygon
  • Look up a wallet's tickets and check whether it has won prizes
  • Prepare and confirm a single bounded Base ticket purchase in USDC
  • Register or manage a shared referral profile, including payout wallet, via a signed challenge
  • Report server capabilities and available tools and resources
When to use it
Use when an assistant should read Block Lottos jackpot, draw and wallet data, or walk a wallet owner through preparing one 1 USDC Base ticket with explicit approval. Not suited to anyone expecting a way to predict or guarantee draw outcomes.
Requirements
Runs locally over stdio as the PyPI package blocklottos-mcp, launched with uvx or installed with pip, so Python is needed. No API key or environment variables are declared. A wallet is needed for ticket purchase and referral signing; Base ETH is needed for gas.
Before you install
Purchases spend real money: one Base ticket costs 1 USDC plus gas, and outcomes are uncertain. Transactions are left unsigned and need the wallet owner's approval or a bounded, revocable spending policy. The referral flow asks for an EVM signature and returns a one-time management token that must be stored securely. Lottery participation is legally restricted by age and jurisdiction.

Installation

In SourceWeft

  1. Open Block Lottos in the dashboard and add it to a workspace.
  2. 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

Block Lottos Agent Tools

A public, open-source MCP server and cross-agent skill for safely reading Block Lottos data and preparing one bounded Base Future Ledger ticket.

mcp-name: com.blocklottos/blocklottos

Truthful positioning

Block Lottos can be presented as a weekly probability challenge, but not as a solvable equation. Six winning numbers will be drawn, yet a random future draw has no known equation that agents can solve to reveal those numbers in advance. Agents may analyze history, simulate, select numbers, submit an eligible lottery entry, and verify the result, but must never claim certainty or conceal the lottery and ticket cost.

Canonical economics

  • One Base ticket costs exactly 1 USDC.
  • Official Base USDC is the payment token.
  • Base ETH is required only for gas.
  • Effective minimum winner payout: 100 USDC on Base.
  • Effective minimum winner payout: 100 POL on Polygon.
  • A higher live on-chain jackpot applies.
  • Lottery outcomes are uncertain and no ticket is guaranteed to win.

Included

  • MCP server with ten tools and two resources.
  • Cross-agent skill: skills/block-lottos-probability-challenge/SKILL.md.
  • Safety validation for chain, token, contract, price, calldata, approval, wallet, receipt, and payout policy.
  • Tests for MCP protocol discovery, hostile responses, payout floors, and skill truthfulness.

Install the skill

Canonical skill URL:

https://blocklottos.com/skills/block-lottos-probability-challenge/SKILL.md

Hermes

bash
mkdir -p ~/.hermes/skills/block-lottos-probability-challengecurl -fsSL https://blocklottos.com/skills/block-lottos-probability-challenge/SKILL.md \  -o ~/.hermes/skills/block-lottos-probability-challenge/SKILL.md

Start a new Hermes session so the skill loader discovers it.

OpenClaw

Run from the OpenClaw workspace:

bash
mkdir -p skills/block-lottos-probability-challengecurl -fsSL https://blocklottos.com/skills/block-lottos-probability-challenge/SKILL.md \  -o skills/block-lottos-probability-challenge/SKILL.md

Start a new OpenClaw session so it loads the workspace skill.

Claude Code, Codex, Cursor, and other Agent Skills-compatible runtimes

Download the canonical SKILL.md into that runtime's supported skill directory. The file follows the open Agent Skills SKILL.md format and contains no credentials or executable installer.

A versioned source archive is also available at:

https://blocklottos.com/downloads/blocklottos-agent-tools-v1.0.0.zip

Run the MCP

Install from the Python Package Index:

bash
python -m pip install blocklottos-mcp

Or launch the standard-input/output MCP without a permanent installation:

bash
uvx blocklottos-mcp

The public Block Lottos Git mirror remains available as a source fallback:

bash
uvx --from git+https://blocklottos.com/git/blocklottos-agent-tools.git blocklottos-mcp

Hermes configuration

Add this to ~/.hermes/config.yaml, then restart Hermes:

yaml
mcp_servers:  block_lottos:    command: uvx    args:      - blocklottos-mcp    timeout: 30    connect_timeout: 60    sampling:      enabled: false

Hermes exposes the tools with names such as mcp_block_lottos_get_jackpot.

Generic MCP clients

Configure a standard-input/output server with:

  • Command: uvx
  • Arguments: blocklottos-mcp

No API key is required. Financial transactions remain unsigned and require the wallet owner's approval or an explicit, bounded, revocable spending policy.

MCP tools

  • get_capabilities
  • get_jackpot for Base or Polygon
  • get_stats
  • get_draw_history
  • get_draw_proof
  • get_wallet_tickets
  • check_wallet_prizes
  • get_or_create_referral — registers or securely manages the one shared human/agent affiliate profile. First request a challenge, sign it with the EVM identity wallet, and resubmit the signature. Cardano is supported as a payout wallet. Store the one-time management token securely; it is required for payout-wallet changes and private pending/paid balance monitoring.
  • prepare_ticket_purchase
  • confirm_ticket_purchase

Development

bash
python3.12 -m venv .venv.venv/bin/python -m pip install -e '.[test]'.venv/bin/pytest -q

Safety and eligibility

Only participate when the wallet owner meets the legal age requirement and lottery participation is permitted in their jurisdiction. Never chase losses, silently increase limits, use unlimited approvals, imply guaranteed winnings, or represent a random draw as a solved mathematical equation.
