BlockRun MCP Live Data

Skill by ara.so — MCP Skills collection.

BlockRun MCP provides real-time data access for AI agents through pay-per-call micropayments. No API keys, no subscriptions — just a USDC wallet and fractions-of-a-cent per query. Access markets, research, crypto, X/Twitter, on-chain data, LLMs, image/video generation, voice calls, and more.

What It Solves

Before BlockRun, Claude and other AI agents cannot answer:

"What's the current Polymarket probability for Bitcoin hitting $100k?"
"Find top 5 RAG papers from the last 30 days"
"What's the 24h volume on PEPE/ETH on Uniswap?"
"What are people saying about @sama on X?"

After installing BlockRun MCP, all these queries work — billed from a local USDC wallet at $0.001–$0.10 per call depending on the tool.

Installation

Prerequisites

Node.js ≥ 18
~$5 USDC on Base or Solana (auto-wallet created on first run)
MCP client (Claude Code, Claude Desktop, Cursor, Windsurf, ChatGPT Desktop)

Claude Code (Recommended)

claude mcp add blockrun -s user -- npx -y @blockrun/mcp@latest

The -s user flag installs globally. The -- separator ensures -y is passed to npx.

Claude Desktop

Add to claude_desktop_config.json:

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

Cursor

Add to ~/.cursor/mcp.json (macOS/Linux) or %APPDATA%\Cursor\mcp.json (Windows):

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

Windsurf

Same JSON format in:

macOS: ~/.codeium/windsurf/mcp_config.json
Linux: ~/.config/.codeium/windsurf/mcp_config.json
Windows: %APPDATA%\Codeium\windsurf\mcp_config.json

Wallet Setup & Funding

On first run, BlockRun auto-creates a wallet. Get your address:

Use blockrun_wallet tool with action: "balance"

Response includes your wallet address and balance. Send USDC on Base network:

Method	Instructions
Coinbase	Send → USDC → Base network → paste address
Bridge	Use bridge.base.org

Common Patterns

Multi-Agent Research with Budget Caps

Before spawning child agents, allocate per-agent budget to prevent runaway costs:

// Parent allocates budget
{
  "tool": "blockrun_wallet",
  "action": "delegate",
  "agent_id": "crypto-researcher",
  "agent_limit": 0.50
}

// Child agent queries with agent_id
{
  "tool": "blockrun_chat",
  "messages": [{"role": "user", "content": "Analyze Base L2 metrics"}],
  "model": "anthropic/claude-3.5-sonnet",
  "agent_id": "crypto-researcher"
}

{
  "tool": "blockrun_surf",
  "path": "onchain/sql",
  "body": {
    "sql": "SELECT COUNT(*) FROM base.transactions WHERE block_time > now() - interval '7 days'"
  },
  "agent_id": "crypto-researcher"
}

Child is auto-blocked when budget hits zero.

Free-Tier Drafting

Use free tools for scaffolding before paying for premium:

// Free price check
{
  "tool": "blockrun_price",
  "symbol": "ETH/USD"
}

// Free DEX data
{
  "tool": "blockrun_dex",
  "pair": "ETH/USDC",
  "chain": "base"
}

// Free LLM draft
{
  "tool": "blockrun_chat",
  "messages": [{"role": "user", "content": "Draft summary"}],
  "mode": "free"  // NVIDIA free tier
}

// Then upgrade to paid model
{
  "tool": "blockrun_chat",
  "messages": [{"role": "user", "content": "Refine this summary: ..."}],
  "model": "openai/gpt-4o"
}

Research Paper → Summary Flow

// 1. Search for papers
const searchResult = {
  "tool": "blockrun_exa",
  "action": "search",
  "query": "retrieval-augmented generation improvements",
  "type": "papers",
  "num_results": 5,
  "start_published_date": "2025-03-01"
}
// Returns: [{ url, title, published_date, ... }]

// 2. Get full content
const contentResult = {
  "tool": "blockrun_exa",
  "action": "contents",
  "urls": [/* URLs from search */],
  "text": true
}
// Returns: [{ url, text }]

// 3. Summarize with LLM
{
  "tool": "blockrun_chat",
  "messages": [
    {"role": "user", "content": `Summarize key improvements in these papers:\n\n${contentResult.map(c => c.text).join('\n---\n')}`}
  ],
  "model": "anthropic/claude-3.5-sonnet"
}

Prediction Market Odds → Decision

// 1. Search events
const events = {
  "tool": "blockrun_markets",
  "path": "polymarket/events",
  "query": {
    "search": "Bitcoin 100k 2026",
    "limit": 3
  }
}
// Returns: [{ id, title, markets: [{ id, outcome, price }] }]

// 2. Get historical candles
const candles = {
  "tool": "blockrun_markets",
  "path": "polymarket/candles",
  "query": {
    "market_id": events[0].markets[0].id,
    "interval": "1d",
    "limit": 30
  }
}
// Returns: [{ time, open, high, low, close, volume }]

// 3. Analyze with LLM
{
  "tool": "blockrun_chat",
  "messages": [
    {"role": "user", "content": `Current odds: ${events[0].markets[0].price}. 30-day trend: ${JSON.stringify(candles)}. Should I hedge?`}
  ],
  "model": "openai/gpt-4o"
}

Image Generation with Text Overlay

Use the 5-section framework from skills/image-prompting/SKILL.md:

{
  "tool": "blockrun_image",
  "action": "generate",
  "prompt": `
Subject: BlockRun logo + "GPT-5.5 NOW LIVE" headline
Style: Retro-futuristic, synthwave, neon pink/blue gradients
Composition: Centered logo, bold sans-serif headline below, dark space background
Technical: 4K resolution, high contrast, sharp text edges
Text: Ensure "GPT-5.5 NOW LIVE" is perfectly legible, no typography errors
  `,
  "model": "openai/gpt-image-2",
  "size": "1024x1024"
}

Voice Call Workflow

// 1. Buy number (one-time)
const numberResult = {
  "tool": "blockrun_phone",
  "path": "phone/numbers/buy",
  "body": { "area_code": "415" }
}
// Returns: { phone_number: "+14155559999" }

// 2. Make call
const callResult = {
  "tool": "blockrun_phone",
  "path": "voice/call",
  "body": {
    "to": "+14155551234",
    "task": "Remind them about tomorrow's meeting at 10am. Ask if they need directions.",
    "from": numberResult.phone_number
  }
}
// Returns: { call_id: "call_abc123" }

// 3. Poll status (repeat until completed/failed)
{
  "tool": "blockrun_phone",
  "path": `voice/call/${callResult.call_id}`
}
// Returns: { status: "in-progress" | "completed" | "failed", transcript, ... }

Critical Best Practices for LLM Agents

Payment/Balance Errors: When ANY blockrun_* tool returns a 402 payment error, call blockrun_wallet action "balance" FIRST to check status, then "setup" to get funding instructions. Do NOT retry the failing tool blindly.
Endpoint Catalogs: For blockrun_markets and blockrun_surf, the 80+ endpoint catalogs live in skills/markets/SKILL.md and skills/surf/SKILL.md, NOT in the tool description. Browse the skill before guessing paths.
Smart Routing: blockrun_chat routing:"smart" (ClawRouter) ONLY works on Base wallets. On Solana, pass mode: or model: to pick a model directly.
Async Jobs: blockrun_music and blockrun_video are payment-on-completion async. Failures or client timeouts do NOT charge. Don't retry-loop — they may take 60–180s.
Agent Budgets: Before spawning child agents, allocate per-agent budget via blockrun_wallet action:"delegate". Pass agent_id:"X" to every downstream blockrun_* call — child auto-blocked at zero.
Free Tier First: Use blockrun_chat mode:"free" (NVIDIA), blockrun_dex, blockrun_price (crypto/FX/commodity), and blockrun_models (all $0) for drafts before paying for premium models.

Troubleshooting

"Insufficient balance" Error

// Check wallet
{
  "tool": "blockrun_wallet",
  "action": "balance"
}
// Fund via displayed address

// Get QR code
{
  "tool": "blockrun_wallet",
  "action": "setup"
}

"Unknown endpoint" on blockrun_markets or blockrun_surf

The endpoint catalog is NOT in the tool description. Check:

skills/markets/SKILL.md for Polymarket/Kalshi/etc paths
skills/surf/SKILL.md for Surf's 84 endpoints

Smart Routing Fails on Solana Wallet

routing:"smart" only works on Base. Use explicit mode: or model::

{
  "tool": "blockrun_chat",
  "messages": [{"role": "user", "content": "Hello"}],
  "mode": "balanced"  // not routing: "smart"
}

Video/Music Generation Times Out

This is normal for 60–180s jobs. Do NOT retry immediately — the job may still be processing and you won't be charged for client-side timeouts. Wait or poll status if the tool supports it.

Agent Exceeds Budget

Check delegation:

{
  "tool": "blockrun_wallet",
  "action": "balance"
}
// Shows per-agent spending

Increase or reset:

{
  "tool": "blockrun_wallet",
  "action": "delegate",
  "agent_id": "research-agent-1",
  "agent_limit": 2.00  // new limit
}

Cost Optimization Tips

Use free tools first: blockrun_price (crypto/FX/commodity), blockrun_dex, blockrun_models, blockrun_chat mode:"free"
Batch requests: Single blockrun_surf SQL query can replace multiple blockrun_rpc calls
Cache aggressively: Don't re-fetch static data (e.g., model catalog, historical candles)
Set agent budgets: Prevent runaway loops with blockrun_wallet delegate
Preview before video/music: Use blockrun_image for storyboards (~~$0.05) before committing to blockrun_video (~~$1–3)

When NOT to Use BlockRun

High-volume single-API (≥10k calls/day): Direct subscriptions amortize better
Compliance/invoice requirements: USDC settlement isn't a tax invoice
Sub-100ms latency critical: x402 adds ~200–500ms overhead
Single source forever: If you only need Polymarket, skip the indirection

Use BlockRun for exploration, aggregation, or agent-driven workloads where you can't predict which source you'll need.
